Description

TECHNICAL FIELD

[0001] The present application relates to a kind of aggregate racks. BACKGROUND

[0002] When producing air conditioner heat exchanger fins, generally through the aggregate rack with aggregate needle, the fins are stacked and then processed.

[0003] The existing aggregate rack generally includes a support plate, an aggregate needle mounting plate, a tray, a spacer sleeve, a guard plate, and an aggregate needle. Although it can complete the general aggregate function, it is inconvenient to move and cannot rotate, so there are problems of insufficient flexibility and limited function when cooperating with other mechanisms such as fin stamping processing devices and subsequent fin processing devices.

[0004] Therefore, the corresponding aggregate device composed of the existing aggregate rack has limited functions. For example, a two-station rotating aggregate device includes one aggregate station and one material taking station. After the aggregate station is full, the stamping machine stops. To avoid interference with the mold, the entire aggregate device first translates away from the punch press by a certain distance, moves into position, and then rotates 180 degrees to exchange positions through a rotating disc. After rotating into position, the entire aggregate device approaches the punch press, and then the aggregate station continues to aggregate. The stacked fins are moved to the taking station after rotation. To take the fins out of the aggregate rack without spreading, two long U-shaped tubes are inserted into each column of fin stacks by hand for positioning, and then the fin stacks are taken out one column at a time. When taking out the fins, the entire column of fins must be lifted above the top of the aggregate needle, and then they can be taken down and then laid flat. This process is labor-intensive, time-consuming, and very slow. When the aggregate height increases, each column of fins will become heavier, which requires more manual strength and limits the selection of workers. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the above-mentioned defects of the prior art and provide an aggregate rack that can be conveniently moved in a straight line and rotated at the same time.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0045] Example 1

[0046] like Figure 3 , 4 As shown, the movable material collection rack 4 includes a support plate 401, a material collection needle mounting plate 402, a tray 403, a spacer 405, a guard plate 406, a material collection needle 30, a pin 404, and a slider 407.

[0047] The collecting needle mounting plate 402 is mounted parallel to the support plate 401. The tray 403 is positioned above the collecting needle mounting plate 402, with a collecting needle through hole in the center and fixed plates 4031 around it. It is supported by a spacer 405. The lower part of the spacer 405 is mounted on the collecting needle mounting plate 402, and the upper part of the spacer 405 is inserted into the tray 403, separating the tray 403 from the collecting needle mounting plate 402. The collecting needle 30 is mounted on the collecting plate mounting plate 402 and passes upward through the collecting needle through hole in the center of the tray 403.

[0048] One end of the pin 404 is mounted on the center of the support plate 401, and the other end is inserted into the pin hole 4071 of the slider 407 located below it. In this way, the entire movable collection rack 4 can rotate on the slider 407 with the pin 404 as the center.

[0049] To prevent the material collection rack from rotating during movement, a movable positioning mechanism is provided between the slider 407 and the material collection rack 4. In this embodiment, the movable positioning mechanism includes a pin hole 4072 on the slider 407, spaced apart from the pin hole 4071, and a positioning cylinder 408. The piston rod of the positioning cylinder 408 extends and inserts into the other pin hole 4072. Therefore, when rotation of the material collection rack is not required, the piston rod of the positioning cylinder 408 extends and inserts into the other pin hole 4072. Since there are two positioning points between the material collection rack 4 and the slider 407, they remain relatively stationary. When rotation of the material collection rack is required, the piston rod of the positioning cylinder 408 can be retracted, leaving only one positioning point between the material collection rack 4 and the slider 407: the pin shaft 404. Therefore, the material collection rack 4 can rotate around the pin shaft 404.

[0050] The fixed plate 4031 is also vertically mounted with guard plates 406 around it. When the movable collection rack 4 receives the fins, it can first lift the tray 403. The guard plates 406 can guide the fins on the one hand, and straighten and clamp the fins piled on the tray 403 on the other hand.

[0051] The side of the fixed plate 4031 is also provided with lifting parts 4032 and 4032' that cooperate with the support part of the lifting drive mechanism 8 described below. The lifting drive mechanism 8 can lift the entire tray 403 and the fins placed on the tray 403 through the support part, lifting parts 4032 and 4032', thereby separating the fixed plate 4031 from the integrated support plate 401, the collecting needle mounting plate 402 and the collecting needle. Alternatively, the tray 403 can be placed back onto the integrated support plate 401, the collecting needle mounting plate 402 and the collecting needle to form a collecting rack with the tray 403 again.

[0052] The side of the guard plate 406 is also provided with guide posts 4061 and 4061', which can be used to guide the front guide posts 4061' on the two sides (see Figure 10The entire tray 403 and guard plate 406 are rotated around the center of rotation, with the rear guide posts 4061 on both sides as force points, and finally placed sideways on the base 1. This facilitates operations such as inserting tubes into the fin stack. In this embodiment, the front guide post 4061' cooperates with the bracket 102 set on the base 1 as the center of rotation, and the rear guide post 4061 cooperates with the rear hook 8041 of the lifting drive mechanism 8. The lifting drive mechanism 8 raises the tray 403 and guard plate 406 so that they are rotated and placed sideways on the base 1.

[0053] The aforementioned mobile collection rack can move in a straight line and rotate during movement, thus it can be flexibly applied to various collection devices.

[0054] In this embodiment, the material collection device includes the aforementioned movable material collection frame 4, base 1, inner turntable 2, and rotary drive mechanism. The inner turntable 2 and rotary drive mechanism are mounted on the base 1. The inner turntable 2 is connected to the rotary drive mechanism, which drives the turntable 2 to rotate relative to the base 1 by a set angle. Figures 1-13 .

[0055] like Figure 2 As shown, the rotary drive mechanism includes: a motor 301, a drive gear 302, and a large gear 303; the motor 301 is mounted on the base 1, and the drive gear 302 is mounted on its output shaft. The large gear 303 is supported by the base 1 by rolling. The drive gear 302 meshes with the large gear 303, and the inner turntable 2 is mounted on the large gear 303; thus, the motor 301 drives the drive gear 302 to rotate, and then the large gear 303 drives the inner turntable 2 mounted on it to rotate. The rotation angle is determined according to actual needs, such as the number of workstations and the interval between workstations as required.

[0056] To ensure smooth movement of the mobile collection rack, the base 1 is provided with a groove 101 that mates with the slider 407 at the bottom of the mobile collection rack 4. The inner turntable 2 is also provided with a turntable groove 201 corresponding to the groove 101. The slider 407 can move within the grooves 101 and 201. Thus, the mobile collection rack 4 can be moved along the grooves 101 and 201 by extending and retracting the piston rod of the cylinder 5, allowing the slider 407 to move onto the base 1 or the inner turntable 2. Then, by rotating the inner turntable 180 degrees, the positions of the collection rack at the collection station and the collection rack at the picking station are exchanged.

[0057] A reversing mechanism is also provided, which includes a reversing cylinder 7 and a steering groove 701. The reversing cylinder 7 is mounted on the support plate 401, and the steering groove 701 is located at the material handling station of the base 1. Figure 1It is a long straight groove at an angle to the moving direction of the slider 407. After the piston rod of the reversing cylinder 7 extends and is inserted into the reversing groove 701, the material collection rack 4 will rotate around the pin shaft 404 under the guidance of the long straight groove, and finally drive the material collection rack 4 to rotate 90 degrees to achieve the entire reversal.

[0058] like Figure 3 As shown, the rotary drive mechanism includes: a motor 301, a drive gear 302, and a large gear 303; the motor 301 is mounted on the base 1, and the drive gear 302 is mounted on its output shaft. The large gear 303 is supported by the base 1 by rolling. The drive gear 302 meshes with the large gear 303, and the inner turntable 2 is mounted on the large gear 303; thus, the motor 301 drives the drive gear 302 to rotate, and then the large gear 303 drives the inner turntable 2 mounted on it to rotate. The rotation angle is determined according to actual needs, such as the number of workstations and the interval between workstations as required.

[0059] It also includes a pallet lifting drive mechanism 6, which is symmetrically arranged on the material collection station of the base 1, near the punch press side, such as... Figure 1 As shown, it includes a motor 601, a transmission mechanism, a lead screw 602, a lead screw nut 603, and a pallet 604. The motor 601 is mounted on the base 1. The upper and lower ends of the lead screw 602 are respectively supported by protective support seats 605. The lead screw nut 603 is sleeved on the lead screw 602. The two ends of the pallet 604 are respectively connected to a lead screw nut 603. The motor 601 drives the transmission mechanism to rotate all four lead screws 602, which in turn drives the pallet 604 to rise or fall through the lead screw nuts 603. When the movable collection rack 4 moves to the collection station, so that the two ends of its fixing plate 4031 overlap the pallet 604, the pallet 403 can be raised or lowered.

[0060] The transmission mechanism is a sprocket drive mechanism, but it can also be a belt drive mechanism, etc. This embodiment uses a sprocket drive mechanism. Figure 5 As shown, the sprocket drive mechanism includes: a drive sprocket 606, a sprocket 607, an intermediate sprocket 608, and a chain 609. The sprockets are connected and driven by the chain 609, and each sprocket 607 is mounted on a lead screw 602.

[0061] It also includes another lifting drive mechanism 8 for separating the tray and the collecting needle. This drive mechanism comprises two sets, symmetrically arranged at the material handling station of the base 1, such as... Figure 1 As shown, it includes a motor 801, a transmission mechanism, a lead screw 802, a lead screw nut 803, and a support plate 804.

[0062] The motor 801 is mounted on the base 1 and is connected to two lead screws 802 through a transmission mechanism, which drives the two lead screws 802 to rotate.

[0063] The transmission mechanism is a sprocket transmission mechanism, which includes a sprocket mounted on the output shaft of motor 801 and a sprocket mounted on the lower end of two lead screws. The sprockets are connected and driven by a chain. For details, please refer to the sprocket transmission mechanism of the pallet.

[0064] The upper and lower ends of the lead screw 802 are respectively supported by the protective support seat 805. The lead screw nut 803 is sleeved on the outside of the lead screw 802. The two ends of the support plate 804 are respectively connected to a lead screw nut 803, and hooks 8041 and 8041' that cooperate with the lifting blocks 4032 and 4032' are provided on it.

[0065] It also includes a translation mechanism 9 set at the material picking station. The translation mechanism 9 includes a translation drive mechanism, a translation transmission mechanism and a connecting mechanism. The connecting mechanism is connected to the lifting drive mechanism 8. The translation drive mechanism is connected to and drives the connecting mechanism to move through the translation transmission mechanism and the connecting mechanism, thereby causing the lifting drive mechanism 8 to translate. In this embodiment, the translation drive mechanism is a motor 901, and the translation transmission mechanism includes pulleys 903 and 904, a transmission shaft 905, pulleys 906, 907, 908, and a transmission belt 910. The connecting mechanism is a screw. The motor is mounted on the base 1, and pulley 902 is mounted on its output shaft. The two ends of the transmission shaft 905 are rolledly supported by the base 1, and pulleys 903, 904, and 906 are mounted on it. The pulleys 908 and 907 are respectively mounted on short shafts 909 that are rolledly supported by the base 1 at both ends. The pulleys 902 and 903, pulleys 904 and 908, and pulleys 906 and 907 are connected and driven by belts. The transmission belt 910 is connected to the lower end of the protective support seat 805 of the lifting drive mechanism 8 by screws (not shown). Thus, the motor 901 drives the pulley on it to rotate, and through the transmission of pulleys 903, 904 and 906, the transmission belt 910 drives the protective support seat 805 to move, thereby driving the entire lifting drive mechanism 8 to move horizontally.

[0066] To ensure smooth movement of the protective support 805, a slider guide mechanism is added between the base 1 and the protective support 805. The slider 911 of the slider guide mechanism is mounted on the protective support 805, and the slide rail 912 of the slider guide mechanism is mounted on the base 1.

[0067] Using the above-mentioned material collection mechanism, the following fin material collection and retrieving processes can be performed.

[0068] 1. During material collection, two movable material collection frames 4 are located at the material collection station and the material picking station, respectively. The piston rod of the positioning cylinder 408 extends and inserts into the pin hole 4072. The two ends of the fixing plate 4031 of the material collection frame 4 at the material collection station overlap the pallet 604. The pallet lifting drive mechanism 6 drives the pallet 403 to rise to the designated position above the material collection needle 30. As the fins accumulate, the pallet 403 descends intermittently until it is full and stops at the set position, ensuring the smooth completion of fin stacking. Because the material collection needle is thin and long, it will tilt to varying degrees in a vertical state. To make it easier for the fins to fall, the aforementioned pallet 403 and pallet lifting mechanism 6 are set. After material collection is completed, the piston rods of the two cylinders 5 retract, moving the two movable material collection frames 4 onto the inner turntable 2, as shown. Figure 7 As shown.

[0069] 2. The rotary drive mechanism drives the inner turntable 2 to rotate 180 degrees. The piston rods of the two cylinders 5 extend, pushing the empty collection rack 4 from the inner turntable 2 to the collection station on the base 1 and stopping it. Then, the collection begins. The collection rack 4, filled with fins, is pushed towards the picking station. When it reaches above the guide groove 701, the piston rod of the positioning cylinder 408 exits the pin hole 4072. At the same time, the piston rod of the reversing cylinder 7 extends and inserts into the guide groove 701. Under the pushing of the cylinders 5 and the action of the reversing mechanism, the collection rack 4, filled with fins, is rotated 90 degrees and stops moving. Figure 8 As shown.

[0070] 3. The translation mechanism 9 of the material handling station drives the lifting drive mechanism 8 to move. After moving into position, the hooks 8041 and 8041' support the lifting blocks 4032 and 4032'. Then, the lifting drive mechanism 8 drives the pallet 403 and the finned plate to rise. After separating from the collecting needle, the rising stops. Figure 9 As shown.

[0071] 4. The piston rod of the cylinder 5 at the material handling station retracts, returning the material collection rack 4 to the inner turntable 2 to wait. Then, the lifting drive mechanism 8 drives the pallet 403 and the finned plate to descend. Figure 10 As shown, until the fixing plate 4031 and tray 403 are placed on the base 1, the hook 102 installed on the base 1 supports the guide column 4061', and then the hooks 8041 and 8041' continue to descend until they stop disengaging from the lifting blocks 4032 and 4032'. The translation mechanism 9 moves a certain distance, causing the hook 8041 to rise and support the guide column 4061. Then the lifting drive mechanism 8 continues to rise, and under the action of the guide columns 4061 and 4061', the tray 403 and the finned plate are rotated 90 degrees outward. The lifting drive mechanism 8 then stops. Figure 11As shown, the fin stack is then removed. For example, in the following embodiment, the fin stack along with the collecting needle is rotated 90 degrees horizontally and pushed to the material handling station. After the positioning long U-tube is manually inserted, the fin stack and collecting needle automatically separate. The collecting needle can then be moved to the inner turntable, and the fin stack can be rotated 90 degrees outward to lower it for unloading. This unloading method eliminates the need to lift the fin stack away from the collecting needle before unloading, saving time and effort. It also facilitates connection to other receiving devices, allowing the entire fin stack to be moved from the collecting device to the next process without requiring the entire collecting device to be moved.

[0072] 5. After the fins are removed, the lifting drive mechanism 8 descends, placing the empty pallet 403 and fixing plate 4031 flat on the base 1. It continues to descend until the hook 8041 disengages from the guide post 4061 and stops. The translation mechanism 9 moves in the opposite direction a certain distance, and the lifting drive mechanism 8 rises, causing the hooks 8041 and 8041' to support the lifting blocks 4032 and 4032'. It continues to rise until it reaches a height where the collecting needle can pass through. The piston rod of the cylinder 5 at the material handling station extends, pushing the collecting rack 4 from the inner turntable 2 onto the base 1 and rotating it 90 degrees. Figure 12 As shown in the diagram, the lifting drive mechanism 8 then lowers the pallet 403 back onto the collection rack.

[0073] 6. The piston rod of cylinder 5 at the material handling station retracts, moving the empty material collection rack to the inner turntable to wait (e.g., Figure 13 As shown), when the material collection rack at the material collection station is full of fins, the piston rod of the cylinder 5 connected to it retracts, moving the material collection rack 4 full of fins onto the inner turntable 2.

[0074] 7. Then rotate the inner turntable 2 180 degrees and repeat steps 2-6 above.

[0075] Example 2

[0076] Example 2 makes minor changes to Example 1. The active positioning mechanism (positioning cylinder 408 and pin hole 4072) of the collecting device is removed. The reversing cylinder 7 of the reversing mechanism is replaced with a studded needle roller bearing 7' that passes through and is mounted on the support plate 401. The steering groove 701 on the base 1 of the material handling station is replaced with a steering groove 701'. The studded needle roller bearing 7' moves within the steering groove 701', and a groove 207 connected to the steering groove 701' and capable of accommodating the studded needle roller bearing 7' is provided on the inner turntable 2. Figure 15 As shown.

[0077] Using the above-mentioned material collection mechanism, the following fin material collection and retrieving processes can be performed.

[0078] 1. Same working process as in Example 1.

[0079] 2. The rotary drive mechanism drives the inner turntable 2 to rotate 180 degrees, such as... Figure 15As shown. The piston rods of the two cylinders 5 extend and push the empty material collection rack 4 from the inner turntable 2 to the material collection station of the base 1 to stop, and start material collection. The material collection rack 4 filled with fins is rotated 90 degrees by the reversing mechanism and pushed to the material picking station.

[0080] 3. The rest of the working process is the same as in Example 1.

[0081] Example 3

[0082] Example 3 makes minor changes to Example 1. The movable positioning mechanism (positioning cylinder 408 and pin hole 4072) is removed from the collecting device. The reversing cylinder 7 of the reversing mechanism is replaced with a stud roller bearing 7' that passes through and is mounted on the support plate 401. The steering groove 701 on the material handling station base 1 is replaced with a steering groove 701' on the collecting station base 1. The stud roller bearing 7' moves within the steering groove 701', and a groove 207, continuous with the steering groove 701', is provided on the inner turntable 2 to accommodate the stud roller bearing 7'. Figure 14 As shown. Since the positioning cylinder 408 and the reversing cylinder 7 require ventilation pipelines to operate, and also need to meet the movement and rotation requirements during workstation changes, the arrangement of the ventilation pipelines presents certain difficulties. However, the solution in this embodiment can avoid this problem.

[0083] Using the above-mentioned material collection mechanism, the following fin material collection and retrieving processes can be performed.

[0084] 1. The working process is the same as in Example 1, except that when the piston rod of cylinder 5 retracts, the material collection rack 4 of the material collection station is rotated 90 degrees and moved to the inner turntable 2 by moving along the trajectory of the steering groove 701' through the reversing mechanism stud roller bearing 7'.

[0085] 2. The rotary drive mechanism drives the inner turntable 2 to rotate 180 degrees. The piston rods of the two cylinders 5 extend, and the empty material collection rack 4 is rotated 90 degrees from the inner turntable 2 through the reversing mechanism and pushed to the material collection station of the base 1 to stop, and the material collection begins. The material collection rack 4 filled with fins is pushed to the material picking station.

[0086] 3. Same working process as in Example 1.

[0087] 4. Same working process as in Example 1.

[0088] 5. The working process is the same as in Example 1, except that the empty material rack waiting on the inner turntable 2 does not need to rotate 90 degrees to return to the inner turntable.

[0089] 6. The working process is the same as in Example 1, except that the empty material collection rack at the material picking station does not need to rotate 90 degrees to return to the inner turntable, and the material collection rack 4 at the material collection station is rotated 90 degrees to move to the inner turntable 2.

[0090] 7. Then rotate the inner turntable 2 180 degrees and repeat steps 2-6 above.

[0091] Example 4

[0092] like Figure 16 , 17 As shown, Embodiment 4 makes a minor change to Embodiment 1. The middle part of the tray 403 is provided with protrusions 4033 at both ends. Positioning pins 4034 are installed on the protrusions 4033. The tray 403 is connected to the tray 604 by inserting the positioning pins 4034 into the pin holes (not shown in the figure) of the tray 604.

[0093] When collecting materials, the pallet 604 of the pallet lifting drive mechanism 6 can only drive the pallet 403 to rise first, and then gradually lower the material to collect it. In this way, the fixed plate 4031 and the guard plate 406 will not rise with the pallet 403, avoiding interference with the suction device of the punch press that produces fins. After the material collection is completed, the pallet can continue to fall a certain distance to separate the pallet 403 and the pallet 604.
