Description

Technical Field

[0001] This application relates to the field of logistics transmission equipment technology, and more specifically, to a logistics system for hospitals. Background Technology

[0002] Hospital logistics is the core of hospital support management and an extension of logistics into the medical field. Currently, commonly used material handling devices in the medical field include pneumatic pipeline logistics systems, rail-guided trolleys, box-type logistics systems, and AGVs (Automated Guided Vehicles).

[0003] Pneumatic tubing logistics is one of the most commonly used logistics methods in the medical field, characterized by its small size, high speed, and low investment. However, the high transmission speed of pneumatic tubing logistics can easily lead to abnormal biochemical indicators. Furthermore, the high pressure used in pneumatic tubing logistics results in poor control reliability and the possibility of lost goods.

[0004] The railcar has a transport capacity of around 35 kg and its terminal is relatively simple, making it a logistics technology that hospitals currently rely on. However, it is relatively slow (0.6 m / s) and has poor timeliness (round trips typically take more than 30 minutes, with significant time spent requesting dispatch from the depot). It is unsuitable for transporting medical samples and emergency medicines; furthermore, the cargo tends to tip over inside the container, making it unsuitable for transporting food or similar items; and if devices to prevent cargo tipping are used, the effective volume will be greatly reduced. Equipment procurement and maintenance are expensive (track cleaning, refueling, and maintenance standards are strict), placing a heavy financial burden on hospitals.

[0005] Box-type logistics consists of elevators and roller conveyors or belt conveyors, offering good horizontal continuous transport capabilities. However, its vertical freight elevators provide back-and-forth transport, resulting in a mismatch between vertical and horizontal transport capabilities. Furthermore, box-type logistics equipment is heavy, consumes a lot of power, has complex terminal technologies, and incurs high equipment procurement and maintenance costs.

[0006] AGVs have the highest single-carry capacity and require no complex installation, making them ideal for surgical instruments and food delivery, and are currently the best door-to-door logistics transport device. However, they have two drawbacks: 1. Low speed and poor timeliness, suitable only for bulk items with low time sensitivity. 2. Requires dedicated channels, including dedicated elevators, which are expensive.

[0007] In summary, current logistics devices in the medical field cannot fully meet the transportation needs of medical supplies, and many suffer from complex structures and high procurement costs, leading to high installation and operating costs for hospitals. Summary of the Invention

[0008] The purpose of this application is to provide a hospital logistics system that can meet the transportation needs of various medical supplies, and also features a simple structure and low manufacturing cost.

Detailed Implementation

[0097] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0098] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0099] Figure 1 This is a schematic diagram illustrating the structure of a hospital logistics system according to an embodiment of this application. See also... Figure 1 The hospital logistics system includes a vertical lifting device 100 and a horizontal conveying device 200. 、 Turnover box 300 and adapter 400.

[0100] The turnover box 300 is used to load medical supplies. The turnover box 300 comes in different sizes. The size of the turnover box 300 is set according to the volume of the medical supplies.

[0101] The vertical lifting device 100 includes a frame and a synchronous belt device 110 mounted on the frame. The synchronous belt device 110 includes at least one splicing synchronous belt loop 111 and receiving devices 112 arranged circumferentially at intervals on each splicing synchronous belt loop 111. The turnover box 300 is received by one or two receiving devices 112 on the splicing synchronous belt loops 111 and moves vertically to a designated parking position on a predetermined floor, following the receiving devices 112. The horizontal transmission device 200 is arranged within the predetermined floor and includes a transmission track 210, a guide synchronous belt 220, and a traction mechanism 230. The traction mechanism 230 follows the guide synchronous belt 220 and drives the turnover box 300 to move along the transmission track 210 to a designated position on the floor. A transfer device 400 is located in the boundary area between the parking position of the vertical lifting device 100 on each floor and the horizontal transmission device 200 on that floor, for transferring the turnover box 300 between the vertical lifting device 100 and the horizontal transmission device 200.

[0102] In the above implementation process, the turnover box 300 can be loaded with medical supplies of different volumes to meet different transportation needs. Compared to complex and power-consuming transmission equipment, the frame and synchronous belt device 110 in the vertical lifting device 100 have the advantages of simple structure and low manufacturing cost. The synchronous belt device 110 forms one or two spliced ​​synchronous belt loops 111, and the circumferentially arranged receiving device 112 of the one or two spliced ​​synchronous belt loops 111 enables the continuous transmission of multiple turnover boxes 300 in a single vertical transmission process. Compared to existing vertical freight elevators that can only transport one item per round trip, the transmission efficiency of the synchronous belt device 110 is significantly improved. The horizontal transmission device 200 in this application still adopts a synchronous belt structure. The production cost of synchronous belts is low, and the design of its internal rack can accurately calculate the distance the synchronous belt moves. Therefore, the horizontal transmission device 200 in this application reduces manufacturing costs while allowing the turnover boxes 300 to move accurately and quickly to the designated location following the movement of the synchronous belt. In this application, after the vertical lifting device 100 lifts the turnover box 300 to a specified height, the transfer device 400 can quickly transfer the turnover box 300 to the horizontal transmission track 210. Therefore, the vertical conveying capacity and the horizontal conveying capacity in this application can be well matched, greatly improving the transmission efficiency.

[0103] Figure 2 This is a schematic diagram illustrating the structure of a turnover box according to an embodiment of this application. See also... Figure 2 The turnover box 300 includes a box body and hook edges 310 provided on two opposite sides of the box body. The hook edges 310 have a simple structure and are easy to erect on other structures.

[0104] Figure 3 This is a schematic diagram illustrating the structure of another turnover box according to an embodiment of this application. See also... Figure 3 The turnover box 300 may also be equipped with a hanging handle 320. Two fixed support rods 330 are respectively provided on two opposite sides of the turnover box 300, and a hanging handle 320 is provided on each of the two fixed support rods 330. The connection points between the two fixed support rods 330 and the hanging handles 320 are all at a predetermined distance from the end of the hanging handles 320, that is, each hanging handle 320 has a reserved hanging section at both ends for hanging with the receiving device 112.

[0105] It should be noted that the above-described structure using the hanging edge 310 or hanging handle 320 is merely exemplary. This application does not specifically limit the hanging structure of the turnover box 300. Any structure capable of being hung, such as a hook structure, can be referred to... Figure 2 All of these fall within the scope of protection of this application.

Figure 4 The splicing synchronous belt ring 111 includes a first synchronous belt 1110 with its toothed surface on the inner side and its smooth surface on the outer side. The smooth surface of the first synchronous belt 1110 forms a first side and a second side with a predetermined height and opposite orientation in the vertical direction. The receiving device 112 moves cyclically between the first side and the second side as the splicing synchronous belt ring 111 moves.

[0108] In one implementation, the receiving device 112 is equipped with a hanging beam structure. The hanging beam structure of the receiving device 112 is bolted to the smooth surface of the splicing synchronous belt ring 111, and the hanging beam structure is equipped with U-shaped or L-shaped hooks. The hooking edge 310 or hooking handle 320 on the turnover box 300 engages with the U-shaped or L-shaped hooks. To ensure that the turnover box 300 can be transported vertically from only one side, the hooking edge 310 or hooking handle 320 of the turnover box 300 may also be equipped with a slot or inverted U-shaped hook structure that engages with the U-shaped or L-shaped hooks, see [reference]. Figure 2 .

[0109] In another implementation, see Figure 4 The receiving device 112 includes a first upper hanging beam 113 and a first lower hanging beam 114. The first upper hanging beam 113 and the first lower hanging beam 114 extend a predetermined length in the width direction of the smooth surface of the first synchronous belt 1110, and are separated by a predetermined distance in the vertical direction. A fifth set of hooks 115 is rigidly connected to the first upper hanging beam 113, and a sixth set of hooks 116 is rigidly connected to the first lower hanging beam 114. The relationship between the first upper hanging beam 113, the first lower hanging beam 114, and the turnover box 300 is configured such that the fifth set of hooks 115 and the sixth set of hooks 116 face opposite directions, and the vertical distance between the fifth set of hooks 115 and the sixth set of hooks 116 is less than the height of the turnover box 300. When on the first side, the first upper hanging beam 113 hangs the turnover box 300, and the sixth set of hooks 116 is used to support the lower part of the turnover box 300; when the receiving device 112 moves to the second side, the first lower hanging beam 114 hangs the turnover box 300, and the fifth set of hooks 115 is used to support the lower part of the turnover box 300.

[0110] Figure 5 This is a schematic diagram illustrating the structure of another vertical lifting device according to an embodiment of this application. See also... Figure 5The splicing synchronous belt ring 111 includes two first synchronous belts 1110 with toothed surfaces on the inner side and smooth surfaces on the outer side. The two first synchronous belts 1110 form an integral splicing synchronous belt ring 111. The smooth surfaces of the two first synchronous belts 1110 form a first side and a second side with a predetermined height, a gap in the middle, and opposite orientations in the vertical direction. The receiving device 112 moves cyclically between the first side and the second side as the splicing synchronous belt ring 111 moves.

[0111] For the vertical lifting device 100 of this structure, various receiving devices 112 can be set to hang the turnover box 300.

[0112] See Figure 5 The receiving device 112 includes a first hanging beam 117, a first set of hooks 118 and a second set of hooks 119 rigidly connected to the first hanging beam 117; the first hanging beam 117 extends along the width direction of the smooth surface of the first synchronous belt 1110 and is fixed on a first side or a second side. The first set of hooks 118 and the second set of hooks 119 are spaced apart by a predetermined distance in the width direction of the smooth surface of the first synchronous belt 1110, and both extend a predetermined length in a direction perpendicular to the length of the first hanging beam 117. The first set of hooks 118 and the second set of hooks 119 are used to hang the turnover box 300. The receiving device 112 also includes a third set of hooks 120 and a fourth set of hooks 121. The first set of hooks 118 and the third set of hooks are arranged mirror images of the horizontal center plane of the first hanging beam 117; the second set of hooks 119 and the fourth set of hooks 121 are also arranged mirror images of the horizontal center plane of the first hanging beam 117.

[0113] In the above structure, when located on the first side, the first set of hooks 118 and the second set of hooks 119 in a receiving device 112 are used to support the turnover box 300. When rotating to the second side with the first synchronous belt 1110, the third set of hooks 120 and the fourth set of hooks 121 in the receiving device 112 are used to support the turnover box 300. The hanging beam structure in this structure can not only be compatible with turnover boxes 300 of different sizes, but also can support turnover boxes 300 on both the first and second sides. Therefore, it can realize bidirectional vertical continuous transmission of turnover boxes 300 and improve transmission capacity.

[0114] Figure 6 This is a schematic diagram of another receiving device according to an embodiment of this application. Figure 7 for Figure 6 A front view of a receiving device in the structure shown. See also Figure 6 and Figure 7The receiving device 112 includes a second upper hanging beam 122, a second lower hanging beam 123, and two receiving frames 124. The second upper hanging beam 122 and the second lower hanging beam 123 are arranged vertically at intervals and both extend a predetermined length along the width of the smooth surface of the first synchronous belt 1110. The two receiving frames 124 are arranged at a predetermined distance apart in the width direction of the smooth surface. When the first synchronous belt 1110 rotates to the top of the synchronous belt device 110, the receiving frames can rotate relative to the second upper hanging beam 122 and the second lower hanging beam 123, and the three do not interfere with each other during the rotation of the receiving frames. The turnover box 300 is supported by the two receiving frames 124.

[0115] In one implementation, the receiving frame 124 includes a first receiving rod 1240, a second receiving rod 1241, and a first connecting rod 1242. The length of the first receiving rod 1240 is greater than the sum of the lengths of the second receiving rod 1241 and the first connecting rod 1242. The first receiving rod 1240 is hinged to a second lower hanging beam 123, and the second receiving rod 1241 is hinged to a second upper hanging beam 122, with the hinge position located directly above the first receiving rod 1240. One end of the first connecting rod 1242 is hinged to the first receiving rod 1240, and the other end is hinged to the second receiving rod 1241. The two receiving frames 124 are configured such that, when located on the first side, the second receiving rod 1241 and the first connecting rod 1242 are horizontally arranged, and the second receiving rod 1241 and the first connecting rod 1242 are provided with a seventh set of hooks for hanging the turnover box 300, and the first receiving rod 1240 is in an inclined upward state; when located on the second side along with the first synchronous belt 1110, the first receiving rod 1240, the connecting rod and the second receiving rod 1241 are all in an inclined downward state.

[0116] In the above process, when the two receiving frames 124 are on the first side, the turnover box 300 is vertically lifted or lowered by the hooks on the two second receiving rods 1241.

[0117] Figure 8 This is a schematic diagram of another receiving device according to an embodiment of this application. Figure 8 The receiving device and Figure 6 The supporting devices shown are similar, differing only in their support frame structure. See also Figure 8 The receiving device 112 includes a second upper hanging beam 122, a second lower hanging beam 123, and two receiving frames 124. Each receiving frame includes a third receiving rod 1243, a fourth receiving rod 1244, and a second connecting rod 1245.

[0118] One end of the fourth receiving rod 1244 is rotatably connected to the second lower hanging beam 123, and the other end is rotatably connected to one end of the second connecting rod 1245. One end of the third receiving rod 1243 is rotatably connected to the second upper hanging beam 122, and the other end is rotatably connected to a section of the second connecting rod 1245. The two ends of the second connecting rod 1245 are hinged to the ends of the third receiving rod 1243 and the fourth receiving rod 1244, respectively. The fourth receiving rod 1244 is equipped with an eighth set of hooks 1246, and the third receiving rod 1243 is equipped with a ninth set of hooks 1247.

[0119] The two receiving frames 124 are configured such that, when located on the first side, the third receiving rod 1243 and the second connecting rod 1245 are used to suspend the fourth receiving rod 1244, which is horizontally positioned or inclined upward relative to the horizontal direction, and the eighth set of hooks 1246 of the two fourth receiving rods 1244 are used to receive the transmitted load; and when rotated to the second side with the first synchronous belt 1110, the fourth receiving rod 1244 and the second connecting rod 1245 are used to suspend the third receiving rod 1243, which is horizontally positioned or inclined upward relative to the horizontal direction, and the ninth set of hooks 1247 of the two third receiving rods 1243 are used to receive the turnover box 300.

[0120] In one possible implementation, the third and fourth support rods 1243 and 1244 of the support frame 124 are of equal length. When positioned on the first side, the center lines connecting the connection points of the third support rod 1243 and the second lower hanging beam 123, and the fourth support rod 1244 and the second upper hanging beam 122, as well as the center line connecting the fourth support rod 1244 and the second connecting rod 1245, and the center line of the third support rod 1243, form a right-angled triangle. When positioned on the second side, the center lines connecting the connection points of the third support rod 1243 and the second lower hanging beam 123, and the fourth support rod 1244 and the second upper hanging beam 122, as well as the center line connecting the third support rod 1243 and the second connecting rod 1245, and the center line of the fourth support rod 1244, form a right-angled triangle.

[0121] Figure 9 This is a schematic diagram of another receiving device according to an embodiment of this application. Figure 9 The receiving device and Figure 6 The supporting devices shown are similar, differing only in their support frame structure. See also Figure 9 The support frame 124 includes a fifth support rod 1248 and a sixth support rod 1249.

[0122] One end of the sixth receiving rod 1249 is rotatably connected to the second lower hanging beam 123, and the other end is rotatably connected to one end of the fifth receiving rod 1248. One end of the fifth receiving rod 1248 is rotatably connected to the second upper hanging beam 122, and the other end is rotatably connected to a section of the sixth receiving rod 1249; the sixth receiving rod 1249 is equipped with a tenth set of hooks 1250 and an eleventh set of hooks 1251 that are oriented in opposite directions in the vertical direction.

[0123] The two support frames 124 are configured such that, when located on the first side, the fifth support rod 1248 is used to suspend the sixth support rod 1249, which is horizontally positioned, and the tenth set of hooks 1250 of the two sixth support rods 1249 are vertically upward for receiving the transmitted load; and when rotated to the second side with the first synchronous belt 1110, the fifth support rod 1248 is used to support the sixth support rod 1249 at an angle upward, which is horizontally positioned, and the eleventh set of hooks 1251 of the two sixth support rods 1249 are vertically upward for receiving the transmitted load.

[0124] In the above implementation process, the receiving frame only needs two receiving rods to mount the transmitted load. The structure is simple and not prone to failure during the transfer process, and has the advantages of being simple and reliable.

[0125] It should be noted that the structures of the various support frames described above are merely exemplary. This application does not specifically limit the structure of the support frame; any structure capable of supporting the turnover box 300 falls within the protection scope of this application. It should also be noted that... Figure 5 In the vertical lifting device 100 shown in the structure, the use of two synchronous belts for the first synchronous belt 1110 is merely exemplary; the number of first synchronous belts 1110 can be greater than two. The smooth surfaces of the two or more first synchronous belts 1110 can form a first side and a second side with a predetermined height and opposite orientations in the vertical direction.

[0126] In another embodiment of the vertical lifting device 100, the timing belt device 110 in the vertical lifting device 100 includes two spliced ​​timing belt loops 111.

[0127] Figure 10 This is a schematic diagram illustrating the structure of another vertical lifting device according to an embodiment of this application. See also... Figure 10 Two spliced ​​synchronous belt loops 111 are aligned at the same height and horizontally spaced a predetermined distance apart. The two spliced ​​synchronous belt loops 111 rotate at the same speed but in opposite directions. The two spliced ​​synchronous belt loops 111 form a vertical transmission space. In this embodiment, the structure of the spliced ​​synchronous belt loops 111 can adopt... Figure 4 The spliced ​​synchronous belt ring 111 structure shown can also be adopted. Figure 5The splicing synchronous belt ring 111 structure shown is illustrated.

[0128] In the vertical lifting device 100 of this structure, the receiving device 112 includes a first supporting mechanism 1120 and a second supporting mechanism 1121. The first supporting mechanism 1120 is disposed on one of the splicing synchronous belt rings 111, and the second supporting mechanism is disposed on the other splicing synchronous belt ring 111. The first supporting mechanism 1120 includes a second hanging beam, a first hook group and a second hook group rigidly connected to the second hanging beam. The second hanging beam extends along the bandwidth direction of the splicing synchronous belt ring 111 and is fixed on the smooth surface of the splicing synchronous belt ring 111; the first hook group and the second hook group are spaced apart by a predetermined distance in the bandwidth direction of the splicing synchronous belt ring 111, and both extend a predetermined length in a direction perpendicular to the length of the second hanging beam. The second supporting mechanism 1121 includes a third hanging beam, a third hook group and a fourth hook group rigidly connected to the third hanging beam. The third hanging beam extends along the bandwidth direction of the splicing synchronous belt ring 111 and is fixed on the smooth surface of the splicing synchronous belt ring 111. The third and fourth hook groups are spaced a predetermined distance apart in the bandwidth direction of the splicing synchronous belt ring 111, and both extend a predetermined length in a direction perpendicular to the length of the third hanging beam. The first, second, third, and fourth hook groups together hang a turnover box 300.

[0129] Figure 11 This is a schematic diagram illustrating the structure of yet another vertical lifting device according to an embodiment of this application. See also... Figure 11 The synchronous belt device 110 comprises two spliced ​​synchronous belt rings 111, one of which is located at a predetermined position inside the other. The smooth surfaces of the two spliced ​​synchronous belt rings 111 are parallel, of equal width, and arranged opposite each other. The rotational speed and direction of the two spliced ​​synchronous belt rings 111 are the same. The two spliced ​​synchronous belt rings 111 form two vertical transmission spaces that are horizontally separated by a predetermined distance.

[0130] In this embodiment, the circumference of both spliced ​​synchronous belt rings 111 is an integer multiple of M, where M is the length of the synchronous belt segment corresponding to a predetermined number of teeth. One or more receiving devices 112 are configured within the synchronous belt segment. The circumference of the outer spliced ​​synchronous belt ring 111 is KM more than that of the inner spliced ​​synchronous belt ring 111, where K is an integer greater than or equal to 2. In each vertical transmission space, the smooth surfaces of the two spliced ​​synchronous belt rings 111 can be arranged opposite each other or facing one side. Within the same vertical height range, the number of synchronous belt segments is the same, and the start and end points of each synchronous belt segment are aligned at the same height. The receiving units within the two synchronous belt segments aligned at the same height have the same vertical spacing pattern. For example, if one synchronous belt segment has 1 receiving unit, then the other synchronous belt segment at the same height also has 1 receiving unit; if one synchronous belt segment has 3 receiving units, then the other synchronous belt segment at the same height also has 3 receiving units, and all 3 receiving units are at the same height. A receiving unit in one synchronous belt segment and a receiving unit in another synchronous belt segment of the same height constitute a receiving device 112. That is, there can be one or more receiving devices 112 in one synchronous belt segment.

[0131] exist Figure 11 In the vertical lifting device 100 shown, the structure of the receiving device 112 can be compared with... Figure 10 The same supporting structure is used in the process, and the supporting device 112 can be further optimized. Specifically, the first supporting mechanism 1120 also includes a fifth hook group and a sixth hook group; the fifth hook group and the sixth hook group are arranged in a mirror image arrangement with respect to the horizontal center plane of the second hanging beam, as opposed to the first hook group and the second hook group. The second supporting mechanism 1121 also includes a seventh hook group and an eighth hook group; the seventh hook group and the eighth hook group are arranged in a mirror image arrangement with respect to the horizontal center plane of the third hanging beam, that is, adopting the same... Figure 5 The receiving device has the same structure as shown.

[0132] The relationship between the bearing device of each of the above vertical lifting devices 100 and the turnover box 300 is configured as follows: the hanging beam structure provided on the bearing device receives the hanging edge 310 / handle and can drive the turnover box 300 to move in the vertical direction, and after the turnover box 300 is raised to a predetermined height by external force, the hanging edge 310 / handle disengages from the hanging beam structure.

[0133] Figure 12 This is a schematic diagram illustrating the structure of an adapter 400 according to an embodiment of this application. See also... Figure 12 The adapter 400 includes a truss 410 and a lifting cantilever 420.

[0134] A truss 410 is positioned beside the vertical lifting device 100. A horizontal slide rail 411, a vertical slide rail 412, and a lifting drive device 413 that moves the horizontal slide rail 411 along the vertical slide rail 412 are mounted on the truss 410. A retrieval cantilever 420 is mounted on the horizontal slide rail 411 and is equipped with a sliding retrieval platform. The sliding retrieval platform extends to the side of the vertical lifting device 100 where the receiving device 112 is located. After moving a predetermined distance on the horizontal slide rail 411, it reaches directly below the turnover box 300 and, driven by the lifting drive device 413, contacts and supports the turnover box 300 until the turnover box 300 detaches from the hanging beam structure.

[0135] After the turnover box 300 is separated from the hanging beam structure, the sliding retrieval platform takes out the turnover box 300 according to the predetermined movement trajectory.

[0136] Figure 13 This is a layout diagram of the vertical lifting device and the horizontal conveying device in a hospital logistics system according to an embodiment of this application. See also... Figure 13 The horizontal conveyor 200 is located beside the vertical lifting device 100 and above the transfer device 400. After the sliding retrieval platform in the transfer device 400 retrieves the turnover box 300 from the vertical lifting device 100 and returns it to its initial position along the original route, it lifts the turnover box 300 to a predetermined height. At this height, the height of the hanging edge / handle of the turnover box 300 is higher than the height of the suspension beam. Subsequently, the sliding retrieval platform advances a predetermined length along the length direction of the conveyor track 210 in the horizontal conveyor 200 and stops, then moves downward to its original position under the drive of the lifting drive device 413. During its descent, the turnover box 300 is supported by the suspension beam, thus achieving the attachment of the turnover box 300 on the horizontal conveyor 200. The turnover box 300 is then transported to a designated location by the movement of the guide synchronous belt 220.

[0137] It should be noted that, Figure 13 The vertical lifting device 100 used in the process is Figure 11 The vertical lifting device 100 shown in the diagram requires the retrieval cantilever 420 to extend into the vertical transport space of the vertical lifting device 100 to retrieve the turnover box 300. If the hospital logistics system in this application adopts... Figure 5 or Figure 10 The vertical lifting device 100 shown indicates that the lifting cantilever 420 removes the turnover box 300 in the same way as... Figure 13 The method of retrieving the turnover box 300 by the cantilever 420 is the same. If the hospital logistics system in this application adopts... Figure 4 The vertical lifting device 100 shown allows the retrieval cantilever 420 to be moved to a predetermined position below the turnover box 300 and then raised to a predetermined height to remove the turnover box 300. If the hospital logistics system in this application adopts... Figure 6-9The vertical lifting device 100 shown requires the lifting arm 420 to be moved below the turnover box 300 and then raised to a predetermined height. After the turnover box 300 is removed from the support frame, it is moved out of the support frame to retrieve the turnover box 300.

[0138] See Figure 13 When the vertical lifting device 100 includes two vertical transmission spaces, and both transmission spaces are capable of transmitting the turnover box 300, a transfer device 400 can be set on each side of the vertical lifting device 100 to transfer the turnover box 300 in the two vertical transmission spaces respectively.

[0139] In one embodiment, the retrieval arm 420 is rotatable on a horizontal plane. Rotation of the retrieval arm 420 on the horizontal plane allows adjustment of the angle at which the receiving container 300 is located, and after receiving the container 300, it can also rotate the container 300 to move it to a predetermined position on the horizontal conveying device 200 at a suitable angle.

[0140] In one embodiment, the adapter 400 further includes a limiting device 430. The limiting device 430 is disposed on the sliding pick-up stage and includes at least two clamping devices. See also Figure 12 The limiting device 430 includes four clamping devices, which are respectively disposed on the periphery of the four sides of the turnover box 300. These devices are used to straighten the turnover box 300 to a predetermined position and prevent it from sliding off the sliding platform after it has been placed on the platform. It should be noted that this application does not specifically limit the structural form of the limiting device 430; any structure capable of straightening the turnover box 300 to a predetermined position and preventing it from sliding off the sliding platform falls within the protection scope of this application.

[0141] The structure of the horizontal transmission device 200 in this application will be described in detail below.

[0142] Figure 14 This is a partial structural schematic diagram of a horizontal transmission device according to an embodiment of this application. See also... Figure 14 The horizontal conveying device 200 includes a conveying track 210 comprising a first track 211 and a second track 212 arranged at intervals and in parallel. The traction mechanism 230 includes a traction rod structure 231 connected to a guide timing belt 220, a support frame 232 connected to the traction rod structure 231 and equipped with support wheels, and a suspension beam structure 233 located at the bottom of the support frame 232 and capable of suspending the turnover box 300. The support frame 232 moves on the conveying track 210 via the support wheels, and the suspension beam structure 233 is located within the gap between the first track 211 and the second track 212.

[0143] The relationship between the turnover box 300 and the suspension beam structure 233 is configured such that the suspension beam structure 233 receives the hook edge 310 / handle and can drive the turnover box 300 to move in the horizontal direction, and the hook edge 310 / handle disengages from the suspension beam structure 233 after the turnover box 300 is raised to a predetermined height by an external force.

[0144] Figure 15 This is a schematic diagram illustrating a suspended beam structure according to an embodiment of this application. See also... Figure 15 The suspension beam structure 233 includes multiple sets of suspension beams capable of suspending turnover boxes 300 of different sizes. These multiple sets of suspension beams include a first suspension beam 2330, a second suspension beam 2331, and a third suspension beam 2332. The first suspension beam 2330 is used to suspend small turnover boxes 300; the second suspension beam 2331 is used to suspend medium-sized turnover boxes 300; and the third suspension beam 2332 is used to suspend large turnover boxes 300. Therefore, the suspension beam structure 233 can accommodate turnover boxes 300 of different sizes, exhibiting wider applicability.

The other end of the first traction rod 235 is rotatably connected to the support frame 232.

[0146] In another embodiment, the guide timing belt 220 is located on the upper part of the turnover box 300. Figure 17 This is a schematic diagram illustrating another traction rod structure according to an embodiment of this application. See also... Figure 17 The traction structure includes a second fixed link 236. The second fixed link 236 is arranged parallel to the smooth width direction of the guide synchronous belt 220 and fixed on the guide synchronous belt 220; one end of the second fixed link extends beyond the width range of the guide synchronous belt 220 and is rotatably connected to the support frame 232.

[0147] In one possible implementation, the guide synchronous belt 220 is guided by a synchronous belt guide structure. Figure 18 This is a schematic diagram illustrating a synchronous belt guide structure according to an embodiment of this application. See also... Figure 18The synchronous belt guide structure 500 includes a guide wheel mounting bracket 510 and at least one guide wheel 520. The guide wheel mounting bracket 510 includes a first mounting plate 511, a second mounting plate 512, and a fixing assembly 513. A plurality of guide wheels 520 are disposed between the first mounting plate 511 and the second mounting plate 512. The fixing assembly 513 connects the first mounting plate 511 and the second mounting plate 512 and fixes the guide wheels 520 between them. The guide wheels 520 are configured with an arc-shaped guide surface; the synchronous belt 220 is wound around the arc-shaped guide surface, and the belt surface of the synchronous belt is vertically positioned during rotation.

[0148] In one possible implementation, the synchronous belt guide structure also includes a tensioning device. Figure 19 This is a schematic diagram illustrating a synchronous belt guide structure according to an embodiment of this application. See also... Figure 19 The tensioning device 530 includes a first suspension frame 531 and a tensioning device body 532. The first suspension frame 531 is used to fix the tensioning device body 532 in a predetermined position. The tensioning device body 532 is installed between the first suspension frame 531 and the guide wheel mounting frame 510, and includes a guide rail mechanism 533 that defines the movement path of the guide wheel mounting frame 510, and a push mechanism 534 that pushes the arc-shaped guide surface of the guide wheel mounting frame 510 to move along the movement path to tension the guide synchronous belt 220.

[0149] Figure 20 This is a diagram illustrating one possible transport path for a turnover box in a horizontal transport device according to an embodiment of this application. See also... Figure 20 The transmission path of the horizontal transmission device 200 is a closed loop. In this horizontal transmission device 200, one set of synchronous belt guide structures is selected as the driving pulley set, and the other synchronous belt guide structures are driven pulley sets. The guide pulleys in the driving pulley set are driven by a motor, and the synchronous belt rotates under the drive of the motor, guided by the arc-shaped guide surfaces of the other synchronous belt guide structures. When the synchronous belt becomes slack during rotation, it is tensioned using a tensioning device.

[0150] Figure 21 This is an alternative transport path diagram for a turnover box in a horizontal transport device according to an embodiment of this application. See also Figure 21 The transmission path of the horizontal transmission device 200 is a curved path of a predetermined length. In this horizontal transmission device 200, the guide synchronous belt 220 can be set inside the moving track of the support frame 232 or outside the moving track of the support frame 232. Figure 20Taking the inner side as an example, the horizontal transmission device 200 in this embodiment has a driven pulley set as the synchronous belt guide structure. At both ends of the movement path, one is set as the driving pulley set, and the guide wheel in the driving pulley set is driven by a motor; the other is set as the tensioning pulley set, and when the synchronous belt becomes slack during rotation, the guide synchronous belt 220 is tensioned by means of a tensioning device.

[0151] As can be seen from the above technical solutions, the vertical lifting device 100 of the medical logistics system in this application has the advantages of simple structure and low manufacturing cost compared with the existing complex and power-consuming transmission equipment. The synchronous belt used in the synchronous belt structure of the horizontal transmission device has low production cost, and its internal rack design can accurately calculate the distance the synchronous belt moves. While reducing manufacturing costs, the turnover box 300 can move precisely and quickly to the designated location following the synchronous belt. The transfer device 400 can quickly transfer the turnover box 300 to the horizontal transmission track 210, and both the vertical lifting device 100 and the horizontal transmission device 200 in this application can meet the transmission needs of turnover boxes 300 of different sizes. Therefore, the medical logistics system in this application can meet the transmission needs of various medical supplies, and also has the characteristics of simple structure and low manufacturing cost.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0153] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

[0154] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
