Description

Technical Field

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

[0002] Disposable infusion sets are common medical consumables. After sterilization, they are used to establish a pathway between the vein and the medication solution, enabling intravenous infusion. After the infusion set is assembled into a finished product, it needs to be wound and packaged in a packaging bag. To ensure sterility and packaging efficiency, dedicated infusion set packaging machines are currently used for packaging.

[0003] Regarding infusion set packaging machines, Chinese patent publication number CN214452497U discloses an automatic feeding mechanism for infusion sets, comprising a feeding clamping and conveying mechanism, a two-to-four gripping mechanism disposed at the front end of which is a gripping and rotating mechanism. A bending mechanism is disposed at the front end of the gripping and rotating mechanism, and linear modules extending outward on either side of the bending mechanism connect to an existing infusion tube winding device. During the infusion tube packaging process, the feeding clamping and conveying mechanism loads the material, which is then removed from the feeding clamping and conveying mechanism by the two-to-four gripping mechanism. The gripping and rotating mechanism then receives the material from the two-to-four gripping mechanism and transfers it to the bending mechanism. The bending mechanism then bends the exhaust pipe of the infusion tube into an arc shape for subsequent processing. The linear module then drives the bending mechanism to the next step, completing the entire 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 drawbacks: The loading mechanism is a front-loading mechanism on the infusion pump packaging machine. During the loading process, workers are required to straighten the infusion pumps one by one and align them with the feed guide. The infusion pumps are then hung into the feed guide in a naturally drooping position to feed the feed guide. Subsequent workstations or mechanisms then remove and package the infusion pumps. This inconvenient feeding method still requires manual loading, especially for large-scale packaging of infusion pumps. This method is labor-intensive and inefficient, and urgently needs improvement. Utility Model Content

[0005] The purpose of the present invention is to solve the above problems 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:

[0007] The feeding device of the infusion pump 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 with the support rod and drives the support rod to continuously reverse forward and backward, the support rod is provided with a loading area and a feeding area, the loading area is for hanging the infusion pump and the two ends of the infusion pump are drooped, the baffle 1 and the baffle 2 are respectively arranged on both sides of the frame and limit the two ends of the infusion pump; the synchronous belt is rotatably arranged on the frame, the synchronous belt is driven by the 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 with the synchronous belt, and the synchronous belt can drive the swing frame to move the infusion pump in the loading area to the feeding area.

[0008] Through the above technical solution, the feeding device is used in conjunction with the infusion packing machine, and the feeding area is close to the infusion packing machine; workers or manipulators only need to hang the bundled finished infusion packs in the loading area, and the two ends of the infusion packs 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 packs stacked on the support rod are flattened. At the same time, the two ends of the infusion packs are respectively limited by baffles 1 and 2 to prevent the infusion packs 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 packs in the loading area to the feeding area, and then the infusion packing machine takes the infusion packs on the support rod for the next step of packaging. In other words, the feeding device only needs to stack the infusion packs and hang them on the support rod, and the swing frame feeds the infusion packs. The feeding automation level is high, the labor intensity of the workers is low, and this feeding method is more convenient.

[0009] In the aforementioned infusion pump feeding device, the feeding device further includes a push rod slidably mounted on the frame, the push rod cooperating with the support rod to spread the infusion pump. A second driving member is provided on the frame to drive the push rod to slide, and the push rod is capable of flattening the infusion pump on the support rod. The infusion pump is placed simultaneously on the support rod and the push rod, effectively supporting the infusion pump with the support rod and the push rod simultaneously supporting the infusion pump. The push rod abuts the infusion pump, and the second driving member drives the push rod to move, thereby moving the infusion pump, thereby improving the efficiency of flattening the infusion pump.

[0010] In the aforementioned infusion pump feeding device, the support rod has a smooth outer surface, the push rod is parallel to the support rod, and both ends of the push rod are slidably connected to the frame via guide rods. The smooth support rod reduces the movement resistance of the infusion pump, preventing it from being scratched by the support rod. The push rod is parallel to the support rod, ensuring that the second driver does not interfere with the operation of the swing frame when driving the push rod.

[0011] In the above-mentioned infusion pump 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, and the push piece 1 and the push piece 2 are rotatably connected to the slider 1. The connecting rod connects the push piece 1 and 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 pump on the support rod is fed toward the feeding area, the infusion pump will press the push piece 1 and the push piece 2 as a whole toward the feeding area. After the infusion pump 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.

[0012] In the aforementioned infusion set feeding device, the first and second pusher pieces are located on either side of the support rod, with their upper ends protruding from the support rod. When erected, the upper ends of the first and second pusher pieces are higher than the support rod. When the swing frame moves toward the feeding area, the first and second pusher pieces can synchronously translate the infusion set from either side of the support rod, preventing the infusion set from tilting after movement.

[0013] In the aforementioned infusion set feeding device, the upper end of the first pusher piece is provided with an inclined or curved surface, and the second pusher piece has the same structure as the first pusher piece. The inclined or curved surface prevents the first and second pusher pieces from damaging the outer wall of the infusion set during swinging. The identical structure of the first and second pusher pieces facilitates processing and assembly.

[0014] In the aforementioned infusion pump feeding device, at least two swinging frames are provided, spaced apart and connected to the timing belt. The two swinging frames cooperate to move the infusion pumps on the support rods to prevent excessive stacking of infusion pumps. Furthermore, the swinging frames prevent infusion pumps in the feeding area from retreating toward the upper feeding area.

[0015] In the aforementioned infusion pump feeding device, the rear end of the slide rail is slidably connected to a second slider, which is positioned adjacent to the feeding area. A pusher is mounted on the second slider, and a pusher cylinder is mounted on the frame. The output end of the pusher cylinder is connected to the pusher, which is used to gather the infusion pumps in the feeding area. The pusher cylinder's output end pushes the pusher toward the upper feeding area, thereby maintaining the infusion pumps in the feeding area within a predetermined area, allowing the next station to retrieve the infusion pumps from the feeding area.

[0016] In the aforementioned infusion set feeding device, a push-out cylinder is positioned on the frame near the feeding area. A push rod is located at the output end of the push-out cylinder. The push rod is used to lift an infusion set from the support rod. The push rod has a recess for placing a single infusion set. The output end of the push-out cylinder drives the push rod upward, lifting a single infusion set from the feeding area for removal by the next station, thereby improving the success rate of feeding.

[0017] In the aforementioned infusion pump feeding device, a swing mechanism is provided on the frame, comprising a swing motor, an eccentric weight, and a rocker arm. The swing motor is mounted on the frame, the eccentric weight is rotatably connected to the frame, and the eccentric weight is connected to the output end of the swing motor. The rocker arm is mounted on the eccentric weight and eccentrically disposed relative to the output end of the swing motor. The rocker arm rotates about the output end of the swing motor to strike the infusion pump hose. During the flattening of the infusion pump, the swing motor drives the rocker arm to rotate, causing it to strike the lower end of the infusion pump, thereby preventing the lower end of the infusion pump from sticking.

[0018] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0019] This feeding device is used in conjunction with an infusion set packaging machine. Workers or a robot simply hang bundles of infusion sets in the loading area. A synchronous belt drives the swing rack to quickly move the sets from the loading area to the feeding area, quickly replenishing any missing sets and ensuring a high density of sets in the feeding area. Support rods and push rods work together to evenly spread the sets on the support rods, while the push rack concentrates the sets in the feeding area. Sets in the feeding area are successively ejected by the push rods and passed to the next workstation for removal. This feeding device offers a more convenient loading method, a higher degree of automation, and reduced labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] 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.

[0041] An infusion feeding device, such as Figures 1-11As shown, including rack 100, support rod 200, push rod 300, synchronous belt 400 and swing rack 500, the rack 100 is provided with driving part one 110, driving part two 120, baffle one 130, baffle two 140, slide rail 420, the support rod 200 is rotationally arranged on the rack 100, the output end of driving part one 110 is connected with support rod 200 and drives support rod 200 to continuously rotate forward and reverse, support rod 200 has loading area 210, feeding area 220, feeding area 220 is close to the next station, loading area 210 supplies infusion set 1 suspension, both ends of infusion set 1 respectively droop above baffle one 130, baffle two 140, baffle one 130, baffle two 140 are respectively arranged on both sides of rack 100 and limit both ends of infusion set 1;

[0042] Synchronous belt 400 is rotationally arranged on the rack 100, synchronous belt 400 is driven by feeding motor 410 arranged on the side of rack 100, specifically, the rack 100 is rotationally connected with synchronous wheel, the output end of feeding motor 410 is provided with driving wheel, synchronous belt 400 is tensioned through synchronous wheel and driving wheel;Slide rail 420 is parallel to support rod 200 and located below support rod 200, swing rack 500 is slidingly arranged on slide rail 420, and swing rack 500 is connected with synchronous belt 400, synchronous belt 400 can drive swing rack 500 to move infusion set 1 in loading area 210 to feeding area 220.

[0043] Further, push rod 300 is parallel to support rod 200, both ends of push rod 300 are slidingly connected with rack 100 through guide rod 310, driving part two 120 is used for driving push rod 300 to reciprocate, push rod 300 abuts against the hose of infusion set 1, push rod 300 can drive infusion set 1 to move a short distance.

[0044] As shown in Figure 2 The rotation of support rod 200 is along its own axis, the reverse rotation of support rod 200 is clockwise rotation towards push rod 300 (or baffle one 130), on the contrary, the forward rotation of support rod 200 is counterclockwise rotation, and the rotation stroke of forward rotation and reverse rotation of support rod 200 is same or close, so as to avoid infusion set 1 from falling off support rod 200;For example, support rod 200 rotates forward first, then support rod 200 rotates reverse, and the process is continuously repeated.

[0045] As shown in Figure 2-Figure 4As shown, the outer surface of the support rod 200 is smooth. The push rod 300 cooperates with the support rod 200 from below to expand the infusion set 1 into an N-shape, which is equivalent to the infusion set 1 being laid 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 movement of the push rod 300 can also drive the infusion set 1 to move, thereby accelerating the flattening of the infusion sets 1 stacked on the support rod 200.

[0046] In some embodiments, the push rod 300 is positioned lower than the support rod 200 or flush with the support rod 200 ; the first driving member 110 is a driving motor, and the second driving member 120 includes a driving cylinder 121 .

[0047] like Figure 3-Figure 7 As 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 piece 1 520 and the pushing piece 2 530 is offset, so that the lower ends of the pushing piece 1 520 and the pushing piece 2 530 droop under the action of their own weight, that is, the lower end of the swing frame 500 droops, 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 piece 1 520 and the pushing piece 2 530 maintain an upright state; the connecting rod 540 can rotate between the upper and lower layers of the synchronous belt 400.

[0048] 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 limits the rotational travel of the push piece 1 520 and the push piece 2 530 by abutting against the clips 511 .

[0049] When the swing frame 500 moves toward the upper feeding area 210, the upper ends of the pushing piece 1 520 and the pushing piece 2 530 are blocked by the infusion pump 1 on the support rod 200 and tilt toward the feeding area 220. When the pushing piece 1 520 and the pushing piece 2 530 tilt, the connecting rod 540 abuts against the upper layer of the synchronous belt 400, thereby preventing the pushing piece 1 520 and the pushing piece 2 530 from tilting excessively; when the swing frame 500 moves toward the feeding area 220, the upper ends of the pushing piece 1 520 and the pushing piece 2 530 stand up and are limited by the connecting rod 540 and the slider 1 510.

[0050] Pusher piece 2 530 has the same structure as pusher piece 1 520 . The upper ends of pusher piece 1 520 and pusher piece 2 530 are both provided with an inclined or curved surface to prevent the upper ends of pusher piece 1 520 and pusher piece 2 530 from hooking onto the infusion set 1 . The lower ends of pusher piece 1 520 and pusher piece 2 530 are heavier or longer, allowing the upper ends of pusher piece 1 520 and pusher piece 2 530 to naturally stand upright when not subject to external forces. As an alternative, pusher piece 1 520, pusher piece 2 530, and connecting rod 540 may be integrally formed.

[0051] There are at least two swing frames 500, which are spaced apart and connected to the synchronous belt 400. The two swing frames 500 have the same structure. In some embodiments, there are one or more swing frames 500.

[0052] 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 provided on the slider 2 600, and a pushing cylinder 620 is provided 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 concentrates the infusion pumps 1 in the feeding area 220, and does not cause all the infusion pumps 1 to be piled up at the end of the support rod 200.

[0053] like Figure 1 、 Figure 9 As shown, the frame 100 is provided with an ejection cylinder 700 near the feed area 220. A push rod 710 is provided at the output end of the ejection cylinder 700. The push rod 710 is offset from the support rod 200, and the upper end of the push rod 710 has a groove 711 for placing a single infusion set 1. The push rod 710 is used to lift the infusion set 1 on the support rod 200, thereby ejecting each stacked infusion set 1 individually. In this embodiment, multiple ejection cylinders 700 are provided at intervals, allowing multiple infusion sets 1 to be ejected simultaneously at a time.

[0054] like Figure 1 、 Figure 2 、 Figure 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.

[0055] Further, the eccentric block 820 is provided with a stop lever 840, the stop lever 840 is coaxially arranged with the output end of the swing motor 810, the stop lever 840 limits the lower end of the infusion set 1, and avoids large and disorderly swinging of the lower end of the infusion set 1.

[0056] The working principle of the utility model is as follows:

[0057] The feeding device is used in cooperation with the infusion set packaging machine, and the feeding area 220 is close to the material taking station of the infusion set packaging machine; workers or mechanical hands only need to hang the bundled infusion set 1 in the feeding area 210, the two ends of the infusion set 1 are n-shaped due to sagging, the driving part one 110 continuously drives the support rod 200 to forward rotate and reverse rotate along the axis of the support rod 200, so that the two ends of the infusion set 1 are repeatedly lifted and lowered, the infusion set 1 unevenly stacked on the whole support rod 200 is dispersed and flattened, the two sagging end portions of the infusion set 1 are respectively limited by the baffle one 130 and the baffle two 140, and the infusion set 1 is prevented from falling off the support rod 200; when the support rod 200 forward rotates and reversely rotates, the driving part two 120 drives the push rod 300 to slide, so that the flattening efficiency of the infusion set 1 is accelerated.

[0058] When the infusion set 1 in the feeding area 220 is short of material, the feeding motor 410 drives the synchronous belt 400 to rotate, the synchronous belt 400 drives the swing frame 500 to move to the feeding area 210, wherein the upper ends of the pushing piece one 520 and the pushing piece two 530 are blocked by the infusion set 1 on the support rod 200 and are tilted to the feeding area 220, after the swing frame 500 passes the infusion set 1, the upper end of the swing frame 500 is erected under the action of the weight, and the erected state of the swing frame 500 is maintained in cooperation with the connecting rod 540 and the sliding block one 510; after the feeding motor 410 drives the synchronous belt 400 to reversely rotate, the swing frame 500 slides along the slide rail 420 to the feeding area 220, the upper ends of the pushing piece one 520 and the pushing piece two 530 are still in the erected state, and the swing frame 500 can push the infusion set 1 in the feeding area 210 to the feeding area 220, so that rapid material supplementing of the feeding area 220 is realized.

[0059] The infusion set 1 is gathered at the end of the support rod 200, the push cylinder 620 first drives the push frame 610 to push once to the direction of the ejection cylinder 700, so that the infusion set 1 in the feeding area 220 is concentrated in the area between the push frame 610 and the swing frame 500, then the output end of the ejection cylinder 700 drives the ejecting rod 710 to eject, so that the infusion set 1 on the support rod 200 is ejected, and the material taking station of the infusion set packaging machine can take away the infusion set 1 ejected by the feeding area 220 to perform the next packaging operation.
