Description

Technical Field

[0001] The invention belongs to the technical field of medical device assembly equipment, and in particular relates to an infusion set feeding device. Background Art

[0002] Disposable infusion sets are a common medical consumable. After being sterilized, they are used to establish a channel between the vein and the drug solution to achieve intravenous infusion. After the infusion set is assembled into a finished product, it needs to be rolled up and put into a packaging bag. In order to ensure the aseptic packaging and packaging efficiency of the infusion set, it is currently often packaged by a dedicated infusion set packaging machine.

[0003] For the infusion set packaging machine, the Chinese patent with the publication number CN214452497U discloses an automatic feeding mechanism for infusion sets, including a feeding clamping and conveying mechanism, a two-to-four gripping mechanism is arranged at the front end of the feeding clamping and conveying mechanism, and a gripping and rotating mechanism is arranged at the front end of the two-to-four gripping mechanism; a bending mechanism is arranged at the front end of the gripping and rotating mechanism, and linear modules extending outward are arranged on both sides of the bending mechanism, and the linear modules are connected to the existing external equipment infusion tube winding device. In the process of infusion tube packaging and processing, the feeding clamping and conveying mechanism is used to load the material, the two-to-four gripping mechanism is used to pick up the material from the feeding clamping and conveying mechanism, the gripping and rotating mechanism receives the material from the two-to-four gripping mechanism and sends it to the bending mechanism, and then the exhaust pipe of the infusion tube is bent into an arc shape by the bending mechanism for subsequent processing, and then the bending mechanism is driven by the linear module to the next process step to complete the overall feeding process. Among them, the loading clamping and conveying mechanism includes two groups of parallel installed feeding belt groups; the feeding belt group includes a guide plate, which is composed of two parallel clamping plates, and a feeding guide groove connected to the feeding gap is formed between the two clamping plates, and the opening of the feeding guide groove is a trumpet-shaped opening.

[0004] The above technical solution has the following defects: the feeding mechanism belongs to the front feeding mechanism on the infusion set packaging machine. During the feeding process of the feeding mechanism, the staff needs to straighten the infusion sets one by one and align them with the feeding guide groove, and then hang the infusion sets into the feeding guide groove in a naturally drooping state to realize the feeding of the feeding guide groove, and then the subsequent stations or mechanisms will take the materials and package the infusion sets. In other words, this feeding method is not convenient and still requires manual feeding. Especially for large-scale infusion set packaging, this feeding method has high labor intensity and low feeding efficiency, which needs to be improved urgently. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose an infusion set feeding device. The technical problem to be solved by the present invention is: how to optimize the feeding method of the infusion set packaging machine.

[0006] The above technical objectives of the present invention can be achieved through the following technical solutions: A feeding device for an infusion set, the feeding device comprises a frame, a support rod, a synchronous belt and a swing frame, the frame is provided with a driving member 1, a baffle 1, a baffle 2 and a slide rail, the support rod is rotatably arranged on the frame, the output end of the driving member 1 is connected to the support rod and drives the support rod to continuously reverse in positive and negative directions, the support rod is provided with a loading area and a feeding area, the loading area is for hanging the infusion set and the two ends of the infusion set droop, the baffle 1 and the baffle 2 are respectively arranged on both sides of the frame and limit the two ends of the infusion set; the synchronous belt is rotatably arranged on the frame, the synchronous belt is driven by a feeding motor, the slide rail is parallel to the support rod, the swing frame is slidably arranged on the slide rail, and the swing frame is connected to the synchronous belt, and the synchronous belt can drive the swing frame to move the infusion set in the loading area to the feeding area.

[0007] Through the above technical scheme, the feeding device is used in conjunction with the infusion set packaging machine, and the feeding area is close to the infusion set packaging machine; workers or manipulators only need to hang the bundled finished infusion sets in the loading area, and the two ends of the infusion sets hang down in an n shape. The driving member 1 continuously drives the support rod to rotate forward and reverse along its own axis, so that the infusion sets stacked on the support rod are flattened, and at the same time, the two ends of the infusion sets are respectively limited by baffles 1 and 2 to prevent the infusion sets from falling from the support rod; then the feeding motor drives the synchronous belt to rotate, thereby driving the swing frame to move along the slide rail, and the swing frame can move the infusion sets in the loading area to the feeding area, and then the infusion set packaging machine takes away the infusion sets on the support rod for the next step of packaging. In other words, the feeding device only needs to stack the infusion sets and hang them on the support rod, and the swing frame feeds the infusion sets. The feeding automation is high, the labor intensity of workers is low, and this feeding method is more convenient.

[0008] In the above-mentioned infusion set feeding device, the feeding device further includes a push rod slidably arranged on the frame, the push rod cooperates with the support rod to open the infusion set, and a second driving member for driving the push rod to slide is arranged on the frame, and the push rod can flatten the infusion set on the support rod. The infusion set is laid on the support rod and the push rod at the same time, which is equivalent to the support rod and the push rod cooperating to support the infusion set at the same time, the push rod abuts against the infusion set, and the second driving member drives the push rod to move, which can drive the infusion set to move, thereby improving the flattening efficiency of the infusion set.

[0009] In the above-mentioned infusion feeding device, the outer surface of the support rod is smooth, the push rod is parallel to the support rod, and both ends of the push rod are slidably connected to the frame through guide rods. The smooth support rod can reduce the movement resistance of the infusion set and prevent the infusion set from being scratched by the support rod; the push rod is parallel to the support rod, ensuring that the second driving member will not interfere with the work of the swing frame when driving the push rod to move.

[0010] In the above-mentioned infusion feeding device, the swing frame includes a slider 1, a push piece 1, a push piece 2 and a connecting rod, the slider 1 is slidably connected to the slide rail, the push piece 1 and the push piece 2 are rotatably connected to the slider 1, the connecting rod connects the push piece 1 with the push piece 2, and the connecting rod is close to the direction of the loading area, the rotation center a of the push piece 1 and the push piece 2 is offset, so that the lower ends of the push piece 1 and the push piece 2 droop under the action of their own weight, and the connecting rod abuts against the slider 1 and is limited by the slider 1. When the infusion set on the support rod is fed toward the feeding area, the infusion set will press the push piece 1 and the push piece 2 as a whole toward the feeding area, and after the infusion set passes over the push piece 1 or the push piece 2, the upper ends of the push piece 1 and the push piece 2 stand up again under the action of their own weight until the connecting rod is limited by the slider 1.

[0011] In the above-mentioned infusion set feeding device, the push piece 1 and the push piece 2 are distributed on both sides of the support rod, and the upper ends of the push piece 1 and the push piece 2 protrude from the support rod. When the push piece 1 and the push piece 2 are erected, the upper ends are higher than the support rod. When the swing frame moves toward the feeding area, the push piece 1 and the push piece 2 can synchronously translate the infusion set from both sides of the support rod to prevent the infusion set from tilting after the movement.

[0012] In the above-mentioned infusion set feeding device, the upper end of the push piece 1 is provided with an inclined surface or an arc surface, and the push piece 2 has the same structure as the push piece 1. The inclined surface or the arc surface can prevent the push piece 1 and the push piece 2 from damaging the outer wall of the infusion set during the swinging process; the push piece 1 and the push piece 2 have the same structure, which can facilitate processing and assembly.

[0013] In the above-mentioned infusion device feeding device, at least two swing frames are provided, and the two swing frames are arranged at intervals and are both connected to the synchronous belt. The two swing frames cooperate with the infusion devices on the moving support rod to avoid excessive stacking of infusion devices. At the same time, the swing frames can also prevent the infusion devices in the feeding area from retreating to the upper feeding area.

[0014] In the above-mentioned infusion device feeding device, the rear end of the slide rail is slidably connected with a slider 2, the slider 2 is close to the feeding area, and a push rack is arranged on the slider 2, and a push cylinder is arranged on the frame, and the output end of the push cylinder is connected to the push rack, and the push rack is used to gather the infusion devices in the feeding area. The push rack at the output end of the push cylinder pushes the infusion devices in the feeding area toward the upper feeding area, thereby maintaining the infusion devices in the feeding area in a predetermined area, so that the next station can take the infusion devices in the feeding area.

[0015] In the above-mentioned infusion set feeding device, the frame is provided with an ejection cylinder near the feeding area, and the output end of the ejection cylinder is provided with an ejector rod, which is used to lift up the infusion set on the support rod, and the ejector rod has a groove for placing a single infusion set. The output end of the ejection cylinder drives the ejector rod to move upward, so that the ejector rod lifts up one infusion set in the feeding area, and then the ejector is taken away by the next station, thereby improving the success rate of feeding.

[0016] In the above-mentioned infusion feeding device, a swing mechanism is arranged on the frame, and the swing mechanism includes a swing motor, an eccentric block, and a swing rod. The swing motor is arranged on the frame, the eccentric block is rotatably connected to the frame, and the eccentric block is connected to the output end of the swing motor, and the swing rod is arranged on the eccentric block. The swing rod is eccentrically arranged with the output end of the swing motor, and the swing rod rotates around the output end of the swing motor to hit the hose of the infusion set. During the flattening process of the infusion set, the swing motor drives the swing rod to rotate, so that the swing rod hits the lower end of the infusion set, thereby preventing the lower end of the infusion set from sticking.

[0017] In summary, the beneficial effects of the present invention compared with the prior art are as follows: This feeding device is used in conjunction with the infusion set packaging machine. Workers or manipulators only need to hang bundles of infusion sets in the loading area, and the synchronous belt drives the swing frame to move, so that the infusion sets in the loading area can be quickly supplied to the feeding area, thereby quickly replenishing the missing infusion sets in the feeding area and ensuring the density of infusion sets in the feeding area. The support rod and the push rod cooperate to evenly spread the infusion sets on the support rod, and the push rack will concentrate the infusion sets in the feeding area; the infusion sets in the feeding area are successively pushed out by the push rod and handed over to the next station for removal. The feeding method of this feeding device is more convenient, with a higher degree of automation and low labor intensity for workers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] An infusion feeding device, such as Figure 1-Figure 11 As shown, it includes a frame 100, a support rod 200, a push rod 300, a synchronous belt 400 and a swing frame 500. The frame 100 is provided with a driving member 110, a driving member 120, a baffle 130, a baffle 140 and a slide rail 420. The support rod 200 is rotatably arranged on the frame 100. The output end of the driving member 110 is connected to the support rod 200 and drives the support rod 200 to continuously rotate forward and reverse. The support rod 200 has a loading area 210 and a feeding area 220. The feeding area 220 is close to the next station. The loading area 210 is used for hanging the infusion set 1. The two ends of the infusion set 1 are respectively suspended above the baffle 1 130 and the baffle 2 140. The baffle 1 130 and the baffle 2 140 are respectively arranged on both sides of the frame 100 and limit the two ends of the infusion set 1. The synchronous belt 400 is rotatably arranged on the frame 100, and the synchronous belt 400 is driven by a feeding motor 410 arranged on the side of the frame 100. Specifically, a synchronous wheel is rotatably connected to the frame 100, and a driving wheel is arranged at the output end of the feeding motor 410. The synchronous belt 400 is tensioned by the synchronous wheel and the driving wheel; the slide rail 420 is parallel to the support rod 200 and is located below the support rod 200, and the swing frame 500 is slidably arranged on the slide rail 420, and the swing frame 500 is connected to the synchronous belt 400, and the synchronous belt 400 can drive the swing frame 500 to move the infusion pump 1 in the loading area 210 to the feeding area 220.

[0022] Furthermore, the push rod 300 is parallel to the support rod 200, and both ends of the push rod 300 are slidably connected to the frame 100 through the guide rod 310. The driving member 120 is used to drive the push rod 300 to slide back and forth. The push rod 300 abuts against the hose of the infusion set 1, and the push rod 300 can drive the infusion set 1 to move a short distance.

[0023] like Figure 2 As shown, the rotation of the support rod 200 is along its own axis, and the reverse rotation of the support rod 200 is a clockwise rotation pointing to the direction of the push rod 300 (or the direction of the baffle 130). Conversely, the positive rotation of the support rod 200 is a counterclockwise rotation, and the positive and reverse rotation strokes of the support rod 200 are the same or close to each other, so as to prevent the infusion set 1 from slipping off the support rod 200; for example, the support rod 200 first rotates forward one circle, and then the support rod 200 rotates reversely one circle, and the process is repeated continuously.

[0024] like Figure 2-Figure 4 As shown, the outer surface of the support rod 200 is smooth, and the push rod 300 cooperates with the support rod 200 from below to open the infusion set 1 into an n-shape, which is equivalent to laying the infusion set 1 on the push rod 300 and the support rod 200, and the push rod 300 and the support rod 200 cooperate to support the infusion set 1. The second driving member 120 is used to drive the push rod 300 to slide back and forth. Since the infusion set 1 is in contact with the push rod 300, the push rod 300 can drive the infusion set 1 to move when it moves, thereby accelerating the flattening of the infusion sets 1 stacked on the support rod 200.

[0025] In some embodiments, the push rod 300 is located lower than the support rod 200 or flush with the support rod 200 ; the driving member 110 is a driving motor, and the driving member 2 120 includes a driving cylinder 121 .

[0026] like Figure 3-Figure 7As shown, the swing frame 500 includes a slider 1 510, a push piece 1 520, a push piece 2 530, and a connecting rod 540. The slider 1 510 is slidably connected to the slide rail 420, and the push piece 1 520 and the push piece 2 530 are rotatably connected to the slider 1 510. The push piece 1 520 and the push piece 2 530 are distributed on both sides of the support rod 200. The connecting rod 540 connects the push piece 1 520 and the push piece 2 530 into a whole, and the connecting rod 540 is close to the direction of the loading area 210. The push piece 1 520 and the push piece 2 The upper end of the second material piece 530 is higher than the support rod 200, and the common rotation center a of the pushing pieces 1 520 and the second material piece 530 is offset, so that the lower ends of the pushing pieces 1 520 and the second material piece 530 sag under the action of their own weight, that is, the lower end of the swing frame 500 sags, and the connecting rod 540 abuts against the slider 1 510 and is limited by the slider 1 510, so that the upper ends of the pushing pieces 1 520 and the second material piece 530 maintain an upright state; the connecting rod 540 can rotate between the upper and lower layers of the synchronous belt 400.

[0027] In some embodiments, two overlapping clips 511 are provided on the slider 1 510 , and the two clips 511 are clamped on the lower layer of the synchronous belt 400 , that is, the slider 1 510 is connected to the synchronous belt 400 through the two clips 511 , and the connecting rod 540 is abutted against the clips 511 , thereby limiting the rotational travel of the push piece 1 520 and the push piece 2 530 .

[0028] When the swing frame 500 moves toward the upper feeding area 210, the upper ends of the push pieces 1 520 and 530 are blocked by the infusion set 1 on the support rod 200 and fall toward the feeding area 220. When the push pieces 1 520 and 530 fall, the connecting rod 540 abuts against the upper layer of the synchronous belt 400, thereby preventing the push pieces 1 520 and 530 from falling excessively. When the swing frame 500 moves toward the feeding area 220, the upper ends of the push pieces 1 520 and 530 stand up and are limited by the connecting rod 540 and the slider 1 510.

[0029] The structure of the second push piece 530 is the same as that of the first push piece 520. The upper ends of the first push piece 520 and the second push piece 530 are both provided with an inclined surface or an arc surface to prevent the upper ends of the first push piece 520 and the second push piece 530 from hooking the infusion set 1. The lower ends of the first push piece 520 and the second push piece 530 are heavier or longer, so that the upper ends of the first push piece 520 and the second push piece 530 can stand up naturally when not interfered by external forces. As another solution, the first push piece 520, the second push piece 530 and the connecting rod 540 are integrally formed.

[0030] At least two swing frames 500 are provided, and the two swing frames 500 are arranged at intervals and are both connected to the synchronous belt 400. The two swing frames 500 have the same structure. In some embodiments, one or more swing frames 500 are provided.

[0031] like Figure 4 , Figure 8 As shown, the rear end of the slide rail 420 is slidably connected to a slider 2 600, the slider 2 600 is close to the feeding area 220, and a push rack 610 is arranged on the slider 2 600, and a pushing cylinder 620 is arranged on the frame 100, and the output end of the pushing cylinder 620 is connected to the pushing rack 610, and the output end of the pushing cylinder 620 drives the pushing rack 610 to move toward the upper feeding area 210, so that the pushing rack 610 can concentrate the infusion pumps 1 in the feeding area 220, and will not cause all the infusion pumps 1 to be piled up at the end of the support rod 200.

[0032] like Figure 1 , Fig. 9 As shown, the frame 100 is provided with an ejection cylinder 700 near the feeding area 220, and the output end of the ejection cylinder 700 is provided with an ejector rod 710, which is misaligned with the support rod 200, and the upper end of the ejector rod 710 has a groove 711 for placing a single infusion set 1, and the ejector rod 710 is used to lift the infusion set 1 on the support rod 200, so that the stacked infusion sets 1 on the support rod 200 are ejected one by one. In this embodiment, multiple ejection cylinders 700 are arranged at intervals, and multiple infusion sets 1 can be ejected at the same time each time.

[0033] like Figure 1 , Figure 2 , Fig.10 As shown, a swing mechanism 800 is provided on the frame 100, and the swing mechanism 800 includes a swing motor 810, an eccentric block 820, and a rocker arm 830. The swing motor 810 is provided on the frame 100, and the eccentric block 820 is rotatably connected to the frame 100, and the eccentric block 820 is connected to the output end of the swing motor 810. The rocker arm 830 is provided on the eccentric block 820, and the central axis of the rocker arm 830 is eccentrically arranged with respect to the output end of the swing motor 810. The rocker arm 830 rotates around the output end of the swing motor 810 and slaps the hose area at the lower end of the infusion set 1 to prevent the lower end of the infusion set 1 from sticking.

[0034] Furthermore, a shift lever 840 is provided on the eccentric block 820 , and the shift lever 840 is coaxially arranged with the output end of the swing motor 810 . The shift lever 840 limits the lower end of the infusion set 1 to avoid large and disordered swinging of the lower end of the infusion set 1 .

[0035] The working principle of the present invention is as follows: The feeding device is used in conjunction with an infusion set packaging machine, and the feeding area 220 is placed close to the material taking station of the infusion set packaging machine; workers or manipulators only need to hang the bundled infusion sets 1 in the loading area 210, and the two ends of the infusion sets 1 hang down in an N shape, and the driving member 110 continuously drives the support rod 200 to rotate forward and reverse along the axis of the support rod 200, thereby driving the two ends of the infusion set 1 to perform repeated lifting and lowering movements, so that the infusion sets 1 unevenly stacked on the entire support rod 200 are dispersed and flattened, and the two drooping ends of the infusion set 1 are respectively limited by the baffle 1 130 and the baffle 2 140 to prevent the infusion set 1 from falling off the support rod 200; when the support rod 200 rotates forward and reversely, the driving member 2 120 drives the push rod 300 to slide, thereby accelerating the flattening efficiency of the infusion set 1.

[0036] When the infusion set 1 in the feeding area 220 is out of material, the feeding motor 410 drives the synchronous belt 400 to rotate, and the synchronous belt 400 drives the swing frame 500 to move to the loading area 210, wherein the upper ends of the push pieces 1 520 and the push pieces 2 530 are blocked by the infusion set 1 on the support rod 200 and fall toward the feeding area 220. After the swing frame 500 passes over the infusion set 1, the upper end of the swing frame 500 will stand up under the action of its own weight, and the swing frame 500 will move to the feeding area 210. The upright state of the frame 500 is maintained by the connecting rod 540 and the slider 1 510; after the feeding motor 410 drives the synchronous belt 400 to rotate in the opposite direction, the swing frame 500 slides along the slide rail 420 to the feeding area 220, and the upper ends of the push pieces 1 520 and 530 are still in the upright state. The swing frame 500 can push the infusion pump 1 in the loading area 210 to the feeding area 220, thereby realizing rapid feeding of the feeding area 220.

[0037] The infusion sets 1 are gathered at the end of the support rod 200, and the pushing cylinder 620 first drives the pushing frame 610 to push toward the ejecting cylinder 700 once, so that the infusion sets 1 in the feeding area 220 are concentrated in the area between the pushing frame 610 and the swing frame 500, and then the ejecting cylinder 700 drives the ejecting rod 710 to eject, thereby lifting the infusion sets 1 on the support rod 200, and the material taking station of the infusion set packaging machine can take away the infusion sets 1 lifted up in the feeding area 220 to carry out the next packaging operation.

[0038] The specific embodiments described in this article are merely illustrative of the spirit of the present invention; technicians in the technical field to which the present invention belongs may make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the present invention or exceed the scope defined by the attached claims.
