Background Art

[0002] During the loading and transportation of sterilization trays, for special infusion sterilization trays, the sterilization tray at the top of the stack is required not to be loaded with products. This will result in the direct release of one of the empty sterilization trays during transportation, which may cause the shutdown of the previous station or the stacking of materials at the subsequent station.

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Unless otherwise defined, the technical terms or scientific terms used in the present application shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance. Words such as "connected" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly. The embodiments of the present application disclose a high-speed sterilization tray loading system and a control method thereof.

[0056] The core of the present invention is to provide a high-speed sterilization tray loading system.

[0057] Another core of the present invention is to provide a control method for a high-speed sterilization tray loading system, which is applied to the above-mentioned high-speed sterilization tray loading system.

[0058] Please refer to Figures 1 to 3 . Figure 3 The middle plate lifting mechanism A is the first plate lifting mechanism 3 , and the plate lifting mechanism B is the second plate lifting mechanism 4 .

[0059] The high-speed sterilization tray loading system provided by the present invention includes a front conveying station 1, a rear conveying station 2, a first tray lifting mechanism 3, a second tray lifting mechanism 4 and a tray loading robot 5. The front conveying station 1 is used to convey an empty sterilization tray toward the loading station, and the rear conveying station 2 is used to continue to convey the loaded sterilization tray to the subsequent station. The second tray lifting mechanism 4 is arranged between the front conveying station 1 and the rear conveying station 2. The second tray lifting mechanism 4 is used to convey the sterilization tray to the rear conveying station 2. The first tray lifting mechanism 3 is arranged between the front conveying station 1 and the rear conveying station 2, and the first tray lifting mechanism 3 is located below the second tray lifting mechanism 4. The first tray lifting mechanism 3 is used to convey the sterilization tray to the rear conveying station 2 or the second tray lifting mechanism 4. The tray loading robot 5 is used to load the sterilization tray on the first tray lifting mechanism 3 or the sterilization tray on the second tray lifting mechanism 4.

[0060] Specifically, the front output station 1 and the rear conveying station 2 are respectively arranged at the two ends of the system and connected to the external conveying station. The first tray lifting mechanism 3 and the second tray lifting mechanism 4 are arranged in an upper and lower staggered manner. The second tray lifting mechanism 4 is arranged between the front conveying station 1 and the rear conveying station 2, and is used to transport the sterilization tray of the front conveying station 1 to the rear conveying station 2, and when passing the loading station, the sterilization tray in the second tray lifting mechanism 4 is loaded with the help of the tray loading robot 5. During the loading and conveying process of the second tray lifting mechanism 4, the first tray lifting mechanism 3 moves to the front conveying station 1 and waits for a new empty sterilization tray to be delivered. When a new sterilization tray needs to be loaded, the first tray lifting mechanism 3 moves the new sterilization tray to the loading station and waits until the second tray lifting mechanism 4 is loaded. When the new sterilization tray does not need to be loaded, the first tray lifting mechanism 3 directly moves the new sterilization tray to the rear conveying station 2. When the second tray lifting mechanism 4 returns after conveying and the first tray lifting mechanism 3 is loading, the second tray lifting mechanism 4 tracks and synchronizes with the first tray lifting mechanism 3, stops the tray loading robot 5 and controls the first tray lifting mechanism 3 to move the loaded sterilization tray to the second tray lifting mechanism 4 to continue loading, and then the first tray lifting mechanism 3 will continue to return to the front conveying station 1 to wait for the arrival of the new sterilization tray.

[0061] It should be noted that when determining whether the new sterilization tray delivered from the front conveying station 1 needs to be loaded, it is necessary to consider whether the specified requirements have been met after the rear conveying station 2 has delivered the last sterilization tray that does not need to be loaded and how many fully loaded sterilization trays have been delivered. At the same time, it is necessary to determine whether there is a sterilization tray being loaded on the second tray lifting mechanism 4, and whether the sterilization tray can be loaded and delivered to the rear conveying station 2 before it is delivered to the rear conveying station 2 by the first tray lifting mechanism 3.

[0062] In the above-mentioned high-speed sterilization tray loading system, the first tray lifting mechanism 3 and the second tray lifting mechanism 4 are installed in an upper and lower staggered manner, and the tray loading robot 5 can load at both the upper and lower levels. When loading the sterilization tray of the second tray lifting mechanism 4, the first tray lifting mechanism 3 prepares an empty tray in advance and waits. After the sterilization tray of the second tray lifting mechanism 4 is fully loaded and transported to the rear transport station 2, the first tray lifting mechanism 3 can be moved to the loading station and cooperate with the tray loading robot 5 for loading. After the second tray lifting mechanism 4 returns, the first tray lifting mechanism 3 transfers the loaded sterilization tray to the second tray lifting mechanism 4 for loading. After the transfer is completed, the first tray lifting mechanism 3 starts to return to the empty tray area at high speed to receive the empty tray. The present application solves the problem of tray changing gaps and the speed not keeping up when changing trays. At the same time, it provides a set of seamless tray changing solutions when a specific tray is not loaded, and solves the problem of material blocking and shutdown when emptying the tray.

[0063] The high-speed sterilization tray loading system provided by the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0064] In a specific embodiment, reference Figure 1 and Figure 2 The front conveying station 1, the second tray lifting mechanism 4 and the rear conveying station 2 are all clamped on two opposite sides of the same group of the sterilization tray, and the first tray lifting mechanism 3 is clamped on two opposite sides of another group of the sterilization tray.

[0065] Specifically, taking the plane diagram of the sterilization tray as an example, its upper and lower surfaces are the first group of clamping surfaces, and its left and right surfaces are the second group of clamping surfaces. During the conveying process, the front conveying station 1, the second tray lifting mechanism 4 and the rear conveying station 2 are all clamped on the first group of clamping surfaces of the sterilization tray, and the first tray lifting mechanism 3 is clamped on the second group of clamping surfaces of the sterilization tray. Furthermore, during the process of exchanging trays between the first tray lifting mechanism 3 and the second tray lifting mechanism 4, after the second tray lifting mechanism 4 is clamped on the first group of clamping surfaces, the first tray lifting mechanism 3 is controlled to release the clamping of the second group of clamping surfaces, thereby realizing the tray changing operation between the two tray lifting mechanisms.

[0066] Based on any of the above embodiments, Figure 1 and Figure 2 The second tray lifting mechanism 4 includes a frame 41, a second tray lifting assembly 42 and a second driving assembly. The frame 41 is arranged between the front conveying station 1 and the rear conveying station 2. The second tray lifting assembly 42 is slidably arranged on the frame 41, and is used to transport the sterilization tray from the front conveying station 1 to the rear conveying station 2. The second driving assembly is used to drive the second tray lifting assembly 42 to move along the frame 41.

[0067] Specifically, the frame 41 is fixedly arranged between the front conveying station 1 and the rear conveying station 2, the second tray lifting assembly 42 is arranged on the frame 41, and the conveying plane of the second tray lifting assembly 42 is level with the conveying planes of the front conveying station 1 and the rear conveying station 2, and the second driving assembly is used to drive the second tray lifting assembly 42 to move along the frame 41, and then travel between the front conveying station 1, the loading station and the rear conveying station 2, wherein the loading station is a station located below the tray loading robot 5, which is convenient for the tray loading robot 5 to load. It should be noted that the specific structure of the second tray lifting assembly 42 is the prior art, including how to load, how to transport from the front conveying station 1 to the second tray lifting assembly 42, and how to transport from the second tray lifting assembly 42 to the rear conveying station 2, which are all prior art and will not be repeated again.

[0068] Furthermore, the second driving component includes a second electric cylinder 43 and a second motor 44. The second electric cylinder 43 is arranged on the frame 41, and the second electric cylinder 43 is connected to the second plate lifting component 42. The second motor 44 is arranged on the frame 41, and the second motor 44 is used to drive the second electric cylinder 43 to drive the second plate lifting component 42 to move along the frame 41.

[0069] Specifically, the second motor 44 and the second electric cylinder 43 are provided with a transmission assembly, which can be any transmission method such as gear transmission. By controlling the second motor 44 to work, the second electric cylinder 43 is driven to move along the conveying direction of the frame 41. There are two second electric cylinders 43 and they are located on both sides of the frame 41. The second motor 44 is arranged on one side of one of the second electric cylinders 43, and the second motor 44 is rotatably connected to the other second electric cylinder 43 through a connecting shaft device, so as to realize the synchronous movement of the two second electric cylinders 43 and increase the stability of the second plate lifting assembly 42 during the movement.

[0070] Based on any of the above embodiments, Figure 1 and Figure 2 The first tray lifting mechanism 3 includes a slide rail 31, a first tray lifting assembly 32, a lifting assembly 34 and a first driving assembly. The slide rail 31 is arranged below the frame 41. The first tray lifting assembly 32 is slidably arranged on the slide rail 31, and is used to transport the sterilization tray from the front conveying station 1 to the rear conveying station 2 or the second tray lifting assembly 42. The lifting assembly 34 is arranged between the first tray lifting assembly 32 and the slide rail 31, and is used to drive the first tray lifting assembly 32 to rise and fall. The first driving assembly is used to drive the first tray lifting assembly 32 to move along the slide rail 31.

[0071] Specifically, the slide rail 31 is arranged in the middle part below the frame 41. Compared with the frame 41 being arranged between the end of the front conveying station 1 and the front end of the rear conveying station 2, the slide rail 31 is arranged between the front end of the sterilization tray at the end of the front conveying station 1 and the front end of the rear conveying station 2, thereby realizing that the first tray lifting assembly 32 is carried out from bottom to top in the process of taking and delivering trays between the front conveying station 1, the second tray lifting assembly 42 and the rear conveying station 2, and the first tray lifting assembly 32 is lifted by the lifting assembly 34 to complete the receiving, changing and delivering of the sterilization tray. The difference between the first tray lifting assembly 32 and the second tray lifting assembly 42 is that the two have different clamping positions for the sterilization tray, thereby ensuring smooth operation during the receiving and changing of the trays. Different from the second tray lifting mechanism 4, the first tray lifting mechanism 3 is provided with a lifting component for raising or lowering the first tray lifting component 32 to ensure that the operations of receiving, changing and delivering trays can be better completed. The lifting component can adopt a lifting cylinder or other structures with lifting function.

[0072] Furthermore, the first driving component includes a first electric cylinder 33 and a first motor 35. The first electric cylinder 33 is arranged on the slide rail 31. The first electric cylinder 33 is connected to the first plate lifting component 32. The first motor 35 is arranged on the slide rail 31, and the first motor 35 is used to drive the first electric cylinder 33 to drive the first plate lifting component 32 to move along the slide rail 31.

[0073] Specifically, the first electric cylinder 33 is arranged in the middle of the slide rail 31, the output end of the first electric cylinder 33 is connected to the first plate lifting assembly 32, and the first motor 35 is arranged on one side of the first electric cylinder 33 to drive the first electric cylinder 33 to move back and forth. The transmission between the first motor 35 and the first electric cylinder 33 can be achieved by gear transmission or other transmission methods.

[0074] refer to Figures 1 to 3 .

[0075] The control method of the high-speed sterilization tray loading system provided by the present invention is applied to the above-mentioned high-speed sterilization tray loading system, wherein the control method comprises:

[0076] Control the front conveying station 1 to convey the empty sterilization tray toward the first tray lifting mechanism 3 and the second tray lifting mechanism 3;

[0077] Determine whether the empty sterilization tray delivered to the end of the front delivery station 1 needs to be loaded;

[0078] If the empty sterilization tray transported to the end of the front transport station 1 needs to be loaded, determine whether the second tray lifting mechanism 4 is in the loading station. If the second tray lifting mechanism 4 is in the loading station, control the second tray lifting mechanism 4 to transport the empty sterilization tray to the bottom of the tray loading robot 5, and control the tray loading robot 5 to load the sterilization tray in the second tray lifting mechanism 4, and control the second tray lifting mechanism 4 to transport the sterilization tray to the rear transport station 2 after the loading is completed. If the second tray lifting mechanism 4 is not in the loading station, control the first tray lifting mechanism 3 to transport the empty sterilization tray to the bottom of the tray loading robot 5, and control the tray loading robot 5 to load the sterilization tray in the first tray lifting mechanism 3;

[0079] If the empty sterilization tray delivered to the end of the front delivery station 1 does not need to be loaded, the first tray lifting mechanism 3 is controlled to deliver the empty sterilization tray to the rear delivery station 2;

[0080] Determine whether the first tray lifting mechanism 3 is being loaded during the process of the second tray lifting mechanism 4 returning from the rear conveying station 2. If the first tray lifting mechanism 3 is being loaded, control the second tray lifting mechanism 4 to track and exchange trays with the first tray lifting mechanism 3. If the first tray lifting mechanism 3 is not being loaded, control the second tray lifting mechanism 4 to wait for a new empty sterilization tray to be delivered.

[0081] Specifically, using the process Figure 3 To explain, first the system performs zeroing of the whole machine. After the zeroing operation, each station is in standby state, and the empty sterilization tray is transported to the end of the front transport station 1 through the front transport station 1, and the empty sterilization tray is clamped by the first tray lifting mechanism 3 and transported to the loading station (if it is the first empty sterilization tray just started by the system, it can be directly transported to the loading station by the second tray lifting mechanism 4 and loaded by the tray loading robot 5), and it is judged whether the empty sterilization tray needs to be loaded with products. If the sterilization tray does not need to be loaded with products, the first tray lifting mechanism 3 is controlled to directly transport it to the rear transport station 2. If the sterilization tray needs to be loaded with products, it continues to judge whether the second tray lifting mechanism 4 is loading. If the second tray lifting mechanism 4 is loading, the first tray lifting mechanism The tray loading robot 5 is stopped at the moment when the first tray lifting mechanism 3 is stopped, and the first tray lifting mechanism 3 is controlled to transport the loaded sterilization tray to the second tray lifting mechanism 4, and then the tray loading robot 5 is controlled to continue loading the sterilization tray on the second tray lifting mechanism 4. At this moment, the first tray lifting mechanism 3 returns to the front conveying station 1 to take the new sterilization tray and judge whether the product needs to be loaded, and so on.

[0082] The control method of the high-speed sterilization tray loading system achieves seamless handover between the two tray lifting mechanisms and directly delivers empty trays that do not need to be loaded to the rear end without affecting the loading process, thereby solving the problem of tray changing gaps and speed failure when changing trays.

[0083] Based on any of the above embodiments, the specific steps of the second tray lifting mechanism 4 tracking and changing the tray include:

[0084] Control the second tray lifting mechanism 4 to move to the top of the first tray lifting mechanism 3 and synchronously control the tray loading robot 5 to stop loading;

[0085] The first tray lifting mechanism 3 is controlled to drive the sterilization tray to rise to the second tray lifting mechanism 4 , and the tray is exchanged with the second tray lifting mechanism 4 .

[0086] Specifically, the second tray lifting mechanism 4 is controlled to track and synchronize with the first tray lifting mechanism 3 until the second tray lifting mechanism 4 moves to the top of the first tray lifting mechanism 3, and at the same time, the tray loading robot 5 is controlled to temporarily stop loading, and the lifting assembly in the first tray lifting mechanism 3 is used to realize the tray exchange between the first tray lifting mechanism 3 and the second tray lifting mechanism 4, and the second tray lifting mechanism 4 continues to load the unloaded sterilization trays.

[0087] It should be noted that if the sterilization tray on the first tray lifting mechanism 3 has been loaded during the tracking process of the second tray lifting mechanism 4, it is necessary to judge whether the subsequent sterilization tray of the front conveying station 1 is to be loaded. If loading is required, the first tray lifting mechanism 3 can directly transport the fully loaded sterilization tray from the lower conveying channel directly to the rear conveying station 2, and control the second tray lifting mechanism 4 to take the new empty tray from the front conveying station 1 and move it to the loading station for loading. If loading is not required, the tray exchange between the first tray lifting mechanism 3 and the second tray lifting mechanism 4 is still performed, and the first tray lifting mechanism 3 moves the sterilization tray that does not need to be loaded at the front conveying station 1 to the rear conveying station 2.

[0088] Based on any of the above embodiments, the control method also includes controlling the first tray lifting mechanism 3 to move to the front conveying station 1 after the second tray lifting mechanism 4 and the first tray lifting mechanism 3 complete the tray exchange, and again determining whether the empty sterilization tray transported to the end of the front conveying station 1 needs to be loaded.

[0089] Based on any of the above embodiments, the control method also includes controlling the entire loading system to slow down when one of the first tray lifting mechanism 3 or the second tray lifting mechanism 4 fails, and achieving loading and transportation of the sterilization tray by controlling the tray lifting mechanism that is not faulty.

[0090] Specifically, this state is the single tray lifting mechanism mode, and the faulty tray lifting mechanism is moved to other positions except the loading station. Since the two tray lifting mechanisms are installed in an up-and-down staggered manner, they do not interfere with each other during the transportation process. At the same time, the single tray lifting mechanism mode needs to cooperate with the overall system to reduce the speed to achieve the transfer of the sterilization tray. The advantage of this method is that during the repair of the faulty tray lifting mechanism, the normal operation of the tray lifting mechanism is not affected, ensuring the loading and transportation progress of the sterilization tray.

[0091] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0092] The above is a detailed introduction to a high-speed sterilization tray loading system and a control method thereof provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the present invention.
