Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment, and in particular to a tray cleaning and disinfection machine and method. Background Technology

[0002] An existing application with application number 202220926342.6 discloses an egg tray disinfection and cleaning machine for vaccine production, comprising: a tray feeding device for conveying egg trays into the egg tray disinfection and cleaning machine; a preliminary washing tank for preliminary cleaning of the egg trays; an immersion disinfection tank for immersing and disinfecting the egg trays; a disinfectant cleaning tank for cleaning the egg trays of disinfectant; a drying tank for drying the egg trays; and a collection device for collecting the disinfected egg trays. The tray feeding device, preliminary washing tank, immersion disinfection tank, disinfectant cleaning tank, drying tank, and collection device are arranged sequentially. The preliminary washing tank contains a cleaning conveyor belt, one end of which is connected to the tray feeding device, and the other end is connected to the immersion disinfection tank. The immersion disinfection tank contains an immersion disinfection belt, one end of which is connected to the preliminary washing tank, and the other end is connected to the disinfectant cleaning tank. The immersion disinfection belt is concave in the middle and higher at both ends. The drying tank contains a drying conveyor belt, one end of which is connected to a clean water cleaning tank, and the other end is connected to the collection device. The egg tray disinfection and cleaning machine used in vaccine production uses conveyor belts to transport egg trays during the cleaning, disinfection and drying process. On the one hand, tray jamming is prone to occur at the junctions of the conveyor belts, affecting production efficiency. On the other hand, the conveyor belts occupy a lot of space, are inconvenient to arrange, and are costly. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a plate cleaning and disinfection machine that occupies little space, is easy to arrange, has a compact structure, low cost, prevents plate jamming, and has high production efficiency; it also provides a plate cleaning and disinfection method that prevents plate jamming and improves production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A tray cleaning and disinfection machine includes a tray feeding device, a cleaning and disinfection device, and a tray discharging device arranged in sequence. The cleaning and disinfection device includes multiple processing boxes arranged side by side. Each processing box is equipped with a circulating tray conveying mechanism with parallel vertical running trajectories. The circulating tray conveying mechanism is equipped with multiple tray positioning mechanisms arranged at intervals along the conveying direction. Each processing box is equipped with a tray pushing device above it. The tray pushing device is used to push the trays on the circulating tray conveying mechanism in the front processing box to the tray positioning mechanisms on the circulating tray conveying mechanism in the rear processing box, and to push the trays on the circulating tray conveying mechanism in the rearmost processing box to the tray discharging device.

[0006] As a further improvement to the above technical solution:

[0007] The circulating tray conveying mechanism includes a rotating frame and a rotation drive assembly for driving the rotating frame to rotate, and each of the tray positioning mechanisms is respectively arranged around the rotating frame.

[0008] The disc positioning mechanism includes a disc support assembly and a limiting assembly both mounted on a rotating frame. A disc placement area is formed between the disc support assembly and the limiting assembly, allowing the disc to enter and exit. Elastic disc baffle assemblies that can rotate forward to avoid the disc are respectively provided at the four corners of the disc placement area.

[0009] The elastic baffle assembly includes a stop block, an elastic element, and a one-way limiting element. The stop block is rotatably mounted on a rotating frame, the elastic element is located between the stop block and the rotating frame, and the one-way limiting element is located on the rotating frame and limited to the rear side of the stop block.

[0010] The forward and backward movement of the trays in the tray placement area is parallel to the rotation axis of the rotating frame.

[0011] The rotating frames inside each of the aforementioned processing boxes are coaxially connected.

[0012] The rotating frame is cube-shaped.

[0013] The pusher device includes a translation frame that is translatably installed above each processing box and multiple sets of pusher components that can rotate forward to avoid the plate. Each set of pusher components is arranged at intervals on the translation frame and corresponds to each processing box.

[0014] The push plate assembly includes a push plate and a one-way limiting member. The push plate is rotatably mounted on the translation frame, and the one-way limiting member is located on the translation frame and is limited to the rear side of the push plate.

[0015] A method for cleaning and disinfecting a tray, using the aforementioned tray cleaning and disinfection machine, includes the following steps:

[0016] S1. The trays are first pushed sequentially by the tray feeding device to the tray positioning mechanism on the tray circulation conveying mechanism in the front processing box. The tray circulation conveying mechanism receives and delivers trays in a cyclic manner, so that the trays enter the processing box for corresponding processing.

[0017] S2. The disc body is then pushed from the disc body positioning mechanism on the disc body positioning mechanism of the circulating disc body in the pre-processing box to the disc body positioning mechanism on the circulating disc body in the post-processing box by the disc body pushing device, so that the disc body enters each processing box in sequence for processing.

[0018] S3. The tray is pushed from the tray positioning mechanism on the tray conveying mechanism in the rear processing box by the tray pushing device to the tray output device, and then output by the tray output device.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] The working process of the tray cleaning and disinfection machine of the present invention is as follows: First, the trays are pushed sequentially by the tray feeding device to the tray positioning mechanism on the circulating tray conveying mechanism in the front processing box. The circulating tray conveying mechanism circulates and receives trays, allowing the trays to enter the processing box for corresponding processing. Second, the trays are pushed from the tray positioning mechanism on the circulating tray conveying mechanism in the front processing box to the tray positioning mechanism on the circulating tray conveying mechanism in the rear processing box by the tray pushing device, allowing the trays to enter each processing box sequentially for processing (the circulating tray conveying mechanism in each processing box circulates and receives trays, conveying the trays from top to bottom into the processing box for processing, and then conveying the trays from bottom to top to the top of the processing box for output). Then, the trays are pushed from the tray positioning mechanism on the circulating tray conveying mechanism in the rear processing box by the tray pushing device to the tray output device, and then output by the tray output device. On the one hand, this tray cleaning and disinfection machine uses a circulating tray conveying mechanism with parallel vertical running trajectories to circulate the trays within each processing box, meeting the internal circulation processing requirements of the processing box. It occupies little space, is easy to arrange, and has low cost. On the other hand, the circulating tray conveying mechanisms of each processing box are pushed together by a tray pushing device to prevent tray jamming and improve production efficiency. Thirdly, the tray pushing device can push the trays on the circulating tray conveying mechanism in the pre-processing box to the tray positioning mechanism in the circulating tray conveying mechanism in the post-processing box, and push the trays on the circulating tray conveying mechanism in the last processing box to the tray dispensing device. This achieves simultaneous tray pushing between the circulating tray conveying mechanisms in each processing box and between the circulating tray conveying mechanism and the tray dispensing device in the last processing box, resulting in a compact structure and reasonable arrangement.

[0021] The tray cleaning and disinfection method of the present invention has the following advantages: First, the trays are circulated and transported within each processing box by a circulating tray conveying mechanism with parallel vertical running trajectories, which meets the internal circulation processing requirements of the processing box and is low in cost. Second, the circulating tray conveying mechanisms of each processing box are pushed by a tray pushing device to prevent tray jamming and improve production efficiency. Third, the tray pushing device can push the trays on the circulating tray conveying mechanism in the pre-processing box to the tray positioning mechanism on the circulating tray conveying mechanism in the post-processing box and push the trays on the circulating tray conveying mechanism in the last processing box to the tray dispensing device, realizing simultaneous tray pushing between the circulating tray conveying mechanisms in each processing box and between the circulating tray conveying mechanism and the tray dispensing device in the last processing box, further improving production efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Example 1:

[0037] Figures 1 to 8 An embodiment of the tray cleaning and disinfection machine of the present invention is shown. This embodiment includes a tray infeed device 1, a cleaning and disinfection device 2, and a tray discharge device 3 arranged sequentially. The cleaning and disinfection device 2 includes multiple processing boxes 21 arranged side-by-side. Each processing box 21 has a circulating tray conveying mechanism 4 with parallel vertical running paths. The circulating tray conveying mechanism 4 has multiple tray positioning mechanisms 5 arranged at intervals along the conveying direction. Each processing box 21 has a tray pushing device 6 above it. The tray pushing device 6 is used to push the trays 7 on the circulating tray conveying mechanism 4 in the pre-processing box 21 to the tray positioning mechanisms 5 on the circulating tray conveying mechanism 4 in the post-processing box 21, and to push the trays 7 on the circulating tray conveying mechanism 4 in the last processing box 21 to the tray discharge device 3. The pre-processing box 21 is closer to the tray infeed device 1 than the post-processing box 21.

[0038] The working process of this tray cleaning and disinfection machine is as follows: First, the trays are pushed sequentially by the tray feeding device 1 to the tray positioning mechanism 5 on the tray circulation conveying mechanism 4 inside the front processing box 21. The tray circulation conveying mechanism 4 circulates and receives trays, allowing the trays 7 to enter the processing box 21 for corresponding processing. Second, the trays are pushed from the tray positioning mechanism 5 on the tray circulation conveying mechanism 4 inside the front processing box 21 to the tray positioning mechanism 5 on the tray circulation conveying mechanism 4 inside the rear processing box 21 by the tray pushing device 6, allowing the trays 7 to enter each processing box 21 sequentially for processing (the tray circulation conveying mechanism 4 inside each processing box 21 circulates and receives trays, conveying the trays 7 from top to bottom into the processing box 21 for processing, and then conveying the trays 7 from bottom to top to the top of the processing box 21 for output). Then, the trays are pushed from the tray positioning mechanism 5 on the tray circulation conveying mechanism 4 inside the rear processing box 21 by the tray pushing device 6 to the tray output device 3, and then output by the tray output device 3. On the one hand, in this tray cleaning and disinfection machine, the trays 7 are circulated and transported within each processing box 21 by a circulating tray conveying mechanism 4 arranged in parallel with the vertical running trajectory, which meets the internal circulation processing requirements of the processing box 21, occupies little space, is easy to arrange, and has low cost. On the other hand, the circulating tray conveying mechanisms 4 of each processing box 21 are pushed by a tray pushing device 6 to prevent tray jamming and improve production efficiency. Thirdly, the tray pushing device 6 can push the trays 7 on the circulating tray conveying mechanism 4 in the pre-processing box 21 to the tray positioning mechanism 5 on the circulating tray conveying mechanism 4 in the post-processing box 21 and push the trays 7 on the circulating tray conveying mechanism 4 in the last processing box 21 to the tray dispensing device 3, realizing simultaneous tray pushing between the circulating tray conveying mechanisms 4 in each processing box 21 and between the circulating tray conveying mechanism 4 and the tray dispensing device 3 in the last processing box 21, with a compact structure and reasonable arrangement.

[0039] Furthermore, the processing tank 21 contains processing liquid, and the circulating conveying mechanism 4 can transport the disc 7 from top to bottom into the processing liquid for processing. In actual use, the liquid level of the processing liquid is lower than the rotation center of the circulating conveying mechanism 4.

[0040] Furthermore, in this embodiment, the circulating tray conveying mechanism 4 includes a rotating frame 41 and a rotating drive assembly 42 for driving the rotating frame 41 to rotate. Each tray positioning mechanism 5 is respectively arranged around the rotating frame 41. The rotating drive assembly 42 drives the rotating frame 41 to rotate, causing the tray positioning mechanism 5 to move cyclically around the rotation center of the rotating frame 41, thereby realizing the cyclic conveying of the tray 7.

[0041] Furthermore, in this embodiment, as Figure 3 and Figure 5As shown, the disc positioning mechanism 5 includes a disc support assembly 51 and a limiting assembly 52 both mounted on the rotating frame 41. A disc placement area 53 is formed between the disc support assembly 51 and the limiting assembly 52, which allows the disc 7 to enter and exit. At the four corners of the disc placement area 53, there are elastic baffle assemblies 54 that can rotate forward (in front of the disc 7 conveying direction) to avoid the disc 7. The tray placement area 53 has an inlet on the rear side and an outlet on the front side in the conveying direction of the tray body 7. The tray body 7 enters the tray placement area 53 through the inlet. During the entry process, it pushes the elastic baffle assemblies 54 on both sides of the inlet to rotate forward. After fully entering, the elastic baffle assemblies 54 on both sides of the inlet are reset under the action of elastic restoring force. The tray body 7 is blocked and limited by the elastic baffle assemblies 54 at the four corners of the tray placement area 53. The tray body 7 moves out of the tray placement area 53 through the outlet. During the movement out, it pushes the elastic baffle assemblies 54 on both sides of the outlet to rotate forward. After fully moving out, the elastic baffle assemblies 54 on both sides of the outlet are reset under the action of elastic restoring force.

[0042] Furthermore, such as Figure 4 and Figure 6 As shown, in this embodiment, the elastic baffle assembly 54 includes a stop block 541, an elastic element 542, and a one-way limiting element 543. The stop block 541 is rotatably mounted on the rotating frame 41. The elastic element 542 is located between the stop block 541 and the rotating frame 41. The one-way limiting element 543 is located on the rotating frame 41 and is positioned behind the stop block 541. Under the elastic force of the elastic element 542, the stop block 541 abuts against the one-way limiting element 543. Under the limiting action of the one-way limiting element 543, it cannot rotate backward but can only rotate upward. That is, without forward pushing action, the stop block 541 can be held in the position limited by the one-way limiting element 543, thus realizing the baffle. It not only has a simple structure but also meets the conveying requirements of the disc body 7.

[0043] Furthermore, in this embodiment, the front and rear inlet / outlet direction of the tray placement area 53 is parallel to the rotation axis of the rotating frame 41, which facilitates the tray body 7 entering and exiting the tray placement area 53.

[0044] Furthermore, in this embodiment, the rotating frames 41 in each processing box 21 are coaxially connected. In this way, each rotating frame 41 can be driven to rotate synchronously by a single rotating drive component 42, resulting in a simpler structure and lower cost.

[0045] Furthermore, in this embodiment, the rotating frame 41 is cubical. Each disc positioning mechanism 5 is respectively disposed on one of the four sides of the rotating frame 41. At least one disc positioning mechanism 5 is disposed on the first side of each rotating frame 41. The processing tank 21 contains processing liquid, the liquid level of which is lower than the rotation center of the rotating frame 41. This circulating disc conveying mechanism 4 can cyclically transport the discs 7 into the processing liquid and then output them from the processing liquid, and facilitates control of the processing time of the discs 7 in the processing liquid. A liquid level detection mechanism can be installed inside the processing tank 21 to facilitate precise control of the liquid level within the processing tank 21.

[0046] Furthermore, in this embodiment, as Figure 7 and Figure 8 As shown, the tray-pushing device 6 includes a translation frame 61 that is translatably mounted above each processing box 21, and multiple sets of tray-pushing assemblies 62 that can rotate forward (in the forward direction of the tray 7's conveying direction) to avoid obstructing the tray 7's forward conveying. Each set of tray-pushing assemblies 62 is arranged at intervals on the translation frame 61 and corresponds one-to-one with each processing box 21. When the tray 7 moves forward relative to the tray-pushing device 6, it can push the tray-pushing assemblies 62 forward, causing the assemblies 62 to rotate forward and avoid obstructing the forward conveying of the tray 7. When the tray-pushing device 6 is behind the tray 7, it can push the tray 7 forward. The structure is simple, enabling simultaneous pushing of multiple sets of trays 7 with high efficiency.

[0047] Further, in this embodiment, the pusher assembly 62 includes a pusher plate 621 and a one-way limiting member 622. The pusher plate 621 is rotatably mounted on the translation frame 61, and the one-way limiting member 622 is mounted on the translation frame 61 and limited to the rear side of the pusher plate 621. When the disc 7 moves forward relative to the pusher plate 621, it can push the pusher plate 621 forward, causing the pusher plate 621 to rotate forward to avoid obstructing the forward transport of the disc 7. When the pusher plate 621 pushes against the rear side of the disc 7, it will not rotate backward under the limiting effect of the one-way limiting member 622, and can move forward with the translation frame 61 to push the disc 7. Preferably, the pusher plate 621 hangs down under the action of gravity, and in the hanging state, it abuts against the one-way limiting member 622. Further, an elastic reset member can be provided between the pusher plate 621 and the translation frame 61, so that the pusher plate 621 is kept in the hanging state when no external force is applied.

[0048] Furthermore, in this embodiment, there are three processing boxes 21, each containing a cleaning mechanism, a disinfection mechanism, and a drying mechanism, respectively, to achieve a process of first cleaning, then disinfecting, and finally drying the disc 7. Of course, in other embodiments, there are three processing boxes 21, each containing a cleaning mechanism, an alkali mechanism, and a rinsing mechanism, respectively, to achieve a three-stage cleaning process for the disc 7. This embodiment does not impose a specific limit on the number of processing boxes 21; the number of processing boxes 21 and the internal processing mechanisms can be specifically set according to the processing needs of the disc 7.

[0049] Example 2:

[0050] A method for cleaning and disinfecting a tray, using the tray cleaning and disinfection machine of Example 1, includes the following steps:

[0051] S1. The tray is first pushed by the tray feeding device 1 to the tray positioning mechanism 5 on the tray conveying mechanism 4 in the front processing box 21. The tray conveying mechanism 4 receives and sends trays in a cycle, so that the tray 7 enters the processing box 21 for corresponding processing.

[0052] S2. The tray body is then pushed by the tray pushing device 6 from the tray body positioning mechanism 5 on the circulating tray conveying mechanism 4 in the pre-processing box 21 to the tray body positioning mechanism 5 on the circulating tray conveying mechanism 4 in the post-processing box 21, so that the tray body 7 enters each processing box 21 in sequence for processing (the circulating tray conveying mechanism 4 in each processing box 21 circulates receiving and sending trays, conveying the tray body 7 from top to bottom into the processing box 21 for processing, and then conveying the tray body 7 from bottom to top to the top of the processing box 21 for output).

[0053] S3. Finally, the tray is pushed from the tray positioning mechanism 5 on the tray circulation conveying mechanism 4 in the rear processing box 21 by the tray pushing device 6 to the tray output device 3, and then output by the tray output device 3.

[0054] This tray cleaning and disinfection method has several advantages. First, the trays 7 are circulated within each processing box 21 via a parallel, vertically aligned circulating tray conveying mechanism 4, meeting the internal circulatory processing requirements of the processing box 21 and achieving low cost. Second, the circulating tray conveying mechanisms 4 in each processing box 21 are pushed together by a tray pushing device 6 to prevent tray jamming and improve production efficiency. Third, the tray pushing device 6 can push the trays 7 on the circulating tray conveying mechanism 4 in the pre-processing box 21 to the tray positioning mechanism 5 on the circulating tray conveying mechanism 4 in the post-processing box 21, and push the trays 7 on the circulating tray conveying mechanism 4 in the last processing box 21 to the tray exiting device 3, achieving simultaneous tray pushing between the circulating tray conveying mechanisms 4 in each processing box 21 and between the circulating tray conveying mechanism 4 in the last processing box 21 and the tray exiting device 3, further improving production efficiency.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
