Description

Technical Field

[0001] This application belongs to the field of industrialized automated production technology, specifically relating to a conveying device and an automatic tray assembly equipment. Background Technology

[0002] Large-scale air separation units typically consist of hundreds of neatly arranged packing discs, each composed of hundreds or thousands of heat exchange fins. Aluminum foil rolls are unwound, punched, formed, and cut into corrugated heat exchange fins of varying lengths using an automated packing production line. These fins are then coiled into a circular shape according to a prescribed sequence, forming a neat packing disc. Depending on the application requirements, large-scale air separation units can have a diameter of up to 6 meters, while small-scale units can have a diameter as small as 0.3 meters. This necessitates a variety of packing disc diameter specifications.

[0003] Current industry practice: All heat exchange fins of a packing disc are continuously produced by an automated packing production line, and then transferred to a material handling platform with a corresponding diameter, where manual arrangement and assembly of the packing discs of that diameter are completed. Manual transfer has disadvantages such as low production efficiency, high labor intensity, poor product consistency, multiple turnover links, discontinuous production processes, and unstable product quality.

The unloading gantry robot is used to grab and move the fins to the positioning roller conveyor line or the horizontal flipping mechanism. The horizontal flipping mechanism is used to flip the fins horizontally and transfer them to the positioning roller conveyor line, so that the fin roller conveyor line alternately horizontally conveys forward and reverse fins to the positioning roller conveyor line.

[0007] In some embodiments, a first clearance opening is provided on the positioning roller conveyor line, and the horizontal flipping mechanism includes: A tilting frame, one side of which is connected to the finned roller conveyor line along the width direction, and the other side of which can rotate relative to the positioning roller conveyor line; A rotary drive assembly is used to drive the tilting frame to tilt horizontally, so that the tilting frame passes through the first clearance opening and tilts onto the positioning roller conveyor line.

[0008] In some embodiments, the servo positioning mechanism includes: A first slide rail is provided on the first side of the positioning roller conveyor line, and the first slide rail extends along the length direction; The mounting bracket is slidably mounted on the first slide rail via a slider. The mounting bracket is located above the positioning roller conveyor line and extends toward the second side of the positioning roller conveyor line. A first linear drive unit is mounted on the mounting frame and disposed on the second side near the positioning roller conveyor line; A positioning baffle is installed at the driving end of the first linear drive member, which is used to drive the positioning baffle to move in the vertical direction.

[0009] In some embodiments, the positioning roller conveyor line includes a plurality of positioning conveyor rollers arranged in sequence, and the side-push positioning mechanism includes: The side push baffle has a clearance notch for the positioning conveying roller to move through, and a connecting block extends from the side push baffle; The second linear drive is used to drive the side push plate to move linearly along the width direction, so that the side push plate and the positioning square tube cooperate to limit the fin in the width direction; A guide rod is provided, on which a linear bearing is slidably mounted. The linear bearing is connected to the connecting block. The second linear drive and the guide rod are both located below the conveying roller.

[0010] In some embodiments, the positioning roller conveyor line has multiple second clearance openings, and the vertical flipping mechanism includes: Multiple positioning square tubes are provided, each corresponding to one of the second clearance openings. A flipping roller is disposed between two adjacent positioning conveying rollers and connected to the positioning square tube. When the flipping roller flips to a horizontal state, the top peripheral wall of the flipping roller and the top peripheral wall of the positioning conveying roller are on the same horizontal plane. A rotary drive assembly is used to drive the positioning square tube together with the flipping roller to flip relative to the positioning roller conveyor line; A pressing assembly is installed at the end of the positioning square tube and is capable of moving downward to press the fins against the flipping roller.

[0011] In some embodiments, the rotary drive includes: A rotating shaft is located on the second side of the positioning roller conveyor line at intervals.

A servo positioning mechanism is located near the discharge end of the positioning roller conveyor line. After the fins are conveyed to the positioning roller conveyor line, the servo positioning mechanism positions the fins on the positioning roller conveyor line in the length direction. A side-push positioning mechanism and a vertical flipping mechanism cooperate to limit the fins on the positioning roller conveyor line in the width direction. Then, the vertical flipping mechanism clamps the fins on the positioning roller conveyor line and flips them from a horizontal state to a vertical state. The fins flipped to the vertical state are ready to be transferred to the material handling worktable for stacking and traying into packing trays. This application achieves automatic conveying of forward and reverse fins through the seamless connection of fin roller conveyor lines and positioning roller conveyor lines. Furthermore, the servo positioning mechanism and side-push positioning mechanism on the positioning roller conveyor line are used to position the fins in the length and width directions before flipping, thereby ensuring that the symmetrical center lines of fins of different lengths are in the same position. Finally, the vertical flipping mechanism on the positioning roller conveyor line flips the horizontally arranged fins to a vertical state, achieving a seamless conversion of fin posture. This enables automated continuous operation of fins from incoming material to pre-arranged trays, improving operational efficiency.

[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] The conveying device and automatic tray-assembly equipment according to this application are described below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, this application provides a conveying device, including a fin roller conveyor line 1 and a positioning roller conveyor line 4. The fin roller conveyor line 1 is used to receive fins 11 to be assembled into trays and to alternately convey forward and reverse fins 11 horizontally to the positioning roller conveyor line 4, so that the forward and reverse fins 11 can be conveyed alternately to prepare for subsequent tray assembly. The positioning roller conveyor line 4 is equipped with a servo positioning mechanism 5, a vertical flipping mechanism 7, and a side-push positioning mechanism 6. The servo positioning mechanism 5 is located near the discharge end of the positioning roller conveyor line 4 and is used to position the fins 11 on the positioning roller conveyor line 4 in the length direction. The vertical flipping mechanism 7 is used to clamp the fins 11 on the positioning roller conveyor line 4 and flip the fins 11 from a horizontal state to a vertical state. The side-push positioning mechanism 6 and the vertical flipping mechanism 7 cooperate to limit the fins 11 on the positioning roller conveyor line 4 in the width direction.

[0022] In this application, by setting up a seamless connection between the fin roller conveyor line 1 and the positioning roller conveyor line 4, fins 11 in both forward and reverse directions can be automatically conveyed. Furthermore, the servo positioning mechanism 5 and the side-push positioning mechanism 6 on the positioning roller conveyor line 4 are used to position the fins 11 in the length and width directions before flipping, thereby ensuring that the symmetrical center lines of the fins 11 of different lengths are in the same position. Finally, the vertical flipping mechanism 7 on the positioning roller conveyor line 4 is used to flip the horizontally arranged fins 11 to a vertical state, achieving a seamless change in the posture of the fins 11. This ensures the automated continuous operation of the fins 11 from incoming material to the pre-arranged tray, reduces intermediate buffering and transfer, improves work efficiency, reduces labor intensity, and ensures product consistency and quality stability.

[0023] The structure of the fin 11 in this application is as follows: Figure 6 As shown, the fins 11 are provided with continuous “V”-shaped guide grooves 1101. The guide grooves 1101 are distributed at a certain angle on the heat exchange fins 11. Each “V”-shaped guide groove 1101 has rows of heat dissipation holes 1102 distributed on both sides to achieve the heat exchange effect.

[0024] In some embodiments, the fin roller conveyor line 1 and the positioning roller conveyor line 4 are arranged side by side, and the conveying device also includes a feeding gantry robot 2 and a horizontal flipping mechanism 3; the feeding gantry robot 2 is located above the fin roller conveyor line 1; the horizontal flipping mechanism 3 is located between the fin roller conveyor line 1 and the positioning roller conveyor line 4. The feeding gantry robot 2 is used to grab and translate the fins 11 onto the positioning roller conveyor line 4 or the horizontal flipping mechanism 3. The horizontal flipping mechanism 3 is used to horizontally flip the fins 11 and transfer them onto the positioning roller conveyor line 4, so that the fin roller conveyor line 1 alternately horizontally conveys the forward and reverse fins 11 to the positioning roller conveyor line 4.

[0025] In this embodiment, after the fins 11 are processed and cut on the automatic filling production line, they are conveyed by the fin roller conveyor line 1 to the area directly below the unloading gantry robot 2. Due to the air separation equipment heat exchanger flow guide design requirements, the fins 11 need to be stacked alternately in opposite directions. Therefore, after the gripper 201 on the unloading gantry robot 2 picks up the fins 11 from the fin roller conveyor line 1, it is transferred to the positioning roller conveyor line 4 through two methods. One method is that the gripper 201 of the unloading gantry robot 2 directly picks up the fins 11 and moves them horizontally to the positioning roller conveyor line 4. The other method is that the gripper 201 of the unloading gantry robot 2 picks up the fins 11 and moves them horizontally to the horizontal flipping mechanism 3. The horizontal flipping mechanism 3 then horizontally flips the fins 11 and transfers them to the positioning roller conveyor line 4. The above two methods are carried out continuously and alternately, thereby ensuring that the fins 11 conveyed backward by the positioning roller conveyor line 4 can be transported alternately in opposite directions.

[0026] In some embodiments, the positioning roller conveyor line 4 has a first clearance opening 401, and the horizontal flipping mechanism 3 includes a flipping frame 303 and a rotary drive assembly. One side of the flipping frame 303 along the width direction is connected to the finned roller conveyor line 1, and the other side can rotate relative to the positioning roller conveyor line 4. The rotary drive assembly is used to drive the flipping frame 303 to perform horizontal flipping, so that the flipping frame 303 passes through the first clearance opening 401 and flips onto the positioning roller conveyor line 4. The first clearance opening 401 is a "U"-shaped groove, and the rotary drive assembly can be a first servo motor 301. When the horizontal flipping mechanism 3 is working, the fins 11 of the finned roller conveyor line 1 can horizontally enter the flipping frame 303. The first servo motor 301 drives the flipping frame 303 through a coupling to horizontally flip the fins 11 onto the positioning roller conveyor line 4, and the multiple first clearance openings 401 on the positioning roller conveyor line 4 avoid the flipping frame 303.

[0027] like Figure 4 As shown, the servo positioning mechanism 5 includes a first slide rail 505, a mounting bracket 503, a first linear drive 504, and a positioning baffle 506. The first slide rail 505 is located on the first side of the positioning roller conveyor line 4 and extends along the length direction. The mounting bracket 503 is slidably mounted on the first slide rail 505 via a slider 502. The mounting bracket 503 is located above the positioning roller conveyor line 4 and extends toward the second side of the positioning roller conveyor line 4. The first linear drive 504 is mounted on the mounting bracket 503 and is located near the second side of the positioning roller conveyor line 4. The positioning baffle 506 is mounted on the drive end of the first linear drive 504, and the first linear drive 504 is used to drive the positioning baffle 506 to move in the vertical direction.

[0028] When the length of the fin 11 currently being conveyed by the positioning roller conveyor line 4 matches the theoretical length data, the servo positioning mechanism 5, based on the currently conveyed fin 11 length data, drives the mounting bracket 503 on the slider 502 via the second servo motor 501 to move the first linear drive 504 to the corresponding position on the first slide rail 505. The fin 11 length and the distance the drive end of the first linear drive 504 moves can be calculated in advance using a formula input from an external control unit. Since this is a common method in existing technology, it will not be elaborated upon here. Then, the first linear drive 504 drives the positioning baffle 506 to move vertically downwards to near the outer surface of the positioning conveyor roller 403, blocking and positioning the fin 11. This ensures that after each fin 11 of different lengths is positioned by the servo positioning mechanism 5, the symmetrical center lines along the length direction of all fins 11 of different lengths are at the same position. Then, the fins 11 are moved and gripped to the material handling table 10 by the material handling mechanism 8 (which can be a material handling robot), so that the outer contour of all the fins 11 in the length direction is wrapped into a circle, thereby forming a regular cylindrical packing disc 12.

[0029] In some embodiments, the positioning roller conveyor line 4 includes a plurality of positioning conveyor rollers 403 arranged in sequence, such as Figure 5 As shown, the side-push positioning mechanism 6 includes a side-push baffle 601, a second linear drive 602, and a guide rod 605. The side-push baffle 601 has a clearance notch for the positioning conveying roller 403 to pass through, and a connecting block 603 extends from the side-push baffle 601. The second linear drive 602 is used to drive the side-push baffle 601 to move linearly in the width direction so that the side-push baffle 601 and the positioning square tube 701 cooperate to limit the width direction of the fin 11. A linear bearing 604 is slidably provided on the guide rod 605, and the linear bearing 604 is connected to the connecting block 603. The second linear drive 602 and the guide rod 605 are both located below the conveying roller.

[0030] In this embodiment, multiple sets of side-push positioning mechanisms 6 are embedded at intervals along the length direction on the positioning roller conveyor line 4. After the fin 11 is positioned in the length direction, the side-push positioning mechanism 6 pushes the fin 11 to fit against the positioning square tube 701 of the vertical flipping mechanism 7, thereby positioning the fin 11 in the width direction. Since the side-push baffle 601 is provided with two clearance notches to avoid the positioning conveyor roller 403, when limiting the width direction, the second linear drive 602 pushes the connecting block 603 to drive the side-push baffle 601 to move along the guide rod 605 through the linear bearing 604, pushing the fin 11 to fit against the positioning square tube 701, thereby achieving the positioning of the fin 11 in the width direction.

[0031] like Figure 3 As shown, the positioning roller conveyor line 4 has multiple second clearance openings 404. The vertical flipping mechanism 7 includes a positioning square tube 701, a flipping roller 702, a rotary drive assembly, and a pressing assembly. The number of positioning square tubes 701 is multiple and they are arranged one-to-one with the second clearance openings 404. The flipping roller 702 is located between two adjacent positioning conveyor rollers 403 and connected to the positioning square tube 701. When the flipping roller 702 flips to a horizontal state, the top peripheral wall of the flipping roller 702 and the top peripheral wall of the positioning conveyor roller 403 are on the same horizontal plane. The rotary drive assembly is used to drive the positioning square tube 701 and the flipping roller 702 to flip relative to the positioning roller conveyor line 4. The pressing assembly is installed at the end of the positioning square tube 701 and can move downward to press the fins 11 onto the flipping roller 702.

[0032] The second clearance opening 404 is also a U-shaped groove structure. In this embodiment, the vertical flipping mechanism 7 is equipped with a row of flipping rollers 702, which are positioned in the middle of the two positioning conveying rollers 403 to prevent interference between the flipping rollers 702 and the positioning conveying rollers 403 during the flipping process. A corresponding second clearance opening 404 is provided at the intersection of the positioning roller conveyor line 4 and the flipping rollers 702 to avoid interference. When the vertical flipping mechanism 7 flips to a horizontal state, the flipping rollers 702 are inserted in the middle of the two positioning conveying rollers 403, and the outer surface of the flipping rollers 702 is on the same horizontal plane as the outer surface of the positioning conveying rollers 403.

[0033] In some embodiments, the rotary drive 705 includes a rotary shaft 706 and a rotary drive 705. The rotary shaft 706 is spaced apart on the second side of the positioning roller conveyor line 4. Each positioning square tube 701 is connected to the rotary shaft 706 via a first connecting rod. The first connecting rod extends from the rotary shaft 706 toward the positioning roller conveyor line 4 and overlaps at the second clearance opening 404. The rotary drive 705 is drivenly connected to the rotary shaft 706 and is used to drive the rotary shaft 706 to rotate. The rotary drive 705 is a rotary motor. During the flipping process, the rotary motor drives the rotary shaft 706 to rotate via a coupling and a support bearing 707, thereby causing the positioning square tubes 701 and the flipping roller 702 to flip, thus flipping the fins 11 on the flipping roller 702 from a horizontal state to a vertical state.

[0034] In some embodiments, the top end of the positioning square tube 701 extends with a second connecting rod in the width direction, and the clamping assembly includes a third linear drive 703 and a clamping block 704; the third linear drive 703 is disposed at the end of the second connecting rod; the clamping block 704 is disposed at the driving end of the third linear drive 703, and the third linear drive 703 is used to drive the clamping block 704 to move toward or away from the fin 11 to clamp or release the fin 11.

[0035] In this embodiment, after the fins 11 are positioned on the positioning roller conveyor line 4 in both length and width directions, the third linear drive 703 drives the clamping block 704 to press and fix the fins 11 onto the flipping roller 702. Then, the positioning baffle 506 and the side push baffle 601 retract sequentially, and the fins 11 pressed onto the flipping roller 702 are flipped under the drive of the rotation drive assembly. After the flipping is completed, the third linear drive 703 drives the clamping block 704 away from the fins 11 to release the clamping force on the fins 11, so as to wait for the gripping action of the gripping mechanism. To ensure the stability of the vertical state of the fins 11, a flipping limit frame 708 is also provided on the outside of the second side of the positioning roller conveyor line 4. The top surface of the flipping limit frame 708 is higher than the surface of the positioning roller conveyor line 4, and the flipping angle can be positioned and limited by the contact between the top surface of the flipping limit frame 708 and the bottom surface of the positioning square tube 701.

[0036] In some embodiments, the positioning roller conveyor line 4 is also provided with a length detection mechanism 402. The length detection mechanism 402 is used to detect the length of the currently conveyed fin 11. When the detected length data is consistent with the theoretical length data of the corresponding fin 11, the positioning roller conveyor line 4 is controlled to continue conveying. Otherwise, the conveying is stopped.
