Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production, and in particular to a sterilization vehicle disassembly and assembly device, as well as an automated logistics transfer system equipped with the sterilization vehicle disassembly and assembly device. Background Technology

[0002] The sterilization cart is typically transferred from the bag-loading station to the sterilization cabinet using a transfer track, either manually or automatically. This method of transfer is labor-intensive, difficult to temporarily store items en route, and carries the risk of errors and batch mixing during storage and transfer. Utility Model Content

[0003] The inventors discovered that the disassembly and assembly device of the sterilization vehicle originally used for manual transfer was inefficient and did not work well with the AGV of the transfer sterilization vehicle, and needed to be improved.

[0004] The purpose of this utility model is to provide an automated logistics transfer system for sterilization vehicles that features a novel and unique structure, is easy to use, and employs AGV (Automated Guided Vehicle) transfer sterilization vehicles. The specific technical solution is as follows:

[0005] A sterilization cart disassembly and assembly device includes a frame, a robotic arm, and a lifting mechanism for driving the robotic arm to reciprocate up and down; the frame is provided with vertically extending guide rails, the robotic arm is provided with a slider that cooperates with the guide rails, the lifting mechanism is hinged to the robotic arm, and the front end of the robotic arm is provided with a retractable locking tongue for lifting the sterilization cart.

[0006] Furthermore, the pushing motion of the pushing mechanism is between 1.1 and 1.5 times the height of the sterilization tray.

[0007] Furthermore, it also includes a sterilization cart support frame, the height of which is adapted to the AGV of the transfer sterilization cart.

[0008] This utility model also discloses an automated logistics transfer system for sterilization vehicles, including an AGV and a sterilization vehicle disassembly and assembly device. The AGV is equipped with a lifting tray that supports the sterilization vehicle, and the sterilization vehicle disassembly and assembly device is the aforementioned sterilization vehicle disassembly and assembly device.

[0009] This utility model's automatic logistics transfer system for sterilization carts uses a robotic arm's locking tongue to insert into the transfer slot of the sterilization tray; a lifting mechanism raises the sterilization tray, separating the bottom sterilization tray of the sterilization cart from the whole, facilitating transfer by the transfer mechanism; it is convenient for the assembly and disassembly of the sterilization cart, with a simple structure and small size.

[0016] The present invention will be described more fully below with reference to embodiments. The present invention may be embodied in many different forms and should not be construed as being limited to the exemplary embodiments described herein.

[0017] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of another element or feature would be positioned “up” of that other element or feature. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0018] like Figure 4 As shown, the sterilization trays comprising the sterilization cart 2 have rectangular frames; splicing holes 22 and splicing pins 23 are provided on the front and rear sides of the frame; the splicing holes are located on the top surface of the frame, and the splicing pins are located on the bottom surface of the frame; or vice versa. The positions of the splicing holes and the splicing pins are adapted to each other. During splicing, the splicing pin of the upper sterilization tray is inserted into the splicing hole of the lower sterilization tray, limiting the horizontal displacement of the upper and lower sterilization trays on the splicing surface. Rear transfer grooves 21 are provided on the side walls of the left and right sides of the frame; the upper edge of the transfer groove has a sufficiently thick support edge to withstand the pressure applied by the lifting part during transfer in the sterilization cart.

[0019] The top surface of the sterilization tray is equipped with an infusion bag placement platform 24, which consists of several inclined slopes. Infusion bag tube slots or baffles can be installed to make the infusion bags more neatly placed. Through holes can be set on the slopes and the bottom of the slopes to reduce water accumulation and avoid affecting the sterilization effect. Example 1

[0020] like Figure 1 , Figure 2 As shown, the sterilization cart disassembly and assembly device in this embodiment includes a frame 31, a robotic arm 35, and a lifting mechanism 3 that drives the robotic arm to move up and down reciprocally. The lifting part of the lifting mechanism pushes the robotic arm into the transfer groove of the sterilization tray on the second-to-last layer of the sterilization cart, leaving the bottom sterilization tray. The remaining sterilization tray is then lifted up to a height greater than that of the bottom sterilization tray.

[0021] The sterilization cart support frame 1 connects to the transfer rail. A robotic arm or other existing towing device pulls or pushes the bottom sterilization trays onto the transfer rail for transport to the next workshop. Ideally, the height of the transfer rail should match the support plane of the sterilization cart support frame, ensuring that the height of the sterilization trays remains essentially constant as they are transferred from the support frame to the transfer rail. This allows for simpler towing devices, such as pushing or pulling. Alternatively, a robotic arm can be used to grip or drag the sterilization trays, but this is more expensive.

[0022] When the bottom sterilization tray is transferred to a position that does not interfere with the lowering of the sterilization cart, the lifting mechanism drives the robotic arm to lower the remaining sterilization trays in the sterilization cart. The sterilization cart is then placed on the sterilization cart support frame, and the lifting part is retracted to avoid hitting the support edge of the bottom sterilization tray. It then rises to the height corresponding to the transfer slot of the second-to-last sterilization tray, completing one disassembly step. The disassembly steps are repeated until the last sterilization tray is transferred away.

[0023] In this embodiment, the sterilization cart disassembly and assembly device has a lifting mechanism 3 with a range of motion slightly greater than the height of one layer of sterilization cart; it has a compact structure and high efficiency; the sterilization cart support frame can be designed to be low so that AGVs with lower lifting heights can directly enter the sterilization cart support frame; and the sterilization cart is placed on the sterilization cart support frame.

[0024] like Figure 3 , Figure 5 As shown, in order to support the heavy sterilization cart, the frame 31 of the lifting mechanism is equipped with vertically extending guide rails 33, and the robotic arm is equipped with a slider 34 that cooperates with the guide rails. The lifting mechanism is hinged to the robotic arm and only needs to provide vertical tension and thrust; the bending moment is shared by the guide rails and the slider. The front end of the robotic arm is equipped with a lifting part for lifting the sterilization cart.

[0025] The lifting mechanism can use a pneumatic cylinder, an electric cylinder, an electric actuator, a linear motor, or a hydraulic cylinder. Using an electric actuator (32mm) results in a smaller size and simpler structure.

[0026] The lifting mechanism and robotic arm can be mounted on a mobile platform. The robotic arm moves with the mobile platform, and the lifting part moves with the robotic arm to approach the sterilization cart and inserts into the transfer slot of the sterilization tray in order to lift the sterilization cart.

[0027] Alternatively, the lifting part can be set as a movable part on the mechanical part. For example, the lifting part of the robotic arm can be a telescopic locking tongue 36; the locking tongue can be pushed out or pulled back by an electric push rod; or the locking tongue can be pushed out or pulled back by a cam mechanism in cooperation with a return spring.

[0028] The pushing motion of the pushing mechanism only needs to be slightly higher than the height of the sterilization tray; that is, between 1.1 and 1.5 times the height of the sterilization tray.

[0029] The height of the sterilization vehicle support frame can be kept to no more than 50 centimeters, making it a better match for the AGV used in the transfer sterilization vehicle. Example 2

[0030] The sterilization cart disassembly and assembly device in this embodiment has the same structure as the sterilization cart disassembly and assembly device in Embodiment 1; the difference lies in the operation process. The lifting mechanism inserts the lifting part of the lifting robotic arm into the transfer groove of the sterilization tray at the bottom of the sterilization cart, lifting the bottom sterilization tray. The lifting height should be greater than the height of one sterilization tray.

[0031] At this point, the dragging device sends the sterilization tray on the transfer rail into the sterilization cart support frame, and the lifting mechanism drives the robotic arm to descend, so that the upper sterilization tray is spliced ​​with the newly delivered sterilization tray; the lifting part moves backward to avoid hitting the support edge of the bottom sterilization tray, and then descends to the height corresponding to the transfer groove of the bottom sterilization tray; one splicing step is completed; the above splicing steps are repeated until the sterilization cart reaches the set number of layers. Example 3

[0032] The automated logistics transfer system for sterilization vehicles in this embodiment includes an AGV and a sterilization vehicle disassembly and assembly device. The AGV is equipped with a lifting tray that supports the sterilization vehicle. The sterilization vehicle disassembly and assembly device is the same as the one in Embodiment 1. The sterilization vehicle disassembly and assembly device is the same as the one in Embodiment 2.

[0033] Sterilization trays on the production line transfer track are pushed onto the sterilization cart support frame by a towing mechanism; the sterilization cart splicing device splices the carts layer by layer to assemble them into sterilization carts; the AGV enters the sterilization cart support frame from the front and uses a lifting plate to lift the sterilization cart to be sterilized; the sterilization cart can be remotely controlled by the operator or transported to the sterilization cart shelf in the transfer warehouse through the navigation program inside the AGV.

[0034] After sterilization, the AGV uses a lifting tray to lift the sterilized cart from the shelf (not shown in the figure). The operator can remotely control the AGV or use the navigation program inside the AGV to carry the sterilized cart to the sterilized cart support frame of the sterilized cart disassembly and assembly device, and the cart enters the sterilized cart support frame from the front. The lifting tray slowly descends, places the sterilized cart on the sterilized cart support frame, detaches from the sterilized cart, and exits the sterilized cart support frame, completing the transfer.

[0035] The sterilization cart disassembly and assembly device disassembles the sterilization cart layer by layer on the sterilization cart support frame and transfers it to the subsequent process via a transfer rail.

[0036] In this embodiment, the sterilization vehicle automatic logistics transfer system has a relatively low sterilization vehicle support frame in the sterilization vehicle disassembly and assembly device, which is no more than 50 cm, making it very suitable for using AGV to transfer sterilization vehicles; moreover, the disassembly and assembly efficiency is high.

[0037] The above examples are only used to illustrate this utility model. In addition, there are many other different implementation methods, which can be conceived by those skilled in the art after understanding the concept of this utility model. Therefore, they will not be listed one by one here.
