Description

Fin storage and retrieval machine Technical Field

[0001] The invention relates to a fin storage and retrieval machine. Background Art

[0002] When producing fins for air-conditioning heat exchangers, the fins are generally stacked and piled up using a fin stacker (also called a stacking rack) with stacking needles before proceeding to the next step of processing.

[0003] The fin collector generally includes a support plate, a collection needle mounting plate, a tray, a spacer, a guard plate, and a collection needle. Although it can complete the general collection function, it is not convenient to move and cannot rotate. Therefore, when it is combined with other mechanisms such as fin stamping processing equipment and fin subsequent processing equipment, it still has the problems of insufficient flexibility and limited functions.

[0004] Although the existing fin storage and retrieval machine can make the fin collector rotate simultaneously when it moves on the work station, its structure still needs to be improved. Summary of the Invention

Therefore, the installation positions of several of the multiple reinforcing ribs are consistent with the positions of inserting the positioning steel needles, and the upper part of these reinforcing ribs is provided with non-perforated grooves. In this way, the steel needles pass through the fin stack from the upper part and are located in the groove at the lower part, and are dragged by the bottom surface of the reinforcing ribs so as not to fall to the bottom plate.

[0022] The flip frame and the lifting plate are integrated into one through a positioning mechanism. The specific structure of the positioning mechanism is: positioning pins are respectively set on both sides of the lifting plate, and positioning pin holes are set on the corresponding positions of the flip frame.

[0042] The present invention is further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0043] As shown in Figures 1-7, a fin storage and retrieval machine includes a base 1, an inner turntable 2, a rotary drive mechanism, a sheet collector (collection rack) 4, a sheet collection lifting mechanism 5, a discharge mechanism 6 and a sheet collector moving mechanism.

[0044] The inner turntable 2 and the rotary drive mechanism are installed on the base 1. The inner turntable 2 is connected to the rotary drive mechanism, and the rotary drive mechanism drives the turntable 2 to rotate relative to the base 1 at a set angle.

[0045] The rotary drive mechanism is relatively commonly used, as also mentioned in the collection device of patent 202022884059.5, and will not be repeated here.

[0046] The base 1 is provided with a material collection station and a material discharge station. The fin collection lifting mechanism 5 is provided at the material collection station, and the material discharge mechanism 6 is provided at the material discharge station. The fin collector moving mechanism moves the fin collector 4 filled with fins from the material collection station to the inner turntable 2. After the inner turntable 2 is rotated 180 degrees by the rotary drive mechanism, the fin collector moving mechanism moves the fin collector 4 to the material discharge station. The fin stack on the fin collector 4 is then discharged by the unloading mechanism 6.

[0047] The sheet collector (collection rack) 4 includes a bottom plate 401 , a collection needle mounting plate 402 , a lifting plate (lower support plate) 403 , a flip frame (upper support plate) 404 , guide rods 405 and 405 ′, a straightening plate 406 , a guide sleeve 407 , and a collection needle 30 .

[0048] The plurality of collecting needles 30 are vertically and spaced apart from each other on the collecting needle mounting plate 402. This structure is common in existing collecting racks and will not be described in detail.

[0049] The bottom plate 401 is provided with a plurality of equal-height limit blocks 4011 to limit the lowest position of the lifting plate 403 when it descends. A hole 4012 is also provided to limit the sheet collector 4. The position of the hole 4012 should be consistent with the rotating shaft 705 described below.

[0050] There are at least two or more collecting needle mounting plates 402, which are selected according to the length of the fins. In this embodiment, there are three collecting needle mounting plates, which are respectively installed in parallel on the base plate 401 through their own adjustment plates 4021. A plurality of positioning holes 4022 are provided on the adjustment plates 4021. The two ends of the collecting needle mounting plates 402 can be fixed on the positioning holes 4022 by screws 4023. In this way, the relative position between the two collecting needle mounting plates 402 can be changed by installing the collecting needle mounting plates 402 at different positioning holes 4022, so that the distance between the collecting needles 30 correspondingly installed on the collecting needle mounting plates 402 can be changed to adapt to fins of different lengths.

[0051] In order to facilitate the adjustment of the position of the collecting needle mounting plate 402, a slider and rail guide mechanism is also installed between the collecting needle mounting plate 402 and the adjustment plate 4021. The slider 4024 is installed on the collecting needle mounting plate 402, and the guide rail 4025 is installed on the adjustment plate 4021.

[0052] The lifting plate 403 is movably placed above the bottom plate 401 .

[0053] Both ends of the straightening plate 406 are placed on the lifting plate 403 . The straightening plate 406 is provided with a through hole 4061 for the collecting needle 30 to pass through. The diameter of the through hole 4061 is slightly larger than the diameter of the collecting needle 30 .

[0054] In order to better straighten the collecting needle 30, especially when the collecting needle is relatively long, an upper straightening plate 4062 is also provided. The upper straightening plate 4062 is arranged parallel to the top of the straightening plate 406, and a through hole 4061 is also provided thereon for the collecting needle 30 to pass through. The upper straightening plate 4062 and the straightening plate 406 are kept at a certain distance by a plurality of equal-height columns 4063. The equal-height columns 4063 are arranged between the upper straightening plate 4062 and the straightening plate 406, and the upper end thereof is connected to the upper straightening plate 4062, and the lower end is connected to the straightening plate 406.

[0055] The lower end of the collecting needle 30 is mounted on the collecting needle mounting plate 402 , and passes upward through the through hole 4061 of the straightening plate 406 , the through hole 4061 of the upper straightening plate 4062 , and the flip frame 404 in sequence.

[0056] In order to ensure the smooth movement of the lifting plate 403, a guiding mechanism is also provided, which includes a guide rod 405. The lower end of the guide rod 405 is installed on the collecting needle mounting plate 402, and the upper end passes through the lifting plate 403, the straightening plate 406 and the flip frame 404 in sequence. In this way, the lifting plate 403 can be guided by the guide rod 405 when it moves up and down.

[0057] Another guide mechanism is further provided on the outer side of the flip frame 404 , which includes another guide rod 405 ′ and a guide sleeve 407 . The lower end of the guide rod 405 ′ is mounted on the bottom plate 401 , and a guide sleeve 407 is sleeved thereon. The guide sleeve 407 is mounted on the lifting plate 403 .

[0058] In this way, the lifting plate 403 can be guided by the guide rod 405 and the other guide rod 405 ′ and move up and down smoothly.

[0059] In this embodiment, there are two other guide rods 405 ′ spaced apart from each other. The two guide rods 405 ′ are connected by a connecting plate 408 , which improves the guiding accuracy.

[0060] The flip frame 404 is placed on the lifting plate 403, and has plug holes 4041 on both sides. The plug holes 4041 can be movably connected by inserting the flip plug rod 610 of the flip mechanism 6 described below. A plurality of reinforcing ribs 4042 are also provided on the flip frame 404. The installation position of the plurality of reinforcing ribs 4042 is based on the principle of non-interference with the collecting needle 30 and the guide rod 405, thereby increasing the strength of 404 and ensuring the smooth lifting and flipping of the fin material stack.

[0061] In order to facilitate the unloading of the fin stack, after the collection is completed, several positioning steel needles (not shown in the figure) generally need to be inserted into each row of fins. Therefore, the installation positions of several of the above-mentioned multiple reinforcing ribs 4042 are consistent with the positions for inserting the positioning steel needles, and the upper parts of these reinforcing ribs 4042 are provided with non-perforated grooves 40421. In this way, the steel needles pass through the fin stack from the upper part and are located in the grooves 40421 at the lower part, and are dragged by the bottom surface of the reinforcing ribs 4042 so as not to fall onto the bottom plate 401.

[0062] The flip frame 404 and the lifting plate 403 are integrated into one through a positioning mechanism. The specific structure of the positioning mechanism in this embodiment is: positioning pins 409 are respectively provided on both sides of the lifting plate 403, and positioning pin holes (not shown in the figure) are provided at corresponding positions of the flip frame 404. When the flip frame 404 falls on the lifting plate 403, the positioning pins 409 on the lifting plate 403 are inserted into the positioning pin holes of the flip frame 404, thereby ensuring the combination accuracy of the two.

[0063] In order to prevent the upper part of the higher fin stack from tilting, a baffle 410 is also provided. The baffle 410 is installed on the adjustment plate 4021 through the support guide rod 4101 and the support plate 4102. The two ends of the support plate 4102 are also installed on the adjustment plate 4021, which makes it convenient to adjust the horizontal position of the baffle 410. The lower end of the support guide rod 4101 is installed on the support plate 4102, and passes through the lifting plate 403 and the flip frame 404 upward in turn. The two ends of the baffle 410 are supported by the support guide rod 4101 and are movably connected to the support guide rod 4101, which makes it convenient to adjust the height of the baffle 410.

[0064] The base 1 is provided with a slide groove 101 , and the inner turntable 2 is provided with a turntable slide groove 201 communicating with the slide groove 101 .

[0065] The sheet collector moving mechanism includes a motor 701, a gear 702, a rack 703, a sliding plate 704 and a rotating shaft 705. The motor 701 is installed on the inner turntable 2 and is connected to the gear 702. The gear 702 is engaged with the rack 703. The sliding plate 704 is installed on the rack 703 and is located in the slide groove 101 and the turntable slide groove 201. Its two sides are supported and guided by the slide groove 101 and the turntable slide groove 201. The rotating shaft 705 is installed on the sliding plate 704, which is always located in the hole 4012 of the bottom plate 401 of the sheet collector 4 described below. In this way, when the motor 701 drives the gear 702 to rotate, the rack 703 drives the sliding plate 704 to move along the slide groove 101 and the turntable slide groove 201, so that the rotating shaft 705 pulls the sheet collector 4 to move to the base 1 or to the inner turntable 2.

[0066] In order to ensure that the chip collector 4 moves smoothly when changing positions between the inner turntable 2 and the base 1, and to enable the chip collector 4 to rotate 90 degrees during the position change process to facilitate unloading or meet other design requirements, a turning groove 102 and a guide groove 103 are also provided on the base 1. The curve of the turning groove 102 is designed to ensure that the chip collector 4 rotates around the rotating shaft 705 to the required angle, and a turntable guide groove 202 is provided on the inner turntable 2, which is respectively connected to the turning groove 102 and the guide groove 103.

[0067] A guide shaft 4014 is installed on the bottom surface of the base plate 401 of the sheet collector 4, which cooperates with the steering groove 102 on the base and the turntable guide groove 202 on the turntable, and is always located in the groove where the steering groove 102 and the turntable guide groove 202 are connected, as well as the groove where the guide groove 103 and the turntable guide groove 202 are connected. In this embodiment, the turning groove 102 is set at the material collection station and the guide groove 103 is set at the unloading station. In the process of the chip collector moving mechanism of the material collection station moving the chip collector 4 from the base 1 to the inner turntable 2, the chip collector 4 rotates around the rotating shaft 705, and the guide shaft 4014 moves along the turning groove 102 toward the turntable guide groove 202. When the chip collector moving mechanism stops moving the chip collector 4, the chip collector 4 is moved from the base to the inner disk, and at the same time rotates 90 degrees clockwise around the rotating shaft 705. The guide groove 103 of the unloading station only serves to smoothly move the chip collector 4 from the inner turntable 2 to the base 1.

[0068] If the chip collector at the material collection station does not need to rotate 90 degrees, the specially designed turning groove 102 can be replaced with the guide groove 103; similarly, if the chip collector does not need to rotate 90 degrees at the material collection station, but needs to rotate 90 degrees at the unloading station, the position of the turning groove 102 and the guide groove 103 can be exchanged.

[0069] In order to ensure that the sheet collector 4 can collect materials smoothly at the collection station, two positioning holes 4013 are provided on the base plate 401, and positioning is achieved by a positioning mechanism. The positioning mechanism includes a cylinder 801 and a positioning column 802. The cylinder 801 is installed on the base 1 and is connected to the positioning column 802. Each positioning hole 4013 corresponds to a positioning mechanism. The positioning column 802 can be inserted into or withdrawn from the positioning hole 4013 by extending and retracting the piston rod of the cylinder 801. When collecting materials, the positioning column 802 is inserted into the positioning hole 4013. After the materials are collected, the positioning column 802 withdraws from the positioning hole 4013.

[0070] The sheet collecting and lifting mechanism 5 is composed of two groups arranged opposite to each other, each group including a support 501 , a movable column 502 , a horizontal driving mechanism, an up and down driving mechanism and a lifting seat 510 .

[0071] The support 501 is installed on the side of the base 1 and can also be made into an integral part with the base 1. The horizontal driving mechanism is a cylinder 503, which is installed on the support 501. Its piston rod is connected to the moving column 502. The up and down driving mechanism includes a motor 506, a screw rod 507 and a screw nut (not shown in the figure). The motor 506 is installed at the upper end of the moving column 502 and is connected to the screw rod 507. The upper and lower ends of the screw rod are respectively rotated by the moving column. The screw nut is sleeved on the outside of the screw rod 507 and is connected to the lifting seat 510. The moving column 502 and the lifting seat 510 can be driven to move back and forth in the horizontal direction by the extension and contraction of the piston rod of the cylinder 503. The screw rod 507 is driven to rotate by the motor 506, so that the screw nut drives the lifting seat 510 to move up and down.

[0072] In order to ensure smooth movement of the movable column 502 and the lifting seat 510, a slider and rail guide mechanism is set between the movable column 502 and the support 501, the slider 504 is installed on the movable column 502, and the slide rail 505 is installed on the support 501. A slider and rail guide mechanism is also installed between the movable column and the lifting seat 510, the slider 508 is installed on the lifting seat 510, and the slide rail 509 is installed on the movable column 502.

[0073] When preparing to gather materials, the piston rod of the cylinder 503 retracts, the lifting seat 510 is inserted into the bottom of the lifting plate 403, and the lifting plate 403 is dragged upward by the up and down driving mechanism, and rises to the position to start gathering materials. During the gathering process, the up and down driving mechanism drives the lifting seat 510 to descend intermittently. After the gathering is completed, the lifting seat 510 puts the lifting plate 403 back on the bottom plate 401, and then the piston rod of the cylinder 503 is extended, causing the lifting seat 510 to withdraw from the lifting plate 403 and away from the sheet collector 4.

[0074] As shown in FIG5 , the unloading mechanism 6 includes a unloading base 601 , a lifting drive mechanism and a flipping drive mechanism.

[0075] The unloading base 601 is installed on the base 1, and can also be made into one piece with the base 1, and a left column 6011 and a right column 6012 are provided on it.

[0076] The lifting drive mechanism includes a motor 602, a screw rod 603, and a screw rod nut 604. The motor 602 is installed on the unloading base 601. The screw rods 603 are two oppositely arranged, and the upper end of each screw rod is rotatably supported by the left column 6011 and the right column 6012, respectively, and the lower end is rotatably supported by the unloading base 601. The screw rod nut 604 is sleeved on the outside of the screw rod 603, and the lifting seat 605 is installed on the screw rod nut. The motor 602 drives the intermediate transmission mechanism (not shown in the figure) to rotate at the same time, and drives the lifting seat 605 installed thereon to move up and down through their respective screw rod nuts 604.

[0077] Of course, the motor 602 and the intermediate transmission mechanism can also be installed in other places. This embodiment only provides a preferred structural arrangement.

[0078] The flip drive mechanism includes a motor 606, a driving wheel 607, a driven wheel 608, a chain, a flip frame 609, and a flip insertion rod 610. The motor 606, driving wheel 607, and driven wheel 608 are rotatably mounted on the lifting base 605. One end of the flip frame 609 is connected to a driven gear for rotation therewith, and the other end is rotatably connected to the lifting base 605. The flip insertion rod 610 is mounted on the flip frame 609 and spaced apart, corresponding to the insertion holes 4041 on the flip frame 404. The motor 606 drives the driving wheel 607 to rotate, which in turn drives the driven wheel 608 to rotate via a chain (not shown), thereby driving the flip frame 609 and the flip insertion rod 610 to rotate.

[0079] The flip frame 609 is provided with a plurality of flip support arms 6091 arranged at intervals. The flip support arms 6091 are perpendicular to the axis of the flip insertion rod 610 , so as to support the fin stack during flipping.

[0080] Since the fin stack is heavy, a slider and rail guide mechanism is provided to ensure that the lifting seat 605 can be lifted and lowered smoothly and has sufficient strength when flipping. The slider 611 is installed on the lifting seat 605, and the rails 612 are installed on the left column 6011 and the right column 6012 respectively.

[0081] The tilting drive mechanism also includes a plurality of baffles 613, each driven by a drive element, a cylinder 615. The cylinder 615 is mounted on a mounting frame 614, with its piston rod connected to the baffles 613. The mounting frame 614 is mounted on the left column 6011 and the right column 6012 at both ends. The piston rod can be extended and retracted to move the baffles 613 closer to or farther from the fin stack, thereby preventing the fin stack from tilting when the baffles 613 approach the fin stack.

[0082] At the unloading station, while the sheet collector 4 with the fin stack is moved from the inner turntable 2 to the base 1 by the sheet collector moving mechanism, the flipping rod 610 is gradually inserted into the plug hole 4041 on the flipping frame 404 until the sheet collector 4 stops moving, and then the lifting drive mechanism drags the flipping frame 404 and the fin stack thereon to rise until they are completely separated from the collecting needle 30, and the sheet collector moving mechanism pushes the remaining parts of the sheet collector 4 onto the inner turntable 2 again, and then the lifting drive mechanism drives the flipping frame 404 and the fin stack 10 thereon to descend. At the same time, the flipping drive mechanism drives the flipping frame 404 and the fin stack thereon to flip 90 degrees through the rotation of the flipping frame 609. In this way, the unloading speed can be increased by flipping while descending. After flipping into place, the special trolley 9 for receiving materials takes away the fin stack, and then the lifting drive mechanism drives the flip frame 404 to rise. At the same time, the flip drive mechanism drives the flip frame 404 to flip and reset through the rotation of the flip frame 609. After the flip frame 609 stops rising, the remaining parts of the chip collector 4 are moved from the inner turntable 2 to the base 1 by the chip collector moving mechanism. The lifting drive mechanism drives the flip frame 404 to descend and return to the lifting plate 403. The chip collector moving mechanism pushes the entire chip collector 4 onto the inner turntable 2 again. The inner turntable 2 rotates 180 degrees and returns to the collection station to prepare for the next collection. Example 2

[0083] The fin storage and retrieval machine of this embodiment differs from that of the first embodiment only in the flipping drive mechanism, and the remaining mechanisms are the same as those of the first embodiment.

[0084] As shown in Figure 8 , the flip drive mechanism of this embodiment includes a motor 66, a driving gear 67, a driven gear 68, a flip frame 609, and a flip rod 610. The motor 66 is connected to the driving gear 67, and the driven gear 68 meshes with the driving gear 67. Both ends of the flip frame 609 are rotatably connected to the lifting base 605, and one end is connected to the driven gear 68, which rotates together with the driven gear 68. The flip rod 610 is mounted on the flip frame 609 and is spaced apart. It corresponds to the insertion hole 4041 on the flip frame 404 (see Figure 2). When the flip drive mechanism is in operation, the motor 66 drives the driving gear 67 to rotate, and the driving gear 67 drives the driven gear 68 to rotate, thereby driving the flip frame 609 and the flip rod 610 to rotate.
