Description

Technical Field

[0001] The present invention relates to the technical field of profile transportation and stacking, and particularly to a stacking device for aluminum profile processing. Background Art

[0002] Aluminum profiles are made of aluminum and other alloy elements. First, they are processed into tubular profiles, and then through processes such as cold bending, sawing, drilling, assembling, and coloring to form the final products. Profiles of different specifications and models need to be stored separately to facilitate subsequent processing and management.

[0003] Currently, manual stacking is still the mainstream method for profile stacking, which is carried out on flat brackets or simple supports. However, in this simple stacking method, the aluminum profiles are placed disorderly, resulting in an unreasonable force structure, limited stacking layers, low space utilization rate, and the profiles at the bottom are prone to compressive deformation. For automatic or semi-automatic profile stacking, robotic arms are mostly used to clamp the profiles, which is likely to cause relatively large physical contact force between the profiles, and small depressions are likely to appear on the surface of the profiles. For profiles that need to be colored on the surface, scratches are also likely to be generated, reducing the quality of the profile products. For profiles with rollers, the main way is to gather the profiles by rolling. When the profiles are rolling, they are also likely to scrape against the brackets, and when the profiles fall, collisions occur, which are also likely to damage the surface of the profiles.

[0004] Therefore, it is necessary to develop a stacking device for aluminum profile processing to solve the above problems. Summary of the Invention

[0005] The present invention provides a stacking device for aluminum profile processing to solve the defects in the prior art that manual stacking is uneven, the stacking layers are limited, the profiles at the bottom are easily squeezed and deformed, and the robotic arm clamping is likely to damage the surface of the profiles.

[0006] The present invention provides a stacking device for aluminum profile processing, including:

[0007] An aluminum profile conveying assembly, including a plurality of profile arranging conveying platforms and a plurality of profile delivering transfer platforms arranged at intervals. The profile arranging conveying platforms and the profile delivering transfer platforms have the same transmission direction and overlap in the transmission stroke. The conveyor belts on the profile arranging conveying platforms and the profile delivering transfer platforms are belts with adhesiveness on the surface; a spacer transporting assembly, including a spacer conveying platform and a spacer delivering mechanism. The spacer delivering mechanism is used to deliver the prepared spacers to the spacer conveying platform, and the spacer conveying platform is used to arrange a plurality of spacers at intervals along the arrangement direction of the profile delivering transfer platforms.

[0008] In a further embodiment, the palletizing device for aluminum profile processing further includes a hoisting frame, and a pallet grabbing mechanism is arranged on the hoisting frame. The pallet grabbing mechanism is configured to place aluminum profiles at intervals on a layer of arranged pallets, then lift the pallets and stack them at a set position.

[0009] In a further embodiment, the pallet delivery mechanism includes a pallet delivery frame arranged along the arrangement direction of the profile delivery transfer table. The pallet delivery frame is located outside the hoisting frame. On the inner bottom of the pallet delivery frame, a pallet delivery transfer table for cooperating with the pallet conveyor table is arranged on the side close to the profile arrangement conveyor table. A delivery bracket is arranged on the side of the pallet delivery frame close to the profile arrangement conveyor table, and a liftable pallet delivery clamp is arranged on the top of the pallet delivery frame. On the other side of the inner bottom of the pallet delivery frame where the pallet delivery transfer table is arranged, it is used to stack the prepared pallets layer by layer. The pallet delivery clamp is used to transport the stacked pallets layer by layer to the pallet delivery transfer table, and the delivery bracket is used to transport the pallets on the pallet delivery transfer table to the pallet conveyor table one by one.

[0010] In a further embodiment, the pallet grabbing mechanism includes a lifting mounting frame arranged on the hoisting frame. A number of uniformly distributed pallet clamps are fixedly connected to both sides of the lifting mounting frame along the transmission direction of the profile arrangement conveyor table. The pallet clamps are used to grab the pallets arranged on the pallet conveyor table, and the lifting mounting frame is used to drive the pallet clamps to lift and reciprocate along the transmission direction of the profile arrangement conveyor table.

[0011] In a further embodiment, bases are arranged at the bottoms of the profile arrangement conveyor table and the profile delivery transfer table. The bases are used to support and install the profile arrangement conveyor table and the profile delivery transfer table. Profile positioning electric rods are fixedly connected to the sides of the profile arrangement conveyor table far from the pallet delivery mechanism, and the output ends of the profile positioning electric rods are lifted synchronously.

[0012] In a further embodiment, when the profile positioning electric rod is fully extended, its output end is higher than the aluminum profiles on the profile arrangement conveyor table. When the profile positioning electric rod is fully retracted, its output end is lower than the surface of the conveyor belt on the profile arrangement conveyor table. The profile arrangement conveyor table and the profile delivery transfer table are synchronously driven, and the transmission surfaces of the profile arrangement conveyor table and the profile delivery transfer table are at the same height.

[0013] In a further embodiment, the pallet clamp includes a mounting shell fixedly connected to the lifting mounting frame. Two mutually meshing incomplete gears are arranged inside the mounting shell along the arrangement direction of the profile delivery transfer table. The incomplete gears are both rotatably connected inside the mounting shell, and an L-shaped grabbing clamp is fixedly connected to the bottom of the incomplete gear. The grabbing clamps approach or move away from each other within the opening at the bottom of the mounting shell.

[0014] In a further embodiment, the thickness of the bottom chuck of the grasping clip is less than the height of the backing plate. When the grasping clip is closed, the chucks at its bottom are aligned with each other to completely overlap; when the grasping clip is opened, the backing plate can pass through the gap between the bottom chucks of the grasping clip.

[0015] In a further embodiment, an electromagnet is provided at the bottom of the backing plate delivery clip. The backing plates are arranged in the middle on the backing plate delivery rack and the backing plate conveyor table. The aluminum profiles arranged and completed on the profile conveyor table are located at the middle position of the backing plates on the backing plate conveyor table.

[0016] In a further embodiment, both the profile arranging conveyor table and the profile delivery transfer table are located inside the hoisting rack. A stacking rack is provided inside the hoisting rack on one side of the profile arranging conveyor table away from the profile delivery transfer table. The backing plates and the aluminum profiles are stacked in an alternating layer arrangement on the stacking rack.

[0017] A palletizing device for aluminum profile processing provided by the present invention has the following technical effects or advantages:

[0018] 1. Through the staggered distribution between the profile delivery transfer table and the profile arranging conveyor table, their starting and stopping cooperate with each other to continuously convey and arrange the aluminum profiles. The backing plate conveyor table and the backing plate delivery mechanism are used to convey and arrange the backing plates placed at the bottom of the profiles, which is convenient for improving the stacking uniformity; the extrusion on the bottom profiles caused by stacking is dispersed, reducing the deformation of the profiles.

[0019] 2. The conveyor belts on the profile delivery transfer table and the profile arranging conveyor table can be replaced according to whether the profiles are prone to rolling. The rolling of the profiles is prevented by the adhesiveness of the belt surface, and it can be applied to more different types of profiles; the conveying and arranging of the backing plates and the profiles are carried out synchronously, with a higher degree of automation and labor saving.

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts fall within the scope of protection of the present invention.

[0035] As described above, when stacking profiles, manual arrangement easily leads to limited stacking layers, low space utilization rate, and insufficient uniformity of profile distribution, which easily causes the profiles at the bottom to be deformed under pressure. When automatically or semi-automatically stacking profiles, it is mostly the robotic arm that grips the profiles, and physical contact with a relatively large contact force is likely to occur between the equipment and the profiles. Microscopic depressions are likely to appear on the surface of the profiles, and scratches are also likely to occur on the profiles that need to be colored on the surface, which will reduce the quality of the finished profiles. When stacking some profiles that can roll during transportation due to their shape, the profiles gather together by rolling on their own. The rolling of the profiles easily results in the phenomenon that the two ends contact successively, causing the pipe ends to be misaligned. Moreover, when the profiles are rolling, they are also likely to scrape against the brackets, and the collisions generated when the profiles fall are also likely to cause damage to the surface of the profiles.

[0036] In response to this, the present invention provides a palletizing device for aluminum profile processing, which can, through the staggered distribution between the profile delivery transfer table 102 and the profile arrangement transfer table 101, with their start and stop cooperating with each other, continuously convey the profiles. By using the rotation of the profile arrangement transfer table 101 and the profile positioning electric rod 8 to uniformly adjust the spacing between the profiles, the stacking uniformity is improved, the space utilization rate and stacking height of the stacking are increased, the placement is more uniform, and the extrusion on the bottom profiles caused by stacking can also be dispersed, reducing the plastic deformation of the profiles. Using the cushion plate as the contact with the profiles reduces the direct physical contact between the equipment and the profiles and reduces the damage to the surface of the profiles. It can also replace the belts on the profile delivery transfer table 102 and the profile arrangement transfer table 101 according to whether the profiles will roll during the arrangement and transportation process, increasing the applicability of the palletizing device to the transportation and stacking of different profiles.

[0037] The following combines Figures 1 to 11 Specifically describe the present invention.

[0038] First Embodiment:

[0039] As Figures 1 to 10 shown, the present invention provides a palletizing device, especially a palletizing device for aluminum profile processing. In this embodiment, the palletizing device mainly includes an aluminum profile conveying assembly 1, a cushion plate conveying assembly 2, a hoisting frame 3, a cushion plate delivery mechanism 4, and a cushion plate grasping mechanism 5. As Figure 1As shown in the figure, spatial coordinates are defined in the figure: the X-axis, the Y-axis, and the Z-axis, and their positive directions are specified, and their actual meanings can be customized. The hoisting frame 3 serves as the basis for hoisting the neatly arranged profiles. At both sides of the top of the hoisting frame 3 along the X-axis direction, a T-shaped cross beam is fixedly connected, and a moving support is arranged on the cross beam. The two ends of the moving support along the X-axis direction can reciprocate along the Y-axis direction through the slide rails arranged on the upper side of the cross beam. At both positions of the bottom of the moving support along the two ends of the X-axis, a hoisting telescopic rod is arranged. Inside the hoisting frame 3, a lifting mounting frame 501 is arranged along the negative Z-axis direction. The two ends of the top of the lifting mounting frame 501 distributed along the X-axis are respectively fixedly connected to the telescopic ends of the two hoisting telescopic rods. By the telescoping of the hoisting telescopic rod, the lifting of the lifting mounting frame 501 is controlled. On both sides of the lifting mounting frame 501 along the Y-axis direction, a backing plate clamp 6 is arranged. The backing plate to be lifted is clamped by the backing plate clamp 6, and the backing plate together with the profile is lifted. First, it is lifted in the positive Z-axis direction, and then it is moved in the positive Y-axis direction. At the bottom of one end of the hoisting frame 3 along the positive Y-axis direction inside, a stacking rack 9 is arranged. The backing plate clamp 6 stacks the neatly arranged profiles and the backing plate together on the stacking rack 9 to form a uniform stack of one layer of backing plates and one layer of profiles.

[0040] As Figure 4 and Figure 5 shown, the backing plate clamp 6 mainly includes: a mounting housing 601, an incomplete gear 602, and a grasping clamp 603. Among them, a number of mounting housings 601 are evenly distributed and fixedly connected to the lifting mounting frame 501, and are respectively fixedly connected to both sides of the lifting mounting frame 501 distributed along the Y-axis, and are symmetrically distributed. The mounting housing 601 is adjusted and installed according to the spacing and position of the backing plate to be clamped, and is fixed after installation. Inside each mounting housing 601, two meshing incomplete gears 602 are arranged along the X-axis direction. At the bottom of the two incomplete gears 602 inside the same mounting housing 601, a grasping clamp 603 is fixedly connected. The rotation of the two incomplete gears 602 can drive the grasping clamps 603 to approach or move away from each other. The grasping clamps 603 extend out from the opening at the bottom of the mounting housing 601. The clamping heads at the lower ends of the two grasping clamps 603 cooperate with each other. After the two grasping clamps 603 are closed, in the clamped state, the two clamping heads at the bottom can be closed. The two incomplete gears 602 inside the same mounting housing 601 are rotatably connected to the two side walls inside the mounting housing 601 along the Y-axis direction. As Figure 4 shown, a motor can be fixedly connected to the outside of the mounting housing 601 away from the lifting mounting frame 501. The output end of this motor is fixedly connected to the rotating shaft of one of the incomplete gears 602. Through the meshing of the incomplete gears 602, the other incomplete gear 602 is driven to swing in the opposite direction, and the two grasping clamps 603 are closed to complete the clamping operation.

[0041] A base 7 is provided at each of the middle part inside the hoisting rack 3 and the side far from the stacking rack 9. A backing plate conveying table 201 is provided on the middle base 7. The conveying direction of the backing plate conveying table 201 is along the negative direction of the X-axis. The backing plate conveying table 201 conveys the backing plates arranged at equal intervals thereon in the negative direction of the X-axis. The backing plates are placed in the middle of the backing plate conveying table 201, and both ends of the backing plates extend out of the backing plate conveying table 201. Inside the backing plate is a metal hollow plate with a small deformation amount and magnetism. The outside of the metal hollow plate is wrapped with a soft contact layer. The contact layer can be composed of a sponge wrapped with a leather material on the outside. The outer surface of the contact layer has an anti-slip function to prevent relative sliding between the profiles and the backing plate when lifting the neatly stacked profiles. After the conveyor belt surface on the backing plate conveying table 201 transports a certain distance in the negative direction of the X-axis, the conveying stops. After a new backing plate is fed into one end of the backing plate conveying table 201 in the positive direction of the X-axis, it moves backward continuously to make the backing plates on the backing plate conveying table 201 arranged at equal intervals. Finally, the positions of the backing plates are aligned with the backing plate clamps 6 on the lifting and mounting frame 501 one by one.

[0042] The aluminum profile conveying assembly 1 further includes a plurality of profile arranging and conveying tables 101 provided on the middle base 7. The profile arranging and conveying tables 101 are located in the positive direction of the Z-axis of the backing plate conveying table 201. The profile arranging and conveying tables 101 are fixedly connected to the base through supports on the middle base, and the profile arranging and conveying tables 101 are arranged at equal intervals along the X-axis direction. The conveying direction of the conveyor belt on the profile arranging and conveying tables 101 is along the positive direction of the Y-axis, which is the direction towards the stacking rack 9, and the conveying direction of the profile arranging and conveying tables 101 can make a short-distance rotation in the negative direction of the Y-axis. A plurality of equally spaced profile delivering and conveying tables 102 are provided on the other base 7. The arranging direction of the profile delivering and conveying tables 102 is along the X-axis, and the conveying direction of the conveyor belt on the profile delivering and conveying tables 102 is the same as that of the profile arranging and conveying tables 101. There is an overlap in the conveying strokes of the profile arranging and conveying tables 101 and the profile delivering and conveying tables 102. The aluminum profiles on the profile delivering and conveying tables 102 can be in the conveying stroke of the profile arranging and conveying tables 101 before completely leaving their surfaces.

[0043] The profile delivering and conveying tables 102 are also fixedly connected to the base through the supports on the base 7. The conveying surfaces of the profile delivering and conveying tables 102 and the profile arranging and conveying tables 101 are on the same horizontal plane. In this embodiment, taking the profile delivering and conveying tables 102 being on the side of the profile arranging and conveying tables 101 along the negative direction of the X-axis as an example, the conveying leaving end of the profile delivering and conveying tables 102 is between the intervals of the conveying entering end of the profile arranging and conveying tables 101. The conveyor belts on the profile delivering and conveying tables 102 are synchronously conveyed, and the belts on the profile arranging and conveying tables 101 are also synchronously conveyed.

[0044] In order to realize the synchronous transmission of the conveyor belt on the profile delivery and conveying platform 102 and the synchronous transmission of the belt on the profile arrangement and conveying platform 101, the driving wheels for driving the belts on the profile arrangement and conveying platforms 101 need to rotate synchronously. Figure 8 and Figure 9 As shown, a driven roller is rotatably connected to one side of the profile arrangement conveyor 101 along the negative direction of the X-axis, and the rotating shaft of the driven roller and the driving wheel rotating shaft of the belt of the profile arrangement conveyor 101 are fixedly connected together, and the driving wheel is driven to rotate by the driven roller. In order to drive the driven wheel to rotate, a long rotating shaft is clamped on the support of the base through a protrusion, and a number of evenly distributed driving rollers are fixedly connected to the long rotating shaft. The driving roller and the driven roller are connected by a meshing belt to ensure that there is no slippage between the driving roller and the driven roller. The long rotating shaft is driven by a motor arranged on the profile arrangement conveyor 101 at one end facing the positive direction of the X-axis, and the motor is a servo motor that can rotate in both directions. In addition, the belt rollers and belts on the profile arrangement conveyor 101 and the profile delivery and transmission platform 102 are also meshing transmissions, and the wrap angles are greater than 120°. The synchronous transmission between the profile delivery conveyor 102 and the profile arrangement conveyor 101 is similar, also through a long rotating shaft and two rollers and a meshing belt between the rollers.

[0045] The aluminum profiles are transferred from the profile delivery and transmission platform 102 to the profile arrangement and conveying platform 101 as follows: the ends of the aluminum profiles that have been cut in sections are aligned and stacked on the profile delivery and transmission platform 102, and there is a certain distance between each aluminum profile. The profile delivery and transmission platform 102 delivers the aluminum profiles one by one to the profile arrangement and conveying platform 101. There is a sensor above the profile delivery and transmission platform 102. After each aluminum profile is transported to the profile arrangement and conveying platform 101, the profile delivery and transmission platform 102 will stop conveying immediately. After the profile leaves the transmission plane of the belt on the profile delivery and transmission platform 102, it contacts the transmission plane of the belt on the profile arrangement and conveying platform 101, and the profile is transported to the stacking rack by the profile arrangement and conveying platform 101.

[0046] In order to arrange the spacing of the aluminum profiles conveyed onto the profile arrangement conveyor table 101, after the profiles are conveyed from the profile delivery transfer table 102 to the profile arrangement conveyor table 101, the profile arrangement conveyor table 101 needs to rotate a certain distance in the negative direction of the Y-axis to bring the newly conveyed profiles on the profile arrangement conveyor table 101 closer to the arranged profiles. At this time, a block needs to be set at one end of the profile arrangement conveyor table 101 close to the profile delivery transfer table 102. When rotating, it is ensured that the newly conveyed profiles on the profile arrangement conveyor table 101 will not move back to the profile delivery transfer table 102. In this embodiment, this function is achieved by the profile positioning electric rod 8. The profile positioning electric rod 8 is fixed on one side of each profile arrangement conveyor table 101 along the negative direction of the X-axis, and the profile positioning electric rod 8 is at the output end of the profile arrangement conveyor table 101. The output end of the profile positioning electric rod 8 can extend and retract in the Z-axis direction. When moving in the positive direction of the Z-axis, it extends, and when moving in the negative direction of the Z-axis, it retracts. When its telescopic rod is fully extended, the top is higher than the aluminum profiles on the profile arrangement conveyor table 101, and it can block and position the aluminum profiles to be arranged and conveyed. At this time, the profile arrangement conveyor table 101 rotates, and the arranged profiles can be moved towards the profile delivery transfer table 102. Conversely, the profiles are brought closer and stacked neatly. After the profiles are brought closer, the telescopic rod on the profile positioning electric rod 8 retracts downward. When the profile positioning electric rod 8 is fully retracted, the telescopic rod is lower than the surface of the profile arrangement conveyor table 101 and does not block the profiles, allowing the next profile to be conveyed onto the profile arrangement conveyor table 101.

[0047] In order to retrieve and stack the arranged profiles, several pads can be evenly arranged under the arranged profiles. After the pads move up synchronously, the arranged profiles are lifted as a whole. The pad conveyor table 201 provided on the base is used to convey the pads in the negative direction of the X-axis. As Figure 8 shown, the pad conveyor table 201 is under the profile arrangement conveyor table 101 and adopts the transmission form of a motor-driven belt to convey the pads placed on the pad conveyor table 201 backward at a fixed distance, so that the pads are placed in the gaps of the profile arrangement conveyor table 101. After the pads are in the gaps of the profile arrangement conveyor table 101, the pad clamp 6 lifts the arranged pads. After the pads rise and contact the lower ends of the arranged profiles, the pads continue to rise and lift the arranged profiles together.

[0048] For the delivery of the backing plates to the backing plate conveying table 201, the present invention further provides a backing plate delivery mechanism 4 on one side of the hoisting machine frame 3 along the positive X-axis direction. The backing plate delivery mechanism 4 includes: a backing plate delivery machine frame 401, a backing plate delivery transfer table 402, a delivery bracket 403, and a backing plate delivery clamp 404. The backing plate delivery machine frame 401 is aligned with the base in the middle of the hoisting machine frame 3. Slide rails are provided on both sides of the backing plate delivery machine frame 401 along the Y-axis direction. The backing plate delivery clamp 404 reciprocates along the X-axis direction on the slide rails through the hoisting slide seat at the top. In this application, a linear motor is used to control and drive the hoisting slide seat to achieve sliding. A lifting rod is installed at the bottom of the hoisting slide seat, and the output end of the lifting rod is fixedly connected to a backing plate delivery clamp 404. The backing plate delivery clamp 404 is used to clamp a whole layer of backing plates. The inner part of the backing plate delivery machine frame 401 near the positive X-axis end is used to stack the backing plates to be delivered layer by layer. An electromagnet can be provided at the bottom of the backing plate delivery clamp 404 to assist in adsorbing and clamping and lifting the arranged backing plate group. A backing plate delivery transfer table 402 aligned with the backing plate conveying table 201 is installed at the inner bottom of the backing plate delivery machine frame 401 near the hoisting machine frame 3. The backing plates can be delivered from the middle position of the backing plate delivery transfer table 402 to the backing plate conveying table 201. The backing plates are arranged at equal intervals in the middle of the backing plate conveying table 201 by mechanical conveying, which is convenient for arranging the profiles at intervals and stacking, dispersing the pressure on the bottom profiles, and reducing the plastic deformation of the bottom profiles caused by extrusion.

[0049] In order to transfer the backing plates from the backing plate delivery transfer table 402 to the backing plate conveying table 201, a delivery bracket 403 is installed at the bottom of the backing plate delivery machine frame 401 near the hoisting machine frame 3. The delivery bracket 403 consists of an electric push rod that can extend and retract along the X-axis direction and an electric push rod that can lift along the Z-axis. The electric push rod that can extend and retract along the X-axis direction is used as the horizontal telescopic rod, and the electric push rod that can lift along the Z-axis is used as the lifting rod. As Figure 6As shown in the figure, a transfer block is installed at the telescopic end of the horizontal telescopic rod. The side of the transfer block facing the positive direction of the Z-axis is used to install the lifting rod. The telescopic end at the top of the lifting rod is fixedly connected with a horizontal support plate for holding the backing plate. The delivery method of the backing plate is as follows: The backing plate delivery clamp 404 grabs and lifts the entire layer of backing plates stacked on the side of the backing plate delivery rack 401 away from the hoisting rack 3 and places them on the backing plate delivery transfer table 402, and is conveyed by the backing plate delivery transfer table 402 to one end in the negative X-axis direction. The delivery bracket 403 first lowers the support plate to a position below the backing plate on the backing plate delivery transfer table 402 through the lifting rod. The horizontal telescopic rod contracts, and the support plate is moved under the backing plate closest to the hoisting rack 3 in the negative X-axis direction. After aligning the backing plates, the lifting rod raises the support plate, and the support plate lifts the backing plate. After the backing plate leaves the backing plate delivery transfer table 402, the horizontal telescopic rod extends. The backing plate moves towards the backing plate conveying table 201. After the backing plate moves to the designated position on the backing plate conveying table 201, the telescopic rod contracts, and the support plate is lowered. The support plate passes through between the backing plate conveying tables 201, while the backing plate is blocked by the backing plate conveying table 201 and remains on it. The backing plate conveying table 201 moves a specified distance in the negative X-axis direction, and the backing plate delivery transfer table 402 also moves a distance of one backing plate in the negative X-axis direction to ensure that there is always a backing plate at the end closest to the hoisting rack 3, facilitating the arrangement of the next backing plate. This cycle continues until the number of backing plates arranged on the backing plate conveying table 201 reaches the number to be hoisted.

[0050] Inside the backing plate delivery rack 401, a backing plate partition is provided, which is used to separate the stacked backing plates from the backing plates to be delivered. The profile delivery transfer table 102 delivers the profiles arranged at intervals to the profile arrangement transfer table 101 one by one. After the aluminum profiles are delivered to the profile arrangement transfer table 101, the profile positioning electric rod 8 extends, and the profile arrangement transfer table 101 rotates. The single profile delivered to the profile arrangement transfer table 101 is squeezed and brought closer to the other profiles that have been arranged by using the profile positioning electric rod 8. Synchronously, the backing plates are delivered to the backing plate transfer table 201 one by one by the backing plate delivery mechanism 4. After the gaps between the backing plates and the profile arrangement transfer table 101 are aligned, and after the profiles on the profile arrangement transfer table 101 are arranged, the linear motor on the lifting and installation rack 3 drives the moving support to move in the X-axis direction for position adjustment. After the backing plate clamp 6 on the lifting and installation frame 501 determines that the two ends of the backing plate are aligned through the sensor, the two lifting telescopic rods on the moving support extend synchronously. The lifting and installation frame 501 is lowered. After the bottom of the gripping clamp 603 reaches below the backing plate, the two gripping clamps 603 close. After the bottom ends of the gripping clamps 603 coincide, they are lifted by the lifting telescopic rods. The evenly arranged backing plates are then lifted by the gripping clamps 603. The backing plates continue to rise and contact the bottom of the profiles. Subsequently, the arranged aluminum profiles are lifted by the backing plates. The moving support moves the lifting and installation frame 501 in the direction of the stacking rack 9. After the aluminum profiles on the gripped backing plates are aligned with the stacking rack 9, the lifting telescopic rods extend, and the lifting and installation frame 501 is lowered until the gripped profiles are lowered onto the profile stacking rack or onto the profiles stacked in the profile stacking rack.

[0051] When conveying non-circular profiles, the friction between the profiles and the conveyor belts on the profile arrangement transfer table 101 and the profile delivery transfer table 102 is mainly considered. When the profile arrangement transfer table 101 and the profile delivery transfer table 102 convey the profiles, it is necessary to prevent sliding friction between the profiles and the belts. The maximum static friction force between the belt and the profiles is approximately considered equal to the sliding friction force, which can be expressed as: 。

[0052] Among them, is the maximum static friction force between the profile and the belt; is the static friction coefficient between the profile and the belt; is the pressure of the profile on the surface of the belt, which is considered equal to the gravity of the profile here.

[0053] It is necessary to ensure the braking force when starting and stopping the drive belt: 。Among them, is the mass of the profile; It is the acceleration generated by the profile when the belt starts and stops. After the profile is transferred from the profile delivery and transfer table 102 to the profile arrangement and conveying table 101, the profile arrangement and conveying table 101 moves the arranged profiles and the newly delivered profiles together in the direction of the stacking rack 9. After the newly delivered profile moves beyond the profile positioning electric rod 8, the profile positioning electric rod 8 extends, and the PLC control system controls the profile arrangement and conveying table 101 to convey in the reverse direction. The newly delivered profile is blocked by the profile positioning electric rod 8, and relative displacement occurs between the belt and the profile on the profile arrangement and conveying table 101 until the newly delivered profile and the previously arranged profiles are close together.

[0054] There is a certain distance between the newly delivered aluminum profile and the previously arranged aluminum profile group. It is necessary to ensure that the reverse conveying distance of the profile arrangement and conveying table 101 is exactly equal to the distance between the profiles. After the profile arrangement work is completed, the backing plate is lifted and sent in the direction of the profile stacking rack. It is necessary to make the thickness of the chuck at the lower end of the grasping clamp 603 less than the height of the backing plate to ensure that the profiles above and below the backing plate will not hinder the opening and closing of the grasping clamp 603 when stacking the profiles.

[0055] Second Embodiment:

[0056] Based on the first embodiment, the present invention can also be used for aluminum profiles that may roll during transportation. When transporting this type of aluminum profile, not only the frictional transportation between the profile and the belt on the profile arrangement and conveying table 101 and the profile delivery and transfer table 102 needs to be considered, but also the rolling of the profile caused by the transmission differential between the profile and the belt needs to be considered. The belts on the profile arrangement and conveying table 101 and the profile delivery and transfer table 102 can be replaced with belts with a composite adhesive material on the outer surface. As Figure 11 shown, the upper layer is the adhesive material and the lower layer is the belt. The adhesive belt structure layers on the profile arrangement and conveying table 101 and the profile delivery and transfer table 102 can be composed of Figure 11 shown. The adhesive material layer attached to the surface of the belt on the profile arrangement and conveying table 101 and the profile delivery and transfer table 102 of the present invention can include: silicone-based pressure-sensitive adhesive, polyurethane elastomer adhesive, silicone-based adhesive. Taking the silicone-based pressure-sensitive adhesive as an example in the present invention, there can be a certain adhesion force between the bonding layer on the outer surface of the profile and the belt, and the silicone-based pressure-sensitive adhesive has a low surface energy and is an elastomer, which is beneficial to increasing the contact area between the profile and the belt, and the adhesive material is not easily transferred to the surface of the profile. The calculation of the adhesion force between the profile and the belt can be expressed as: .

[0057] Among them, is the adhesion force between the profile and the belt; is the static friction coefficient, which mainly depends on the characteristics of the adhesive material on the surface of the belt; is the pressure of the profile on the surface of the belt; is the contact unit area (taking 1 ); is the actual contact area. At the same time, when considering the adhesion between the profile and the belt, it is also necessary to consider the influence of acceleration on the rolling of the profile when starting and stopping the conveyor belt. Therefore, the adhesion force of the profile needs to satisfy the relationship: , where is the maximum adhesion force; is the static friction coefficient between the adhesive material on the belt and the profile; is the contact unit area; is the actual contact area; is the mass of the profile; is the acceleration caused to the profile when the conveyor belt starts and stops. To ensure the adhesion of the belt to the profile, it is necessary to replace or clean it regularly, and it is also necessary to ensure that when the surface adhesive material of the belt conveys the profile with paint on the surface, the separation of the profile and the belt will not cause the peeling of the paint on the profile surface. When this kind of profile is conveyed, the backing plate needs to play a supporting role for the profile. The metal plate at the center of the backing plate has magnetism and grooves can be opened on the upper and lower surfaces for the profile to be clamped and stacked, preventing the profile from rolling and ensuring the stability of the stack.

[0058] After the profile that will roll is conveyed to the profile arrangement and conveying table 101, the profile arrangement and conveying table 101 also needs to rotate to make the newly conveyed profile on the profile arrangement and conveying table 101 close to the arranged profile. The distance between the newly conveyed profile on the profile arrangement and conveying table 101 and the arranged profile needs to be the same as the distance that the profile rolling is blocked by the profile positioning electric rod 8, so as to set the rotation distance of the profile arrangement and conveying table 101.

[0059] When in use, the cut and segmented profiles are aligned at both ends and placed or conveyed to the profile delivery and conveying platform 102, and the profile delivery and conveying platform 102 conveys the profiles one by one to the profile arrangement and conveying platform 101. In order to prevent the sticky material on the belt surface from affecting the transfer of the profiles, the profile delivery and conveying platform 102 continuously conveys the profiles to the profile arrangement and conveying platform 101. After the profiles move to the point where the transfer strokes of the profile delivery and conveying platform 102 and the profile arrangement and conveying platform 101 overlap, the profile arrangement and conveying platform 101 and the profile delivery and conveying platform 102 continue to convey the profiles until the profiles are completely moved from the profile delivery and conveying platform 102 to the profile arrangement and conveying platform 101. At the same time, the mat delivery mechanism 4 on the mat delivery rack 401 clamps the arranged mats layer by layer through the mat delivery clamp 404 and delivers them to the mat delivery and transfer platform 402, and the mats delivered to the mat delivery and transfer platform 402 are delivered to the mat delivery platform 201 one by one in coordination with the extension and lifting of the transverse telescopic rod and the lifting rod. The mat delivery platform 201 delivers the mats one by one to the gaps of the profile arrangement and transfer platform 101, and aligns them with the grabbing clamp 603.

[0060] After the profiles are transported one by one to the profile arrangement and conveying platform 101, the profile arrangement and conveying platform 101 rotates to cooperate with the extension and retraction of the profile positioning electric rod 8 to position the profiles, so that the profiles are arranged neatly together. The arrangement of the profiles and the conveying and arrangement of the pads are carried out synchronously. Finally, the mobile support moves the lifting and mounting frame 501 along the Y-axis direction, and the lifting and retracting rod controls the lifting and lowering of the lifting and mounting frame 501. The grabbing clamp 603 clamps the two ends of the arranged pad and lifts it in the positive direction of the Z-axis. The pad continues to rise and lifts the arranged profiles. The grabbing clamp 603 is transported to the stacking rack 9. The side of the stacking rack 9 has a protective enclosure to protect the arranged profiles to prevent sliding or dislocation and ensure neat stacking. Repeat this process until the profiles are fully stacked on the stacking rack, and the profile stacking rack is replaced and the above steps are repeated.

[0061] In summary, the stacking device for aluminum profile processing of the present invention has the following advantages:

[0062] 1. The profile stacking device mainly includes: aluminum profile conveying assembly 1, pad conveying assembly 2, hoisting frame 3 and pad delivery mechanism 4, which are separated parts. The structure is simple and easy to repair and maintain. The profiles are continuously conveyed through the staggered distribution between the profile delivery and transmission platform 102 and the profile arrangement and delivery platform 101, and the start and stop coordination between the two. The spacing between the profiles is adjusted by the rotation of the profile arrangement and delivery platform 101 and the profile positioning electric rod 8.

[0063] Second, the profiles are placed in layers through the backing plates, making the profiles more convenient for storage and handling. Moreover, the clamping of the backing plates reduces the physical contact between the equipment clamping and the profiles directly, reducing the scratching and wear on the surface of the profiles. It is composed of separate components such as the hoisting rack 3, the aluminum profile conveying assembly 1, and the backing plate conveying assembly 2. The structure is simple, and the separation of each component facilitates maintenance and adjustment of the distribution according to different workshops.

[0064] Third, by replacing the conveyor belts on the profile delivery transfer table 102 and the profile arrangement conveyor table 101, belts with or without adhesiveness on the surface can be selected according to whether the profiles will roll during transportation and arrangement, ensuring the stability of profile transportation and arrangement, and increasing the ability of this palletizing device to convey and palletize different types of profiles. The conveying and arrangement of the backing plates are carried out synchronously with the conveying and arrangement of the profiles, with a higher degree of automation and labor savings.

[0065] The PLC control system for controlling motors, electric cylinders, and telescopic rods in the equipment, as well as the sensors for positioning, are all prior arts, which are common general knowledge in this field and do not belong to the improved technical points of this case, so they will not be elaborated here.
