In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist, nor in the protection scope required by the present application.

[0040] Please refer to Figures 1 to 5 The present application provides a kind of medicine weighing device.It can be understood that medicine weighing device can be applied as independent product equipment separately, also can be integrated with other functional devices to jointly constitute the processing production line of medicine.

[0041] It should be noted that the actual application of the present application is not limited to the weighing device, but for the convenience of understanding, in the following embodiments, the medicine weighing device is taken as an example to be described, which is vertically, longitudinally and transversely arranged in pairs and crosses. Among them, the included angle of the cross arrangement can be 90°, that is, perpendicular to each other. And in a specific application, the vertical direction can correspond to the direction of gravity, that is, the up and down direction; the horizontal direction and the longitudinal direction are two directions approximately perpendicular on the horizontal plane.

[0042] Therefore, the medicine weighing device comprises a seat body 100, a box changing module 200, a weighing module 300, a horizontal conveying module 400 and a vertical conveying module 500. The seat body 100 defines a first station 110 and a second station 120 arranged in sequence along the horizontal direction. The box changing module 200 comprises at least two rack bodies arranged vertically in the first station 110 and a first lifting mechanism 230 connected with the rack bodies. The two rack bodies have a vertical translation stroke and can be moved to the first station 110 in sequence. The two rack bodies are a first rack body 210 and a second rack body 220. The weighing module 300 comprises a carrier rack body 310 located in the second station 120 and a weighing sensor 320 connected with the carrier rack body 310. The horizontal conveying module 400 comprises a horizontal material moving piece having a horizontal translation stroke. The horizontal material moving piece is used to move the medicine box at the carrier rack body 310 to the first rack body 210 in the first station 110 and move the empty box at the second rack body 220 in the first station 110 to the carrier rack body 310. The vertical conveying module 500 comprises a vertical material moving piece having a vertical translation stroke. The vertical material moving piece is used to move the medicine box at the first rack body 210 out and move the empty box from outside to the second rack body 220.

[0043] In the technical scheme, at the second station 120, the medicine material is manually or mechanically placed into the empty box, the weighing sensor 320 weighs the empty box and the medicine material in real time, until the weight reaches the target, the empty box contains the required medicine material and constitutes the medicine box. The horizontal conveying module 400 runs forward, and the medicine box is transferred from the carrier rack body 310 to the first rack body 210 waiting in the first station 110. The first lifting mechanism 230 drives the second rack body 220 and another empty box arranged thereon to move to the first station 110. The horizontal conveying module 400 runs reversely, and the empty box is transferred from the first station 110 to the carrier rack body 310, waiting for the next medicine material to be loaded. The vertical conveying module 500 can move the medicine box from the first rack body 210 out and move the empty box from outside to the second rack body 220, so as to facilitate the next medicine weighing operation. The intelligent and automatic orderly operation of the modules helps to improve the efficiency and yield of the medicine weighing, boxing, moving out and empty box supplementing processes.

[0044] In the design, the seat body 100 can be a structure specially provided for the medicine weighing device or provided by a processing production line when the medicine weighing device is applied to the processing production line. Specifically, the seat body 100 can be but is not limited to a box body, a plate body, a block body, a rack body and the like. For example, the seat body 100 can be a box body 100a as shown in the figures. Figure 1As shown, the base 100 generally includes a flat plate extending laterally and longitudinally, and side plates extending vertically and connected to each side of the flat plate. The flat plate and the side plates together enclose a storage space. The flat plate defines a first workstation 110 by having a first through hole extending vertically, and a second workstation 120 by having a second through hole extending vertically. In this way, while the platform provides sufficient upward support for the box-changing module 200, the weighing module 300, etc., sufficient installation and movement space can be reserved for the box-changing module 200, the weighing module 300, etc. inside and outside the storage space, avoiding the box-changing module 200, the weighing module 300, etc. being set too high on the upper side of the flat plate.

[0045] The box-changing module 200 includes at least two frames. See attached for details. Figures 1 to 5 Taking two frames as an example, the two frames can be a first frame 210 and a second frame 220. The first frame 210 and the second frame 220 are arranged vertically at a distance from each other at the first workstation 110 of the base 100. Specifically, the first frame 210 can be located vertically above or below the second frame 220. For ease of understanding, the following example, as shown in the attached figure, will be used to illustrate the situation where the first frame 210 is located vertically below the second frame 220.

[0046] In its initial state, the first frame 210 can be moved directly to the first workstation 110 (i.e., its surface is basically flush with the first through hole), at which point the second frame 220 can be located vertically above the first frame 210. Alternatively, the second frame 220 can be moved directly to the first workstation 110, at which point the first frame 210 can be located vertically below the second frame 220. Of course, it is also possible that the first frame 210 and the second frame 220 are positioned on opposite vertical sides of the first workstation 110.

[0047] The first frame 210 and the second frame 220 are vertically spaced apart, specifically, for example, by being connected by a vertically extending connecting frame 250. The connecting frame 250 can be, for example, rod-shaped, and can be one or more. Specifically, the connecting frame 250 can be a fixed-length structural member, such that the distance between the first frame 210 and the second frame 220 is a fixed value and cannot be adjusted. Alternatively, the connecting frame 250 can be a vertically telescopic structural member, such that the distance between the first frame 210 and the second frame 220 is a range-adjustable value. In this case, the connecting frame 250 can be, for example, a combination of multiple sequentially adjustable telescopic joints, or a combination of, for example, a lead screw and nut, a gear and rack, etc., without limitation. When the distance between the first frame 210 and the second frame 220 is adjustable, it helps to flexibly set the space between the first frame 210 and the second frame 220, and helps to make the weighing device flexible for various sizes of empty boxes and medicine boxes.

[0048] Both the first frame 210 and the second frame 220 can be generally configured as a frame, that is, composed of multiple rods or plates connected sequentially along the horizontal and vertical directions. The frame-like configuration allows the first frame 210 and the second frame 220 to define an inner area, thereby enabling at least a portion of the horizontal conveying module 400 and / or the vertical conveying module 500 to be reasonably utilized within this inner area, which further contributes to a more compact structure.

[0049] The specific design of the first lifting mechanism 230 is not limited, and any power mechanism capable of driving each frame to have a vertical translational stroke is acceptable. For example, the first lifting mechanism 230 may include a driver such as a telescopic cylinder, or the first lifting mechanism 230 may be composed of a driver such as a telescopic cylinder and a motor, and a transmission assembly such as a gear set, a gear rack assembly, and a lead screw and nut assembly.

[0050] Specifically, such as Figures 1 to 5 As shown, the box-changing module 200 also includes a first mounting base 261 and a second mounting base 262. The first mounting base 261 is disposed within the storage space and is generally U-shaped, and is connected and fixed to the base body 100; the second mounting base 262 is disposed above the first mounting base 261 and is also generally U-shaped, and is connected and fixed to each frame. The first lifting mechanism 230 is disposed below the first mounting base 261, and the main body of the first lifting mechanism 230 (i.e., the part without translation output, such as the body of a telescopic cylinder) is connected and fixed to the first mounting base 261; the power part of the first lifting mechanism 230 (i.e., the part with translation output, such as the telescopic rod of a telescopic cylinder) is connected and fixed to the second mounting base 262. Furthermore, to provide stable lifting for each frame, one of the first mounting base 261 and the second mounting base 262 may have a vertically extending rod 240, and the other may have a guide hole, which is slidably connected to the vertical rod 240. The guide hole and the vertical rod 240 can be set as one or more in a group.

[0051] The carrier frame 310 in the weighing module 300 can also be provided in a frame shape and extend in the transverse and longitudinal directions to form a required size of a carrying area. The weighing sensor 320 can be a sensor capable of sensing pressure, such as a weight sensor, a pressure sensor, etc. At this time, the weighing module 300 can further include a support frame 330 provided in the accommodation space and fixedly connected with the seat body 100. The carrier frame 310 is arranged above the support frame 330. Specifically, the weighing sensor 320 can be arranged between the carrier frame 310 and the support frame 330. Of course, in other embodiments, the weighing sensor 320 can specifically be a sensor capable of sensing tension. At this time, the weighing sensor 320 can be arranged above the carrier frame 310, and the carrier frame 310 and the empty box and the medicine box placed thereon are all suspended below the weighing sensor 320.

[0052] In actual application, the weighing sensor 320 can be provided as one or several. When the weighing sensor 320 is provided as a plurality of sensors, the connection points of the weighing sensors 320 and the carrier frame 310 can be uniformly and dispersedly arranged in the transverse and longitudinal directions, for example, uniformly and spaced apart along the circumferential direction of the carrier frame 310.

[0053] It can be understood that when the empty box is arranged on the carrier frame 310, the empty box is generally open, and the operator can manually or automatically based on a mechanical mechanism load the medicinal materials into the empty box. The medicinal materials loaded in the same empty box can be specifically of the same type or multiple types.

[0054] The transverse material moving member in the transverse conveying module 400 is mainly used to realize the reciprocating movement of the material (specifically, the empty box and the medicine box) between the first station 110 and the second station 120. Specifically, the transverse material moving member can be provided as one and is sufficient to connect the first station 110 and the second station 120. Alternatively, the transverse material moving member can be provided as two at the first station 110 and the second station 120 respectively and collectively connect the first station 110 and the second station 120. At this time, the two transverse material moving members can be of the same structure or different structures.

[0055] Please refer to Figures 1 to 5In an embodiment, the lateral transferring member includes a plurality of rollers 411 arranged side by side in the frame inner region of the frame body in sequence along the lateral direction, and a first conveying belt 421 arranged on the object supporting frame body 310, each roller 411 extending along the longitudinal direction in an elongated manner. The lateral conveying module 400 further includes two first pulleys 422 arranged at intervals along the longitudinal direction, a first rotary driver drivingly connected with at least one of the first pulleys 422, and a fourth rotary driver drivingly connected with at least one of the rollers 411 to drive the rollers 411 to rotate in the forward and reverse directions about the longitudinal axis, respectively.

[0056] Specifically, the lateral conveying module 400 can further include two connecting plates 412 arranged at intervals along the longitudinal direction. Each roller 411 is rotatably mounted about its own axis between the two connecting plates 412. In a specific application, the fourth rotary driver can be drivingly connected with one roller 411. At this time, the remaining rollers 411 can be drivingly connected with each other through rolling fit. Alternatively, when each roller 411 is kept spaced apart in the radial direction, the lateral conveying module 400 can further include a plurality of connecting belts 413, each two adjacent rollers 411 being drivingly connected with each other through a connecting belt 413. When each roller 411 is rotated toward the second station 120 under the driving of the fourth rotary driver, the object at the first station 110 can be transferred to the second station 120; conversely, when each roller 411 is rotated away from the second station 120 under the driving of the fourth rotary driver, the object at the second station 120 can be transferred to the first station 110.

[0057] When the frame body is arranged in a frame shape, each roller shaft 411, connecting plate 412 and connecting belt 413 and the like can be connected into an integral whole and arranged at the inner region of the frame of the frame body. In actual application, when the first frame body 210 is moved to the first station 110, the medicine box at the second station 120 needs to be transferred to the first frame body 210 by means of the horizontal conveying module 400; conversely, when the second frame body 220 is moved to the first station 110, the empty box of the second frame body 220 needs to be transferred to the second station 120 by means of the horizontal conveying module 400. Therefore, as to the horizontal material moving piece arranged as the roller shaft 411, two horizontal conveying modules 400 can be arranged corresponding to the two frame bodies, and move vertically along with the corresponding frame bodies. Alternatively, the horizontal conveying module 400 can be arranged at the first station 110, and arranged independently of each frame body. At this time, for example, the horizontal material moving piece is connected with the seat body 100 and located at the first station 110. Since the frame bodies are all arranged in a frame shape, the arrangement of the horizontal conveying module 400 does not interfere with the lifting movement of the two frame bodies. When the first frame body 210 is moved to the first station 110, the horizontal conveying module 400 is applied to the horizontal transfer of the material of the first frame body 210; conversely, when the second frame body 220 is moved to the first station 110, the horizontal conveying module 400 is applied to the horizontal transfer of the material of the second frame body 220.

[0058] The first conveying belt 421 extends horizontally. The first rotary driver is drivingly connected with at least one first pulley 422, drives the first pulley 422 to rotate, and then drives the first conveying belt 421 to rotate in a forward direction and a reverse direction in the horizontal direction. The forward rotation can mean rotation from the second station 120 to the first station 110, and the reverse rotation can mean rotation from the first station 110 to the second station 120. When the first conveying belt 421 rotates in the forward direction, it can drive the material at the second station 120 to be transferred to the first station 110; conversely, when the first conveying belt 421 rotates in the reverse direction, it can drive the material at the first station 110 to be transferred to the second station 120.

[0059] It should be noted that the first conveying belt 421 can be arranged as one or at least two. When the first conveying belt 421 is arranged as one, its width and arrangement position can be arranged to be sufficient to support the empty box or the medicine box. When the first conveying belt 421 is arranged as at least two, each first conveying belt 421 can be arranged in sequence in the longitudinal direction, and each first conveying belt 421 can be arranged synchronously. For example, as shown in FIG. 6, the first conveying belt 421 can be arranged as two, and the two first conveying belts 421 can be arranged in sequence in the longitudinal direction. Figure 2 and Figure 5As shown, the first conveyor belt 421 can be specifically provided as two, and the two first conveyor belts 421 are arranged on the two longitudinal sides of the carrier body 310. At this time, the first pulley 422 has an axis body which can be manifested as extending along the longitudinal direction, and the same axis body can be provided for the two first conveyor belts 421 to be arranged around. In this way, the same first rotary driver and the two first pulleys 422 can be used to realize the synchronous driving of the two first conveyor belts 421.

[0060] In addition, in an embodiment, the longitudinal material moving member includes a second conveyor belt 511 extending along the longitudinal direction; the longitudinal conveying module 500 further includes two second pulleys 512 arranged along the longitudinal direction and a second rotary driver drivingly connected with at least one second pulley 512, and the second conveyor belt 511 is arranged in a closed loop around the outside of the two second pulleys 512. The second rotary driver drives the second pulley 512 to rotate, and then the second conveyor belt 511 is driven by the second pulley 512 to rotate in the forward direction and the reverse direction along the longitudinal direction. The forward rotation can refer to the rotation from the carrier body to the outside, and the reverse rotation can refer to the rotation from the outside to the carrier body. When the forward rotation, the second conveyor belt 511 can drive the material on the carrier body to move outward; on the contrary, when the reverse rotation, the second conveyor belt 511 can drive the material outside to move into the carrier body.

[0061] Next, the longitudinal conveying module 500 is generally one-to-one corresponding to each carrier body in the same cartridge changing module 200. That is, each carrier body is independently provided with a longitudinal conveying module 500. For example, as shown in FIG. 2, the longitudinal conveying module 500 is arranged on the first carrier body 210 and the second carrier body 220. Figures 1 to 5 For example, the same cartridge changing module 200 is provided with two carrier bodies, and the longitudinal conveying module 500 is one-to-one corresponding to the two carrier bodies and is provided with two longitudinal conveying modules 500 which are vertically translated with the corresponding carrier bodies. It should be noted that the longitudinal translation directions of the two longitudinal material moving members on the two carrier bodies can be the same, that is, the moving-out direction of the cartridge on the first carrier body 210 and the moving-in direction of the empty cartridge on the second carrier body 220 are the same. Alternatively, the longitudinal translation directions of the two longitudinal material moving members on the two carrier bodies are opposite. That is, the moving-out direction of the cartridge on the first carrier body 210 and the moving-in direction of the empty cartridge on the second carrier body 220 are opposite.

[0062] Similarly, the second conveyor belt 511 can be provided as one or at least two. When the second conveyor belt 511 is provided as one, its width and arrangement position can be arranged to be sufficient to support the empty cartridge or the cartridge. When the second conveyor belt 511 is provided as at least two, each second conveyor belt 511 can be arranged in sequence along the transverse direction, and each second conveyor belt 511 can be synchronously arranged. For example, as shown in FIG. 2, the second conveyor belt 511 is provided as two, and the two second conveyor belts 511 are arranged on the two transverse sides of the carrier body 310. Figure 3As shown, the second conveyor belt 511 can be specifically provided as two, and the two second conveyor belts 511 are provided at the lateral sides of the frame body. At this time, the second pulley 512 has an axis body which can extend in the lateral direction, and the same axis body can be provided for the two second conveyor belts 511 to be arranged around. In this way, the same second rotary driver and the two second pulleys 512 can be used to synchronously drive the two second conveyor belts 511.

[0063] When the frame body is provided as a frame, each roller shaft 411 can be arranged in the inner region of the frame as described above. At this time, further, taking the longitudinal conveying module 500 as an example, when the second conveyor belt 511 is provided as one, the second conveyor belt 511 can be arranged at any position in the inner region of the frame, for example, arranged beside each roller shaft 411, or interposed between each roller shaft 411, and can be specifically arranged in the middle of the inner region of the frame. When the second conveyor belt 511 is provided as at least two, a group of second conveyor belts 511 can be arranged at the lateral sides of each roller shaft 411, respectively.

[0064] In view of the above, since the lateral conveying module 400 and the longitudinal conveying module 500 need to be operated simultaneously or at different times in the frame body at the first station 110. Therefore, in order to reduce the mutual interference of the operation of the lateral conveying module 400 and the longitudinal conveying module 500, in an embodiment, at least one of the lateral moving member and the longitudinal moving member has a relative vertical translation stroke relative to the other. The dispensing device further comprises a second lifting mechanism connected to the lateral moving member and the longitudinal moving member, respectively, and the second lifting mechanism is used to drive the longitudinal moving member to be lower than the lateral moving member when the lateral conveying module 400 is started to operate, and drive the lateral moving member to be lower than the longitudinal moving member when the longitudinal conveying module 500 is started to operate.

[0065] It should be noted that the above mainly refers to the lateral moving member and the longitudinal moving member arranged in the frame body, for example, the above-mentioned roller shaft 411 and the second conveyor belt 511. The roller shaft 411 is integrated with the connecting plate 412 and the connecting belt 413, and the integrated body can be moved upward or downward relative to the second conveyor belt 511. When the lateral conveying module 400 needs to be operated, the second lifting mechanism can drive the roller shaft 411 to move upward and / or the second conveyor belt 511 to move downward, so that the roller shaft 411 is substantially flush with the first conveyor belt 421, and the second conveyor belt 511 is lower than the first conveyor belt 421. Conversely, when the longitudinal conveying module 500 needs to be operated, the second lifting mechanism can drive the roller shaft 411 to move downward and / or the second conveyor belt 511 to move upward, so that the roller shaft 411 is not in contact with the empty box or the medicine box, and only the second conveyor belt 511 is in contact with the empty box or the medicine box, to achieve the purpose of longitudinal moving.

[0066] In view of the above, in a further aspect, the dosing device further comprises a first stopper 610 and / or a second stopper 620.

[0067] The first stopper 610 is disposed beside the first station 110 and downstream of the lateral movement of the lateral material moving member from the second station 120 to the first station 110. In this way, the medicine box can be stopped, positioned and located when the lateral material moving member moves the medicine box from the carrier rack body 310 to the first rack body 210. Of course, in other embodiments, the first stopper 610 can also be disposed beside the second station 120 and downstream of the lateral movement of the lateral material moving member from the first station 110 to the second station 120. In this way, the empty medicine box can be stopped, positioned and located when the lateral material moving member moves the empty medicine box from the second rack body 220 to the carrier rack body 310.

[0068] The first stopper 610 can be fixed relative to the seat body 100, i.e. directly fixedly connected to the seat body 100. Alternatively, the first stopper 610 can be movably mounted on the seat body 100 and have a telescopic movement stroke in the vertical, lateral and / or longitudinal direction. In this way, the machine can have an adjustment degree of freedom in the vertical, lateral and / or longitudinal direction, so that the machine is more suitable for different specifications and different running modes of the processing production line.

[0069] The second stopper 620 is disposed beside the first station 110 and downstream of the longitudinal movement of the longitudinal material moving member. In this way, the medicine box can be stopped, positioned and located when the longitudinal material moving member moves the medicine box out or moves the empty medicine box in.

[0070] The second stopper 620 can be fixed relative to the seat body 100, i.e. directly fixedly connected to the seat body 100. Alternatively, the second stopper 620 can be movably mounted on the seat body 100 and have a telescopic movement stroke in the vertical, lateral and / or longitudinal direction. In this way, the machine can have an adjustment degree of freedom in the vertical, lateral and / or longitudinal direction, so that the machine is more suitable for different specifications and different running modes of the processing production line.

[0071] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation or direct / indirect application in other related technical fields based on the inventive concept of the present application and the contents of the present application specification and drawings are included in the patent protection scope of the present application.
