Description

Technical Field

[0001] The present disclosure relates to the field of biomedical engineering industry, and particularly relates to an isolation device for an automated drug dispensing system and an automated drug dispensing system. Background Art

[0002] Currently, in order to improve the drug dispensing efficiency, an automated drug dispensing system is often used for drug dispensing. The automated drug dispensing system generally includes a drug dispensing area and a storage area that are communicated with each other. The storage area is generally used for storing materials, and the drug dispensing area is generally used for preparing liquid medicine. During the preparation of the liquid medicine, the drug dispensing area may be contaminated by splashing of the liquid medicine, and even cross-contamination of pollutants between the drug dispensing area and the storage area may occur.

[0003] In the prior art, a way of setting an air curtain between the drug dispensing area and the storage area is often adopted to reduce the cross-contamination of pollutants between the drug dispensing area and the storage area.

[0004] However, the blowing direction of the air curtain for liquid pollutants is uncontrollable, which may cause some liquid pollutants to enter the storage area, thus causing cross-contamination between the drug dispensing area and the storage area. In addition, some liquid pollutants may contain volatile components, and the volatile components become gaseous pollutants after volatilization. The air curtain can only reduce the diffusion speed of gaseous pollutants. In actual operation, generally, the working effect of the air curtain can be improved by increasing the wind speed of the air curtain. After increasing the wind speed, the pressure near the air curtain decreases, and the pressure in the drug dispensing area is greater than the pressure near the air curtain, thus aggravating the diffusion of gaseous pollutants in the drug dispensing area towards the air curtain, and the problem of cross-contamination of pollutants between the drug dispensing area and the storage area cannot be well solved. Summary of the Invention

[0005] The present disclosure is proposed in view of the above-mentioned prior art situation, and its purpose is to provide an isolation device for an automated drug dispensing system and an automated drug dispensing system for reducing the cross-contamination of pollutants between the drug dispensing area and the storage area.

[0006] To this end, a first aspect of the present disclosure provides an isolation device for an automated drug dispensing system. The automated drug dispensing system is a drug dispensing system that automatically mixes drugs in different containers. The automated drug dispensing system includes a dispensing area, a storage area for storing materials, and a picking device disposed in the dispensing area and capable of transporting materials from the storage area to the dispensing area. The isolation device is disposed between the dispensing area and the storage area. The isolation device includes a cloth, two reels, and a driving mechanism for driving the movement of the cloth. The cloth is provided with an opening through which the picking device shuttles between the dispensing area and the storage area. Two ends of the cloth are respectively disposed on the two reels, and the tension of the cloth is greater than a preset value. When the opening is wound around the reel, the dispensing area and the storage area are isolated from each other; when the opening is not wound around the reel, the dispensing area and the storage area are communicated through the opening.

[0007] In the isolation device according to the first aspect of the present disclosure, when the dispensing area and the storage area do not need to be communicated (for example, the picking device only works in the dispensing area), the opening is wound around the reel, and the cloth can isolate the dispensing area and the storage area, which is beneficial to reducing the cross-contamination of pollutants between the dispensing area and the storage area; when the dispensing area and the storage area need to be communicated (for example, the picking device transports materials between the dispensing area and the storage area), the opening is in a predetermined position for the picking device to shuttle through. Only communicating the dispensing area and the storage area through the opening can reduce the cross-sectional area of the channel formed between the dispensing area and the storage area, and can reduce the cross-contamination of pollutants (such as gaseous pollutants and liquid pollutants) between the dispensing area and the storage area; by adjusting the tension of the cloth to be greater than the preset value, the cloth can be in a tensioned state during movement or at rest (that is, the cloth that is not wound around the reel is in a non-creased state), which is beneficial to the cloth fitting to the plane adjacent to the cloth, and can improve the sealing effect of the cloth on the plane adjacent to the cloth, thereby reducing the cross-contamination of pollutants between the dispensing area and the storage area.

[0008] In addition, in the isolation device according to the first aspect of the present disclosure, optionally, the two reels are respectively a first reel and a second reel. Let the direction in which the cloth moves towards the first reel be the first direction, and let the direction in which the cloth moves towards the second reel be the second direction. In the working state, the cloth is in a tensioned state when at rest, or moving in the first direction or the second direction. In this case, the cloth in the working state is in a tensioned state during movement or at rest, and can minimize the cross-contamination between the dispensing area and the storage area during the execution of the drug dispensing task.

[0009] In addition, in the isolation device according to the first aspect of the present disclosure, optionally, the isolation device includes a first motion mode for adjusting the rolled fabric to a tensioned state. Along the axial projection of the first reel and the second reel, the tangent point of the rolled fabric and the first reel is the first position, and the tangent point of the rolled fabric and the second reel is the second position. In the first motion mode, when the rolled fabric moves in the first direction, the speed of the rolled fabric at the first position is greater than the speed at the second position; when the rolled fabric moves in the second direction, the speed of the rolled fabric at the second position is greater than the speed at the first position. In this case, when the rolled fabric moves in the first direction, the speed of the rolled fabric at the first position is greater than the speed at the second position, that is, the speed at which the rolled fabric is wound by the first reel is greater than the speed at which it is released by the second reel. At this time, if the rolled fabric is not in a tensioned state, as the first reel winds, the rolled fabric can be gradually pulled to a tensioned state. After the rolled fabric reaches the tensioned state, the traction force generated when the first reel winds the rolled fabric acts on the rolled fabric near the second reel. Under this acting force, the speed at which the rolled fabric detaches from the second reel gradually tends to be the same as the speed at which it is wound by the first reel. At this time, the rolled fabric can continue to maintain the tensioned state; the same applies when moving in the second direction.

[0010] In addition, in the isolation device according to the first aspect of the present disclosure, optionally, one end of the fabric roll is fixedly connected to the first reel, and the other end is movably connected to the second reel. When the fabric roll moves in the first direction, the first reel rotates in the third direction, and the second reel rotates in the fourth direction opposite to the third direction. The speed of the fabric roll at the first position is greater than that at the second position. When the fabric roll moves in the second direction, the second reel rotates in the fourth direction, and the first reel rotates in the fourth direction. The speed of the fabric roll at the second position is greater than that at the first position. In this case, since one end of the fabric roll is fixedly connected to the first reel, the fabric roll near the first reel will move in the same way as the rotation of the first reel (being wound or released based on the rotation direction of the reel). The fact that the other end of the fabric roll is movably connected to the second reel causes the fabric roll near the second reel to move mainly under the action of the frictional force generated between the second reel and the fabric roll during the rotation of the second reel. When the fabric roll moves in the first direction or the second direction, the second reel rotates in the fourth direction. That is to say, the second reel provides a frictional force in a constant direction. At this time, the main factors affecting the movement direction of the fabric roll are the rotation direction of the first reel and the winding and unwinding speed of the first reel relative to the second reel on the fabric roll. When the first reel and the second reel rotate in the same direction (the fourth direction), the fabric roll moves in the second direction and the speed at the second position is greater than that at the first position. At this time, the frictional force provided by the second reel will actually form a pulling force for winding the fabric roll, and the slow release of the first reel will form a resistance to the fabric roll. As the second reel winds, the fabric roll can be gradually pulled to a tensioned state. On the contrary, when the two reels rotate in opposite directions, the fabric roll moves in the first direction and the speed of the fabric roll at the first position is greater than that at the second position. At this time, the rapid winding of the first reel will form a pulling force on the fabric roll, and the frictional force provided by the second reel actually acts as a resistance to prevent the fabric roll from detaching from the second reel. As the first reel winds, the fabric roll can be gradually pulled to a tensioned state.

[0011] In addition, in the isolation device according to the first aspect of the present disclosure, optionally, both ends of the cloth roll are fixedly connected to the first reel and the second reel respectively. When the cloth roll moves in the first direction, the first reel rotates in the third direction, and the second reel rotates in the third direction. The speed of the cloth roll at the first position is greater than that at the second position. When the cloth roll moves in the second direction, the second reel rotates in the fourth direction, and the first reel rotates in the fourth direction. The speed of the cloth roll at the second position is greater than that at the first position. In this case, the cloth roll fixedly connected to the first reel and the second reel at both ends moves in the same way as the two reels rotate. The two reels rotate in the same direction to achieve the winding and releasing of the cloth roll. When the cloth roll moves in the first direction, the winding speed of the cloth roll by the first reel is greater than the releasing speed of the cloth roll by the second reel, so that the cloth roll can be pulled to move in the first direction. On the contrary, when the cloth roll moves in the second direction, the winding speed of the cloth roll by the second reel is greater than the releasing speed of the cloth roll by the first reel, so that the cloth roll can be pulled to move in the second direction.

[0012] In addition, in the isolation device according to the first aspect of the present disclosure, optionally, the driving mechanism includes a first driving mechanism for driving the first reel to rotate and a second driving mechanism for driving the second reel to rotate. The transmission ratio of the first driving mechanism to the first reel is equal to the transmission ratio of the second driving mechanism to the second reel. At least based on the relationship between the shaft diameters of the first reel and the second reel, the operating states of the first driving mechanism and the second driving mechanism during operation are adjusted. When the shaft diameters of the first reel and the second reel are equal, when the cloth roll moves in the first direction, the output torque of the first driving mechanism is greater than the output torque of the second driving mechanism, or the rotation speed of the first driving mechanism is greater than the rotation speed of the second driving mechanism. When the cloth roll moves in the second direction, the output torque of the second driving mechanism is greater than the output torque of the first driving mechanism, or the rotation speed of the second driving mechanism is greater than the rotation speed of the first driving mechanism. In this case, it is convenient to realize the setting of the movement direction and position of the cloth roll in the first movement mode, so that the cloth roll can be adjusted to a tensioned state.

[0013] In addition, in the isolation device according to the first aspect of the present disclosure, optionally, the isolation device has a second movement mode to make the cloth roll move at a constant speed. The first movement mode and the second movement mode are respectively configured to be applied before and / or during the working state. In this case, the movement mode of the isolation device can be adjusted based on the state of the cloth roll.

[0014] In addition, in the isolation device according to the first aspect of the present disclosure, optionally, the isolation device includes one or more windows and a position sensor. The storage area includes storage units arranged in one-to-one correspondence with the windows. The position sensor is configured to detect the position where the opening is located so that the opening is aligned with a predetermined window. In this case, the position sensor facilitates the precise alignment of the opening and the window, which is beneficial for the opening and the window that are aligned with each other to form a channel for communicating the medicine dispensing area and the storage area. The medicine dispensing area is only connected to the storage unit corresponding to the opening, which can reduce the contamination of the medicine dispensing area to the storage units that do not participate in material handling, thereby reducing the cross-contamination of pollutants between the medicine dispensing area and the storage area.

[0015] In addition, in the isolation device according to the first aspect of the present disclosure, optionally, the isolation device includes a fixing plate and two positioning shafts. The window is located on the fixing plate. The two positioning shafts include a first positioning shaft and a second positioning shaft. The two winding shafts include a first winding shaft and a second winding shaft. The first positioning shaft is located between the first winding shaft and the fixing plate, and the second positioning shaft is located between the second winding shaft and the fixing plate. And at least part of the winding cloth is located between the positioning shaft and the fixing plate. In this case, the position of the winding cloth can be restricted by the positioning shaft, which is beneficial for the winding cloth to fit on the fixing plate in both the stationary and moving states. In addition, the fixing plate can also provide an additional isolation barrier outside the window area, thereby improving the sealing effect of the winding cloth on the medicine dispensing area or the storage area, and further reducing the cross-contamination of pollutants between the medicine dispensing area and the storage area.

[0016] The second aspect of the present disclosure provides an automated medicine dispensing system, which includes a medicine dispensing area, a storage area for storing materials, a picking device, and the isolation device according to the first aspect of the present disclosure. In this case, an automated medicine dispensing system capable of reducing the cross-contamination of pollutants between the medicine dispensing area and the storage area can be provided.

[0017] According to the present disclosure, an isolation device and an automated medicine dispensing system for reducing the cross-contamination of pollutants between a medicine dispensing area and a storage area can be provided. Description of the Drawings

[0030] Hereinafter, with reference to the drawings, the preferred implementation manners of the present disclosure will be described in detail. In the following description, the same reference numerals are given to the same components, and repeated descriptions are omitted. In addition, the drawings are only schematic diagrams, and the dimensional ratios between components or the shapes of components, etc. may be different from the actual ones.

[0031] It should be noted that the terms "include" and "have" and any variations thereof in this disclosure, such as a process, method, system, product or device including or having a series of steps or units, do not necessarily limit to those steps or units clearly listed, but may include or have other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0032] It should be noted that in this text, relative position and relative direction terms such as "above", "towards above", "below", "towards below", "vertical direction", "left side", "towards left side", "left", "towards left", "right side", "towards right side", "right", "towards right", "horizontal direction", "front", "towards front", "rear", "towards rear", "longitudinal direction", etc. are with reference to the normal operating posture and should not be considered restrictive.

[0033] The first aspect of this disclosure relates to an isolation device for isolating the storage area and the dispensing area in an automated drug dispensing system. The isolation device can sometimes also be referred to as the isolation device of the automated drug dispensing system or the barrier device.

[0034] The second aspect of this disclosure relates to an automated drug dispensing system for automatically mixing drugs in different containers. This system can use the isolation device involved in this disclosure to isolate the storage area and the dispensing area in the automated drug dispensing system. The automated drug dispensing system can sometimes also be referred to as the drug dispensing system or the automated drug dispensing system with an isolation device.

[0035] In some examples, the automated drug dispensing system can include a dispensing area. In some examples, the dispensing area can be used for drug preparation and drug sub-packaging. Thus, drugs can be prepared.

[0036] In some examples, the automated drug dispensing system can include a storage area for storing materials. In some examples, the materials can include drugs, syringes or containers for holding drugs. In some examples, the storage area can be divided into a drug storage area, a syringe storage area or a container storage area. Thus, it is convenient to store different types of materials required during drug dispensing.

[0037] In some examples, the automated drug dispensing system can include a picking device. In some examples, the picking device can be arranged in the dispensing area. In some examples, the picking device can be used to transport materials from the storage area to the dispensing area. Thus, the materials in the storage area can be transported to the dispensing area for drug dispensing.

[0038] Hereinafter, with reference to the drawings, the isolation device 1 of the automated drug dispensing system and the automated drug dispensing system involved in this disclosure will be described in detail.

[0039] Figure 1 It is a schematic structural diagram showing the isolation device 1 involved in the examples of the present disclosure.

[0040] Refer to Figure 1 , in some examples, the automated drug dispensing system may include the isolation device 1. In some examples, the isolation device 1 may be provided between areas with high cleanliness requirements. In some examples, the isolation device 1 may be provided between the drug dispensing area and the storage area. Thus, pollution can be reduced through the isolation device 1 in areas with high clean environment requirements. In some examples, the automated drug dispensing system may include one or more isolation devices 1. Thus, different-sized target areas can be isolated through the isolation device 1. In some examples, multiple isolation devices 1 may be arranged side by side in the vertical or horizontal direction.

[0041] In some examples, the isolation device 1 may include a cloth roll 11 (refer to Figure 1 ). In some examples, the isolation device 1 may include two reels 12 (refer to Figure 1 ). In some examples, both ends of the cloth roll 11 may be respectively arranged on the two reels 12. In this case, compared with the method of setting a movable partition to isolate two areas, using the above-mentioned isolation device 1 to isolate two areas can save space; compared with the method of continuously using an air curtain for a long time, using the above-mentioned isolation device 1 can save energy consumption.

[0042] Figure 2 It is a front view schematic diagram showing the isolation device 1 involved in the examples of the present disclosure. Figure 3 It is a rear view schematic diagram showing the isolation device 1 involved in the examples of the present disclosure.

[0043] Refer to Figure 2 , in some examples, the cloth roll 11 may be provided with an opening 111 for the picking device to shuttle between the drug dispensing area and the storage area. In some examples, when the opening 111 is wound around the reel 12, the drug dispensing area and the storage area are isolated from each other; when the opening 111 is not wound around the reel 12, the opening 111 connects the drug dispensing area and the storage area. In this case, when the drug dispensing area and the storage area do not need to be connected (for example, the picking device only works in the drug dispensing area), the opening 111 is wound around the reel 12, and the cloth roll 11 can isolate the drug dispensing area and the storage area, which is beneficial to reducing the cross-contamination of pollutants between the drug dispensing area and the storage area; when the drug dispensing area and the storage area need to be connected (for example, the picking device transports materials between the drug dispensing area and the storage area), the opening 111 is in a predetermined position for the picking device to shuttle, and only connecting the drug dispensing area and the storage area through the opening 111 can reduce the cross-sectional area of the channel formed between the drug dispensing area and the storage area, and can reduce the cross-contamination of pollutants (such as gaseous pollutants and liquid pollutants) between the drug dispensing area and the storage area.

[0044] In some examples, the tension of the fabric roll 11 can be greater than a preset value. In some examples, the tension of the fabric roll 11 can be adjusted by setting different preset values. For example, when it is necessary to adjust the fabric roll 11 to a tensioned state (that is, the fabric roll 11 not wound on the reel 12 is in a non-creased state), a suitable preset value can be set based on the parameters of the fabric roll 11, and then the tension of the fabric roll 11 can be configured to be greater than the preset value. That is to say, the tension of the fabric roll 11 can be set to be greater than the preset value to make the fabric roll 11 in a tensioned state. In this case, by adjusting the tension of the fabric roll 11 to be greater than the preset value, the fabric roll 11 can be in a tensioned state during movement or rest (that is, the fabric roll 11 not wound on the reel 12 is in a non-creased state), which is beneficial for the fabric roll 11 to fit on the plane adjacent to the fabric roll 11, and can improve the sealing effect of the fabric roll 11 on the plane adjacent to the fabric roll 11, thereby reducing the cross-contamination of pollutants between the medicine dispensing area and the storage area.

[0045] In some examples, the preset value can be related to the self-parameters of the fabric roll 11, for example, it can be related to the material, area, aspect ratio, thickness, density or hardness of the fabric roll 11, etc.

[0046] In some examples, the isolation device 1 can include a tension sensor. In some examples, the tension sensor can be selected from a strain sensor, a piezoelectric sensor, an ultrasonic sensor, a capacitive sensor or a magnetosensitive sensor. Thus, it is beneficial to adjust the tension of the fabric roll 11. In some examples, the tension of the fabric roll 11 in a tensioned state can be measured by the tension sensor, and the measured tension test value can be used as the preset value. When the tension of the fabric roll 11 is greater than the preset value, it can be considered that the fabric roll 11 is in a tensioned state. At this time, the tension test value obtained by the tension sensor is also related to the self-parameters of the fabric roll 11, so it also belongs to the method of setting the preset value according to the self-parameters of the fabric roll 11 in the present disclosure.

[0047] Figure 4 is a top view schematic diagram showing the isolation device 1 involved in the examples of the present disclosure. Figure 5 is a schematic diagram showing the examples involved in the present disclosure Figure 4 of the enlarged view of area A in

[0048] See Figure 4 , in some examples, S1 can represent the medicine dispensing area, and S2 can represent the storage area. In other examples, S1 can represent the storage area, and S2 can represent the medicine dispensing area.

[0049] In some examples, the two reels 12 can include a first reel 121 (see Figure 4 ) and a second reel 122 (see Figure 4)。In some examples, the direction in which the fabric roll 11 moves towards the first reel 121 can be the first direction D1 (see Figure 2 ). The direction in which the fabric roll 11 moves towards the second reel 122 can be the second direction D2 (see Figure 2 ).

[0050] In some examples, in the working state, the fabric roll 11 can be in a tensioned state when it is stationary, or when it moves towards the first direction D1 or the second direction D2. In the present disclosure, the working state refers to the state in which the isolation device 1 has been debugged and can perform the medicine dispensing task. In this case, the fabric roll 11 in the working state is in a tensioned state whether it is moving or stationary, and can minimize the cross-contamination between the medicine dispensing area and the storage area as much as possible during the process of performing the medicine dispensing task.

[0051] In some examples, the isolation device 1 can include a first motion mode. In some examples, the first motion mode can be used to adjust the fabric roll 11 to a tensioned state. In this case, it is beneficial for the fabric roll 11 to fit on the plane adjacent to the fabric roll 11, and it is beneficial to improve the sealing effect of the fabric roll 11 on the plane adjacent to the fabric roll 11.

[0052] In some examples, along the axial projection of the first reel 121 and the second reel 122, the tangent point of the fabric roll 11 and the first reel 121 can be the first position P1 (see Figure 4 ), and the tangent point of the fabric roll 11 and the second reel 122 can be the second position P2 (see Figure 4 ). It should be specifically noted that the tangent point is the tangent point of the fabric roll 11 and the reel 12 in an ideal state (that is, the tangent point is obtained without considering the length, thickness of the fabric roll 11, and the surface roughness of the reel 12 and the fabric roll 11). The tangent point here may not be the tangent point between completely regular figures in mathematics.

[0053] In some examples, in the first motion mode, when the fabric roll 11 moves in the first direction D1, the speed of the fabric roll 11 at the first position P1 can be greater than the speed at the second position P2; when the fabric roll 11 moves in the second direction D2, the speed of the fabric roll 11 at the second position P2 can be greater than the speed at the first position P1. In this case, when the fabric roll 11 moves in the first direction D1, the speed of the fabric roll 11 at the first position P1 is greater than the speed of the fabric roll 11 at the second position P2, that is, the speed at which the fabric roll 11 is wound by the first reel 121 is greater than the speed at which it is released by the second reel 122. At this time, if the fabric roll 11 is not in a tensioned state, as the first reel 121 winds, the fabric roll 11 can be gradually pulled into a tensioned state. After the fabric roll 11 reaches the tensioned state, the traction force generated when the first reel 121 winds the fabric roll 11 acts on the fabric roll 11 near the second reel 122. Under this acting force, the speed at which the fabric roll 11 detaches from the second reel 122 gradually tends to be the same as the speed at which it is wound by the first reel 121. At this time, the fabric roll 11 can continue to maintain the tensioned state; the same is true when moving in the second direction D2.

[0054] In some examples, the isolation device 1 may include a driving mechanism 13 for driving the movement of the fabric roll 11 (see Figure 1 ). In some examples, the driving mechanism 13 may include a first driving mechanism 131 for driving the rotation of the first reel 121 (see Figure 1 ) and a second driving mechanism 132 for driving the rotation of the second reel 122 (see Figure 1 ).

[0055] In some examples, the fabric roll 11 may be subject to a traction force in the first direction D1 or the second direction D2, and a resistance force opposite to the direction of the traction force, and the traction force may be greater than the resistance force.

[0056] In some examples, in the first motion mode, when the fabric roll 11 moves in the first direction D1, the fabric roll 11 may be subject to a traction force in the first direction D1 applied by the first reel 121 and a resistance force in the second direction D2 applied by the second reel 122, and the traction force applied by the first reel 121 may be greater than the resistance force applied by the second reel 122. In this case, when the fabric roll 11 moves in the first direction D1, the traction force in the first direction D1 received by the fabric roll 11 is greater than the resistance force in the second direction D2, and the resultant force received by the fabric roll 11 is in the first direction D1, so that the fabric roll 11 can move in the first direction D1.

[0057] In some examples, in the first motion mode, when the fabric roll 11 moves toward the second direction D2, the fabric roll 11 may be subjected to a pulling force toward the second direction D2 applied by the second reel 122 and a resistance force toward the first direction D1 applied by the first reel 121. The pulling force applied by the second reel 122 may be greater than the resistance force applied by the first reel 121. In this case, when the fabric roll 11 moves toward the second direction D2, the pulling force on the fabric roll 11 toward the second direction D2 is greater than the resistance force toward the first direction D1, and the resultant force on the fabric roll 11 is toward the second direction D2, so that the fabric roll 11 can move toward the second direction D2.

[0058] In some examples, both ends of the fabric roll 11 may be movably or fixedly connected to the two reels 12 respectively. For example, one end of the fabric roll 11 may be fixedly or movably connected to the first reel 121, and the other end may be fixedly or movably connected to the second reel 122. In some examples, the movable connection mode between the fabric roll 11 and the reel 12 may be a socket connection. In some examples, the fixed connection mode between the fabric roll 11 and the reel 12 may be a threaded connection, a locking connection, a welding connection or an adhesive connection. Thereby, the connection stability between the fabric roll 11 and the reel 12 can be improved, and the risk of the fabric roll 11 falling off the reel 12 can be reduced.

[0059] In some examples, the isolation device 1 may include a locking mechanism. The locking mechanism may be disposed near the reel 12 that is movably connected to the fabric roll 11, and the locking mechanism may be used to fix the fabric roll 11 on the reel 12, and when the locking mechanism is released, the fabric roll 11 can be restored to a state of being movably connected to the reel 12.

[0060] In some examples, one end of the fabric roll 11 may be fixedly connected to the first reel 121, and the other end may be movably connected to the second reel 122. The following describes further solutions in this case.

[0061] In some examples, when the fabric roll 11 moves in the first direction D1, the first reel 121 can rotate in the third direction, and the second reel 122 can rotate in the fourth direction opposite to the third direction. The speed of the fabric roll 11 at the first position P1 can be greater than the speed at the second position P2. In some examples, when the fabric roll 11 moves in the second direction D2, the second reel 122 can rotate in the fourth direction, and the first reel 121 can rotate in the fourth direction. The speed of the fabric roll 11 at the second position P2 can be greater than the speed at the first position P1. In this case, since one end of the fabric roll 11 is fixedly connected to the first reel 121, the fabric roll 11 near the first reel 121 will move in the same manner as the rotation of the first reel 121 (wound or released based on the rotation direction of the reel 12); while the other end of the fabric roll 11 is movably connected to the second reel 122, which causes the fabric roll 11 near the second reel 122 to move mainly under the action of the frictional force generated between the second reel 122 and the fabric roll 11 during rotation; when the fabric roll 11 moves in the first direction D1 or the second direction D2, the second reel 122 rotates in the fourth direction. That is to say, the second reel 122 provides a frictional force in a constant direction. At this time, the factors affecting the movement direction of the fabric roll 11 are mainly the rotation direction of the first reel 121 and the winding and unwinding speed of the first reel 121 relative to the second reel 122 for the fabric roll 11; when the first reel 121 and the second reel 122 rotate in the same direction (the fourth direction), the fabric roll 11 moves in the second direction D2 and the speed at the second position P2 is greater than the speed at the first position P1. At this time, the frictional force provided by the second reel 122 will actually form a traction force for winding the fabric roll 11, and the slow unwinding of the first reel 121 will form a resistance to the fabric roll 11. As the second reel 122 winds, the fabric roll 11 can be gradually pulled to a taut state; conversely, when the two reels 12 rotate in opposite directions, the fabric roll 11 moves in the first direction D1 and the speed of the fabric roll 11 at the first position P1 is greater than the speed at the second position P2. At this time, the rapid winding of the first reel 121 will form a traction force for the fabric roll 11, and the frictional force provided by the second reel 122 actually acts as a resistance to prevent the fabric roll 11 from detaching from the second reel 122. As the first reel 121 winds, the fabric roll 11 can be gradually pulled to a taut state.

[0062] In some examples, the third direction can be clockwise or counterclockwise, and the fourth direction can be counterclockwise or clockwise corresponding to the third direction.

[0063] In some examples, when the fabric roll 11 moves in the first direction D1 or the second direction D2, the second driving mechanism 132 can be in the torque mode. The torque mode refers to a state where the output torque of the driving mechanism 13 is constant in magnitude and constant in rotational direction during operation. In this case, the movement direction of the fabric roll 11 can be adjusted only by adjusting the output torque and the rotational direction of the second driving mechanism 132, which facilitates mechanical debugging.

[0064] In some examples, when the fabric roll 11 moves in the first direction D1, the torque received by the fabric roll 11 at the first position P1 can be greater than the torque received by the fabric roll 11 at the second position P2. In some examples, when the fabric roll 11 moves in the second direction D2, the speed at the second position P2 can be greater than the speed at the first position P1. In this case, it is convenient to implement the settings regarding the movement direction and position of the fabric roll 11 in the first movement mode, so that the fabric roll 11 can be adjusted to a tensioned state. It should be specifically noted that the above working state can be obtained by debugging the output torque of the driving mechanism 13, the transmission ratio between the driving mechanism 13 and the reel 12, and the shaft diameter ratio of the first reel 121 and the second reel 122.

[0065] In some examples, both ends of the fabric roll 11 can be fixedly connected to the first reel 121 and the second reel 122 respectively. The following describes further solutions in this case.

[0066] In some examples, when the fabric roll 11 moves in the first direction D1, the first reel 121 can rotate in the third direction, the second reel 122 can rotate in the third direction, and the speed of the fabric roll 11 at the first position P1 can be greater than the speed at the second position P2. In some examples, when the fabric roll 11 moves in the second direction D2, the second reel 122 can rotate in the fourth direction, the first reel 121 can rotate in the fourth direction, and the speed of the fabric roll 11 at the second position P2 can be greater than the speed at the first position P1. In this case, the fabric roll 11 fixedly connected to the first reel 121 and the second reel 122 at both ends moves in the same way as the two reels 12 rotate, and the two reels 12 rotate in the same direction to realize the winding and releasing of the fabric roll 11; when the fabric roll 11 moves in the first direction D1, the speed of the first reel 121 winding the fabric roll 11 is greater than the speed of the second reel 122 releasing the fabric roll 11, so that the fabric roll 11 can be pulled to move in the first direction D1; conversely, when the fabric roll 11 moves in the second direction D2, the speed of the second reel 122 winding the fabric roll 11 is greater than the speed of the first reel 121 releasing the fabric roll 11, so that the fabric roll 11 can be pulled to move in the second direction D2.

[0067] In some examples, when the fabric roll 11 moves in the first direction D1, the torque received by the fabric roll 11 at the first position P1 can be greater than the torque received by the fabric roll 11 at the second position P2, or the speed of the fabric roll 11 at the first position P1 can be greater than the speed of the fabric roll 11 at the second position P2. In some examples, when the fabric roll 11 moves in the second direction D2, the torque received by the fabric roll 11 at the second position P2 can be greater than the torque received by the fabric roll 11 at the first position P1, or the speed of the fabric roll 11 at the second position P2 can be greater than the speed of the fabric roll 11 at the first position P1. In this case, it is convenient to implement the setting of the movement direction and position of the fabric roll 11 in the first movement mode, so that the fabric roll 11 can be adjusted to a tensioned state.

[0068] For a clearer description, taking the transmission ratio of the first driving mechanism 131 to the first reel 121 being equal to the transmission ratio of the second driving mechanism 132 to the second reel 122, and the shaft diameters of the first reel 121 and the second reel 122 being equal as an example, a detailed description is given.

[0069] In some examples, when the fabric roll 11 moves in the first direction D1, the output torque of the first driving mechanism 131 can be greater than the output torque of the second driving mechanism 132, or the rotational speed of the first driving mechanism 131 can be greater than the rotational speed of the second driving mechanism 132. In some examples, when the fabric roll 11 moves in the second direction D2, the output torque of the second driving mechanism 132 can be greater than the output torque of the first driving mechanism 131, or the rotational speed of the second driving mechanism 132 can be greater than the rotational speed of the first driving mechanism 131. In this case, it is convenient to implement the setting of the movement direction and position of the fabric roll 11 in the first movement mode, so that the fabric roll 11 can be adjusted to a tensioned state.

[0070] It should be noted that when selecting a solution where the transmission ratio of the first driving mechanism 131 to the first reel 121 is not equal to the transmission ratio of the second driving mechanism 132 to the second reel 122 or the shaft diameter of the first reel 121 is different from the shaft diameter of the second reel 122, those skilled in the art can make adaptive adjustments.

[0071] For example, when the transmission ratio of the first driving mechanism 131 to the first reel 121 is greater than the transmission ratio of the second driving mechanism 132 to the second reel 122 and the fabric roll 11 moves in the first direction D1, the output torque of the first driving mechanism 131 can be less than the output torque of the second driving mechanism 132. In this case, since the transmission ratio of the first driving mechanism 131 to the first reel 121 is greater than the transmission ratio of the second driving mechanism 132 to the second reel 122, the torque received by the fabric roll 11 at the first position P1 is still greater than the torque received by the fabric roll 11 at the second position P2 at this time, so that the tensioning of the fabric roll 11 can be achieved.

[0072] For example, when the transmission ratio of the first driving mechanism 131 to the first reel 121 is greater than that of the second driving mechanism 132 to the second reel 122, and the fabric roll 11 moves towards the second direction D2, the rotational speed of the first driving mechanism 131 can be greater than that of the second driving mechanism 132. In this case, since the transmission ratio of the first driving mechanism 131 to the first reel 121 is greater than that of the second driving mechanism 132 to the second reel 122, the speed of the fabric roll 11 at the second position P2 is still greater than that at the first position P1 at this time, so that the tension of the fabric roll 11 can be realized.

[0073] In some examples, preferably, one end of the fabric roll 11 can be fixedly connected to the first reel 121, and the other end is movably connected to the second reel 122. When the fabric roll 11 moves towards the first direction D1, the output torque of the first driving mechanism 131 can be greater than that of the second driving mechanism 132; when the fabric roll 11 moves towards the second direction D2, the rotational speed of the second driving mechanism 132 can be greater than that of the first driving mechanism 131. In this case, it can be realized that in the first motion mode, when the fabric roll 11 moves towards the first direction D1, the speed of the fabric roll 11 at the first position P1 is greater than that at the second position P2; when the fabric roll 11 moves towards the second direction D2, the speed of the fabric roll 11 at the second position P2 is greater than that at the first position P1.

[0074] In some examples, the first driving mechanism 131 can be equipped with a speed reducer. Thus, it is beneficial for the first driving mechanism 131 to output a larger torque. In some examples, the second driving mechanism 132 can be equipped with a speed reducer. Thus, it is beneficial for the second driving mechanism 132 to output a larger torque.

[0075] In some examples, the driving mechanism 13 can be a servo motor or a stepper motor. In some examples, the driving mechanism 13 can include a position controller to accurately control the rotation angle of the motor. In some examples, the position controller can be an encoder. Thus, the accuracy of releasing the length of the fabric roll 11 can be improved, which is beneficial for controlling the position of the fabric roll 11 through the driving mechanism 13.

[0076] In some examples, the transmission mode between the driving mechanism 13 and the reel 12 can be selected from synchronous belt drive, gear drive, chain drive or screw pair drive. Thus, it can be realized that the rotation of the reel 12 drives the movement of the fabric roll 11.

[0077] In some examples, the isolation device 1 can have a second motion mode. In some examples, the second motion mode can make the fabric roll 11 move at a constant speed. Thus, it is beneficial for the smooth movement of the fabric roll 11.

[0078] In some examples, the first motion mode and the second motion mode can be respectively configured to be applied before entering the working state and / or when in the working state. In this case, the motion mode of the isolation device 1 can be adjusted based on the state of the fabric roll 11.

[0079] In some examples, the isolation device 1 can maintain the first motion mode in the working state. Thus, it is beneficial to keep the fabric roll 11 in a tensioned state during operation.

[0080] In some examples, the fabric roll 11 is in a tensioned state before entering the working state, and the isolation device 1 can adopt the second motion mode before entering the working state or when in the working state. Thus, it is beneficial to keep the fabric roll 11 in a tensioned state. In some examples, the isolation device 1 can maintain the second motion mode in the working state and randomly insert the first motion mode. In this case, compared with keeping the fabric roll 11 tensioned all the time by the first motion mode, the internal tension of the fabric roll 11 can be reduced, thereby reducing the possibility of the fabric roll 11 breaking due to excessive internal tension, and randomly inserting the first motion mode is beneficial to keep the fabric roll 11 in a tensioned state during operation.

[0081] In some examples, the isolation device 1 can have a third motion mode. In some examples, the third motion mode can keep the fabric roll 11 in a stationary state. In some examples, the third motion mode can be configured to be applied before entering the working state and / or when in the working state.

[0082] In some examples, both ends of the fabric roll 11 can be fixedly connected to the first reel 121 and the second reel 122 respectively. In the third motion mode, the fixed connection points where both ends of the fabric roll 11 are connected to the two reels 12 can be subjected to acting forces. Thus, the fabric roll 11 can be kept in a tensioned state in the stationary state.

[0083] In some examples, one end of the fabric roll 11 can be fixedly connected to the first reel 121, and the other end can be movably connected to the second reel 122. In the third motion mode, the second reel 122 can be in a rotating state or have a tendency to rotate. The movable connection point between the fabric roll 11 and the second reel 122 can be subjected to frictional force, and the fixed connection point between the fabric roll 11 and the second reel 122 can be subjected to acting force. Thus, the fabric roll 11 can be kept in a tensioned state in the stationary state.

[0084] In some examples, the isolation device 1 can include one or more windows 14 (see Figure 3)。In some examples, the storage area may include storage units provided in one-to-one correspondence with the windows 14. In some examples, the storage area may include one or more storage units. Thus, when the picking device transports materials, only the storage unit corresponding to the opening 111 in the dispensing area is in communication, which can reduce the contamination of the dispensing area to the storage units that do not participate in material handling, thereby reducing the cross-contamination of pollutants between the dispensing area and the storage area.

[0085] Figure 6 is a first perspective schematic view of the isolation device 1 involved in the examples of the present disclosure. Figure 7 is a partial schematic view of the isolation device 1 involved in the examples of the present disclosure. Figure 8 is a schematic showing the involved in the examples of the present disclosure Figure 7 magnified schematic view of area B therein.

[0086] See Figure 6 , in some examples, the isolation device 1 may include a position sensor 15. In some examples, the position sensor 15 may be configured to detect the position where the opening 111 is located to facilitate the alignment of the opening 111 with a predetermined window. In this case, the position sensor 15 is conducive to the precise alignment of the opening 111 and the window 14, and is conducive to the opening 111 and the window 14 that are aligned with each other to form a channel for communication between the dispensing area and the storage area.

[0087] In some examples, the isolation device 1 may include one or more position sensors 15 provided in one-to-one correspondence with the windows 14. Thus, the alignment of the opening 111 and the predetermined window can be detected.

[0088] In some examples, the position sensor 15 may be a photoelectric sensor. In some examples, a plurality of detection holes 151 may be respectively formed at the upper and lower ends of the fabric roll 11 in the length direction (see Figure 8 ), and the position sensor 15 can determine the position of the fabric roll 11 through the detection holes 151. In some examples, the detection holes 151 may be linearly and evenly distributed. Thus, the position of the fabric roll 11 can be detected by the cooperation of the detection holes 151 and the position sensor 15.

[0089] In some examples, the position sensor 15 may be configured to detect the limit position of the fabric roll 11, and the detection holes 151 may be provided at the limit position of the fabric roll 11. In some examples, when the position sensor 15 detects the detection hole at the limit position, the length of the fabric roll 11 wound around one of the two reels 12 may be the circumferential perimeter of the cross-section of n reels 12. In some examples, n may be 1, 2, 3, 4 or 5. Thus, the limit position of the fabric roll 11 can be identified.

[0090] In some examples, when both ends of the fabric roll 11 are respectively fixed to two reels 12, when the position sensor 15 detects that the fabric roll 11 is in the extreme position, the fabric roll 11 stops its current motion state (that is, the fabric roll 11 switches from the current motion state to a stationary state or switches from the current motion direction to the opposite motion direction). Thereby, it is possible to reduce the damage to the fixed joints between the fabric roll 11 and the reels 12 due to excessive stretching, and it is possible to reduce the possibility that the fabric roll 11 is torn due to excessive internal tension.

[0091] In some examples, when one end of the fabric roll 11 is fixedly connected to the first reel 121 and the other end is movably connected to the second reel 122, when the position sensor 15 detects that the fabric roll 11 is in the extreme position, the fabric roll 11 stops its current motion state (that is, the fabric roll 11 switches from the motion state to a stationary state or switches from the current motion direction to the opposite motion direction). In some examples, when the fabric roll 11 is in the extreme position, the fabric roll 11 movably connected to the second reel 122 has a conservative length, and the length of the fabric roll 11 wound around the second reel 122 is the conservative length to prevent the fabric roll 11 from falling off the second reel 122. In some examples, the conservative length can be the circumferential perimeter of the cross-section of n reels 12. In some examples, n can be 1, 2, 3, 4, or 5. Thereby, it is possible to reduce the possibility that the movable connection between the fabric roll 11 and the reel 12 falls off the reel 12, and at the same time, it is possible to reduce the damage to the fixed joints between the fabric roll 11 and the reels 12 due to excessive stretching, and it is possible to reduce the possibility that the fabric roll 11 is torn due to excessive internal tension.

[0092] In some examples, the position sensor 15 can include an extreme position sensor 15 and an opening 111 alignment sensor. In some examples, the opening 111 alignment sensor can be configured to detect the position where the opening 111 is located to facilitate the alignment of the opening 111 with a predetermined window. Thereby, it is possible to identify the position of the opening 111, which is beneficial to the alignment of the position of the opening 111 with the window 14. In some examples, the extreme position sensor 15 can be configured to detect the extreme position of the fabric roll 11. Thereby, it is possible to identify the extreme position of the fabric roll 11.

[0093] In some examples, the isolation device 1 can include a fixing plate 16 (see Figure 4 ). In some examples, the window 14 can be located on the fixing plate 16. In some examples, the isolation device 1 can include two positioning shafts 17 (see Figure 4 ). In some examples, the two positioning shafts 17 can include a first positioning shaft 171 (see Figure 4 ) and a second positioning shaft 172 (see Figure 4)。In some examples, the first positioning shaft 171 may be located between the first reel 121 and the fixed plate 16, and the second positioning shaft 172 may be located between the second reel 122 and the fixed plate 16. In some examples, the rolled cloth 11 may be at least partially located between the positioning shaft 17 and the fixed plate 16. In this case, the position of the rolled cloth 11 can be restricted by the positioning shaft 17, which is beneficial to the rolled cloth 11 being attached to the fixed plate 16 in both the stationary and moving states. Additionally, the fixed plate 16 can also provide an additional isolation barrier outside the window 14 area, thereby enhancing the sealing effect of the rolled cloth 11 on the dispensing area or storage area, and further reducing the cross - contamination of pollutants between the dispensing area and the storage area.

[0094] In other examples, the first reel 121 may be located between the first positioning shaft 171 and the fixed plate 16. Thus, the position of the rolled cloth 11 can be restricted by the positioning shaft 17, which is beneficial to the rolled cloth 11 being attached to the fixed plate 16 and can enhance the sealing effect of the rolled cloth 11 on the plane adjacent to the rolled cloth 11. In some examples, the plane adjacent to the rolled cloth 11 may be the outer surface of the fixed plate 16, the outer surface of the dispensing area, or the outer surface of the storage area. It can be understood that the plane adjacent to the rolled cloth 11 may be the outer surface of the object sealed by the rolled cloth 11.

[0095] In some examples, the isolation device 1 may include a rolled - cloth slideway 18 (see Figure 2 ). In some examples, the rolled - cloth slideway 18 may be arranged along the length direction of the rolled cloth 11. Thus, it is beneficial for the rolled cloth 11 to maintain linear motion during movement, which is beneficial to improving the sealing effect of the rolled cloth 11 on the plane adjacent to the rolled cloth 11.

[0096] Figure 9 is a schematic diagram showing the cooperation between the rolled cloth 11 and the rolled - cloth slideway 18 involved in the examples of the present disclosure.

[0097] See Figure 9 , in some examples, the rolled - cloth slideway 18 may be configured to press the long side of the rolled cloth 11. In some examples, the rolled - cloth slideway 18 may include a first rolled - cloth slideway 181 and a second rolled - cloth slideway 182. The first rolled - cloth slideway 181 cooperates with the upper edge of the rolled cloth 11, and the second rolled - cloth slideway 182 cooperates with the lower edge of the rolled cloth 11. In some examples, the first rolled - cloth slideway 181 may include a first flange 1811 and a second flange 1812. In some examples, the second rolled - cloth slideway 182 may include a third flange 1821 and a fourth flange 1822. In some examples, the second flange 1812 may press or be adjacent to the upper edge 1111 of the opening, and the third flange 1821 may press or be adjacent to the lower edge 1112 of the opening. Thus, the sealing effect of the rolled cloth 11 on the plane adjacent to the rolled cloth 11 can be enhanced.

[0098] In some examples, the isolation device 1 may include an air curtain machine for blowing air to form an air curtain. In some examples, the main body of the air curtain machine may include multiple groups of fan sections. In some examples, based on the position where the opening 111 and the window 14 form a channel, the position of the air curtain can be adjusted by turning on the fan section corresponding to the position of the channel. In some examples, based on the width of the opening 111, the width of the air curtain can be adjusted by changing the number of turned-on fan sections. In some examples, the width of the air curtain is not less than the width of the channel formed by the opening 111 and the window 14. Thus, when the opening 111 and the window 14 form a connected channel, the air curtain can be used to reduce the cross-contamination between the medicine preparation area and the storage area.

[0099] In some examples, when the opening 111 and the window 14 are aligned to form a channel connecting the storage area and the medicine preparation area, the air curtain machine is turned on synchronously to facilitate the formation of an air curtain across the cross-section of the channel. Thus, when the opening 111 and the window 14 form a connected channel, the air curtain can be used to reduce the cross-contamination between the medicine preparation area and the storage area.

[0100] The automated medicine preparation system according to the second aspect of the present disclosure includes a medicine preparation area, a storage area for storing materials, a picking device, and the isolation device 1 according to the first aspect of the present disclosure. In this case, an automated medicine preparation system capable of reducing the cross-contamination of pollutants between the medicine preparation area and the storage area can be provided.

[0101] In some examples, the automated medicine preparation system may further include a programmable logic controller (PLC) to achieve the coordination or interaction between the picking device and the isolation device 1.

[0102] In some examples, the control process of the automated medicine preparation system for the picking device and the isolation device 1 may include: driving the cloth roll 11 to move so that the opening 111 is aligned with a predetermined window; the picking device transports the materials in the storage area to the medicine preparation area through the predetermined window; the driving mechanism 13 drives the cloth roll 11 to move to wind up the opening 111 on the reel 12.

[0103] In some examples, the driving mechanism 13 can wind up the cloth roll 11 on the reel 12 closest to the predetermined window. Thus, the high-power operation duration of the driving mechanism 13 can be reduced, and thereby the energy consumption of the driving mechanism 13 can be reduced.

[0104] In the present disclosure, an isolation device 1 and an automated medicine preparation system for reducing the cross-contamination of pollutants between the medicine preparation area and the storage area can be provided.

[0105] Although the present disclosure has been specifically described above in conjunction with the accompanying drawings and examples, it should be understood that the above 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 the essence and scope of the present disclosure, and these modifications and variations all fall within the scope of the present disclosure.
