[0002] At present, some hospitals have begun to use medical logistics transmission systems, which can realize the automatic transmission of goods between different floors and rooms of the hospital. This effectively improves the efficiency of logistics transmission in hospitals and ensures the safety of goods transmission. However, for specimen tubes such as blood collection tubes, the timeliness of transmission is higher, and it is difficult to meet the requirements using traditional medical logistics transmission systems. To this end, some companies have begun to develop pneumatic tube logistics transmission systems, which use compressed air to apply power to specimen tubes so that specimen tubes can be transmitted at high speed along the pipeline, greatly improving the transmission efficiency and fully meeting the timeliness requirements of specimen tube transmission. In the entire pneumatic tube logistics transmission system, the sending of specimen tubes involves many links, such as the need to comb and adjust the posture of the specimen tubes, feed the specimen tubes, scan the barcodes on the specimen tubes to record the information of the specimen tubes, and launch the specimen tubes into the pipeline.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0064] In an embodiment of the present invention, a pneumatic tube transmission and sending device for a specimen tube is provided. Figures 1 to 41 shown.

[0065] A pneumatic logistics transmission and sending device for specimen tubes comprises a support frame 1 and a material handling unit, a material feeding unit and a launching unit arranged on the support frame 1.

[0066] A housing 7 is provided outside the support frame 1 and the material handling unit, the feeding unit and the launching unit. A feeding door 71 is provided on the housing 7 at the opening position of the feeding hopper 206, so that the specimen tube 5 can be fed into the feeding hopper 206 through the feeding door 71. A return door 72 is provided on the housing 7 at the position of the return box 40224, and the specimen tube 5 in the return box 40224 can be taken out by opening the return door 72.

[0067] The material sorting unit comprises a material sorting bin 201, a fixing plate 202, a pushing plate 203 and a first driving mechanism.

[0068] The material sorting bin 201 is arranged on the support frame 1 so that the material sorting bin 201 is supported by the support frame 1 .

[0069] Three fixing plates 202 are fixedly connected to the inner wall of one side of the material sorting bin 201 , and the fixing plates 202 extend along the vertical direction.

[0070] A push plate 203 is arranged on the front side of each fixed plate 202. The push plate 203 is slidably connected to the fixed plate 202 or the side wall of the material sorting bin 201. The push plate 203 extends along the vertical direction and can move relative to the fixed plate 202 along the vertical direction.

[0071] The first driving mechanism drives the push plate 203 to move along the vertical direction relative to the adjacent fixed plate 202 .

[0072] Specifically, the first driving mechanism includes a first motor 2041, a rocking arm 2042 and a connecting rod 2043. The output shaft of the first motor 2041 is fixedly connected to one end of the rocking arm 2042. The other end of the rocking arm 2042 is hinged to one end of the connecting rod 2043 via a hinge. The other end of the connecting rod 2043 is hinged to the lower end of the push plate 203 via a hinge. The output shaft of the first motor 2041 rotates to drive the rocking arm 2042 to swing. The rocking arm 2042 pushes or pulls the push plate 203 through the connecting rod 2043 to drive the push plate 203 to move in the vertical direction relative to the adjacent fixed plate 202.

[0073] For the push plates 203 except the frontmost push plate 203 , when the push plates 203 move downward to the limit position along the vertical direction relative to the adjacent fixed plate 202 , the upper end surface of the push plates 203 is flush with the upper end surface of the fixed plate 202 in front of the push plates 203 .

[0074] When the push plate 203 moves upward to the limit position along the vertical direction relative to the adjacent fixed plate 202 , the upper end surface of the push plate 203 is flush with the upper end surface of the fixed plate 202 behind the push plate 203 .

[0075] The material guide plate 205 is located at the bottom of the front side of the material sorting bin 201, and the upper end surface of the material guide plate 205 is arranged to be tilted downward toward the rear. When the frontmost push plate 203 moves downward to the extreme position along the vertical direction relative to the adjacent fixed plate 202, the upper end surface of the frontmost push plate 203 is flush with the upper end surface of the material guide plate 205.

[0076] The feed hopper 206 is located at the front side of the material handling bin 1, and the feed hopper 206 is connected to the material guide plate 205. A plurality of specimen tubes 5 are poured into the feed hopper 206, and the specimen tubes 5 enter the material guide plate 205 along the feed hopper 206.

[0077] Specifically, the upper side and the rear side of the feed hopper 206 are provided with openings, and the upper side edge of the feed hopper 206 is provided with an arc-shaped slide groove 2061 along the front-back direction; the front side of the material sorting bin 201 is provided with an opening, and the front side of the material sorting bin 201 is provided with a slide column 2011 at the upper end of the opening; the lower end of the rear side opening of the feed hopper 206 is hinged to the lower end of the opening of the front side of the material sorting bin 201 through a hinge, and the slide column 2011 is slidably connected to the arc-shaped slide groove 2061. In this way, the feed hopper 206 can be swung toward the inside of the material sorting bin 201 to push the specimen tube 5 in the feed hopper 206 to the material guide plate 205.

[0078] When the first driving mechanism drives the push plate 203 to move in the vertical direction relative to the adjacent fixed plate 202, the specimen tube 5 moves together with the push plate 203, and the specimen tube 5 is transported to the upper end surface of the adjacent fixed plate 202 under the action of inertia. In addition, when the push plate 203 on the front and rear sides of the fixed plate 202 moves, the specimen tube 5 on the upper end surface of the fixed plate 202 continues to be transported to the upper end surface of the adjacent push plate 203.

[0079] The upper end surface of the fixed plate 202 is arranged to be tilted downward toward the rear. In this way, the specimen tube 5 on the upper end surface of the fixed plate 202 slides backward and downward under the action of its own weight, so that the specimen tube 5 fits the push plate 203 on the rear side of the fixed plate 202, and it is convenient for the specimen tube 5 to slide to the upper end surface of the rear side push plate 203. The upper end surface of the push plate 203 is arranged to be tilted downward toward the rear. In this way, the specimen tube 5 on the upper end surface of the push plate 203 slides backward and downward under the action of its own weight, so that the specimen tube 5 fits the fixed plate 202 on the rear side of the push plate 203, and it is convenient for the specimen tube 5 to slide to the upper end surface of the rear side fixed plate 202. The upper end surface of the push plate 203 is set to a rugged non-planar structure to prevent the specimen tube 5 from standing upright on the upper end surface of the push plate 203.

[0080] The operation process of the material sorting unit of the present invention is as follows: a number of specimen tubes 5 are poured into the feed hopper 206, and the specimen tubes 5 enter the guide plate 205 of the material sorting bin 201 along the feed hopper 206. The specimen tubes 5 fall into the upper end surface of the frontmost push plate 203. At this time, the specimen tubes 5 still have various postures. The push plate 203 is driven by the first driving mechanism to move in the vertical direction relative to the adjacent fixed plate 202; when the push plate 203 moves downward in the vertical direction to the extreme position relative to the adjacent fixed plate 202, the upper end surface of the push plate 203 is flush with the upper end surface of the fixed plate 202 in front of the push plate 203, and the specimen tubes 5 on the upper end surface of the fixed plate 202 in front of the push plate 203 fall into the upper end surface of the push plate 203; when the push plate 203 moves upward in the vertical direction to the extreme position relative to the adjacent fixed plate 202, the upper end surface of the push plate 203 The end surface is flush with the upper end surface of the fixed plate 202 at the rear side of the push plate 203, and the specimen tube 5 on the upper end surface of the push plate 203 falls into the upper end surface of the fixed plate 202 at the rear side; the specimen tube 5 moves between the push plate 203 and the fixed plate 202, and the specimen tube 5 is lifted by the push plate 203 and falls into the fixed plate 202 at the rear side. The specimen tube 5 is combed and adjusted from various postures to the posture of "the circumferential side wall of the specimen tube 5 is in contact with the side wall of the push plate 203 or the fixed plate 202 and the specimen tube 5 is horizontal", so as to automatically realize the combing and adjustment of the posture of the specimen tube 5.

[0081] The feeding unit includes a first rotating shaft 3021 , a second rotating shaft 3022 , a second driving mechanism, a first transmission mechanism and a barcode scanner 303 .

[0082] The two ends of the first rotating shaft 3021 are respectively connected to the support frame 1 through bearings for rotation, and the two ends of the second rotating shaft 3022 are respectively connected to the support frame 1 through bearings for rotation. The first rotating shaft 3021 and the second rotating shaft 3022 are arranged side by side, preferably, the first rotating shaft 3021 and the second rotating shaft 3022 are arranged in parallel. A gap is left between the first rotating shaft 3021 and the second rotating shaft 3022, and the upper position between the first rotating shaft 3021 and the second rotating shaft 3022 is used to place the specimen tube 5. It should be noted that the outer diameter of the circumference of the specimen tube 5 is greater than the gap width between the first rotating shaft 3021 and the second rotating shaft 3022.

[0083] The second driving mechanism drives the first rotating shaft 3021 and the second rotating shaft 3022 to rotate via the first transmission mechanism, so that the specimen tube 5 is driven to turn over.

[0084] Specifically, the first transmission mechanism includes a first driving pulley 3051, a first passive pulley 3052, a second passive pulley 3053 and a first transmission belt 3054. The second driving mechanism is connected to the first driving pulley 3051 by power, the first passive pulley 3052 is mounted on one end of the first rotating shaft 3021, the second passive pulley 3053 is mounted on one end of the second rotating shaft 3022, and the first transmission belt 3054 connects the first driving pulley 3051, the first passive pulley 3052 and the second passive pulley 3053. The first driving pulley 3051 is driven to rotate by the second driving mechanism, and the rotation of the first driving pulley 3051 drives the first passive pulley 3052 and the second passive pulley 3053 to rotate via the first transmission belt 3054. At this time, the first rotating shaft 3021 and the second rotating shaft 3022 have the same rotation direction, and the friction torque direction of the first rotating shaft 3021 and the second rotating shaft 3022 on the specimen tube 5 is the same, so that the specimen tube 5 is more easily driven to flip.

[0085] The second driving mechanism is configured as a fourth motor 3061, and the output shaft of the fourth motor 3061 is directly or indirectly connected to the first driving pulley 3051. The output shaft of the fourth motor 3061 rotates to drive the first driving pulley 3051 to rotate.

[0086] Preferably, the output shaft of the fourth motor 3061 is connected to the input end of the reducer 3062, and the output end of the reducer 3062 is connected to the first driving pulley 3051. In this way, the reducer 3062 is decelerated to transmit the set rotation speed to the first driving pulley 3051, so that the first rotating shaft 3021 and the second rotating shaft 3022 rotate at the set rotation speed, driving the specimen tube 5 to flip at the set rotation speed, so as to cooperate with the barcode scanner 303 to scan the barcode on the specimen tube 5.

[0087] The support seat 3031 is disposed at the lower end of the support frame 1, and the barcode scanner 303 is disposed on the support seat 3031. The scanning end of the barcode scanner 303 faces the gap between the first rotating shaft 3021 and the second rotating shaft 3022. The barcode on the specimen tube 5 expresses the information of the specimen tube 5, and the barcode on the specimen tube 5 is exposed from the gap. The barcode scanner 303 scans the barcode on the specimen tube 5 to record the information of the specimen tube 5.

[0088] The material shifting unit is used to move the specimen tube 5 out from the upper position between the first rotating shaft 3021 and the second rotating shaft 3022. Of course, in the absence of the material shifting unit, one end of the first rotating shaft 3021 can be higher than the other end, and one end of the second rotating shaft 3022 can be higher than the other end, so that the specimen tube 5 at the upper position between the first rotating shaft 3021 and the second rotating shaft 3022 can slide from one end to the other end under the action of the weight of the specimen tube 5 itself, so that the specimen tube 5 can be moved out from the upper position between the first rotating shaft 3021 and the second rotating shaft 3022.

[0089] The material-picking unit includes a second driving pulley 3071 , a third driven pulley 3072 , a second transmission belt 3073 and a fourth driving mechanism.
