Description

Technical Field

[0001] This invention relates to the field of material feeding and processing technology, and more specifically, to a rotary feeding device. Background Technology

[0002] A loading table is an auxiliary device in industrial automation used to automatically load workpieces. Its core function is to accurately transfer parts to be processed from the storage area to the working area of ​​the processing equipment. It is widely used in assembly, processing, and inspection processes in manufacturing to improve production efficiency and quality.

[0003] During the feeding process, the complex mechanical structure of the rotary feeding table leads to a lengthy feeding process and a significant increase in waiting time, which in turn drags down the overall feeding efficiency. At the same time, the equipment lacks a limit support structure, and the rotation must be interrupted during material handling. The frequent start-stop and alternating swinging affect the stability of the feeding process.

[0004] For example, the Chinese utility model patent (application number: 202021500950.8) discloses a "dual-station rotary feeding worktable," the description of which states: A dual-station rotary feeding worktable includes a worktable, a rotating component disposed in the middle of the worktable, a first positioning component disposed on the left side of the rotating component, a second positioning component disposed on the right side of the rotating component, and a buffer component disposed on the front side of the rotating component. The first positioning component, the buffer component, and the second positioning component are all disposed on the worktable. A support plate is disposed on the rotating component, and a first pressing component, a second pressing component, and a plurality of feeding holes are respectively disposed on the support plate. The first pressing component and the second pressing component are respectively disposed around the plurality of feeding holes. It has low cost, high working efficiency, small space occupation, and good market application value. The above patent can corroborate the defects of the prior art.

[0005] Therefore, we have made improvements to this by proposing a rotary feeding device. Summary of the Invention

A limiting auxiliary assembly is provided on one side of the arc plate.

[0011] As a preferred technical solution of this application, the two arc-shaped cylinders are fixedly installed in the arc-shaped groove, and the two arc-shaped cylinders are on the same side of the support plate.

[0012] As a preferred technical solution of this application, one of the arc-shaped cylinders is provided with a first conduit at the other end, and a diverter cylinder is fixedly installed at the other end of the first conduit. The other arc-shaped cylinder is provided with a second conduit at the other end, and the other end of the second conduit is installed on the other side of the diverter cylinder. A double arc partition is fixedly connected to the middle of the inner wall of the diverter cylinder. A sealing plate is movably installed above the double arc partition. A pressure relief valve is provided in the middle of both the first conduit and the second conduit.

[0013] As a preferred technical solution of this application, two support pipes are fixedly connected in a circumferentially evenly distributed manner above the sealing plate, and the other end of the support pipe is fixedly installed on one side of the feeding plate. A fixing frame is fixedly connected to one side of the outer wall of the diverter cylinder, and a support mesh plate is provided on the upper surface of both feeding plates.

[0014] As a preferred technical solution of this application, the limiting auxiliary component includes a sliding frame plate fixedly installed on the outer wall of the arc-shaped plate, and a semi-circular plate is provided below the sliding frame plate, and the semi-circular plate is fixedly installed on the surface of the support plate below the semi-circular plate.

[0015] As a preferred technical solution of this application, both ends of the semicircular plate are provided with limiting arc plates, and the limiting arc plates are movably connected to the sliding frame plate.

[0016] As a preferred technical solution of this application, an auxiliary gear is provided below the sliding frame plate, and an internal gear plate is provided below the inner wall of the semi-circular plate, wherein the auxiliary gear is meshed with the internal gear plate.

[0017] As a preferred technical solution of this application, a number of arc-shaped frame plates are fixedly installed on the lower surface of the support plate in a circumferentially evenly distributed manner, and are fixedly connected to two arc-shaped cylinders.

[0018] As a preferred technical solution of this application, the support plate has several ribs fixedly connected in a straight line at both ends, and an mounting plate is fixedly connected below several of the ribs on the same side.

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

[0020] In the scheme of this application:

[0021] 1. In order to solve the problem that the complex mechanical structure of the existing rotary feeding worktable leads to a long feeding process and significantly increased waiting time, which in turn drags down the overall feeding efficiency, this application uses a rotary cylinder to drive the auxiliary plate to rotate, which in turn drives the feeding plate located above the auxiliary plate to rotate. After hitting the limit contact rod, the plate stops moving and rotates in the opposite direction after feeding, hitting another limit contact rod. This alternating feeding is achieved by using a simple structure to perform alternating feeding, thereby reducing the feeding waiting time and improving the feeding efficiency.

[0022] 2. In order to solve the problem that the existing equipment lacks a limiting support structure, and the rotation must be interrupted during the material handling operation, and the frequent start-stop and alternating swing affect the stability of the feeding process, the following method is used: during the alternating feeding process, the push plate connected to the two arc frames is driven by the arc plate to slide synchronously and alternately in the corresponding arc cylinder. The sliding distance of the two arc frames in the arc cylinder is limited. This, together with the auxiliary plate, further limits the movement during the alternating rotation process, thereby improving the stability of the start-stop process.

[0023] 3. The auxiliary gear under the sliding frame plate meshes with the internal gear plate in the semi-circular plate, and the rolling meshing occurs during the rotation of the arc plate. This increases the rotational stability during alternating feeding, while also reducing friction and wear between the supporting structures, thus improving the motion and motion effect.

[0024] 4. During the alternating feeding process, the push plates connected to the two arc frames, driven by the arc plate, slide synchronously and alternately in the corresponding arc cylinders. The sliding distance of the two arc frames within the arc cylinders is limited. This, combined with the further limiting effect of the auxiliary plate during alternating rotation, allows the push plate connected to the second arc frame below the arc plate to enter the corresponding arc cylinder when one feeding plate is unloaded. The push plate then compresses the gas in the corresponding arc cylinder, causing the gas to flow through the conduit into the other unloaded feeding plate. The gas is then discharged through the support mesh plate, cleaning the dust from the feeding plate. During the loading process of the other feeding plate, the push plate connected to the first arc frame moves within the corresponding arc cylinder and moves outwards to draw air from the inner wall. This air then flows through the conduit... The material is drawn into the material by the suction force generated in the support mesh plate of the feeding plate. During a single material transport, the pusher plate is pushed into the corresponding arc-shaped cylinder, and the air inside is squeezed out through the connected conduit. Since the diameter of the auxiliary cylinder is larger than the diameter of the pipe, the air inside is difficult to be discharged. During the air exhaust process, the pressure relief valve is adjusted to a suitable release value to cooperate with the exhaust operation, so that the speed of the pusher plate entering the inner wall of the arc-shaped cylinder is reduced, thereby reducing the speed of the rotating cylinder and stabilizing the feeding process. This allows it to flexibly switch between the limit support structure, cleaning structure, adsorption structure and buffer structure, thereby improving the stability and efficiency of alternating material feeding.

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0039] As described in the background art, the complex mechanical structure of the rotary feeding table during the feeding process leads to a lengthy feeding process and a significant increase in waiting time, which in turn drags down the overall feeding efficiency. At the same time, the equipment lacks a limit support structure, and the rotation must be interrupted during the material handling operation. The frequent start-stop and alternating swing affect the stability of the feeding process, ultimately weakening the accuracy and stability of the feeding process.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 A rotary feeding device includes a support plate 1. A rotary cylinder 2 is provided in the middle of the upper surface of the support plate 1. An auxiliary plate 3 is provided at the output shaft end of the rotary cylinder 2. Two pneumatic telescopic rods 11 are symmetrically and evenly distributed on the upper surface of the auxiliary plate 3. A feeding plate 4 is provided at the upper end of the pneumatic telescopic rods 11. An alternating feeding assembly 5 is provided on one side of the auxiliary plate 3. A rotating assembly 6 is provided on the surface of the support plate. The alternating feeding assembly 5 includes a limiting block 503 fixedly installed on one side of the auxiliary plate 3. Two support frames 501 are symmetrically and evenly distributed and fixedly connected on the upper surface of the support plate 1. A limiting contact rod 502 is provided on the same side of the two support frames 501. When the rotary cylinder 2 rotates, it drives the two feeding plates 4 located above the auxiliary plate 3 to rotate around the center of the auxiliary plate 3. The limiting block 503 on one side of the auxiliary plate 3 hits the support frame 501 on the rotating side and rotates 180 degrees to contact the limiting contact rod 502 above the support frame 501, thereby limiting the position of the feeding plate 4.

[0044] The rotary cylinder 2 drives the auxiliary plate 3 to rotate, which in turn drives the feeding plate 4 located above the auxiliary plate 3 to rotate. After hitting the limit contact rod 502, the plate stops moving. After feeding is completed, the plate rotates in the opposite direction and hits another limit contact rod 502. This alternating feeding is achieved by using a simple structure to reduce feeding waiting time and improve feeding efficiency.

[0045] Example 2 further optimizes the rotary feeding device provided in Example 1, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the rotating assembly 6 includes an arc-shaped groove 601 on the surface of the support plate 1. Two side frames 605 are symmetrically and evenly distributed and fixedly connected on both sides of the lower surface of the auxiliary plate 3. An arc-shaped plate 606 is fixedly connected between the two side frames 605 on the same side. A first arc frame 607 is provided on one side below the arc plate 606, and a second arc frame 608 is provided on the other side below the arc plate 606. Both the first arc frame 607 and the second arc frame 608 are located in the arc-shaped groove 601. A push plate 609 is fixedly connected to the other end of both the first arc frame 607 and the second arc frame 608. An arc-shaped cylinder 602 is movably connected to the outer wall of the push plate 609. The push plate 609 and the arc-shaped cylinder 602 are connected to the arc-shaped groove 601. The cylindrical tube 602 is movably connected, and a limiting auxiliary component 7 is provided on one side of the arc plate 606. When the auxiliary plate 3 is rotated by the rotary cylinder 2, the arc plate 606 located below the two side frames 605 rotates accordingly, causing the first arc frame 607 and the second arc frame 608 located below the arc plate 606 to move accordingly. The push plate 609 connected to the second arc frame 608 is driven in the corresponding arc tube 602, and the push plate 609 connected to the second arc frame 608 is about to disengage from the corresponding arc tube 602. Then the push plate 609 connected to the first arc frame 607 enters its corresponding arc tube 602.

[0046] During the alternating feeding process, the push plate 609 connected to the two arc frames driven by the arc plate 606 slides synchronously and alternately in the corresponding arc cylinder 602. The sliding distance of the two arc frames in the arc cylinder 602 is limited. This, together with the auxiliary plate 3, further limits the movement during the alternating rotation process. It works in conjunction with the limit contact rod 502 to achieve double limiting, thereby improving the stability of the alternating process starting and stopping.

[0047] Furthermore, such as Figure 3 , Figure 5 and Figure 6 As shown, two arc-shaped cylinders 602 are fixedly installed in the arc-shaped groove 601, and the two arc-shaped cylinders 602 are located on the same side of the support plate 1. In order to achieve adsorption and cleaning simultaneously during the feeding process of a single stroke, the two arc-shaped cylinders 602 are located on the same side of the support plate 1.

[0048] Furthermore, such as Figure 2 , Figure 3 and Figure 7As shown, one of the arc-shaped cylinders 602 has a first conduit 603 at one end, and a diverter 612 is fixedly installed at the other end of the first conduit 603. The other arc-shaped cylinder 602 has a second conduit 604 at one end, and the other end of the second conduit 604 is installed on the other side of the diverter 612. A double arc baffle 615 is fixedly connected to the middle of the inner wall of the diverter 612. A sealing plate 614 is movably installed above the double arc baffle 615. Both the first conduit 603 and the second conduit 604 have pressure relief valves 611 in the middle. The gas is guided by the cooperation of the first conduit 603 and the second conduit 604. During the process of the two feeding plates 4 rotating alternately by 180 degrees, the sealing plate 614 rotates by 180 degrees, so that the two support pipes 613 connected to the sealing plate 614 are always on both sides of the double arc baffle 615, thereby cooperating with the adsorption and cleaning process of the feeding plate 4.

[0049] Furthermore, such as Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, two support pipes 613 are fixedly connected in a circumferentially even distribution above the sealing plate 614. The other end of the support pipe 613 is fixedly installed on one side of the feeding plate 4. A fixing frame 616 is fixedly connected to one side of the outer wall of the diverter 612. The upper surface of both feeding plates 4 is provided with a support mesh plate 610. The guide pipe is always connected to the feeding plate 4 through the support pipe 613. The two-section pipeline adapts to its alternating rotation process. The sealing plate 614 and the diverter 612 with double arc baffles 615 rotate together, which reduces the impact of the pipeline length on the pipeline during the alternating rotation process and increases the flexibility of the pipeline during use.

[0050] Example 3 further optimizes the rotary feeding device provided in Example 1 or 2, specifically, as follows: Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the limiting auxiliary component 7 includes a sliding frame plate 704 fixedly installed on the outer wall of the arc plate 606. A semi-circular plate 701 is provided below the sliding frame plate 704. The semi-circular plate 701 is fixedly installed on the surface of the support plate 1. When the arc plate 606 rotates, it drives the sliding frame plate 704 to move accordingly. The auxiliary gear 705 located below the sliding frame plate 704 meshes with the internal gear plate 702. As the arc plate 606 moves, the auxiliary gear 705 rolls and meshes on the outer wall of the internal gear plate 702.

[0051] The auxiliary gear 705 below the sliding frame plate 704 meshes with the internal gear plate 702 in the semi-circular plate 701, and rolls and meshes during the rotation of the arc plate 606. This increases the rotational stability during alternating feeding, while also reducing friction and wear between the supporting structures, thus improving the motion and motion effect.

[0052] Furthermore, such as Figure 3 As shown, both ends of the semicircular plate 701 are provided with limiting arc plates 703. The limiting arc plates 703 are movably connected to the sliding frame plate 704. The limiting arc plates 703 block the sliding frame plate 704 moving on the semicircular plate 701 and limit its range of motion.

[0053] Furthermore, such as Figure 3 and Figure 6 As shown, an auxiliary gear 705 is provided below the sliding frame plate 704, and an internal gear plate 702 is provided below the inner wall of the semi-circular plate 701. The auxiliary gear 705 is meshed with the internal gear plate 702. Through the meshing connection between the auxiliary gear 705 and the internal gear plate 702, sliding is converted into rolling meshing, thereby reducing friction and wear.

[0054] Furthermore, such as Figure 1 and Figure 2 As shown, several arc-shaped support plates 10 are evenly distributed and fixedly installed on the lower surface of the support plate 1, and are fixedly connected to two arc-shaped cylinders 602. The arc-shaped support plates 10 support the arc-shaped cylinders 602 in the arc-shaped grooves 601, thereby increasing the stability of the structure.

[0055] Furthermore, such as Figure 1 and Figure 2 As shown, the support plate 1 has several ribs 8 that are evenly distributed and fixedly connected at both ends in a straight line. On the same side, several mounting plates 9 are fixedly connected below the ribs 8. The mounting plates 9 connected to the ribs 8 are installed near the material handling equipment by bolts to facilitate the feeding operation.

[0056] The rotary feeding device provided by this invention is used as follows:

[0057] Working principle: The operator assembles the bolts with the mounting plate 9 and installs it near the material handling equipment. After completion, the material is placed in one of the feeding plates 4.

[0058] Rotary adsorption: The rotary cylinder 2 operates, driving the auxiliary plate 3 to rotate, causing the two feeding plates 4 above the auxiliary plate 3 to move accordingly. The arc plate 606 also moves accordingly, driving the push plate 609 connected to the first arc frame 607 to move in the corresponding arc cylinder 602, and moving outward to draw air from the inner wall. The air is then drawn into the arc cylinder 602 along the first guide tube 603, and the air in the corresponding cavity of the diversion cylinder 612 is also drawn. During the extraction process, the sealing plate 614 rotates accordingly, but this does not obstruct the air above this cavity. The support tube 613 is connected to the feeding plate 4, so that the support mesh plate 610 in the feeding plate 4 generates suction to adsorb the material in the feeding plate 4 for adsorption and conveying. When the limiting block 503 on one side of the auxiliary plate 3 is about to hit the limiting contact rod 502, the push plate 609 connected to the first arc frame 607 is about to disengage from the corresponding arc cylinder 602. After the impact stops rotating, the push plate 609 disengages from the arc cylinder 602, and the suction in the feeding plate 4 is lost. At this time, the material is taken out from the feeding plate 4 by the material taking equipment.

[0059] Rotary cleaning: While the first arc frame 607 drives the connected push plate 609 to move, the push plate 609 connected to the second arc frame 608 below the arc plate 606 enters the corresponding arc cylinder 602. The push plate 609 squeezes the gas in the corresponding arc cylinder 602. The gas enters the diversion cylinder 612 through the second conduit 604. It is separated by the double arc partition 615 in the diversion cylinder 612. It enters another unloaded feeding plate 4 through the support pipe 613 above this cavity. It is then discharged by the support mesh plate 610 to clean the dust from the feeding plate 4.

[0060] Alternating feeding: Rotary cylinder 2 rotates, driving auxiliary plate 3 to rotate 180 degrees in the forward direction. The limit block 503 on one side of auxiliary plate 3 then hits the limit contact rod 502 above support frame 501 and stops rotating. At this time, the material is transported to the vicinity of the picking device, completing one feeding cycle. Rotary cylinder 2 rotates again, driving auxiliary plate 3 to rotate 180 degrees in the reverse direction. The limit block 503 on the same side of auxiliary plate 3 then hits the limit contact rod 502 above another support frame 501 and stops rotating. Another material is then transported to the vicinity of the picking device. Pneumatic telescopic rod 11 extends, lifting the material to a suitable height for picking operation. This process is repeated to achieve alternating feeding.

[0061] Limiting aid: The arc plate 606 drives the push plate 609 connected to the two arc frames to slide synchronously and alternately in the corresponding arc cylinder 602, and the sliding distance of the two arc frames in the arc cylinder 602 is limited, so as to cooperate with the auxiliary plate 3 to further limit the movement during the alternating rotation process.

[0062] Squeezing buffer: During the alternating feeding process, the push plate 609 is pushed into the corresponding arc-shaped cylinder 602, squeezing the air inside and discharging it through the connected conduit. Since the diameter of the auxiliary cylinder is larger than the diameter of the conduit, the air inside is difficult to be discharged. During the air exhaust process, the pressure relief valve 611 is adjusted to a suitable release value to cooperate with the exhaust operation, so that the speed of the push plate 609 entering the inner wall of the arc-shaped cylinder 602 is reduced, thereby reducing the speed of the rotating cylinder 2 and stabilizing the feeding process.

[0063] Swinging support: During the rotation of the arc plate 606, the connected sliding frame plate 704 moves on the upper surface of the semicircular plate 701, and the auxiliary gear 705 located below the sliding frame plate 704 meshes with the inner tooth plate 702 on the inner wall of the semicircular plate 701. As the sliding frame plate 704 moves, the auxiliary gear 705 rolls and meshes on the inner wall of the inner tooth plate 702, which not only ensures support but also reduces wear during the friction process.
