Description

Technical Field

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

[0002] Photovoltaic brackets are support components for photovoltaic power generation, and their usage is increasing. The frames of existing photovoltaic brackets mainly use C-shaped or U-shaped steel. The production process of existing C-shaped or U-shaped steel for photovoltaic brackets generally involves purchasing unprocessed coiled strip steel raw materials from suppliers, and then performing a series of processing processes such as uncoiling and feeding, forming, punching, cutting and palletizing.

[0003] Existing section steel palletizing equipment usually has the following problems: (1) When the section steel sent by the previous process is marked section steel waste, the section steel waste is usually removed from the conveyor line manually, which is not only time-consuming and laborious, but also lacks safety. (2) The flipping components of existing palletizing equipment usually drive the flipping plate to rotate by a telescopic cylinder (air cylinder), so that the section steel follows the flipping plate to rotate for flipping: on the one hand, the flipping plate serves as a supporting platform to provide support during the flipping process of the section steel. During the flipping process of the section steel, it is not clamped. Therefore, during or after the flipping process of the section steel, it is easy to shift (position deviation or front-back skew), which is not convenient for the manipulator to pick up parts and affects the palletizing efficiency; on the other hand, the flipping plate is driven by an air cylinder, and the performance of the air cylinder in terms of control accuracy, response speed, stability and reliability is slightly inferior, which will also affect the palletizing efficiency.

[0035] The following combines with the attached drawings to illustrate the detailed implementation manners of the present utility model.

[0036] As Figure 1 、 Figure 2 shown, the profiled bar palletizing machine of the present utility model includes a feeding device 100, a palletizing device 200 and a discharging device 300. The feeding device 100 includes a front conveying section 101 and a rear discharging section 102 along the conveying direction of the profiled bar.

[0037] As Figure 2As shown in the figure, a number of feeding roller tables 1 are respectively arranged at intervals along the section steel 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 feeding motors 2 are connected to each feeding roller table 1 through transmission chains to drive each feeding roller table 1 to roll and convey the section steel forward. 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 tables 1 and the feeding motors 2 of the discharging section 102 are arranged at the forward position 1021. The section steel is directly sent from the conveying section 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 section steel needs to be turned over, the turning mechanism 3 turns the section steel from the forward position 1021 to the reverse position 1022, so that the section steel is turned over by 180 degrees. Of course, if necessary, the section steel can also be turned from the reverse position 1022 to the forward position 1021 by the turning mechanism 3. A rear stop component 4 is arranged at the end of the forward position 1021 in the feeding direction. The rear stop component 4 can stop the conveyed section steel, so that the section steel stops at the designated position of the forward position 1021, which is convenient for the rapid operation of the stacking device 200 and the turning mechanism 3, ensures the accuracy of the operation, and improves the stacking efficiency; the rear stop component 4 can be adjusted back and forth along the section steel direction to adapt to section steels of different lengths.

[0038] As Figure 3 shown, the turning mechanism 3 includes a turning component 31, a turning shaft 32 and a turning motor 33. In this embodiment, a number of groups of turning components 31 are sleeved on the turning shaft 32 at intervals. One end of the turning shaft 32 is connected to the turning motor 33. The turning motor 33 drives a number of groups of turning components 31 to turn simultaneously through one turning shaft 32, ensuring the synchronism of the turning of each turning component 31, ensuring the position accuracy of the section steel after turning, and facilitating the rapid operation of the stacking device 200; the turning motor 33 is a servo motor. Compared with the cylinder drive in the prior art, the servo motor has higher control accuracy, faster response speed, better stability and reliability, which is more conducive to improving the stacking efficiency.

Padding plates made of nylon are respectively arranged on the clamping surfaces of the lower jaw plate 3111 and the upper pressing plate 3112 for clamping the section steel, and on the side surface of the pneumatic slide 3113 facing the section steel, to prevent the section steel from being scratched and ensure the surface quality of the section 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 unloading section 102, and the other side part straddles the reverse position 1022 of the unloading 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 section 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 section steel out from between the clamping surfaces of the lower jaw plate 3111 and the upper pressing plate 3112 of the clamping assembly 311; Padding plates made of nylon are respectively arranged on the surfaces of the first pusher plate 3123 and the second pusher plate 3125 in contact with the section steel, to prevent the section steel from being scratched and ensure the surface quality of the section steel. After clamping the section steel through the clamping assembly 311, the flipping mechanism 3 flips it, preventing the section 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 section steel is clamped, it is horizontally pushed by several groups of pusher assemblies 312 respectively, which can prevent the section steel from shifting in position or tilting forward and backward during movement, and is also more conducive to ensuring the position accuracy of the section steel and improving the palletizing efficiency.

[0040] As Figure 9As shown, in other embodiments, in order to achieve the 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 material blocking assembly 21 and several groups of material deflecting assemblies 22 are provided. Along the profiled steel conveying direction, the front material blocking assembly 21 is located behind several groups of material deflecting assemblies 22. When the induction device detects the marked profiled steel waste, the front material blocking assembly 21 blocks the profiled steel waste, and several groups of material deflecting assemblies 22 deflect 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 deflecting assembly 22 automatically removes the detected profiled steel waste from the conveying section 101, saving manpower and time, reducing labor costs, and also improving safety. As Figure 10 shown, the front material blocking assembly 21 includes a material blocking plate assembly 211, a rotating shaft 212 and a material blocking cylinder 213. The front material blocking assembly 21 is rotatably hinged on the rotating shaft 212. The rotating shaft 212 is fixedly connected to the conveying machine frame. The material blocking cylinder 213 is connected to the material blocking plate assembly 211. The material blocking cylinder 213 can drive the material blocking plate assembly 211 to rotate around the rotating shaft 212. When material blocking is not required, the material blocking cylinder 213 drives the material blocking plate assembly 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 material blocking is required, the material blocking cylinder 213 drives the material blocking plate assembly 211 to lift and extend upwards from the feeding roller path 1 to intercept the profiled steel waste. As Figure 11 shown, the material deflecting assembly 22 includes a base 221, a material deflecting plate 222 and a material deflecting cylinder 223.

The material deflecting cylinder 223 is connected to the material deflecting plate 222. The material deflecting cylinder 223 can drive the material deflecting plate 222 to rotate. When material deflecting is not required, the material deflecting cylinder 223 drives the material deflecting plate 222 to retract and avoid outside the profiled steel conveying track to prevent interference with the forward conveying of profiled steel. When material deflecting is required, the material deflecting cylinder 223 drives the material deflecting plate 222 to lift and deflect the profiled steel waste outwards.

The traveling motor 72 simultaneously drives the gear boxes 71 of the two traveling mechanisms 7 to travel through the first connecting shaft 76, ensuring the synchronization of traveling and improving the palletizing efficiency. The lifting mechanism 8 includes a lifting rail 81, a lifting motor 82, a lifting rack 83 and a lifting transmission gear 84. The lifting rail 81 is liftably arranged in the gear box 71.

The lifting motor 82 is fixed on the side surface of the gear box 71. The power output shaft of the lifting motor 82 horizontally penetrates through the gear box 71. The lifting transmission gear 84 is arranged in the gear box 71. The lifting transmission gear 84 is sleeved on the power output shaft of the lifting motor 82. The lifting transmission gear 84 meshes with the lifting rack 83. The lifting motor 82 drives the lifting rail 81 to perform a lifting motion through the cooperation of the lifting transmission gear 84 and the lifting rack 83. The lifting motor 82 is connected to the lifting transmission gears 84 of the lifting mechanisms 8 on the two cantilevers 6 through a second connecting shaft 85.

The clamping cylinder 18 can drive the corresponding third turning rod assembly 16-2 to slide to clamp the stacked steel sections, prevent the steel sections from tipping over, and eliminate potential safety hazards. When the discharging trolley 12 is in the stacking position (close to the feeding device 100), the second turning rod assembly 16-1, the third turning rod assembly 16-2 and the first turning rod assembly 15 / fixed stop rod 17 are respectively located outside the four corners of the discharging trolley 12. During stacking, the turning rod assemblies and the fixed stop rod 17 can define the area for stacking the steel sections, facilitating the stacking device 200 to stack the steel sections and preventing the steel sections from tipping over.The first turning rod assembly 15 includes a fixed rod 151, a turning rod 152 and a first turning rod cylinder 154.

Figure 7 As shown in the figure, 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.

After a bundle of materials is stacked, the clamping cylinder 18 drives the third turning rod assembly 16-2 to move and clamp the material stack. The lifting plate 13 descends 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 horizontal movement cylinder 20 drives the unloading trolley 12 and the third turning rod assembly 16-2 to send the material stack from 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 stack 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 horizontal 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 stacks is prepared for conveying according to the above steps. This cycle continues until all the profiled steel is palletized. While the unloading device 300 transfers a bundle of material stacks in the packing area, the palletizing work of the next bundle of material stacks is also carried out simultaneously, saving the waiting time between material feeding and palletizing and improving the palletizing efficiency.
