Description

Technical Field

[0001] The utility model relates to the technical field of punching holes in solar photovoltaic brackets, in particular to a steel section stacker. Background Art

[0002] Photovoltaic racks are the supporting components for photovoltaic power generation, and their use is increasing. Existing rack frames primarily use C- or U-shaped steel. The production process for these C- or U-shaped steel racks typically involves purchasing unprocessed coiled steel from suppliers and then performing a series of processing steps, including unwinding, forming, punching, cutting, and stacking.

[0003] The existing steel section stacking equipment usually has the following problems: (1) When the steel section sent from the previous process is marked steel section scrap, it is usually removed from the conveyor line manually, which is not only time-consuming and labor-intensive, but also unsafe. (2) The flipping assembly of the existing stacking equipment is usually driven by a telescopic cylinder (pneumatic cylinder) to rotate the flip plate, so that the steel section rotates with the flip plate to achieve flipping: on the one hand, the flip plate provides support as a supporting platform during the steel section flipping process. During the steel section flipping process, it is not clamped. Therefore, the steel section is prone to displacement (position offset or skewed forward and backward) during or after flipping, which is not convenient for the robot to pick up the parts and affects the stacking efficiency. On the other hand, the flip plate is driven by a pneumatic cylinder, and the performance of the cylinder in terms of control accuracy, response speed, stability and reliability is slightly inferior, which also affects the stacking efficiency. (3) The walking mechanism and lifting mechanism on the stacking device of the existing stacking equipment usually adopt linear guides or chain drives to achieve walking or lifting, and the positioning accuracy and stability are not high enough. (4) When the steel sections are stacked and sent out, the unloading device of the existing stacking equipment is prone to tipping over because the stacked steel sections are not clamped, posing a safety hazard.

[0039] As Figure 2 shown, a number of feeding roller beds 1 are respectively arranged at intervals along the profiled bar conveying direction on the conveying section 101 and the discharging section 102 of the feeding device 100. Feeding motors 2 are respectively arranged on the conveying section 101 and the discharging section 102.

The discharging section 102 includes a forward position 1021 at the rear side and a reverse position 1022 at the front side. The conveying center of the forward position 1021 is on the same straight line as the conveying center of the conveying section 101. The feeding roller beds 1 and the feeding motors 2 of the discharging section 102 are arranged at the forward position 1021. The profiled bar is directly sent from the conveying section 101 to the forward position 1021 of the discharging section 102. A turning mechanism 3 is arranged between the forward position 1021 and the reverse position 1022. When the profiled bar needs to be turned over, the turning mechanism 3 turns the profiled bar from the forward position 1021 to the reverse position 1022, so that the profiled bar is turned over by 180 degrees. Of course, if necessary, the profiled bar can also be turned from the reverse position 1022 to the forward position 1021 by the turning mechanism 3. A rear baffle assembly 4 is arranged at the end of the forward position 1021 in the feeding direction. The rear baffle assembly 4 can block and stop the conveyed profiled bar, so that the profiled bar stops at the designated position of the forward position 1021, which is convenient for the quick operation of the palletizing device 200 and the turning mechanism 3, ensures the accuracy of the operation and improves the palletizing efficiency; the rear baffle assembly 4 can be adjusted back and forth along the profiled bar direction to adapt to profiled bars of different lengths.

Compared with the cylinder drive in the prior art, the servo motor has higher control accuracy, faster response speed, better stability and reliability, is more conducive to improving the palletizing efficiency, and the servo motor has the advantages of high efficiency, energy conservation and environmental protection, can reduce energy consumption, and will not cause pollution.

[0041] As Figure 4As shown in the figure, the flipping assembly 31 of the flipping mechanism 3 includes a clamping assembly 311 and a pusher assembly 312; the clamping assembly 311 is fixedly sleeved on the flipping shaft 32, and the clamping assembly 311 can flip together with the flipping shaft 32. The clamping assembly 311 includes a lower jaw plate 3111, an upper pressing plate 3112 and a pneumatic slide 3113. The lower jaw plate 3111 is fixedly sleeved on the flipping shaft 32, the pneumatic slide 3113 is fixed on the lower jaw plate 3111, the upper pressing plate 3112 is slidably arranged on the pneumatic slide 3113, and the pneumatic slide 3113 can drive the upper pressing plate 3112 to slide up and down to loosen or clamp the profiled steel. Nylon pads are respectively arranged on the clamping surfaces of the lower jaw plate 3111 and the upper pressing plate 3112 for clamping the profiled steel and on the side surface of the pneumatic slide 3113 facing the profiled steel to prevent the profiled steel from being scratched and ensure the surface quality of the profiled steel. The pusher assembly 312 includes a mounting plate 3121 fixed on the feeding machine frame. One side part of the mounting plate 3121 straddles the forward position 1021 of the discharging section 102, and the other side part straddles the reverse position 1022 of the discharging section 102. A first pusher cylinder 3122 is arranged on the side part of the mounting plate 3121 located at the forward position 1021. A first pusher plate 3123 is arranged on the first pusher cylinder 3122 facing the clamping assembly 311. The first pusher cylinder 3122 can drive the first pusher plate 3123 to move and push the profiled steel into the clamping surface between the lower jaw plate 3111 and the upper pressing plate 3112 of the clamping assembly 311. A second pusher cylinder 3124 is arranged on the side part of the mounting plate 3121 located at the reverse position 1022. A second pusher plate 3125 is arranged on the second pusher cylinder 3124 facing away from the clamping assembly 311. The second pusher cylinder 3124 can drive the second pusher plate 3125 to move and push the flipped profiled steel out from between the clamping surfaces of the lower jaw plate 3111 and the upper pressing plate 3112 of the clamping assembly 311. Nylon pads are respectively arranged on the surfaces of the first pusher plate 3123 and the second pusher plate 3125 in contact with the profiled steel to prevent the profiled steel from being scratched and ensure the surface quality of the profiled steel. After clamping the profiled steel through the clamping assembly 311, the flipping mechanism 3 flips it, preventing the profiled steel from shifting during or after flipping, ensuring the position accuracy after flipping, facilitating the rapid operation of the palletizing device 200, and improving the palletizing efficiency; moreover, before and after the profiled steel is clamped, it is horizontally pushed by several groups of pusher assemblies 312 respectively, which can prevent the profiled steel from shifting in position or tilting forward and backward during movement, and is also more conducive to ensuring the position accuracy of the profiled steel and improving the palletizing efficiency.

[0042] As Figure 9As shown, in other embodiments, in order to achieve automatic removal of profiled steel waste, an induction device (not shown in the figure) may be provided on the conveying section 101 of the feeding device 100. At the same time, a front baffle component 21 and several groups of material pushing components 22 are provided. Along the profiled steel conveying direction, the front baffle component 21 is located behind several groups of material pushing components 22. When the induction device detects the marked profiled steel waste, the front baffle component 21 blocks the profiled steel waste, and several groups of material pushing components 22 push the profiled steel waste outwards from the conveying section 101, thus realizing the automatic removal of profiled steel waste, saving time and effort and improving safety. The material pushing component 22 automatically removes the detected profiled steel waste from the conveying section 101, saving manpower and time, reducing labor costs, and also improving safety.

The baffle cylinder 213 is connected to the baffle plate component 211. The baffle cylinder 213 can drive the baffle plate component 211 to rotate around the rotating shaft 212. When baffle is not needed, the baffle cylinder 213 drives the baffle plate component 211 to retract and hide under the feeding roller path 1 of the conveying section 101 to prevent interference with the forward conveying of profiled steel. When baffle is needed, the baffle cylinder 213 drives the baffle plate component 211 to lift and extend upwards from the feeding roller path 1 to intercept the profiled steel waste. As Figure 11 shown, the material pushing component 22 includes a base 221, a material pushing plate 222 and a material pushing cylinder 223. The base 221 is fixed on the conveying machine frame.

The cylinder block of the first turning rod cylinder 154 is connected to the fixed rod 151, and the piston rod is connected to the turning rod 152. The first turning rod cylinder 154 can drive the turning rod 152 to stand up or turn down. The second turning rod assembly 16-1 and the third turning rod assembly 16-2 have the same structure, and both include a turning rod seat 161, a material retaining rod 162 and a second turning rod cylinder 163. The turning rod seat 161 of the second turning rod assembly 16-1 is slidably arranged on the lifting plate 13, and the turning rod seat 161 of the third turning rod assembly 16-2 is slidably arranged on the slide rail of the unloading support 11. The material retaining rod 162 is hinged to the turning rod seat 161. The cylinder block of the second turning rod cylinder 163 is connected to the turning rod seat 161, and the piston rod is connected to the material retaining rod 162. The second turning rod cylinder 163 can drive the material retaining rod 162 to stand up or turn down. As. Figure 7 As shown, on the unloading trolley 12, push plates 19 are respectively extended and arranged facing the two third turning rod assemblies 16-2. The push plates 19 serve as mechanical limit members and play a limiting role. During palletizing, the unloading trolley 12 is horizontally moved to the palletizing position, the lifting plate 13 is raised to a position higher than the unloading trolley 12, the turning rod 152 of the first turning rod assembly 15 and the material retaining rods 162 of the second turning rod assembly 16-1 and the third turning rod assembly 16-2 stand up, and the palletizing device 200 starts to palletize the profiled steel. After a bundle of materials is palletized, the clamping cylinder 18 drives the third turning rod assembly 16-2 to move and clamp the material stack. The lifting plate 13 is lowered to a position lower than the unloading trolley 12, and the material stack is placed on the unloading trolley 12 along with the trend. The material retaining rod 162 of the second turning rod assembly 16-1 on the lifting plate 13 turns down. The transverse movement cylinder 20 drives the unloading trolley 12 and the third turning rod assembly 16-2 to send the material stack out of the palletizing position to the packing area. After the material stack is removed from the palletizing position, the lifting plate 13 rises again, and the material retaining rod 162 of the second turning rod assembly 16-1 on the lifting plate 13 stands up again. The palletizing device 200 continues to palletize the materials. When the unloading trolley 12 horizontally moves the material stack to the packing area, the third turning rod assembly 16-2 that moves out horizontally with the unloading trolley 12 turns down its material retaining rod 162, and then the transverse movement cylinder 20 drives the unloading trolley 12 and the two third turning rod assemblies 16-2 to move back to the palletizing position. After returning, the material retaining rods 162 of the two third turning rod assemblies 16-2 stand up, and the next bundle of material stack is conveyed according to the above steps. This cycle continues until all the profiled steel palletizing work is completed. While the unloading device 300 transfers a bundle of material stack in the packing area, the palletizing work of the next bundle of material stack is also carried out simultaneously, saving the waiting time between material feeding and palletizing and improving the palletizing efficiency.
