Description

Technical Field

[0001] This utility model relates to the field of electric heater tube processing technology, and in particular to an automatic fin collection and stacking device. Background Technology

[0002] In the process of processing electric heater heating tubes, in order to ensure the curing effect of the adhesive between the fins and the flat tube, the fins need to be cleaned and degreased first, and then the fins are collected and sent to the adhesive curing station.

[0003] In the existing processing flow, the cleaned and degreased fins need to be manually loaded into the trays. Some devices can automatically fill the trays with cleaned and degreased fins, but the empty trays still need to be placed on the filling station manually, and the full trays need to be manually removed.

[0004] The shortcomings of existing finned tray loading methods include: high labor intensity, low work efficiency, high labor costs, and potential safety hazards. Utility Model Content

[0010] In one preferred embodiment, the destacking and lifting assembly further includes a bottom positioning platform and a destacking limiting post connected together. The destacking limiting post is used to limit the lowest position of the lifting part. The output end of the drive cylinder passes through the bottom positioning platform and is connected to the support platform. The height of the destacking limiting post is greater than the height of the lifting support column.

[0011] In one preferred embodiment, the destacking system further includes a destacking upper sensor and a destacking lower sensor respectively disposed at both ends of the destacking bracket.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0036] This embodiment discloses an automatic fin collection and stacking device, such as... Figure 1 , Figure 2 , Figure 6 and Figure 8As shown, the automatic fin collection and stacking device includes an empty pallet position 100, a full pallet position 200, and a loading position 300. The loading position 300 is located between the empty pallet position 100 and the full pallet position 200. The empty pallet position 100 is equipped with a destacking system 1 for placing empty pallets 4, and the full pallet position 200 is equipped with a stacking system 2 for placing pallets 4 filled with fins 5. The loading position 300 is equipped with a tray loading system 3, which can load the cleaned fins 5 into the pallets 4 from the empty pallet position 100. After the pallets 4 are full, the loading position 300 sends the pallets 4 into the full pallet position 200.

[0037] This automatic fin collection and stacking device incorporates a destacking system 1 and a stacking system 2. It automatically retrieves empty pallets 4 from empty pallet positions 100, automatically loads fins 5 into the empty pallets 4, and automatically stacks the full pallets 4. Manual replenishment of empty pallets 4 to empty pallet positions 100 and removal of full pallets 4 from full pallet positions 200 are only required periodically. Frequent replenishment and removal of full pallets 4 reduces labor intensity and costs, resulting in high efficiency. It avoids the accumulation of dust and impurities caused by frequent operator proximity, maintaining the cleanliness of the fins 5 and eliminating the need for repeated cleaning, which wastes energy and materials. This contributes to energy conservation, emission reduction, and cost control. Reduced manual intervention lowers safety risks and material losses due to human error, eliminating potential safety hazards. It also reduces quality issues caused by inaccurate manual operation, thereby improving the overall quality of the final product. This automatic fin collection and stacking device enhances overall work efficiency and accuracy, achieving highly efficient and precise automated feeding with high consistency in pallet stacking.

[0038] To enhance automation, the automatic fin collection and stacking device also includes a control unit, enabling human-machine interaction and fully automated control of the entire process. This reduces manual operation, improving response speed and control precision, and enhancing operational convenience and safety. The control unit is connected to the depalletizing system 1, the stacking system 2, and the palletizing system 3, automatically filling empty pallets 4 before stacking them, thus improving production efficiency, reducing waiting time during production, and providing a better user experience.

[0039] In this embodiment, the control device can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control the depalletizing system 1, the stacking system 2, and the palletizing system 3 to achieve their functions. In this embodiment, the control device is a programmable logic controller (PLC), which has stable and mature performance and low cost.

[0040] The specific structure of the destacking system 1 is not limited; in this embodiment, for example... Figure 2 and Figure 3 As shown, the destacking system 1 includes a destacking bracket 11, a destacking clamping part 12, and a destacking lifting assembly 13. The destacking clamping part 12 for fixing the pallet 4 is disposed on the destacking bracket 11, and the destacking lifting assembly 13 is disposed below the destacking clamping part 12.

[0041] A stack of empty pallets 4 is placed on the destacking bracket 11. The destacking clamp 12 engages with the bottommost pallet 4, thus securing the stack of empty pallets 4 to the destacking bracket 11. The back plate and side rails of the destacking bracket 11 form a C-shape, preventing the stack of empty pallets 4 from moving laterally or tilting, making it safer to use. When an empty pallet 4 needs to be sent to the loading position 300, the destacking lifting assembly 13 first abuts against the bottommost pallet 4, and the destacking clamp 12 releases its grip on the bottommost pallet 4; the destacking lifting assembly 13 moves downward a set distance, so that the second-to-last pallet 4 aligns with the destacking clamp 12, and the destacking clamp 12 grips the second-to-last pallet 4, so that all pallets 4 in the second-to-last position and above are stabilized on the destacking bracket 11; the destacking lifting assembly 13 continues to move downward, so that the bottommost pallet 4 is separated from the other pallets 4, making it easier for the pallet 4 to be sent to the loading position 300.

[0042] The destacking system 1 can automatically send empty pallets 4 to the loading position 300, which is highly efficient. As long as they are within the height range of the destacking bracket 11, even a large number of pallets 4 can be stacked together stably, making pallet retrieval and placement more stable and reliable, and more convenient to use.

[0043] The specific structure of the destacking and lifting assembly 13 is not limited, as long as it enables the pallet 4 to move up and down. In this embodiment, for example... Figure 4 As shown, the destacking and lifting assembly 13 includes a drive cylinder 131, a guide shaft 132, a support platform 133, a lifting section 134, and a lifting support column 137. The lifting section 134 is used to lift the pallet 4 up or down. The main body of the drive cylinder 131 is connected to the guide shaft 132, which fixes the drive cylinder 131. The output end of the drive cylinder 131 is connected to the support platform 133. When the output end of the drive cylinder 131 moves, it can drive the support platform 133 to move along the extension direction of the guide shaft 132. The lifting support column 137 is set on the support platform 133. When the support platform 133 moves up and down, the lifting support column 137 can move synchronously. When the lifting support column 137 moves to a set position, it can abut against the lifting section 134. When it continues to move upward, it can drive the lifting section 134 to move synchronously along the extension direction of the guide shaft 132.

[0044] The lifting unit 134 is indirectly driven by the driving cylinder 131 to move up and down, so that the pallet 4 rises or falls. The overall structure is simple and reasonable. It can accurately control the moving distance of the pallet 4, ensuring that only one empty pallet 4 is taken out from a stack of pallets 4 each time, resulting in a better user experience, reduced manual intervention, and high work efficiency.

[0045] Based on the above structure, the destacking and lifting assembly 13 also includes a bottom positioning platform 136 and a destacking limit post 135 connected to each other. The output end of the drive cylinder 131 passes through the bottom positioning platform 136 and connects to the support platform 133. When the output end of the drive cylinder 131 moves downward, the lifting part 134 moves downward synchronously until the lifting part 134 abuts against the destacking limit post 135, at which point the lifting part 134 will no longer move downward with the output end of the drive cylinder 131. That is, the destacking limit post 135 limits the lowest position of the lifting part 134, preventing the lifting part 134 from moving downward too much, resulting in ineffective movement and wasting drive energy.

[0046] The height of the destabilizing post 135 is greater than the height of the lifting support column 137. After the lifting part 134 abuts against the destabilizing post 135, the lifting support column 137 and the support platform 133 can continue to move downward a certain distance with the output end of the drive cylinder 131. When the lifting part 134 needs to move upward, the output end of the drive cylinder 131 needs to drive the lifting support column 137 upward a certain distance before it abuts against the lifting part 134. This distance is used to eliminate problems such as unstable thrust when the drive cylinder 131 starts, ensuring that the drive cylinder 131 can smoothly push the lifting part 134 upward, and avoiding damage to the pallet 4 from the strong impact of the lifting part 134.

[0047] To accurately control the placement of the appropriate number of pallets 4 on the destacking bracket 11, such as Figure 2 As shown, the depalletizing system 1 also includes a depalletizing upper sensor 14 and a depalletizing lower sensor 15 respectively disposed at both ends of the depalletizing bracket 11. When the upper depalletizing upper sensor 14 has a signal, it indicates that there is still space on the depalletizing bracket 11, and more trays 4 can be placed. When the depalletizing bracket 11 is full of trays 4, the trays 4 are located between the signal transmitting end and the signal receiving end of the depalletizing upper sensor 14. When the depalletizing upper sensor 14 has no signal, information such as "No empty space on the depalletizing bracket 11" and "No more trays 4 can be placed" can be displayed.

[0048] Similarly, the lower destacking sensor 15 is used to determine whether there is a missing pallet 4 on the destacking bracket 11. Specifically, when there is a set number of pallets 4 on the destacking bracket 11 (which can be one, but is not limited to one), the pallet 4 is located between the signal transmitter and signal receiver of the lower destacking sensor 15, and the lower destacking sensor 15 has no signal. At this time, no pallet 4 needs to be placed on the destacking bracket 11. When the number of pallets 4 on the destacking bracket 11 is less than the set value, the pallets 4 can no longer block the signal transmitter and signal receiver of the lower destacking sensor 15, and the lower destacking sensor 15 has a signal. At this time, pallets 4 must be added to the destacking bracket 11 to avoid affecting the continuity of conveying pallets 4 to the upward material level 300.

[0049] The upper depalletizing sensor 14 and the lower depalletizing sensor 15 allow for precise control of the number of trays 4 on the depalletizing bracket 11. This prevents both excessive stacking of trays 4 causing the upper layer to fall off and situations where there are no usable trays 4 on the depalletizing bracket 11, making it more convenient to use. The upper depalletizing sensor 14 and the lower depalletizing sensor 15 can be connected to a buzzer, alarm light, or other structure to promptly issue an alert when the number of trays 4 on the depalletizing bracket 11 is insufficient, ensuring that there are always trays 4 available, resulting in a better user experience; reduced manual intervention, and lower labor intensity.

[0050] The specific placement of the upper destacking sensor 14 and the lower destacking sensor 15 is not limited, as long as they can detect the upper and lower limits of the stack of pallets 4 on the destacking bracket 11. The specific structure of the upper destacking sensor 14 and the lower destacking sensor 15 is not limited, and any existing detection sensor that can sensitively and accurately determine whether there are pallets 4 within the detection range can be used.

[0051] To improve the stability of pallet 4 on destacking bracket 11, such as Figure 2 and Figure 5 As shown, the pallet 4 has a slot 41, and the destacking clamping part 12 is provided with a retractable snap-fit ​​component. When the snap-fit ​​component extends, it can be inserted into the slot 41, thereby making the pallet 4 stably connected to the destacking clamping part 12; when the snap-fit ​​component retracts, the pallet 4 separates from the destacking clamping part 12, and the pallet 4 can be smoothly sent to the loading position 300.

[0052] Based on the above structure, the upper surface of the pallet 4 is provided with a limiting protrusion 42, and the lower surface of the pallet 4 is provided with a limiting recess 43. When the pallets 4 are stacked, the limiting protrusion 42 of the lower pallet 4 is inserted into the limiting recess 43 of the upper pallet 4, ensuring that a stack of pallets 4 can be stably positioned on the destabilizing bracket 11, and preventing the upper pallet 4 from moving laterally or tilting due to the lack of the destabilizing clamp 12.

[0053] The structure of stacking system 2 is similar to that of destacking system 1, such as... Figure 6 and Figure 7 As shown, the stacking system 2 includes a stacking support 21, a stacking clamping part 22, a stacking lifting assembly 23, a stacking upper sensor 24, and a stacking lower sensor 25. The stacking clamping part 22 for fixing the pallet 4 is disposed on the stacking support 21, the stacking lifting assembly 23 is disposed below the stacking clamping part 22, and the stacking upper sensor 24 and the stacking lower sensor 25 are respectively disposed at both ends of the stacking support 21.

[0054] The structure of the stacking lifting assembly 23 is basically the same as that of the destabilizing lifting assembly 13. Here, we will use the destabilizing lifting assembly 13 as an example: The pallet 4 filled with fins 5 at the loading position 300 is sent to the lifting section 134. The output end of the drive cylinder 131 moves the lifting section 134 upwards via the support platform 133 and the lifting column 137, causing the pallet 4 to abut against the lowest pallet 4 on the stacking support 21. The stacking clamping part 22 releases its grip on the lowest pallet 4, at which point the top... The lifting part 134 supports the pallet 4 from below, preventing both the newly delivered pallet 4 and the existing pallet 4 on the stacking support 21 from falling. The driving cylinder 131 causes the lifting part 134 to continue moving upward by a set distance. At this time, the newly delivered pallet 4 aligns with the stacking clamping part 22, and the newly delivered pallet 4 replaces the original bottom pallet 4, becoming the new bottom pallet 4. The stacking clamping part 22 engages the new bottom pallet 4, and the driving cylinder 131 drives the lifting part 134 to move downward, completing the stacking step.

[0055] The function of the upper stacking sensor 24 and the lower stacking sensor 25 is to monitor whether the pallets 4 on the stacking support 21 meet the requirements. When the upper stacking sensor 24 has no signal because its signal transmitter and receiver are blocked by the pallet 4, no new pallets 4 can be added to the stacking support 21 to prevent the upper pallets 4 from falling off due to the lack of restraint from the stacking support 21, and to prevent damage to the pallets 4 and the fins 5 located therein. The specific structure of the upper stacking sensor 24 and the lower stacking sensor 25 is not limited; any existing detection sensor that can sensitively and accurately determine whether a pallet 4 is within the detection range can be used.

[0056] Based on the above structure, such as Figure 8 and Figure 9 As shown, the tray loading system 3 includes a drive unit 31, an openable observation window 32, a tray loading bracket 33, a drive shaft 34, a limiting member 35, and a tray detector 36. The drive unit 31 can drive the drive shaft 34 to rotate, and the drive shaft 34 can drive the conveyor belt or conveyor wheel to work, thereby causing the tray 4 from the empty tray position 100 to move along the tray loading bracket 33 to the full tray position 200.

[0057] The intersection of the fin 5's movement path and the empty pallet 4's movement path is the receiving position, where the fin 5 can be loaded into the pallet 4. To prevent the pallet 4 from exceeding the receiving position without stopping, a limiter 35 is provided on the palletizing bracket 33. The arrival of the receiving position is determined when the pallet 4 abuts against the limiter 35. The pallet detector 36 is used to detect whether the pallet 4 has arrived at the receiving position, preventing the feeding of fins 5 from starting even when there is no pallet 4 at the receiving position. The observation window 32 is used to open or cover the receiving position, facilitating the operator's observation of the loading of fins 5 onto the pallet 4, making it more convenient to use. After the pallet 4 is full, the drive shaft 34 can transport the pallet 4 to the stacking system 2 via a conveyor belt or conveyor wheels.

[0058] The specific structure of the drive device 31 is not limited. In this embodiment, the drive device 31 is a stepper mechanism (or stepper motor). The drive device 31 can move the tray 4 according to preset parameters, so that the conveying speed and moving distance of the tray 4 match the feeding speed of the fins 5. This ensures the synchronization between the feeding of the fins 5 and the positioning of the tray 4, improves the feeding accuracy, reduces waiting time, and increases production efficiency. The specific structure of the tray detector 36 is not limited. Any precision detection sensor in the prior art that can accurately and quickly determine whether there is a tray 4 at the receiving position can be used.

[0059] Based on the above structure, such as Figure 8 and Figure 10 As shown, the automatic fin collection and stacking device also includes a cleaning conveying device 6 for conveying fins 5 to the upward material level 300. The cleaning conveying device 6 includes a cleaning conveying support 61 and a detection device 62. The cleaning conveying support 61 is provided with a cleaning conveying track 63 for the fins 5 to pass through, and the detection device 62 is used to determine whether there are fins 5 in the cleaning conveying track 63.

[0060] When the detection device 62 determines that there are fins 5 waiting to be palletized in the cleaning conveyor track 63, the pallet detector 36 detects that the empty pallet 4 has arrived at the receiving position, the cleaning conveyor track 63 transports the fins 5 into the pallet 4, and the drive device 31 moves the pallet 4 according to preset parameters until the pallet 4 is full. The cleaning conveyor track 63 stops transporting the fins 5, and the pallet 4 is sent to the stacking system 2.

[0061] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
