[0002] Angle steel, commonly known as angle iron, is a long steel strip with two sides perpendicular to each other. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connectors between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.

The openings of the two adjacent layers of angle steels are set in opposite directions and the angle steels of the upper layer are arranged on both sides of the two angle steels of the lower layer. This occupies a small space. After being stacked up and down, they can play the role of layer-by-layer stacking and pressing. They have good stability and are not easy to tilt or misalign.

[0051] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0052] like Figure 1 As shown, the angle steel stacker includes a loading component 10, a flipping and stacking component 50, a receiving component 60 and a transfer alignment component 30 which are arranged in sequence in an assembly line. The loading component 10 is used for conveying and guiding the angle steels, and can be a conveyor chain structure, which can be realized by directly adopting a structure purchased on the market. Steel plates for guidance are arranged on both sides of the conveying direction, and can also be a conveyor belt or other steel roller conveying structure, which can realize automatic loading of the angle steels and can realize the loading of the present application. The flipping and stacking component 50 is used for clamping and flipping the angle steels, and after flipping and unloading, it is placed on the receiving component 60 to realize multi-layer stacking. The transfer alignment component 30 is used for the transportation of the angle steels from the receiving component to the unloading position and the end alignment of the angle steels.

[0053] like Figure 2-Figure 8 As shown, the flip stacking assembly 50 includes a left disk assembly 51 and a right disk assembly 52 that are symmetrically arranged. The left disk assembly 51 and the right disk assembly 52 have the same structure and rotate synchronously.

[0054] The left disc assembly 51 includes a fixed bracket 511, a large turntable 512 and a clamping assembly 513. The large turntable 512 is vertically arranged and rotatably connected to the fixed bracket 511. There are multiple clamping assemblies 513. When the clamping assemblies 513 are in a horizontal state, the upper and lower surfaces of adjacent clamping assemblies 513 are relatively arranged. The opening and closing of the clamping assemblies 513 corresponds to the unloading and loading clamping of the angle steel 53. A control assembly 514 for controlling the opening and closing of the clamping assembly 513 is provided on the fixed bracket 511.

[0055] Preferably, an intermediate shaft 54 ​​is provided between the left disc assembly 51 and the right disc assembly 52 . The intermediate shaft 54 ​​is driven to rotate by a driving motor 55 . Both ends of the intermediate shaft 54 ​​are fixed to the fixing bracket 511 to realize synchronous rotation.

[0056] Preferably, there are four clamping assemblies 513 and they are evenly distributed relative to the axis of the large turntable 512. Driving gears are provided at both ends of the intermediate shaft 54. The driving gear is coaxially arranged with the large turntable 512. Driven gears are provided on two non-adjacent clamping assemblies 513. The driving gear is meshed with the driven gear. The pitch circle radius of the driving gear and the driven gear is the same, ensuring that when the large turntable 512 rotates 180 degrees, the driven gear also rotates 180 degrees, thereby realizing translation from loading to unloading, translation, flipping, translation, flipping, and reciprocating stacking.

[0057] Preferably, there are two control components 514, one of which is arranged at the horizontal loading position, and the other is arranged at the horizontal unloading position. The control component 514 includes a push-pull cylinder 5141 and a push-pull block 5142. The push-pull block 5142 is arranged on the output shaft of the push-pull cylinder 5141. The push-pull block 5142 is a concave structure. Corresponding to the push-pull block 5142 is a rotating roller 5143. The rotating roller 5143 moves forward and backward with the push-pull block 5142 under the action of the push-pull cylinder 5141. The rotating roller 5143 structure can reduce the friction coefficient and realize the opening and closing action of the clamping component 513. The structure of the push-pull cylinder 5141 and the push-pull block 5142 is simple in structure, stable and reliable, convenient for maintenance and replacement, and low in cost.

[0058] Preferably, the clamping assembly 513 also includes a slide groove 5131, a rotating shaft 5132, an upper clamping jaw 5133, a lower clamping jaw 5134 and a movable frame 5135.

One end of the rotating shaft 5132 is connected to the movable frame 5135, and the other end is fixedly connected to the rotating roller 5143. The upper clamping jaw 5133 and the lower clamping jaw 5134 are correspondingly arranged up and down, and the opposite surfaces are provided with positioning grooves 5136 for clamping the angle steel 53. There are multiple positioning grooves 5136, and multiple positioning grooves 5136 are arranged in parallel, which can simultaneously realize the clamping and positioning of multiple angle steels 53, thereby improving work efficiency. The upper clamping jaw 5133 and the lower clamping jaw 5134 are both hinged on the movable frame 5135 at one end, and the other end is provided with a guide groove 5137. The guide groove 5137 is arranged obliquely downward from one end close to the rotating shaft 5132 to the other end, and a guide support rod 5138 is arranged on the slide groove 5131 corresponding to the guide groove 5137. When the upper clamping jaw 5133 and the lower clamping jaw 5134 move forward and backward with the movable frame 5135, the guide support is arranged in the guide groove 5137. Due to the arrangement of the guide support rod 5138, during the process of the upper clamping jaw 5133 and the lower clamping jaw 5134 moving backward, they will gradually open to a certain angle, at this time, the unloading action of the angle steel 53 is realized, and during the process of the movable frame 5135 being pushed forward, the upper clamping jaw 5133 and the lower clamping jaw 5134 approach each other and clamp the angle steel 53, realizing the initial loading clamping, and after clamping, they rotate together with the large turntable 512 to realize flipping.

[0059] Preferably, the push-pull block 5142 is arranged on the slider 5144 of the linear rail structure, and the guide rail 5145 of the linear rail structure is fixed on the fixed bracket 511.

In the initial feeding state, the clamping assembly 513 is opened, the upper clamping jaw 5133 and the lower clamping jaw 5134 are opened to a certain angle, and then the two ends of the angle steel 53 are clamped at the same time. After clamping, the large turntable 512 rotates. After the large turntable 512 rotates 180 degrees, the angle steel 53 returns to the horizontal state on the other side. At this time, the clamping assembly 513 is opened, the upper clamping jaw 5133 and the lower clamping jaw 5134 are separated, and the angle steel 53 It falls onto the corresponding lifting platform, and the number of clamping components 513 is set to four, that is, one is set at 90 degrees. In the two adjacent clamping components 513, one is set with a driven gear, and the other is not set with a driven gear. In the clamping component 513 with a driven gear, the driven gear and the driving gear are meshed and set. While rotating 180 degrees with the large turntable 512, it rotates 180 degrees itself, so that the angle steel 53 does not rotate. That is, the current angle steel 53 is laid flat, and the next angle steel 53 is rotated 180 degrees and placed, and then the cycle is repeated in sequence, so that multi-layer front and back stacking and stacking are realized.

The transverse linkage rod 671 moves downward under the action of the clamping cylinder 67, and drives the clamping rod 673 to flip upward around the rotating shaft 675 to a vertical state through the crescent link 672, thereby completing the side positioning of the diagonal steel stack and improving safety.

[0066] Preferably, when the output shaft of the clamping cylinder is retracted, the clamping rod 673 is in a vertical state, and the distance between the two clamps is greater than or equal to the width of the angle steel stack, so the side of the angle steel is guided and positioned to improve stability; more preferably, guide shafts are symmetrically provided on both sides of the output shaft of the clamping cylinder, and the guide shafts are arranged parallel to the output shaft. After the guide shafts are arranged, the movement stability of the clamping cylinder is improved, and the lifting accuracy is guaranteed, that is, the movement accuracy of the clamping rod 673 is guaranteed.

[0069] In actual use, when stacking angle steels, they need to be stacked in multiple layers. At the beginning of the stacking process, the lifting platform 65 rises to the best position under the action of the lifting screw 64 to ensure that the angle steel has as little height difference as possible with the upper end surface of the lifting platform 65 during the unloading process.

For each layer of the angle steel stacked, the lifting platform 65 descends a certain corresponding distance, thereby realizing stable stacking of multiple layers. , avoiding the stacking impact under the height difference, better stability, reduced noise, and no bumps on the angle steel, which is beneficial to ensuring the quality of the angle steel. After stacking to a preset height, the clamping cylinder 67 is actuated, the output shaft of the clamping cylinder 67 is retracted, and the transverse linkage rod 671 descends, driving the upper end of the crescent connecting rod 672 to descend, thereby driving the clamping rod 673 to rotate upward around the rotating shaft 675 until the clamping rod 673 is in a vertical state, supporting and longitudinally positioning the stacked angle steel layers, ensuring the stability of the angle steel stack during transportation, and further improving the safety of the entire structure during use.
