Description

Technical Field

[0001] This utility model relates to the field of profile stacking technology, and in particular to an automatic profile stacking machine. Background Technology

[0002] Profiles are products with specific shapes made of malleable metals or non-metals, widely used in photovoltaic frames, building door and window frames, and railings. The process of transforming profiles from raw parts into finished products typically involves cutting, milling, drilling, and installing corner brackets, followed by stacking and transportation to the assembly station for final assembly. Because some profiles have grooves and protrusions on one side, forming an "L" shape, to improve space utilization and stacking stability, the grooved and protruding sides of the upper and lower profiles are first aligned and overlapped, and then the overlapped profiles are stacked layer by layer on a pallet. Furthermore, in some cases, corner brackets need to be inserted at both ends of the profiles. To ensure a more secure and stable fit when overlapping, the ends of the two overlapping layers of profiles need to be misaligned (i.e., the ends of the upper and lower layers are not aligned), so that the corner brackets on the two layers are staggered.

[0003] Currently available profile palletizing equipment can only handle profiles with regular shapes and outlines, and is not suitable for palletizing the aforementioned profiles. Therefore, the stacking of these profiles can only be done manually or by manually covering them and then using existing palletizing equipment to transfer the covered profiles to pallets. These manual stacking methods, or those combining manual and equipment stacking, suffer from low efficiency and high labor intensity, and cannot meet the demands of current large-scale automated production.

[0004] The technical problem to be solved by this utility model is: how to solve the problems of low work efficiency and high labor intensity of existing profile palletizing operations. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic profile stacking machine, which can replace manual labor for automatic stacking of profiles and has the characteristics of high work efficiency.

[0006] The technical solution adopted by this utility model is as follows: an automatic profile stacking machine, including a frame, the frame including a support frame and a truss disposed at one end of the support frame, and also including a feeding mechanism, a flipping and covering mechanism and a stacking mechanism installed on the support frame.

[0007] The feeding mechanism includes a cover conveyor belt and a discharge conveyor belt arranged sequentially on the support frame, with the discharge conveyor belt close to the truss;

[0008] The flipping and closing mechanism includes a flipping component and a misalignment component. The flipping component includes clamping arms disposed on opposite sides of the closing conveyor belt, a clamping power component that drives the two clamping arms to move closer or further apart, and a flipping power component that drives the two clamping arms to flip. The misalignment component includes misalignment plates disposed on opposite sides of the closing conveyor belt and a misalignment power component that drives the two misalignment plates to move closer or further apart.

[0009] The palletizing mechanism includes a palletizing gripper that is slidably connected to the truss, a palletizing translational force component that drives the palletizing gripper to move horizontally back and forth, and a palletizing lifting power component that drives the palletizing gripper to move vertically up and down. The palletizing gripper includes two oppositely arranged pallets and a material gripping power component that drives the two pallets to move closer or further apart.

[0010] The automatic profile stacker of this application can replace manual operations for flipping, covering, and stacking profiles, and features high work efficiency and a high degree of automation. The flipping component clamps the upper profile on the covering conveyor belt and flips it 180°. At the same time, the misalignment power component drives two misalignment plates to misalign the lower profile on the covering conveyor belt with the ends of the upper profile. Then, the clamping arm releases the upper profile, so that the upper and lower profiles cover each other. The two covered profiles are then conveyed to the discharge conveyor belt, where a stacking gripper lifts the two covered profiles and transfers them to a pallet for stacking.

[0011] In some embodiments, the palletizing gripper also includes a gripper frame slidably connected to the support frame, a gripping power component is mounted on the gripper frame, two gripper slides are slidably provided at both ends of the gripper frame, the gripper slides are drivenly connected to the gripping power component, and the pallet is connected to the gripper slides.

[0012] Using the above technical solution, the material gripping power component drives the two gripper slides to move closer or further apart, thereby causing the two pallets to move closer or further apart, thus realizing the gripping or lowering of the closed profile.

[0013] In some embodiments, the palletizing gripper also includes a pressure plate and a pressure power component mounted on the gripper slide. The pressure plate is positioned above the pallet and inside the pallet, and the pressure power component is used to drive the pressure plate to move up and down.

[0014] By adopting the above technical solution, a pressure plate is set above the pallet. When the palletizing gripper holds the profile, the pressure power component drives the pressure plate to descend and press the profile onto the pallet, preventing the profile from shaking and making the gripping of the profile more reliable. When it is necessary to put the profile down, the pressure power component first drives the pressure plate to rise, and then the gripping power component drives the two pallets to open outward, so that the profile is placed on the pallet.

[0015] In some embodiments, the palletizing gripper also includes an anti-reverse baffle and a pull-out power component mounted on the gripper slide. The anti-reverse baffle is located on the side of the pressure plate near the pallet and above the pallet. The pull-out power component is used to drive the pallet to extend or retract from the bottom of the anti-reverse baffle.

[0016] Using the above technical solution, when the profile is placed down, the anti-reverse baffle remains stationary during pallet retraction. The pallet pull-out power component drives the pallet to be pulled back from the bottom of the anti-reverse baffle. The anti-reverse baffle can prevent the profile from moving along with the pallet, ensuring that the profiles stacked on the pallet remain neat.

[0017] In some embodiments, the flipping assembly further includes flipping frames disposed on opposite sides of the cover conveyor belt, the flipping frames being slidably connected to the support frame, the clamping power component being drively connected to the flipping frames on both sides for driving the flipping frames on both sides to move closer or further apart, a flipping lifting platform being slidably disposed on the flipping frame, the clamping arm being rotatably connected to the flipping lifting platform, the flipping power component being mounted on the flipping lifting platform, and a flipping lifting power component being mounted on the flipping frame for driving the flipping lifting platform to move up and down.

[0018] With the above technical solution, the flipping frame and the support frame are slidably connected. The distance between the two flipping frames can be adjusted according to the length of the profile so that the distance matches the length of the profile. The clamping power component drives the two flipping frames to slide, so that the clamping power component can be used as both the power component for adjusting the distance and the power component for clamping the profile. By installing the clamping arm on the flipping lifting platform, the profile can be raised first during flipping, then flipped 180° and then lowered to cover the lower profile. This can prevent interference with the support frame and the cover conveyor belt during the flipping process.

[0019] In some embodiments, the flipping and closing mechanism further includes two sets of first isolator placement assemblies respectively disposed on opposite sides of the closing conveyor belt;

[0020] The single-unit first isolation component placement assembly includes a first unwinding component, a first cutting component, a first stretching component, and a first placement component. The first unwinding component is installed on a tilting frame, the first cutting component is installed at one end of the tilting frame, the first stretching component is arranged opposite to the first cutting component, the first stretching component is slidably connected to the tilting frame, the tilting frame is provided with a first stretching power component that drives the first stretching component to slide back and forth, the first placement component is slidably connected to the tilting frame, the tilting frame is provided with a feeding power component that drives the first placement component to approach or move away from the cover conveyor belt, and the first placement component is provided with at least one first clamp.

[0021] Using the above technical solution, the first isolation component placement assembly is used to prevent isolation between the corner brackets of the upper and lower cover profiles, so as to separate the corner brackets of the two profiles and avoid scratches between the corner brackets affecting the surface quality.

[0022] In some embodiments, the feeding mechanism also includes an infeed conveyor belt located at the end of the cover conveyor belt away from the discharge conveyor belt, with alignment plates arranged on opposite sides of the infeed conveyor belt, and an alignment power component installed on the frame to drive the alignment plates on both sides to move closer or further apart.

[0023] Using the above technical solution, the feeding conveyor belt is used to transport the profiles to the closing conveyor belt. The alignment plate and the alignment power component work together to align the profiles on the feeding conveyor belt, so that the two ends of the profiles are aligned, which facilitates the subsequent clamping, flipping and closing operations.

[0024] In some embodiments, the flipping and closing mechanism further includes a lifting assembly, which includes lifting members disposed on opposite sides of the closing conveyor belt and a lifting power member for driving the lifting members to rise and fall.

[0025] Using the above technical solution, the top material assembly is used to lift the profile on the cover conveyor belt so that the clamping arm can pick up the profile to be flipped.

[0026] In some embodiments, the palletizing mechanism further includes two sets of second spacer placement assemblies disposed on opposite sides of the palletizing gripper;

[0027] The single-unit second isolation component placement assembly includes a second unwinding component, a second cutting component, a stretching frame, and a second clamp. The second unwinding component is installed on the support frame, the second cutting component is installed on one end of the support frame near the truss, the stretching frame is slidably connected to the truss, a second stretching power component for driving the stretching frame to reciprocate is installed on the truss, and the second clamp is installed on the stretching frame.

[0028] Using the above technical solution, the second separator is used to place a separator between two stacked profiles to prevent the two stacked profiles from directly contacting each other, so as to avoid the profiles colliding with each other and affecting the surface quality.

[0029] In some embodiments, the single set of second isolation member placement assembly further includes a lifting placement power member, the second clamp being slidably connected to the tension frame, and the lifting placement power member being mounted on the tension frame to drive the second clamp to move up and down in the vertical direction.

[0030] By adopting the above technical solution, the lifting and placing power component drives the second clamp to lift and lower, so that the height of the second clamp matches the height of the profile stack, thereby improving the accuracy of the placement of the separator.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] Please see Figures 1 to 9 An automatic profile stacking machine 100, a preferred embodiment of the present invention, includes a frame 10, a feeding mechanism 20 mounted on the frame 10, a flipping and covering mechanism, and a stacking mechanism 70. The feeding mechanism 20 is used to transport profiles. The flipping and covering mechanism is used to flip the upper profile of two layers of profiles to be covered by 180° before covering the lower profile. The stacking mechanism 70 is used to transfer the covered profiles from the feeding mechanism 20 to a pallet and stack them neatly. The automatic profile stacking machine 100 of this application can automatically stack profiles instead of manually, and has the characteristics of high efficiency and high degree of automation.

[0045] like Figure 1 As shown, the frame 10 includes a support frame 11 and a truss 12 disposed at one end of the support frame 11. The feeding mechanism 20 and the flipping and covering mechanism are mounted on the support frame 11, and the stacking mechanism 70 is mounted on the truss 12.

[0046] like Figure 3As shown, the feeding mechanism 20 includes a feeding conveyor belt 21, a covering conveyor belt 22, and a discharging conveyor belt 23 arranged sequentially on the support frame 11. The discharging conveyor belt 23 is close to the truss 12. The feeding conveyor belt 21 is used to convey profiles to the covering conveyor belt 22. The two layers of profiles to be flipped and covered are flipped and covered on the covering conveyor belt 22. The discharging conveyor belt 23 is used to convey the covered profiles away so that the stacking mechanism 70 can stack them.

[0047] Furthermore, alignment plates 24 are provided on opposite sides of the feeding conveyor belt 21, and an alignment power component 25 is also installed on the frame 10 to drive the alignment plates 24 to move closer or further apart. The feeding conveyor belt 21 is used to transport profiles onto the closing conveyor belt 22. The alignment plates 24 and the alignment power component 25 cooperate to align the profiles on the feeding conveyor belt 21, ensuring that the two ends of the profiles are aligned, facilitating subsequent clamping, flipping, and closing operations. Optionally, the alignment power component 25 is a cylinder.

[0048] like Figures 2 to 6 As shown, the flipping and closing mechanism includes a flipping component 30 and a misalignment component 40. The flipping component 30 includes clamping arms 31 disposed on opposite sides of the closing conveyor belt 22, a clamping power member 32 that drives the two clamping arms 31 to move closer or further apart, and a flipping power member 33 that drives the two clamping arms 31 to flip. The misalignment component 40 includes misalignment plates 41 disposed on opposite sides of the closing conveyor belt 22 and a misalignment power member 42 that drives the two misalignment plates 41 to move closer or further apart. The flipping component 30 clamps and flips the upper profile on the closing conveyor belt 22 by 180°, while the misalignment power member 42 drives the two misalignment plates 41 to misalign the ends of the lower profile on the closing conveyor belt 22 with those of the upper profile. Then, the clamping arms 31 release the upper profile, causing the upper and lower profiles to close together.

[0049] Furthermore, the flipping assembly 30 also includes flipping frames 34 disposed on opposite sides of the cover conveyor belt 22. The flipping frames 34 are slidably connected to the support frame 11. The clamping power component 32 is mounted on the support frame 11 and is drivenly connected to the flipping frames 34 on both sides, for driving the flipping frames 34 on both sides to move closer or further apart. A flipping lifting platform 35 is slidably disposed on the flipping frame 34. The clamping arm 31 is rotatably connected to the flipping lifting platform 35. The flipping power component 33 is mounted on the flipping lifting platform 35. A material turning lifting power component 36 for driving the flipping lifting platform 35 to rise and fall is installed on the flipping frame 34. The flipping frame 34 is slidably connected to the support frame 11. The distance between the two flipping frames 34 can be adjusted according to the length of the profile so that the distance matches the length of the profile. The clamping power component 32 drives the two flipping frames 34 to slide, so that the clamping power component 32 can be used as both a power component for adjusting the distance and a power component for clamping the profile. By installing the clamping arm 31 on the flipping lifting platform 35, the profile can be raised first during flipping, then flipped 180° and then lowered to cover the lower profile. This can prevent interference with the support frame 11 and the covering conveyor belt 22 during the flipping process.

[0050] In this embodiment, the clamping power component 32, the tilting power component 33, and the material tilting and lifting power component 36 are all motors. A servo motor is preferred.

[0051] To prevent the corner brackets between the two overlapping profiles from colliding, the flipping and closing mechanism also includes two sets of first isolation component placement assemblies 50 respectively arranged on opposite sides of the closing conveyor belt 22.

[0052] like Figure 5 and Figure 6 As shown, specifically, the single-unit first separator placement assembly 50 includes a first unwinding member 51, a first cutting member 52, a first stretching member 53, and a first placement member 54. The first unwinding member 51 is mounted on the flipping frame 34, the first cutting member 52 is mounted on one end of the flipping frame 34, the first stretching member 53 is disposed opposite to the first cutting member 52, and the first stretching member 53 is slidably connected to the flipping frame 34. The flipping frame 34 is provided with a first stretching power member 55 that drives the first stretching member 53 to reciprocate. The first placement member 54 is slidably connected to the flipping frame 34, and the flipping frame 34 is provided with a feeding power member that drives the first placement member 54 to approach or move away from the covering conveyor belt 22. The first placement member 54 is provided with at least one first clamp 541. The first separator placement assembly 50 is used to prevent separators between the corner brackets of the upper and lower layers of profiles being covered, so as to separate the corner brackets of the two layers of profiles and avoid scratches between the corner brackets affecting the surface quality.

[0053] The working principle of the first isolator placement assembly 50: The first isolator rolled up is sleeved on the first unwinding member 51. The first isolator is conveyed to the first cutting member 52. Then, the first stretching member 53 is driven by the first stretching power member 55 to move and pull the first isolator to the required length. Then, the first clamp 541 on the first placement member 54 clamps the first isolator. Subsequently, the first cutting member 52 cuts the first isolator. Then, the feeding power member drives the first placement member 54 to move toward the closing conveyor belt 22. Before the two profiles are closed, the first isolator is sent to the corner code surface of the lower profile. Then, the feeding power member drives the first placement member 54 to reset. Then, the clamping arm 31 closes the upper profile onto the lower profile. The first isolator is pressed between the corner codes of the two profiles, separating the corner codes.

[0054] In this embodiment, the first clamp 541 is a pneumatic clamp, and a pneumatic clamp is also provided on the first stretching member 53. The feeding power member is a cylinder, the first stretching power member 55 is a motor, and the first cutting member 52 is a pneumatic scissor.

[0055] Preferably, in order to match the spacing of the misaligned plates 41 on both sides, the spacing of the two sets of first isolation component placement assemblies 50, and the spacing of the aligning plates 24 on both sides with the length of the profile, the misaligned assembly 40, the aligning plate 24, the aligning power component 25, and the first isolation component placement assembly 50 are all mounted on the flipping frame 34.

[0056] In one embodiment, the flipping and closing mechanism further includes a lifting assembly 60. The lifting assembly includes lifting members 61 disposed on opposite sides of the closing conveyor belt 22 and a lifting power member 62 for driving the lifting members 61 to rise and fall. The lifting assembly 60 is used to lift the profiles on the closing conveyor belt 22 so that the clamping arm 31 can clamp the profiles to be flipped. In this embodiment, the lifting power member 62 is a cylinder.

[0057] Please see Figure 2 and Figure 7 The palletizing mechanism 70 includes a palletizing gripper 71 slidably connected to the truss 12, a palletizing translational force component 72 that drives the palletizing gripper 71 to move horizontally back and forth, and a palletizing lifting force component 73 that drives the palletizing gripper 71 to move vertically up and down. The palletizing gripper 71 includes two oppositely arranged pallets 711 and a material gripping force component 712 that drives the two pallets 711 to move closer or further away from each other.

[0058] Specifically, the palletizing gripper 71 also includes a gripper frame 713 slidably connected to the support frame 11. A gripping power unit 712 is mounted on the gripper frame 713. Two gripper slides 714 are slidably arranged at both ends of the gripper frame 713. The gripper slides 714 are drively connected to the gripping power unit 712, and the pallet 711 is connected to the gripper slides 714. The gripping power unit 712 drives the two gripper slides 714 to move closer or further apart, thereby causing the two pallets 711 to move closer or further apart, realizing the gripping or lowering of the closed profile. In this embodiment, the gripping power unit is a motor.

[0059] Furthermore, a slide is provided on the truss 12, and the slide is slidably connected to the truss 12. The slide is driven by the stacking translational force component 72 to perform horizontal reciprocating motion. The gripper frame 713 is slidably connected to the slide, and the gripper frame 713 is driven by the stacking lifting power component 73 to perform vertical reciprocating motion.

[0060] Optionally, the palletizing horizontal movement component 72, the palletizing lifting power component 73, and the material gripping power component 712 are all servo motors.

[0061] Furthermore, the palletizing gripper 71 also includes a pressure plate 715 and a pressure power component 716 mounted on the gripper slide 714. The pressure plate 715 is positioned above the pallet 711 and is located inside the pallet 711. The pressure power component 716 is used to drive the pressure plate 715 to rise and fall. By setting the pressure plate 715 above the pallet 711, when the palletizing gripper 71 clamps the profile, the pressure power component drives the pressure plate 715 to descend and press the profile onto the pallet 711, preventing the profile from shaking and making the gripping of the profile more reliable. When it is necessary to lower the profile, the pressure power component 716 first drives the pressure plate 715 to rise, and then the gripping power component 712 drives the two pallets 711 to open outward, so that the profile is placed on the pallet.

[0062] Furthermore, such as Figure 9 As shown, the palletizing gripper 71 also includes an anti-reverse baffle 717 and a pull-out power component 718 mounted on the gripper slide 714. The anti-reverse baffle 717 is located on the side of the pressure plate 715 near the pallet 711 and is positioned above the pallet 711. The pull-out power component 718 is used to drive the pallet 711 to extend or retract from the bottom of the anti-reverse baffle 717. When the profile is being lowered, the anti-reverse baffle 717 remains stationary while the pallet 711 is retracted. The pull-out power component 718 drives the pallet 711 to retract from the bottom of the anti-reverse baffle 717. The anti-reverse baffle 717 prevents the profile from moving as the pallet 711 is pulled out, ensuring that the profiles stacked on the pallet remain neat.

[0063] In this embodiment, both the pressing power component 716 and the drawing plate power component 718 are cylinders.

[0064] To prevent the two stacked profiles from contacting each other directly, a second spacer is placed between the two stacked profiles to separate them (here, the stacked profile refers to the two profiles that have already been covered). The stacking mechanism 70 also includes two sets of second spacer placement components 74 arranged on opposite sides of the stacking gripper 71. The second spacer placement components 74 are used to place a second spacer between the two stacked profiles.

[0065] like Figure 7 and Figure 8 As shown, specifically, the single-unit second spacer placement assembly 74 includes a second unwinding component 741, a second cutting component 742, a stretching frame 743, and a second clamp 744. The second unwinding component 741 is mounted on the support frame 11, the second cutting component 742 is mounted on one end of the support frame 11 near the truss 12, the stretching frame 743 is slidably connected to the truss 12, and a second stretching power component 745 for driving the stretching frame 743 to reciprocate is mounted on the truss 12. The second clamp 744 is mounted on the stretching frame 743. The second spacer is used to place a spacer between two stacked profiles to prevent the two stacked profiles from directly contacting each other, thereby avoiding collisions between the profiles and affecting the surface quality.

[0066] Furthermore, the single-unit second spacer placement assembly 74 also includes a lifting and placing power component 746. The second clamp 744 is slidably connected to the tension frame 743, and the lifting and placing power component 746 is mounted on the tension frame 743 to drive the second clamp 744 to move up and down in the vertical direction. The lifting and placing power component 746 drives the second clamp 744 to move up and down, so that the height of the second clamp 744 matches the height of the profile stack, improving the accuracy of spacer placement.

[0067] In this embodiment, the lifting and placing power component 746 and the second stretching power component 745 are both servo motors, the second clamp 744 is a pneumatic clamp, and the second cutting component 742 is a pneumatic scissor.

[0068] Preferably, to match the spacing between the two sets of second spacer placement assemblies 74 with the length of the profile, a spacing adjustment assembly is also provided for adjusting the spacing between the two sets of second spacer placement assemblies 74. The spacing adjustment assembly includes a lead screw threadedly connected to the second cutting member 742 and the second unwinding member 741 in the two sets of second spacer placement assemblies 74. A handwheel is provided at one end of the lead screw, and the distance between the second cutting member 742 and the second unwinding member 741 on both sides can be changed by turning the handwheel. A motor is provided on the tension frame 743 for adjusting the spacing between the two second clamps 744, and the spacing between the two second clamps 744 is adjusted by driving the motor.

[0069] The working principle of the second spacer placement assembly 74 is similar to that of the first spacer placement assembly 50: the rolled second spacer is placed on the second unwinding member 741, the second clamp 744 clamps the second spacer, the lifting placement power member 746 drives the second clamp 744 to rise to a height matching the stacking height, then the stretching power member drives the stretching frame 743 and the second clamp 744 to move horizontally to stretch the second spacer to the required length, and then the second cutting member 742 cuts the second spacer so that the second spacer falls on the profile surface. When the upper layer of profile is stacked on it, the second spacer will separate the two layers of profile to prevent the two layers of profile from contacting each other directly, so as to protect the profile.

[0070] Optionally, the first and second spacers can be flexible roll materials such as cloth, plastic, paper, or leather.

[0071] During stacking, the feeding conveyor belt 21 conveys the profiles to the covering conveyor belt 22. The top material assembly 60 lifts the profiles to be flipped on the covering conveyor belt 22. The clamping arm 31 then clamps the lifted profiles, raises them to a specified height, and flips them 180°. At the same time, the first isolation component placement assembly 50 places the first isolation component at the corner of the profile on the covering conveyor belt 22. The clamping arm 31 covers the flipped profiles on the profiles on the covering conveyor belt 22, completing the covering operation of two layers of profiles. Then, the covered profiles are conveyed to the discharge conveyor belt 23. The stacking gripper 71 picks up the profiles from the discharge conveyor belt 23, lifts them, and moves them horizontally above the pallet. At the same time, the second isolation component placement assembly 74 places the second isolation component on the surface of the pallet or the surface of the topmost profile on the pallet. The stacking gripper 71 then places the profiles on the surface of the second isolation component. The above operations are repeated to perform automatic continuous stacking of profiles.
