Description

[0001] This application is a divisional application of a utility model patent with the patent number 2024217178621, the patent title of "A Strip-shaped Frame Clamping and Palletizing Device", and the application date of July 19, 2024.

Technical Field

[0002] The utility model belongs to the technical field of palletizing equipment, and particularly relates to a strip automatic feeding and placing mechanism and a palletizing device.

Background Art

[0003] Strip-shaped profiles are applied to many products, such as window frames, photovoltaic module frames, board edge frames, etc. After the strip-shaped profiles are cut, drilled, and chamfered, they need to be stacked into a three-dimensional stack structure and then tied into bundles with straps for subsequent handling and transportation. A palletizer is an automated device that can stack profiles according to a certain arrangement method to form a profile stack.

[0004] When stacking profiles, in some cases, an isolation paper strip needs to be laid at both ends and the middle position between each layer of profiles, and in some cases, a plastic steel belt also needs to be set between the set number of layers. For example, a plastic steel belt is placed between the 1st and 10th layers, and then a welding tool is held by hand to weld the joint of the plastic steel belt together to form a bundle. Then, a plastic steel belt is placed between the 8th and 15th layers, and the joint of the plastic steel belt is also welded together with the welding tool to form another bundle. There is an overlapping frame layer between the two palletized stacks. Therefore, forming the entire palletized stack into a whole can effectively prevent the stacked profiles from scattering and collapsing after palletizing.

[0005] In the prior art, patent CN116374533A discloses a strip-shaped profile palletizing device and a profile palletizing method, which realizes the automatic clamping and palletizing of the frames, but cannot realize the automatic placement of the isolation paper strip and the plastic steel belt. Therefore, it is necessary to provide a new strip automatic feeding and placing mechanism and a palletizing device to solve the above technical problems.

Detailed implementation manner

[0036] Example 1:

[0037] Please refer to Figures 1-9 This embodiment is a strip - shaped frame clamping and palletizing device 100, which includes a palletizing conveyor line 1, a palletizing station 10 located on the output side of the palletizing conveyor line 1, frame clamping mechanisms 2 arranged on both sides of the palletizing conveyor line 1, a palletizing handling mechanism 3 that transports a set number of cached frames on the palletizing conveyor line 1 as a whole to the palletizing station 10 for palletizing, and a strip feeding and placing unit 4 arranged at the palletizing station 10.

[0038] The palletizing conveyor line 1 includes a first conveyor line 11 and a second conveyor line 12 that are butt - jointed front and back. The frame clamping mechanisms 2 are arranged on the left and right sides of the first conveyor line 11, and the first conveyor line 11 is used to cooperate with the frame clamping mechanisms 2 to achieve frame clamping. A palletizing buffer station 20 is arranged on the second conveyor line 12 for caching the clamped frames to reach a set number.

[0039] A first conveyor line 11 is successively provided with a rectifying station and a frame buckling station along its conveying direction. A rectifying mechanism 5 for rectifying the positions of both ends of the frame is provided at the rectifying station, and a frame buckling mechanism 2 is provided corresponding to the frame buckling station. A first stop module 13 for blocking the frame from moving forward and a first sensor 14 for detecting the presence or absence of the frame are configured at both the rectifying station and the frame buckling station.

[0040] A blanking mechanism 15 for ensuring that only one frame is input to the frame buckling station each time is provided at the rectifying station or upstream of the input side. The blanking mechanism 15 ensures that the frame can be buckled without interference. It includes a second stop module 151 for blocking the frame on the first conveyor line 11 at the first frame position, a second sensor 152 for detecting whether there is a frame at the first frame position, a third sensor 153 for detecting whether there is a frame at the second frame position, a blanking plate 154 located above the second frame position or above the junction of the first frame position and the second frame position, and a first cylinder 155 for driving the blanking plate 154 to move downward when both the second sensor 152 and the third sensor 153 sense signals. The first frame position coincides with the rectifying station or is located upstream of the rectifying station, and the second frame position is adjacent to the first frame position and is located on the upstream side of the first frame position.

[0041] A blocking block 16 for blocking the foremost frame is provided at the output side of the palletizing buffer station 20, and a third stop module 17 is provided at the input side. A fourth sensor 18 for detecting whether there is a frame at the blocking block 16 and a fifth sensor 19 for detecting whether there is a frame at the third stop module 17 are provided on the palletizing buffer station 20. The blocking block 16 is used to block the first frame entering the palletizing buffer station 20. When the number of frames cached in the palletizing buffer station 20 reaches the set value, the third stop module 17 is used to block the subsequent frames to prevent the subsequent frames from entering the palletizing buffer station 20. When both the fourth sensor 18 and the fifth sensor 19 detect signals, it indicates that the palletizing buffer station 20 is full of the set number of frames.

[0042] After the frame is conveyed to the palletizing conveyor line 1, the blanking mechanism 15 controls the single frame to enter the rectifying station in sequence. The rectifying mechanism 5 rectifies it, and then it is moved to the frame buckling station. The frame buckling mechanism 2 clamps the frame and lifts it to a high position, and then flips it 180° and holds it. After the next frame reaches the frame buckling station, it is put down and buckled. The buckled frames are then conveyed to the palletizing buffer station 20. After the set number of buckled frames are cached on the palletizing buffer station 20, the palletizing handling mechanism 3 moves them away as a whole for palletizing.

[0043] The border clamping mechanism 2 includes two second sub-modules, which are respectively arranged on the left and right sides of the palletizing conveyor line 1. The second sub-module includes a first motor 21, a first support plate 22 driven by the first motor 21 to move up and down, a second motor 23 fixed on the first support plate 22, and a border clamping assembly 24 driven by the second motor 23 to rotate around a horizontal axis. The alignment mechanism 5 can be independently arranged at the alignment station, or can be arranged on the first support plate 22. In this embodiment, the alignment mechanism 5 is arranged on the first support plate 22. When the length specification of the border changes, the distance between the two second sub-modules can be adjusted. When adjusting the position of the second sub-module, the positions of the border clamping assembly 24 and the alignment mechanism 5 can be completed, which is convenient for adjustment to be applicable to various border lengths with different specifications.

[0044] The transfer range of the palletizing handling mechanism 3 covers the palletizing buffer station 20 and the palletizing station 10. The palletizing handling mechanism 3 includes an XZ transfer module 31, a lifting column 32 arranged at the movable end of the XZ transfer module 31, a bracket 33 fixed at the end of the lifting column 32, and hook modules 34 fixed at the opposite ends of the bracket 33 in the Y direction. By using the two groups of hook modules 34 to hold the two ends of a layer of borders, the picking up of the entire layer of borders is realized. The hook module 34 includes a sixth motor 341 fixed on the bracket 33, a second support plate 342 driven by the sixth motor 341 to move in the Y direction, a second cylinder 343 fixed on the second support plate 342, and a bottom support plate 344 driven by the second cylinder 343 to move in the Y direction. By driving the second support plate 342 to move by the sixth motor 341, it can be applicable to the handling of borders with various different length specifications. The hook module 34 further includes a vertical alignment surface 345 for aligning and rectifying the two ends of the border. The vertical alignment surface 345 is arranged on the bottom support plate 344 or the second support plate 342. When the palletizing handling mechanism 3 lifts the entire layer of borders, first, the two ends of the border are aligned and rectified by using the vertical alignment surface 345, and then the bottom support plate 344 is used to hold the bottoms of the two ends of the border to lift the entire layer of borders, ensuring the verticality during palletizing.

[0045] To prevent scratches from occurring due to friction between the borders of adjacent upper and lower layers during handling, during palletizing, it is required to place isolation paper strips at multiple positions between the borders of adjacent upper and lower layers. In this embodiment, it is required to place one isolation paper strip at each of the two ends and the middle of the border. Therefore, a total of three isolation paper strips need to be placed at three positions between the upper and lower layers of borders. Additionally, to ensure that the stacked borders are not easily loosened or toppled, during palletizing, it is required to tie a plastic-steel band between the bottommost border and the borders between the bottommost border and the first set layer (e.g., the 10th layer) to form a bundling unit, and then tie a plastic-steel band between the borders of the second set layer (e.g., the 8th layer) and the topmost border to form another bundling unit. Each bundling unit has plastic-steel bands at two positions. When tightening the plastic-steel bands, the joints of the plastic-steel bands can be welded together by manually holding a welding tool to complete the bundling; there are overlapping border layers between the first bundling unit and the second bundling unit, so that the entire stacked border pile forms a bundled whole and is not easily toppled or loosened.

[0046] To automatically place the above-mentioned isolation paper strips and plastic-steel bands, in this embodiment, a strip feeding and placing unit 4 is provided at the palletizing station 10. The strip feeding and placing unit 4 includes a strip feeding unit 41 and a strip pulling unit 42 located on opposite sides of the palletizing station 10.

[0047] The strip feeding unit 41 includes a third motor 411, a first support beam 412 driven by the third motor 411 to move up and down, a plurality of paper strip feeding modules 413 with adjustable positions provided on the first support beam 412, and a plurality of plastic-steel band feeding modules (not marked in the figure). The paper strip feeding modules 413 can be adjusted in advance to their positions on the first support beam 412 according to the placement positions of the isolation paper strips. The roll-shaped isolation paper strips are loaded on the paper strip feeding modules 413. Under the pulling force of the strip pulling unit 42, the end of the paper strip is pulled out, pulled from one side of the pallet to the opposite side of the pallet, then lowered and placed on each layer of the border, and then cut off by the scissors on the paper strip feeding modules 413 to complete the automatic placement of the isolation paper strips. The placement principle of the plastic-steel bands is the same as that of the isolation paper strips. The structures of the paper strip feeding modules 413 and the plastic-steel band feeding modules can adopt the existing tape feeding and cutting mechanism in the art, configured with a material roll placing support disk, a tape output port, and a tape cutting mechanism.

[0048] The strip holding unit 42 includes a fourth motor 421, a support column 422 driven by the fourth motor 421 to move parallel to the conveying direction of the palletizing conveyor line 1, a fifth motor 423 fixed on the support column 422, a second support beam 424 driven by the fifth motor 423 to move up and down, a plurality of paper strip end clamping assemblies 425 and a plurality of plastic steel strip end clamping assemblies 426 which are arranged on the second support beam 424 with adjustable positions; the paper strip end clamping assemblies 425 correspond to the positions of the paper strip feeding module 413, and the plastic steel strip end clamping assemblies 426 correspond to the positions of the plastic steel strip feeding module.

[0049] The working process of an automatic strip feeding and placing mechanism and a palletizing device 100 in this embodiment is as follows: the frame is conveyed into the device through the palletizing conveyor line 1, and the advancing frame is blocked by the material blocking mechanism 15, and it is controlled that only one frame enters the alignment station and the frame buckling station each time; after the frame reaches the alignment station, the positions of both ends of the frame are aligned by the alignment mechanism 5; then it reaches the frame buckling station, and the frame buckling mechanism 2 clamps both ends of the frame and lifts it up and then flips it 180° to the inverted state. When the next frame reaches the frame buckling station, the inverted frame is buckled to the frame below to form a buckled frame; the buckled frame is then conveyed to the palletizing buffer station 20 for temporary storage. When the set quantity is cached, the palletizing handling mechanism 3 transports the whole layer to the palletizing station 10 for palletizing. During the palletizing process, every time a layer is stacked, the paper strip end clamping assembly 425 in the strip holding unit 42 will move to the discharge end of the strip feeding unit 41, clamp the end of the isolation paper strip at the output end of the paper strip feeding module 413, then pull it out by a set length, then descend as a whole, place it on the surface of the topmost frame currently, and then cut it off by the cutting module to complete the automatic placement of the isolation paper strip; similarly, when it is necessary to place the plastic steel strip, the plastic steel strip end clamping assembly 426 in the strip holding unit 42 moves to the discharge end of the strip feeding unit 41, clamps the end of the plastic steel strip at the output end of the plastic steel strip feeding module, then pulls it out by a set length, then descend as a whole, place it on the surface of the topmost frame currently, and then cut it off by the cutting module to complete the automatic placement of the plastic steel strip. An artificially cut isolation paper strip is placed on one side where the plastic steel strip contacts the frame. When the set number of layers of frames are placed on the plastic steel strip, the operator welds the ends of the plastic steel strip together to form a bundling unit.

[0050] For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
