Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sterile article sorting, and particularly relates to a device for lossless sorting of sterile articles. BACKGROUND

[0002] Sterile articles refer to articles that are completely killed or removed of any surviving microorganisms after physical or chemical sterilization treatment. The most core and most direct importance of sterile articles is to prevent and control hospital infections. Sterile articles can also ensure the safety and success rate of medical operations. In addition to the medical field, in the production process of canned food and some dairy products, sterilization treatment and aseptic packaging technology are also used to kill microorganisms in products, so as to ensure food safety and prolong shelf life. Therefore, sterile articles must be packaged. After the sterile articles are sterilized, they need to be sorted and distributed.

[0003] In the Chinese patent with the publication number CN213825929U, a sterile sorting device for surgical instruments is mentioned. The device can separate instruments with different thicknesses by controlling the movement of the conveyor belt with the first motor, and can push the separated instruments out of the conveyor belt with the second motor. The device can smoothly guide the instruments pushed out of the conveyor belt into the corresponding box without causing damage to the surgical instruments.

[0004] The packaging of sterile articles is crucial for their contents. However, there are many types of sterile articles, and their weights vary greatly. When the sterile articles slide into the sorting box, the impact force generated by different weights of sterile articles is also different. At the same height difference, the impact force generated by the falling of lighter sterile articles is smaller than that of heavier sterile articles. In order to avoid damage to the packaging of heavier sterile articles during sliding into the box, the height difference between the box and the sorting device needs to be reduced. However, this will make it difficult for heavier sterile articles to smoothly slide into the box, thus affecting the packing of sterile articles. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a device for lossless sorting of sterile articles.

[0006] The technical solution adopted to solve the above technical problem is: A device for non-destructive sorting of sterile items includes a sorting machine and several collection boxes. Several sorting tables are respectively arranged on both sides of the sorting machine. The collection box is a box with one end open. Several collection boxes are respectively installed on several sorting tables, and the opening of the collection box faces the sorting machine. The top of the sorting table is inclined, and two electric push rods are provided on the top of the sorting table. The output ends of the two electric push rods are rotatably connected to a tray. The collection box is located inside the tray. The collection box is divided into a front section and a rear section. The front section has a groove, and a push plate is movably arranged in the groove. Baffles are fixedly arranged on both sides of the sorting table. The side walls of the two baffles are provided with a push mechanism for driving the push plate. The rear section has a through hole, through which a drive wheel and a driven wheel are rotatably connected. A conveyor belt is laid between the drive wheel and the driven wheel. The conveyor belt is flush with the side wall of the through hole. A rotating rod is fixedly installed on the side wall of the drive wheel. The rotating rod passes through the side wall of the collection box and is fixedly installed on a rotating disk. The side wall of the tray box is provided with a conveying mechanism for driving the rotating disk.

[0007] Through the above technical solution, this application can adjust the tilt of the collection box according to the different weights of sterile items, and can transport heavier sterile items to the depth of the collection box when the tilt is small, making it convenient to store sterile items.

[0008] Furthermore, the pushing mechanism includes a dual-axis motor, a drive gear, a front gear, a connecting gear, a rear gear, two extension rods, and two transmission gears. The dual-axis motor is fixedly mounted at the bottom of the tray. The two extension rods are respectively fixedly mounted at the two output ends of the dual-axis motor. The drive gear is fixedly mounted at the other end of the extension rod. The front gear, the connecting gear, and the two transmission gears are all rotatably connected to the side wall of the baffle. The drive gear meshes with one transmission gear, and the front gear meshes with the same transmission gear. The connecting gear is positioned between the two transmission gears and meshes with both transmission gears. The rear gear meshes with the other transmission gear. Connecting rods are eccentrically mounted on the side walls of both the front and rear gears, and the two connecting rods are rotatably connected to the side wall of the pushing plate.

[0009] Through the above technical solution, the start of the dual-axis motor will cause the extension rod to drive the drive gear to rotate, and the transmission gear, connecting gear, front gear and rear gear that mesh with it will rotate in succession. Since the connecting rods are eccentrically installed on the side walls of the front gear and the rear gear, the rotation of the front gear and the rear gear will drive the push plate to reciprocate, thereby sending the sterile items on the push plate to the conveyor belt.

[0010] Furthermore, the collection box has movable holes on both sides of its sidewalls, through which the connecting rod passes, and the end of the collection box facing the connecting rod is set at an angle.

[0011] With the above technical solution, since the connecting rod is fixedly set on the side wall of the front gear and the side wall of the rear gear, the connecting rod will make a circular motion during the rotation of the front gear and the rear gear. The push plate with connecting rods at both ends will make a reciprocating motion, not only in the horizontal direction but also in the vertical direction, thereby repeatedly transporting the sterile items on the push plate to the conveyor belt.

[0012] Furthermore, a side turntable is fixedly connected to the side wall of the rear gear. Two protruding rods are eccentrically installed on the side wall of the side turntable away from the rear gear. A translation rod is slidably connected to the side wall of the tray. A push rod is fixedly installed on the side wall of the translation rod. The side wall of the push rod abuts against the side wall of the protruding rod. A protrusion is fixedly installed on the side wall of the translation rod away from the push rod. A curved rod is rotatably connected to the side wall of the baffle. The curved rod is L-shaped. One end of the curved rod is located on the movement trajectory of the protruding rod. The other end of the curved rod has a movable slot. The protrusion is located inside the movable slot.

[0013] Through the above technical solution, the rotation of the rear gear will drive the side turntable to rotate, so the protruding rod on the side wall of the side turntable will rotate accordingly, thereby causing the curved rod and the push rod that are opposed to it to be pushed by the protruding rod in sequence. When the push rod is pushed, the push rod will drive the translation rod to move forward, and the rear protruding rod will leave the push rod. The protruding rod on the other side will push the curved rod to rotate, thereby causing the movable slot to drive the protrusion and the translation rod to move backward. Therefore, the translation rod will reciprocate in both the horizontal and vertical directions.

[0014] Furthermore, a sliding rod is fixedly provided on the side wall of the translation rod, and a sliding groove is provided on the side wall of the tray, with the sliding rod slidably connected to the inner wall of the sliding groove.

[0015] The above technical solution makes the translation of the sliding rod more stable by setting up the sliding rod and the sliding groove. In addition, the setting of the sliding rod can also leave a distance between the translation rod and the tray, so that the movement of the translation rod will not affect the rotation of the rear gear, connecting gear, etc.

[0016] Furthermore, the conveying mechanism includes a swing rod, a spindle plate, a long lever, a short lever, a ratchet, a drive rod, and a drive disk. The swing rod and the translation rod are movably arranged together. The swing rod is fixedly connected to the spindle plate. The middle position of the spindle plate is rotatably connected to the side wall of the tray. The long lever and the short lever are rotatably connected to the side walls at both ends of the spindle plate, respectively. The side wall of the ratchet is fixedly connected to the drive rod. The drive rod passes through the side wall of the tray and is fixedly connected to the side wall of the drive disk. The side walls of the long lever and the short lever abut against the side wall of the ratchet. The drive disk is movably connected to the rotating disk.

[0017] Through the above technical solution, the swing of the swing rod will cause the spindle plate to rotate, which in turn causes the long lever and the short lever to lock the ratchet in sequence. The ratchet is designed to rotate only in one direction, so the ratchet will drive the drive wheel to rotate in one direction. The conveyor belt laid on the drive wheel will then transport the sterile items pushed onto the conveyor belt to the depth of the collection box, making it convenient for the collection box to store the sterile items.

[0018] Furthermore, a short rod is fixedly connected to the side wall of the translation rod, and an arc-shaped plate is fixedly installed on the side wall of the swing rod, with the short rod abutting against the inner wall of the arc-shaped plate.

[0019] With the above technical solution, as the short rod moves forward following the translation rod, it will cause the arc plate and the swing rod to swing. When the short rod moves backward following the translation rod, since the spindle plate, which is fixedly connected to the swing rod, is inclined and the long lever is located at a high position, the swing rod will return to its initial position under the action of the counterweight after losing the thrust of the short rod. This makes it easier for the short rod to push the arc plate and the swing rod to swing again.

[0020] Furthermore, the bottom of the tray has two rotating holes, and both the rotating disk and the drive disk are located in the rotating holes. The side wall of the rotating disk has a vertical groove, and the side wall of the drive disk has a vertical rod fixedly installed, which is inserted into the vertical groove.

[0021] With the above technical solution, since the rotating disk is more prominent than the collection box, in order to meet the rotation requirements of the rotating disk, a rotating hole for rotation needs to be set at the bottom of the tray. The setting of the vertical rod and the vertical groove can also make the drive disk drive the rotating disk to rotate together, and it is also convenient to separate the drive disk and the rotating disk. Both ends of the vertical groove are open, and the design of the vertical rod also allows it to be inserted into the slot from either end.

[0022] Furthermore, the distance between the conveyor belt and the pusher plate is less than 5cm, and the height of the pusher plate is flush with that of the conveyor belt.

[0023] With the above technical solution, the distance between the conveyor belt and the pusher plate should be much smaller than the size of the sterile items to be transported. Therefore, after the pusher plate pushes the sterile items forward, the conveyor belt can seamlessly take over the task of transporting the sterile items. The fact that the conveyor belt and the pusher plate are flush when they are at their lowest position is also to better take over the sterile items. Then the sterile items will be sent to the rear of the collection box and stacked there.

[0024] Furthermore, the ratchet is located between the side turntable and the side wall of the tray, and both the long lever and the short lever are L-shaped, with the short sides of the long lever and the short sides of the short lever abutting against the side wall of the ratchet.

[0025] Through the above technical solution, the long lever and the short lever will sequentially actuate the ratchet, causing the ratchet to rotate in one direction. The rotation of the ratchet will then drive the drive wheel to rotate, thereby causing the conveyor belt to move the sterile items forward, so that the sterile items are transported to the depth of the collection box for storage.

[0026] The beneficial effects of this invention are as follows: This invention provides an electric push rod at the bottom of the tray and a pushing and conveying mechanism on the side wall of the tray. This allows the electric push rod to be adjusted under the control of the staff to adjust the tilt of the collection box according to the different weights of sterile items, so that the sterile items can fall safely into the collection box. Moreover, when the sterile items are heavy, the tilt can be reduced and the conveying mechanism can be used to transport the heavier sterile items to the depth of the collection box, thus facilitating storage. This invention provides a connecting rod on the sidewalls of the front and rear gears. Since the connecting rod is eccentrically positioned on the sidewalls of the front and rear gears, the push plate at the other end of the connecting rod will reciprocate during the rotation of the front and rear gears. This reciprocating motion occurs not only in the horizontal direction but also in the vertical direction. Therefore, sterile items on the push plate can be cyclically transported to the conveyor belt, and then the conveyor belt will take over the task of transporting sterile items. This invention features a reciprocating pusher plate and a driven conveyor belt. Since the distance between the conveyor belt and the pusher plate is much smaller than the size of the sterile items to be transported, the conveyor belt can seamlessly take over the task of transporting sterile items after the pusher plate pushes the sterile items forward. The fact that the conveyor belt is flush with the pusher plate when it is at its lowest position is also to better receive the sterile items. The sterile items are then sent to the rear of the collection box, where they are stacked and stored. This invention provides a spindle plate, a long lever, and a short lever on the side wall of the swing rod. As the short lever moves forward with the translation rod, it drives the arc plate and the swing rod to swing. When the short lever moves backward with the translation rod, the spindle plate, which is fixedly connected to the swing rod, is inclined, and the long lever is located at a high position. Therefore, after losing the thrust of the short lever, the swing rod will return to its initial position under the action of the counterweight, which facilitates the short lever to push the arc plate and the swing rod to swing again.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] like Figure 1 - Figure 3As shown, this embodiment provides a device for non-destructive sorting of sterile items, including a sorting machine 1 and several collection boxes 2. Several sorting platforms 3 are respectively arranged on both sides of the sorting machine 1. The collection box 2 is a box with one end open. Several collection boxes 2 are respectively installed on several sorting platforms 3. The opening of the collection box 2 faces the sorting machine 1. The height of the sorting machine 1 is greater than the height of the sorting platform 3. Therefore, the sterile items after sorting will fall into the collection box 2 under the action of gravity.

[0031] from Figure 3 - Figure 4 As can be seen from the content, the top of the sorting table 3 is inclined, and there are two electric push rods 4 on the top of the sorting table 3. The output ends of the two electric push rods 4 are rotatably connected to the tray 5. The collection box 2 is located inside the tray 5. The collection box 2 is divided into a front section and a rear section. The front section has a groove 6, and a push plate 7 is movably installed in the groove 6. Baffles 8 are fixed on both sides of the sorting table 3. The end of the push plate 7 facing the rear section of the collection box 2 has an arc design, so it will not collide with the side wall of the groove 6 when the push plate 7 is driven to reciprocate.

[0032] Reference Figure 4 and Figure 5 As can be seen from the content, both baffles 8 have push mechanisms on their side walls for driving the push plate 7. The push mechanisms include a dual-axis motor 15, a drive gear 16, a front gear 17, a connecting gear 18, a rear gear 19, two extension rods 20, and two transmission gears 21. The dual-axis motor 15 is fixedly mounted at the bottom of the tray 5. The two extension rods 20 are respectively fixedly mounted at the two output ends of the dual-axis motor 15. The drive gear 16 is fixedly mounted at the other end of the extension rod 20. The front gear 17, the connecting gear 18, and the two transmission gears 21 are all rotatably connected to the side walls of the baffles 8. The drive gear 16 meshes with one transmission gear 21, and the front gear 17 meshes with the same transmission gear 21. The connecting gear 18 is located between the two transmission gears. Between gears 21, connecting gear 18 meshes with two transmission gears 21 respectively, and rear gear 19 meshes with another transmission gear 21. Connecting rods 22 are eccentrically provided on the side walls of front gear 17 and rear gear 19 respectively. The two connecting rods 22 are rotatably connected to the side wall of push plate 7. The start of dual-shaft motor 15 will cause extension rod 20 to drive drive gear 16 to rotate. The transmission gear 21, connecting gear 18, front gear 17 and rear gear 19 that are meshed with it will rotate in succession. Since connecting rods 22 are eccentrically installed on the side walls of front gear 17 and rear gear 19, the rotation of front gear 17 and rear gear 19 will drive push plate 7 to reciprocate, thereby sending the sterile items on push plate 7 to conveyor belt 12.

[0033] The collection box 2 has movable holes 23 on both sides of its sidewalls. The connecting rod 22 passes through the movable holes 23. The end of the collection box 2 facing the connecting rod 22 is set with an oblique opening. Since the connecting rod 22 is fixedly set on the sidewall of the rear gear 19, the push plate 7 at the other end of the connecting rod 22 will reciprocate during the rotation of the front gear 17 and the rear gear 19, thereby repeatedly transporting the sterile items on the push plate 7 to the conveyor belt 12. The oblique opening is also designed to avoid the movement trajectory of the connecting rod 22, so as to facilitate the connecting rod 22 to drive the push plate 7 to reciprocate.

[0034] from Figure 4 and Figure 9 As can be seen, a through hole 9 is provided at the rear. A drive wheel 10 and a driven wheel 11 are rotatably connected in the through hole 9. A conveyor belt 12 is laid between the drive wheel 10 and the driven wheel 11. The conveyor belt 12 is flush with the side wall of the through hole 9. The distance between the conveyor belt 12 and the push plate 7 is less than 5cm. The height of the push plate 7 is flush with that of the conveyor belt 12. The distance between the conveyor belt 12 and the push plate 7 should be much smaller than the size of the sterile items to be conveyed. Therefore, after the push plate 7 pushes the sterile items forward, the conveyor belt 12 can seamlessly take over the task of conveying sterile items. The fact that the conveyor belt 12 is flush with the push plate 7 when it is at its lowest position is also for better handling of sterile items.

[0035] Reference Figure 6 and Figure 7 As can be seen from the content, a side turntable 24 is fixedly connected to the side wall of the rear gear 19. Two protruding rods 25 are eccentrically installed on the side wall of the side turntable 24 away from the rear gear 19. A translation rod 26 is slidably connected to the side wall of the tray 5. A sliding rod 31 is fixedly installed on the side wall of the translation rod 26. A sliding groove 32 is opened on the side wall of the tray 5. The sliding rod 31 is slidably connected to the inner wall of the sliding groove 32. The setting of the sliding rod 31 and the sliding groove 32 will make the translation of the translation rod 26 more stable. Moreover, the setting of the sliding rod 31 can also leave a distance between the translation rod 26 and the tray 5, so that the movement of the translation rod 26 will not affect the rotation of the rear gear 19, the connecting gear 18, etc.

[0036] A push rod 27 is fixedly installed on the side wall of the translation rod 26, and the side wall of the push rod 27 abuts against the side wall of the protruding rod 25. A protrusion 28 is fixedly installed on the side wall of the translation rod 26 away from the push rod 27. A curved rod 29 is rotatably connected to the side wall of the baffle 8. The curved rod 29 is L-shaped, with one end located on the movement trajectory of the protruding rod 25 and the other end of the curved rod 29 having a movable slot 30. The protrusion 28 is located inside the movable slot 30. The rotation of the rear gear 19 will drive the side turntable 24 to rotate. The protruding rod 25 on the side wall of the side turntable 24 will rotate accordingly, thereby causing the curved rod 29 and the push rod 27 that are opposed to it to be pushed by the protruding rod 25 in turn. When the push rod 27 is pushed, the push rod 27 will drive the translation rod 26 to move forward, and then the protruding rod 25 will leave the push rod 27. The protruding rod 25 on the other side will push the curved rod 29 to rotate, thereby causing the movable slot 30 to drive the protrusion 28 and the translation rod 26 to move backward. Therefore, the translation rod 26 will reciprocate in translational motion.

[0037] from Figure 8 - Figure 12 From the content, we can see that a rotating rod 13 is fixedly installed on the side wall of the drive wheel 10. The rotating rod 13 passes through the side wall of the collection box 2 and is fixedly installed on a rotating disk 14. The side wall of the tray 5 is provided with a conveying mechanism for driving the rotating disk 14. The conveying mechanism includes a swing rod 33, a spindle plate 34, a long lever 35, a short lever 36, a ratchet 37, a drive rod 38, and a drive disk 39. The swing rod 33 and the translation rod 26 are movably arranged together. The swing rod 33 is fixedly connected to the spindle plate 34. The middle position of the spindle plate 34 is rotatably connected to the side wall of the tray 5. The long lever 35 and the short lever 36 are rotatably connected to the side walls at both ends of the spindle plate 34, respectively. The side wall of the ratchet 37 is fixedly connected to the drive rod 38. The drive rod 38 passes through the side wall of the tray 5 and is fixedly installed on the side wall of the tray 5. The drive disc 39 is fixedly connected to the side wall. The side walls of the long lever 35 and the short lever 36 abut against the side wall of the ratchet 37. The drive disc 39 is movably connected to the rotating disc 14. The ratchet 37 is located between the side turntable 24 and the side wall of the tray 5. The long lever 35 and the short lever 36 are both L-shaped. The short side of the long lever 35 and the short side of the short lever 36 abut against the side wall of the ratchet 37. The swing of the swing rod 33 will cause the spindle plate 34 to rotate, which will cause the long lever 35 and the short lever 36 to lock the ratchet 37 in sequence. Therefore, the ratchet 37 will drive the drive wheel 10 to rotate in one direction. The conveyor belt 12 laid on the drive wheel 10 will push the sterile items on the conveyor belt 12 to the depth of the collection box 2, so that the collection box 2 can store the sterile items.

[0038] A short rod 40 is fixedly connected to the side wall of the translation rod 26, and an arc plate 41 is fixedly installed on the side wall of the swing rod 33. The short rod 40 abuts against the inner wall of the arc plate 41. When the short rod 40 moves forward with the translation rod 26, it will drive the arc plate 41 and the swing rod 33 to swing. When the short rod 40 moves backward with the translation rod 26, since the spindle plate 34 fixedly connected to the swing rod 33 is inclined and the long lever 35 is located at a high position, after losing the thrust of the short rod 40, the swing rod 33 will return to its initial position under the action of the counterweight, which makes it convenient for the short rod 40 to push the arc plate 41 and the swing rod 33 to swing again.

[0039] The bottom of the tray 5 has two rotating holes 42, in which the rotating disk 14 and the drive disk 39 are located. The side wall of the rotating disk 14 has a vertical groove 43, and the side wall of the drive disk 39 has a vertical rod 44 fixedly installed. The vertical rod 44 is inserted into the vertical groove 43. Since the rotating disk 14 protrudes more than the collection box 2, in order to meet the rotation requirements of the rotating disk 14, the bottom of the tray 5 needs to be provided with rotating holes 42 for rotation. The vertical rod 44 and the vertical groove 43 can also make the drive disk 39 drive the rotating disk 14 to rotate together, and also facilitate the separation of the drive disk 39 and the rotating disk 14.

[0040] The working principle of this embodiment is as follows: First, the staff needs to assess the weight of the sterile items to be sorted, and then adjust the tilt of the tray 5 and the collection box 2 by the electric push rod 4 as needed, so as to avoid the steep slope causing the heavier sterile items to fall too fast and damage the packaging. When sorting some heavier sterile items, the slope of the collection box 2 needs to be slowed down. At this time, the falling speed of the sterile items will also be slowed down. In order to help the sterile items smoothly enter the depth of the collection box 2, the dual-axis motor 15 needs to be started. The start of the dual-axis motor 15 will cause the extension rod 20 to drive the drive gear 16 to rotate. The transmission gear 21 meshing with it will drive the front gear 17 and the connecting gear 18 to rotate together. The transmission gear 21 meshing with the other side of the connecting gear 18 will also drive the rear gear 19 to rotate. Since the connecting rod 22 is eccentrically installed on the side wall of the front gear 17 and the side wall of the rear gear 19, the rotation of the front gear 17 and the rear gear 19 will drive the push plate 7 to reciprocate. It reciprocates not only in the horizontal direction but also in the vertical direction, thereby sending the sterile items on the push plate 7 to the conveyor belt 12. Since the side wall of the rear gear 19 is fixedly connected to the side turntable 24, the rotation of the rear gear 19 will drive the side gear to rotate together. Therefore, the two protrusions 25 on the side wall of the side turntable 24 will rotate accordingly, which will cause the curved rod 29 and the push rod 27 that are opposed to it to be pushed by the protrusions 25 in sequence. When the push rod 27 is pushed, the push rod 27 will drive the translation rod 26 to move forward, and the rear protrusion 25 will leave the push rod 27. The other protrusion 25 will push the curved rod 29 to rotate, which will cause the movable slot 30 to drive the protrusion 28 and the translation rod 26 to move backward. Therefore, the translation rod 26 will reciprocate and translate. Under the combined action of the short rod 40 on the side wall of the translation rod 26 and the arc plate 41 on the side wall of the swing rod 33, the reciprocating translation of the translation rod 26 will drive the swing rod 33 to swing back and forth. The swing of the swing rod 33 will cause the spindle plate 34 to rotate, which will cause the long lever 35 and the short lever 36 to lock the ratchet 37 in sequence. The design of the ratchet 37 makes it only able to rotate in one direction. Therefore, the ratchet 37 will drive the drive wheel 10 to rotate in one direction. The conveyor belt 12 laid on the drive wheel 10 will then transport the sterile items pushed onto the conveyor belt 12 to the depth of the collection box 2, so that the collection box 2 can store the sterile items.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
