[0048] Another object of the present invention is to provide an automated logistics transmission method applied to a liquid dispensing center, which has the effect of high-automation transmission.

[0049] The above technical object of the present invention is achieved by the following technical solutions: A logistics system applied to a liquid dispensing center includes the following steps:

[0050] S1, the transmission chain at the import section: Driven and controlled by the transmission wheels at the import section position, the transmission chain moves into the import section area of the transmission chain at a certain beat duration. When it stops, the inner section of the transmission chain that can carry the injection vials aligns with the output mechanism of the medicine discharging machine, and the output mechanism of the medicine discharging machine sends the injection vials into the transmission chain in the import section, completing the import and loading of the medicine.

[0051] S2, the transmission chain at the export section: Driven and controlled by the transmission wheels at the export section position, the transmission chain moves into the export section at a certain beat duration. When it stops, the inner section of the transmission chain carrying the injection vials aligns with the input mechanism of the liquid dispensing machine. At this time, the first ejector rod on the export section pushes the vial into the input mechanism of the liquid dispensing machine located above, completing the transmission task of the vial from the medicine discharging machine to the liquid dispensing machine. If there are more than one export sections, a part of the transmission chain loaded with medicine does not stop and unload the vials at the previous export section, but directly passes through the previous export section and enters the subsequent export section, so that the injection vials in the transmission chain can be distributed to the input mechanisms of the liquid dispensing machines corresponding to each export section.

[0052] S3, the secondary transmission chain at the import section: Pulled by the sprockets for the import of the secondary transmission chain, the secondary transmission chain moves into the import section area; when it stops, the import section of the secondary transmission chain aligns with the export section of the transmission chain. At this time, the injection vials in the export section of the transmission chain enter the inner section of the import section of the secondary transmission chain, completing the import and loading of the medicine.

[0053] S4, the secondary transmission chain at the export section: Pulled by the sprockets at the export section of the secondary transmission chain, the secondary transmission chain moves into the export section area; when it stops, the inner section of the secondary transmission chain carrying the vials aligns with the input mechanism of the liquid dispensing machine. At this time, the second ejector rod on the export section of the secondary transmission chain inputs the vial into the input mechanism of the liquid dispensing machine, completing the transmission task of the vial from the medicine discharging machine to the liquid dispensing machine.

[0054] S5, between the export sections of the transmission chain and the secondary transmission chain, and between the export section and the import section: After the transmission chain and the secondary transmission chain are pushed out from any straight section, they move forward under the combined action of the pushing of the rear sprockets and the pulling of the front sprockets; if the pulling movement amount of the front sprockets is less than the pushing movement amount of the rear sprockets, the transmission chain and the secondary transmission chain will bend freely; if the bending amount reaches the upper limit of the predetermined value, the rear sprockets will pause pushing and wait for the front sprockets to increase the pulling movement amount; if the bending amount reaches the lower limit of the predetermined value, the sprockets at the front export section position will pause pulling and wait for the rear sprockets to increase the pushing movement amount.

[0055] In summary, the present invention has the following beneficial effects:

[0056] 1. The transport of injection bottles between the dispensing machine and the liquid dispensing machine is achieved by adopting a highly automated and highly continuous transmission chain. At the same time, a transmission chain that combines tension and relaxation is adopted to achieve highly continuous transport of injection bottles.

[0057] 2. By using multiple secondary conveyor chains to connect to the transmission chain, rapid and continuous extraction of injection vials in the transmission chain is achieved, thereby achieving efficient supply of injection vials in the dispensing machine and improving dispensing efficiency;

[0058] 3. It adopts two modes of transmission: walking from above and below the drug discharging machine and liquid dispensing machine, which is suitable for different working environments, meets different usage requirements and improves adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0071] The present invention will be further described in detail below with reference to the accompanying drawings.

[0072] Embodiment 1:

[0073] As Figure 1 shown, an automated logistics system applied to a liquid dispensing center includes a medicine discharging machine 1, a liquid dispensing machine 2, a transmission chain 3, a first platform 4 and a transmission wheel 5.

[0074] As Figure 1 , Figure 2 shown, the medicine discharging machine 1 is internally provided with an output mechanism 11. The output mechanism 11 includes a delivery pipe 12, a control valve 13 and a control member 14. The delivery pipe 12 is vertically located inside the medicine discharging machine 1. The control valve 13 is located at the lower end of the delivery pipe 12 and is used to control the opening and closing of the delivery pipe 12. The control member 14 is a slider and a guide rail. The slider is connected to the delivery pipe 12 and is used to control the displacement of the delivery pipe 12 in the horizontal direction or in a two-dimensional plane. The liquid dispensing machine 2 is internally provided with an input mechanism. The input mechanism can be a structure such as a delivery pipe, a manipulator or a pneumatic gripper, etc., for inputting injection vials.

[0075] As Figure 1 , Figure 2 shown, the transmission chain 3 is at least one closed-loop chain. The transmission chain 3 is composed of inner links and outer links. The inner link of the transmission chain 3 is a hollow tube with an open upper end for storing injection vials, which is used to dock with the output mechanism 11 and realize the storage of injection vials.

[0076] As Figure 1 shown, the first platform 4 is horizontally arranged and extends to all the running ranges of the transmission chain 3. The first platform 4 includes the internal plane of the medicine discharging machine 1, the internal plane of the liquid dispensing machine 2 and the external plane through which the transmission chain 3 passes between the medicine discharging machine 1 and the liquid dispensing machine 2, for supporting the transmission chain 3.

[0077] As Figure 1 shown, the transmission wheels 5 are arranged in pairs on the first platform 4 for driving and guiding the operation of the transmission chain 3. The transmission chain 3 includes at least one injection vial inlet section and at least one injection vial outlet section. Transmission wheels 5 are arranged at both ends of the inlet section and the outlet section of the transmission chain 3, and the inlet section and the outlet section of the transmission chain 3 are tightened into a straight line by the transmission wheels 5 at both ends. Other parts of the transmission chain 3 are in a relaxed state, so that the inlet section and the outlet section of each transmission chain 3 can operate out of sync with each other.

[0078] As Figure 1 , Figure 3 shown, the upper end of the inner section of the inlet section of the transmission chain 3 is docked with the output mechanism 11 of the medicine discharging machine 1, and the lower end abuts against the upper end face of the first platform 4, storing the injection vials and carrying the injection vials for transmission. The upper end of the inner section of the outlet section of the transmission chain 3 is docked with the input mechanism of the liquid dispensing machine 2, and the injection vials are transmitted from bottom to top.

[0079] As Figure 1 , Figure 3 shown, the outlet section of the transmission chain 3 further includes a first ejector rod 31 and a first driving source 32. The first ejector rod 31 moves vertically from bottom to top and is used to pass through the inner section of the outlet section of the transmission chain 3. The first driving source 32 is a cylinder or an electric cylinder for controlling the vertical reciprocating motion of the first ejector rod 31.

[0080] When working, the transmission chain 3 is located below the medicine discharging machine 1 and the liquid dispensing machine 2. When it is necessary to transmit the injection vials, the single injection vial output from the medicine discharging machine 1 is conveyed into the conveying pipe 12. Subsequently, under the driving control of the transmission wheel 5 at the inlet section position, the transmission chain 3 moves into the inlet section area at a certain time-beat. When it stops, the control valve 13 below the conveying pipe 12 is opened, and then the injection vial in the conveying pipe 12 drops into the inner section of the transmission chain 3 to complete the import and loading of the medicine.

[0081] Subsequently, under the driving control of the transmission wheel 5 at the inlet section position, the transmission chain 3 is moved out of the medicine discharging machine 1 and into the external channel from the medicine discharging machine 1 to the liquid dispensing machine 2. Pushed by the transmission wheel 5 at the rear inlet section position and pulled by the transmission wheel 5 at the front outlet section position, the transmission chain 3 moves towards the outlet section direction.

[0082] Due to the different rotational speeds of the transmission wheels 5, if the pulling movement amount of the transmission chain 3 is less than the pushing amount of the transmission chain 3, the transmission chain 3 will bend freely. If the bending amount reaches the upper limit of the predetermined value, the transmission wheel 5 at the rear inlet section position will pause pushing. If the bending amount reaches the lower limit of the predetermined value, the transmission wheel 5 at the front outlet section position will pause pulling, so as to control the transmission chain 3 between the inlet section, the outlet section and the inlet section and the outlet section to move at different speeds respectively, realizing the transmission of the injection vials.

[0083] Subsequently, driven and controlled by the transmission wheel 5 at the position of the export section, the transmission chain 3 moves into the export section at a rhythm for a certain period of time. When it stops, the inner section of the transmission chain 3 carrying the injection vials aligns with the input mechanism of the liquid dispensing machine 2. At this time, the first ejector rod 31 moves upward and ejects the injection vial into the input mechanism of the liquid dispensing machine 2 located above, completing the transmission task of the vial from the medicine discharging machine 1 to the liquid dispensing machine 2.

[0084] During the output process, if there is more than one export section, a part of the transmission chain 3 loaded with drugs does not stop unloading the vials at the previous export section, but directly passes through the previous export section and enters the subsequent export section, so that the injection vials in the transmission chain 3 can be distributed to the input mechanisms of the liquid dispensing machines 2 corresponding to each export section.

[0085] Embodiment 2:

[0086] As Figure 4 、 Figure 5 shown, an automated logistics system applied to a liquid dispensing center, which is different from Embodiment 1 in that: it further includes at least one secondary transmission mechanism 6, and the secondary transmission mechanism 6 is located between the transmission chain 3 and the input mechanism of the liquid dispensing machine 2 for storing the injection vials in the transmission chain 3 and performing secondary transmission of the injection vials.

[0087] As Figure 4 、 Figure 5 shown, the secondary transmission mechanism 6 includes a secondary transmission chain 61, a second platform 62 and secondary transmission wheels 63. The secondary transmission chain 61 is at least one closed-loop chain, which is composed of inner sections and outer sections. The inner section of the secondary transmission chain 61 is a hollow tube with an open upper end for storing injection vials, and is located between the transmission chain 3 and the liquid dispensing machine 2.

[0088] As Figure 4 、 Figure 5 shown, the second platform 62 is arranged in the liquid dispensing machine 2 and supports the secondary transmission chain 61, and extends to all operating ranges of the secondary transmission chain 61. The secondary transmission wheels 63 are fixedly arranged in pairs on the second platform 62 for driving and guiding the operation of the secondary transmission chain 61.

[0089] As Figure 4 、 Figure 5 shown, the secondary transmission chain 61 includes at least one injection vial import section and at least one injection vial export section. The import section of the secondary transmission chain 61 is docked with the export section of the transmission chain 3, and the export section of the secondary transmission chain 61 is docked with the input mechanism of the liquid dispensing machine 2.

[0090] As Figure 4 、 Figure 5As shown, second-stage transfer wheels 63 are provided at both ends of the inlet section and the outlet section of the second-stage transfer chain 61. The inlet section and the outlet section of the second-stage transfer chain 61 are tightened into a straight line by the second-stage transfer wheels 63 at both ends. The other parts of the second-stage transfer chain 61 are in a slack state, enabling the inlet section and the outlet section of each second-stage transfer chain 61 to operate out of sync with each other.

[0091] As Figure 5 , Figure 6 shown, a first channel 64 is provided through the second platform 62. The first channel 64 allows the first ejector rod 31 and the injection vial to pass through. The upper end of the first channel 64 is docked with the inner section of the inlet section of the second-stage transfer chain 61, and the lower end is docked with the inner section of the outlet section of the transfer chain 3. A first one-way valve 65 for controlling the opening and closing of the first channel 64 is provided on the second platform 62.

[0092] As Figure 5 shown, the outlet section of the second-stage transfer chain 61 includes a second ejector rod 66 and a second drive source 67. The second ejector rod 66 moves vertically from bottom to top and is used to pass through the inner section of the outlet section of the second-stage transfer chain 61 and dock with the input mechanism of the liquid dispensing machine 2. The second drive source 67 is a cylinder or an electric cylinder for controlling the vertical reciprocating movement of the second ejector rod 66.

[0093] When transporting the injection vial, each second-stage transfer chain 61 corresponds to a manipulator in the liquid dispensing machine 2. Therefore, when the injection vial is transported to the position of the outlet section of the transfer chain 3, the injection vial is exactly at the position of the inlet section of the second-stage transfer chain 61. At this time, under the ejection action of the first ejector rod 31, the first one-way valve 65 is opened, enabling the injection vial to pass through the first channel 64 and enter the inner section of the second-stage transfer chain 61, and the first one-way valve 65 is used to block it to prevent the injection vial from falling.

[0094] The working mode and working principle of the second-stage transfer chain 61 are the same as those of the transfer chain 3, realizing the transportation of the injection vial, which will not be elaborated here. Until the injection vial is transported to the position of the outlet section of the second-stage transfer chain 61, the second ejector rod 66 moves vertically, causing the second ejector rod 66 to pass through the inner section of the outlet section of the second-stage transfer chain 61 and eject the injection vial to realize the transportation of the injection vial.

[0095] As Figure 5 , Figure 6 shown, the first one-way valve 65 includes a first rotating shaft 651 and a first one-way valve plate 652. The first rotating shaft 651 is horizontally arranged at one end of the first channel 64, and the first one-way valve plate 652 is rotatably connected to the first rotating shaft 651.

[0096] As Figure 5 , Figure 6As shown, the first one-way valve plate 652 can rotate freely within the range from the horizontal position to the upright position. When in the horizontal position, it supports the injection vial and prevents the injection vial from sliding downwards. When in the upright position, it allows the injection vial to move upwards from below and pass through the first channel 64.

[0097] As Figure 5 , Figure 6 shown, at the lower end of the inner link of the secondary conveyor chain 61, a first notch 653 is formed, and the first notch 653 allows the first one-way valve plate 652 to pass through unobstructed when it rotates.

[0098] As Figure 5 , Figure 6 shown, on the surface of the second platform 62, first grooves 654 are formed, and the first one-way valve plate 652 is embedded in the first grooves 654. At the same time, when the first one-way valve plate 652 is in the horizontal position, its upper end surface is flush with the surface of the second platform 62, so that the injection vial can smoothly move through the first channel 64.

[0099] When the injection vial is ejected, the injection vial controls the first one-way valve plate 652 to automatically flip upwards, and enables the first one-way valve plate 652 to pass through the first notch 653 at the lower end of the secondary conveyor chain 61 unobstructed, so that the transmission of the secondary conveyor chain 61 and the flipping of the first one-way valve plate 652 do not interfere with each other.

[0100] Until the injection vial completely enters the inner link of the secondary conveyor chain 61, the first one-way valve plate 652 automatically flips downwards and abuts against the outer wall of the first ejector rod 31. Subsequently, until the first ejector rod 31 completely exits the inner link of the secondary conveyor chain 61, the first one-way valve plate 652 continues to flip downwards and gradually embeds into the first groove 654 and is flush with the surface of the second platform 62. At the same time, the first one-way valve plate 652 supports the injection vial, enabling the injection vial to pass smoothly and realizing the stable transmission of the injection vial.

[0101] Embodiment 3:

[0102] As Figure 7 , Figure 8 , Figure 9 shown, an automated logistics system applied to a liquid preparation center, which is different from that in Embodiment 1 in that: on the inner plane of the first platform 4 located inside the medicine dispensing machine 1, a second channel 41 is formed, and on the inner plane of the liquid preparation machine 2, a third channel 42 is formed. On the first platform 4, a second one-way valve 43 and a third bottom valve 44 for respectively controlling the opening and closing of the second channel 41 and the third channel 42 are provided.

[0103] As Figure 7 , Figure 8As shown, the upper end of the second channel 41 is docked with the inner section of the inlet section of the transfer chain 3, and the lower end is docked with the output mechanism 11 of the medicine discharging machine 1. The upper end of the third channel 42 is docked with the inner section of the outlet section of the transfer chain 3, and the lower end is docked with the input mechanism of the liquid dispensing machine 2.

[0104] As Figure 7 , Figure 8 shown, the output mechanism 11 of the medicine discharging machine 1 includes an output pipe 15 and an output rod 16. The output pipe 15 is located below the first platform 4 for outputting injection vials, and is docked with the lower end of the second channel 41. The output rod 16 vertically penetrates the output pipe 15, and is used to sequentially penetrate the second channel 41 and the inner section of the inlet section of the transfer chain 3, and output the injection vials stored in the output pipe 15 into the inner section of the transfer chain 3.

[0105] When working, the transfer chain 3 is located above the medicine discharging machine 1 and the liquid dispensing machine 2, and when it is necessary to transfer the injection vials, the single injection vial output from the medicine discharging machine 1 is conveyed into the output pipe 15, and then the output rod 16 pushes the injection vial upward, so that the injection vial passes through the second one-way valve 43 and the second channel 41 and then enters the inner section of the inlet section of the transfer chain 3 to complete the import and loading of the medicine.

[0106] When the transfer chain 3 moves to its outlet section position, the injection vial is moved to the position of the third channel 42. At this time, the third bottom valve 44 opens, and the injection vial falls naturally and is docked with the input mechanism of the liquid dispensing machine 2, thereby realizing the transfer of the injection vial.

[0107] As Figure 8 shown, each second one-way valve 43 includes a second rotating shaft 431 and a second one-way valve plate 43. The second rotating shaft 431 is horizontally arranged at one end of the second channel 41, and the second one-way valve plate 43 is rotatably connected to the second rotating shaft 431.

[0108] As Figure 8 shown, the second one-way valve plate 43 can freely rotate within the range from the horizontal position to the upward erected position. When in the horizontal position, it supports the injection vial and prevents the injection vial from sliding down. When in the erected position, it allows the injection vial to move upward from below and pass through the second channel 41.

[0109] As Figure 8 shown, a second notch 433 is opened at the lower end of the inner section of the transfer chain 3 for the second one-way valve plate 43 to pass through without hindrance when rotating.

[0110] As Figure 8 shown, second grooves 434 are opened on the surface of the second platform 62, and the second one-way valve plate 43 is embedded in the second grooves 434. When the second one-way valve plate 43 is in the horizontal position, its upper end face is flush with the surface of the first platform 4, so that the injection vial can smoothly move through the second channel 41.

[0111] When the injection vial is ejected, the injection vial controls the second one-way valve plate 43 to automatically flip upward, and enables the second one-way valve plate 43 to pass through the second notch 433 at the lower end of the transmission chain 3 without obstruction, so that the transmission of the transmission chain 3 and the flipping of the second one-way valve plate 43 do not interfere with each other.

[0112] Until the injection vial completely enters the inner section of the transmission chain 3, the second one-way valve plate 43 automatically flips downward and abuts against the outer wall of the output rod 16. Subsequently, until the second ejector rod 66 completely exits the inner section of the transmission chain 3, the second one-way valve plate 43 continues to flip downward and gradually embeds into the second groove 434 and is flush with the surface of the first platform 4. At the same time, the second one-way valve plate 43 supports the injection vial, enabling the injection vial to pass smoothly and realizing the stable transmission of the injection vial.

[0113] Embodiment 4:

[0114] As Figure 10 、 Figure 11 shown, an automated logistics system applied to a liquid dispensing center, which is different from Embodiment 1 in that: the lower end of the third channel 42 is docked with the inner tube of the inlet section of the secondary conveyor chain 61, and a fourth channel 68 is provided on the second platform 62. The upper end of the fourth channel 68 is docked with the inner tube of the outlet section of the secondary conveyor chain 61, and the lower end is docked with the input mechanism of the liquid dispenser 2. A fourth bottom valve 69 for controlling the opening and closing of the fourth channel 68 is provided on the second platform 62.

[0115] When transporting the injection vial, each secondary conveyor chain 61 corresponds to a manipulator in the liquid dispenser 2. Therefore, when the injection vial is transported to the outlet section position of the transmission chain 3, the injection vial is exactly located at the inlet section position of the secondary conveyor chain 61. At this time, the injection vial freely falls along the third channel 42 and enters the inner section of the lower secondary conveyor chain 61.

[0116] The working mode and working principle of the secondary conveyor chain 61 are the same as those of the transmission chain 3, realizing the transportation of the injection vial, which will not be elaborated here. Until the injection vial is transported to the outlet section position of the secondary conveyor chain 61, the fourth bottom valve 69 opens, enabling the injection vial to automatically fall into the input mechanism of the liquid dispenser 2, thereby realizing the transportation of the injection vial.

[0117] Embodiment 5:

[0118] An automated logistics transmission method applied to a liquid dispensing center includes the following steps:

[0119] S1. In the import section of the transfer chain 3: Driven and controlled by the transfer wheel 5 at the import section position, the transfer chain 3 moves into the import section area of the transfer chain 3 at a rhythm with a certain time duration. When it stops, the inner section of the transfer chain 3 that can carry the injection vials aligns with the output mechanism 11 of the medicine discharging machine 1. The output mechanism 11 of the medicine discharging machine 1 sends the injection vials into the transfer chain 3 in the import section to complete the import and loading of the medicine.

[0120] S2. In the export section of the transfer chain 3: Driven and controlled by the transfer wheel 5 at the export section position, the transfer chain 3 moves into the export section at a rhythm with a certain time duration. When it stops, the inner section of the transfer chain 3 that carries the injection vials aligns with the input mechanism of the liquid dispensing machine 2. At this time, the first ejector rod 31 on the export section pushes the vial into the input mechanism of the liquid dispensing machine 2 located above to complete the transfer task of the vial from the medicine discharging machine 1 to the liquid dispensing machine 2. If there are more than one export sections, a part of the transfer chain 3 loaded with medicine does not stop and unload the vials at the previous export section, but directly passes through the previous export section and enters the subsequent export section, so that the injection vials in the transfer chain 3 can be distributed to the input mechanisms of the liquid dispensing machines 2 corresponding to each export section.

[0121] S3. In the import section of the secondary transfer chain 61: Driven by the sprocket at the import of the secondary transfer chain 61, the secondary transfer chain 61 moves into the import section area. When it stops, the import section of the secondary transfer chain 61 aligns with the export section of the transfer chain 3. At this time, the injection vials in the export section of the transfer chain 3 enter the inner section of the import section of the secondary transfer chain 61 to complete the import and loading of the medicine.

[0122] S3. In the export section of the secondary transfer chain 61: Driven by the sprocket at the export section of the secondary transfer chain 61, the secondary transfer chain 61 moves into the export section area. When it stops, the inner section of the secondary transfer chain 61 that carries the vials aligns with the input mechanism of the liquid dispensing machine 2. At this time, the second ejector rod 66 on the export section of the secondary transfer chain 61 inputs the vial into the input mechanism of the liquid dispensing machine 2 to complete the transfer task of the vial from the medicine discharging machine 1 to the liquid dispensing machine 2.

[0123] S4. Between the export sections of the transfer chain 3 and the secondary transfer chain 61, and between the export section and the import section: After the transfer chain 3 and the secondary transfer chain 61 are pushed out from any straight section, they move forward under the combined action of the pushing of the rear sprocket and the traction of the front sprocket. If the traction movement amount of the front sprocket is less than the pushing movement amount of the rear sprocket, the transfer chain 3 and the secondary transfer chain 3 will bend freely. If the bending amount reaches the upper limit of the predetermined value, the rear sprocket will pause pushing and wait for the front sprocket to increase the traction movement amount. If the bending amount reaches the lower limit of the predetermined value, the sprocket at the front export section position will pause traction and wait for the rear sprocket to increase the pushing movement amount.

[0124] The specific embodiments are only explanations of the present invention and do not limit the present invention. After reading this specification, those skilled in the art can make modifications to these embodiments without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
