Description

Technical Field

[0001] This utility model belongs to the field of material storage technology, specifically a stacking device for an irradiation sterilization box. Background Technology

[0002] Irradiation sterilization refers to a method of sterilization using nuclear radiation. Compared with traditional sterilization methods, irradiation sterilization has advantages such as thorough sterilization, non-toxicity, no residue, fast speed, and safety and environmental friendliness. Irradiation sterilization equipment is set up as a circulating production line and transported on a track by cable traction. During the sterilization process, materials to be sterilized need to be placed in specially designed sterilization boxes. However, due to the high cost of radiation sources, each sterilization requires processing as many products as possible. Furthermore, the half-life of radiation sources is generally around 5-6 years. Therefore, when loading materials, it is necessary not only to process materials from multiple sterilization boxes simultaneously but also to minimize material transportation costs and increase the sterilization rate. However, current problems include the large size of the sterilization boxes, making stacking by hoisting or other methods very inefficient and slow, and difficult to stack accurately, resulting in inconvenience. Therefore, a faster and more accurate stacking device is proposed to solve these problems. Utility Model Content

[0003] To address the above problems, this utility model provides a stacking device for irradiation sterilization boxes, which solves the problems of slow stacking speed and inaccurate positioning of irradiation sterilization boxes.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A stacking device for an irradiation sterilization box includes a conveyor, a lifting frame, and a transport rack. The lifting frame is located between the conveyor and the transport rack. The bottom plates of the upper and lower layers of the transport rack are detachably equipped with limiting pins for limiting the sterilization box.

[0006] The conveyor is equipped with a first pushing component that pushes the disinfection box into the lifting frame or the lower layer of the transport rack;

[0007] The lifting frame is movably mounted on the support frame, which is equipped with a lifting mechanism that drives the lifting frame to move up and down; the support frame is also equipped with a second pushing component that pushes the lifted disinfection box to the upper layer of the transport rack.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the limiting pin can block and limit the disinfection box when it is pushed onto the transport rack, thus enabling the disinfection box to be pushed to the accurate position quickly; the conveyor can continuously transport the disinfection box filled with materials. When it is transported to the end of the conveyor, the first pushing component can be activated to push the disinfection box into the lower layer of the lifting frame or transport rack. After the disinfection box is pushed into the lifting frame, it can be lifted to the same level as the upper layer of the transport rack by the lifting mechanism. Then, the second pushing component pushes it into the upper layer of the transport rack, thereby speeding up the efficiency of transferring and stacking the disinfection box on the transport rack, which is faster than the traditional hoisting method.

[0009] As a further improvement to the above scheme, several first guide wheel sets are provided on the bottom of the lifting frame, and several second guide wheel sets are also provided on the side wall.

[0010] The bottom of the lifting frame is provided with a clearance opening to facilitate the movement of the first material pushing component.

[0011] The improved technology has the following effect: the first guide wheel group and the second guide wheel group can guide the disinfection box pushed into the lifting frame, preventing the disinfection box from getting stuck in the lifting frame.

[0012] As a further improvement to the above solution, the conveying components are arranged symmetrically at the front and rear, and the first pushing component is fixedly arranged in the middle of the interval between the front and rear conveying components.

[0013] The first pushing assembly includes a cylinder, a push block is fixedly installed at the end of the cylinder's output shaft, a push plate is rotatably installed at the upper end of the push block, a blocking boss is provided on the side of the push block to prevent the push plate box cylinder from flipping over, and a torsion spring is provided between the push plate and the push block.

[0014] The improved technology has the following effects: when the disinfection box is being transported in the conveyor, it can smoothly press down on the pusher plate, thereby reducing the chance of the pusher plate smoothly entering the lifting frame. After the disinfection box passes the pusher plate, it can tilt upward under the drive of the torsion spring, and then the pusher plate can be driven by the cylinder to push the disinfection box to move, thereby realizing the rapid pushing of the disinfection box.

[0015] As a further improvement to the above solution, a guide assembly is fixedly installed at the bottom of the conveyor and the support frame. The guide assembly has an upward-opening chute inside, and several first rollers and second rollers that rotatably contact the push block are installed inside the chute.

[0016] The technical effects of the above improvements are as follows: the guide assembly mainly keeps the push block moving in a straight line when it extends, and the first roller and the second roller are used to reduce friction with the guide assembly.

[0017] As a further improvement to the above solution, the conveying component includes a side plate, on which a transmission wheel and a guide wheel are rotatably mounted.

[0018] The improved technology has the following effects: the transmission wheel uses a chain drive to support the disinfection box during transmission, and the guide wheel contacts the side of the disinfection box to prevent the disinfection box from deflecting during transmission.

[0019] As a further improvement to the above solution, the bottom of the transport rack is equipped with limit wheels, which move within the guide rail.

[0020] The improved technology has the following effect: the guide rail guides and limits the limit wheel, preventing swaying and shaking during transportation. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0027] like Figure 1-4As shown, the specific solution of this embodiment is: a stacking device for an irradiation sterilization box, including a conveyor 10, a lifting frame 11, and a transport rack 12. The lifting frame 11 is located between the conveyor 10 and the transport rack 12. Specifically, the transport rack 12 is suspended on a top transport rail, and then transported to the position of the radiation source for irradiation sterilization via the transport rail. Figure 1 As shown, the transport rack 12 moves from the inside out and is perpendicular to the transport direction of the conveyor 10. The bottom plates of the upper and lower layers of the transport rack 12 are detachably equipped with limiting pins 121 for limiting the disinfection box. In this embodiment, the transport rack 12 is set with an upper and lower layer structure. The structure of the transport rack 12 can be arranged according to the actual situation. When the transport rack 12 is close to the conveyor 10 and the lifting frame 11, one of the limiting pins 121 can be removed. The one removed is the one on the side close to the lifting frame 11. The other one can prevent the disinfection box from being sent into the transport rack 12. After the disinfection box is installed on the transport rack 12, the limiting pin 121 can be inserted into the transport rack 12 again to prevent the disinfection box from sliding on the transport rack 12, thereby ensuring the stability of the disinfection box on the transport rack 12.

[0028] The conveyor 10 is equipped with a first pushing component 13 that pushes the disinfection box into the lifting frame 11 or into the lower layer of the transport rack 12. The pushing direction of the first pushing component 13 is the same as the transmission direction of the conveyor 10. The conveyor 10 is symmetrically arranged front and back, and the first pushing component 13 is fixedly arranged in the middle of the interval between the front and rear conveyor 10. Specifically, the conveyor 10 includes a side plate 101, on which a transmission wheel 102 and a guide wheel 103 are rotatably arranged. The transmission wheels 102 are driven by a sprocket and chain structure, and rubber that can provide better friction is also provided on the surface of the transmission wheel 102.

[0029] The lifting frame 11 is movably mounted on the support frame 14. The support frame 14 is equipped with a lifting mechanism that drives the lifting frame 11 to move up and down. Specifically, the support frame 14 is equipped with guide wheels (not shown in the attached drawings) to facilitate the vertical movement of the lifting frame 11. In this application, the lifting mechanism is a hydraulic cylinder mounted on the top of the support frame 14; the output end of the hydraulic cylinder is fixedly mounted to the top of the lifting frame 11. The support frame 14 is also equipped with a second pushing assembly 15 to push the lifted disinfection box to the upper layer of the transport rack 12. Specifically, the second pushing assembly 15 is a pneumatic cylinder, such as... Figure 1As shown, when the disinfection box containing materials comes into contact with the lifting frame 11 under the conveying of the conveyor 10, it can be pushed from the lifting frame 11 to the lower layer of the transport rack 12 under the push of the first pushing component 13. After the disinfection box is stacked on the lower layer of the transport rack 12, the first pushing component 13 is controlled to push the disinfection box onto the lifting frame 11 and then retracts. Then, by activating the lifting mechanism connected to the support frame 14, the disinfection box can be lifted to a position level with the upper layer of the transport rack 12. Then, under the push of the second pushing component 15, the disinfection box is pushed into the transport rack 12 for placement. Compared with the hoisting and transfer method, this method is more accurate in positioning, can improve stacking efficiency, and save time.

[0030] like Figure 4 As shown, in a preferred embodiment, the lifting frame 11 is provided with a plurality of first guide wheel groups 111 on its bottom and a plurality of second guide wheel groups 112 on its side wall; the bottom of the lifting frame 11 is provided with an avoidance opening 113 to facilitate the movement of the first pushing component 13. The avoidance opening 113 can facilitate the first pushing component 13 to avoid interference with the lifting frame 11 when pushing the disinfection box, and under the guidance of the first guide wheel group 111 and the second guide wheel group 112, the disinfection box can be pushed more flexibly.

[0031] like Figure 3 , 4 As shown, the first pushing assembly 13 includes a cylinder 131. A push block 132 is fixedly mounted on the output shaft end of the cylinder 131. A push plate 133 is rotatably mounted on the upper end of the push block 132. A blocking boss 134 is provided on the side of the push block 132 to prevent the push plate 133 from flipping against the cylinder 131. A torsion spring 135 is provided between the push plate 133 and the push block 132. In actual use, as the conveyor 10 transports the disinfection box to the lifting frame 11, the push plate 133 will move against the disinfection box. When they come into contact with each other, the pusher plate 133 will flip downwards, allowing the disinfection box to be transported normally to one side of the box lifting frame 11. After passing the pusher plate 133, the pusher plate 133 will bounce upwards under the push of the torsion spring 135. At this time, the cylinder 131 will be activated, and the cylinder 131 will push the pusher plate 133 to contact the disinfection box. Under the obstruction of the blocking boss 134, the pusher plate 133 can be kept in a vertical state, thereby pushing the disinfection box towards the lifting frame 11 and the transport rack 12.

[0032] As a preferred embodiment of the above, a guide assembly 16 is fixedly provided at the bottom of the conveyor 10 and the support frame 14. The guide assembly 16 is provided with an upward-opening slide groove 161. Several first rollers 162 and second rollers 163 are rotatably arranged in the slide groove 161 and in contact with each other. Through the first rollers 162 and second rollers 163, the push block 132 can smoothly reciprocate along the straight line of the slide groove 161, thereby reducing the friction between it and the guide assembly 16.

[0033] like Figure 1 As shown, in a preferred embodiment, the bottom of the transport rack 12 is provided with a limiting wheel 122. The limiting wheel 122 moves within the guide rail 17. The guide rail 17 can restrict the bottom of the transport rack 12 to prevent the transport rack 12 from shaking when the disinfection box is loaded.
