Description

Technical Field

[0001] The utility model relates to the technical field of punching of solar photovoltaic brackets, in particular to a discharging device of a profiled bar stacker. Background Art

[0002] Photovoltaic brackets are supporting components for photovoltaic power generation, and their usage is increasing. The frames of existing photovoltaic brackets mainly use C or U-shaped steel. The production process of existing C 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 stacking.

[0003] Existing profiled bar stacking equipment usually has the following problems: In existing stacking equipment, when stacking profiled bars, there is no limiting structure, and the profiled bars are prone to tipping over. When the stacked profiled bars are sent outwards, since the stacked profiled bars are not clamped, the profiled bars are prone to tipping over, posing a safety hazard. Summary of the Utility Model

[0004] In view of the above-mentioned shortcomings of the existing profiled bar stacking equipment, the applicant provides a discharging device of a profiled bar stacker with a reasonable structure, which is provided with a limiting structure and a clamping structure to prevent the profiled bars from tipping over and eliminate safety hazards.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A discharging device of a profiled bar stacker is provided with a discharging support on a discharging track; a transverse movement track is arranged on the discharging support. The discharging track is parallel to the profiled bar conveying direction of the feeding device, and the transverse movement track is perpendicular to the discharging track; a discharging trolley is movably arranged on the transverse movement track, and the discharging trolley is connected to a transverse movement cylinder; turning rod assemblies are respectively arranged on both sides of the discharging support. The turning rod assembly on one side can be lifted and lowered, and the turning rod assembly on the other side can be horizontally moved together with the discharging trolley.

[0007] As a further improvement of the above technical solution:

[0008] A lifting plate is arranged on one side of the discharging support. The lifting plate is connected to a lifting cylinder. Second turning rod assemblies and first fixed stop rods are arranged at intervals on the lifting plate. Third turning rod assemblies are arranged at intervals on the other side of the discharging support. The third turning rod assemblies are slidably arranged on the discharging support horizontally and are connected to a transverse movement cylinder.

[0009] A clamping cylinder is connected between two third turning rod assemblies. The cylinder block of the clamping cylinder is connected to one third turning rod assembly, and the piston rod is connected to the other third turning rod assembly.

[0010] A push plate is arranged on the discharging trolley and extends towards the third turning rod assembly.

[0011] The second turning rod assembly is slidably arranged on the lifting plate in a horizontally translatable manner.

[0012] The second turning rod assembly and the third turning rod assembly include a turning rod base, a material retaining rod, and a second turning rod cylinder. The material retaining rod is hinged to the turning rod base. The cylinder block of the second turning rod cylinder is connected to the turning rod base, and the piston rod is connected to the material retaining rod.

[0013] The first turning rod assembly and the fixed retaining rod are located on the side close to the feeding device.

[0014] The fixed rod and the turning rod of the first turning rod assembly are hinged through a hinge. The fixed rod is fixed on the lifting plate. The cylinder block of the first turning rod cylinder is connected to the fixed rod, and the piston rod is connected to the turning rod.

[0015] There are two discharging tracks. At least two discharging brackets are horizontally arranged at intervals on the two discharging tracks. A transverse track is arranged on each discharging bracket, and a discharging trolley is arranged on each transverse track respectively.

During feeding, the lifting plate is lower than the discharging trolley, and the material retaining rod of the second turning rod assembly turns down. After the stack of materials is moved out of the palletizing position, the lifting plate rises again, the material retaining rod of the second turning rod assembly stands up again, and the palletizing device continues to palletize materials. When the discharging trolley returns to its position, the material retaining rod of the third turning rod assembly turns down and moves back to the palletizing position with the discharging trolley. After returning, the material retaining rod of the third turning rod assembly stands up.

[0017] The beneficial effects of the present utility model are as follows:

[0018] When the palletizing device of the present utility model is palletizing, the turning rod assembly and the fixed retaining rod can define the area for palletizing the profiled steel, which is convenient for the palletizing device to stack the profiled steel and avoid the profiled steel from toppling. During feeding, the clamping cylinder can drive the corresponding third turning rod assembly to slide and clamp the stacked profiled steel to prevent the profiled steel from toppling and eliminate potential safety hazards. While the discharging device transfers a stack of materials in the packing area, the palletizing work of the next stack of materials is also carried out simultaneously, saving the waiting time between feeding and palletizing and improving the palletizing efficiency.

Detailed implementation manner

[0034] The following combines with the attached drawings to illustrate the detailed implementation manner of the present utility model.

[0035] 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 an unloading device 300. The feeding device 100 includes a front conveying section 101 and a rear unloading section 102 along the conveying direction of the profiled bar. The unloading device 300 is arranged on the front side of the unloading section 102. The palletizing device 200 straddles above the unloading section 102 and the unloading device 300. The palletizing device 200 can transfer the profiled bar from the unloading section 102 to the unloading device 300.

[0036] 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 unloading section 102 of the feeding device 100. Feeding motors 2 are respectively arranged on the conveying section 101 and the unloading section 102. The feeding motors 2 are connected to each feeding roller bed 1 through a transmission chain to drive each feeding roller bed 1 to roll and convey the profiled bar forward. The unloading 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 unloading 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 unloading 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 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 material retaining assembly 4 is arranged at the end of the forward position 1021 in the feeding direction. The rear material retaining assembly 4 can block and stop the conveyed profiled bar, so that the profiled bar stops at the specified position of the forward position 1021, which is convenient for the rapid operation of the palletizing device 200 and the turning mechanism 3, ensures the accuracy of the operation, and improves the palletizing efficiency; the rear material retaining assembly 4 can be adjusted back and forth along the profiled bar direction to adapt to profiled bars of different lengths.

[0037] AsFigure 3 As shown, the flipping mechanism 3 includes a flipping component 31, a flipping shaft 32 and a flipping motor 33. In this embodiment, several groups of flipping components 31 are sleeved on the flipping shaft 32 at intervals. One end of the flipping shaft 32 is connected to the flipping motor 33. The flipping motor 33 drives several groups of flipping components 31 to flip simultaneously through one flipping shaft 32, ensuring the synchronization of the flipping of each flipping component 31, ensuring the position accuracy after the section steel is flipped, and facilitating the rapid operation of the stacking device 200. The flipping 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. Moreover, the servo motor has the advantages of high efficiency, energy conservation and environmental protection, can reduce energy consumption, and will not cause pollution.

[0038] As Figure 4As shown, 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 rack. 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 clamping the profiled steel, 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.

[0039] 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. As Figure 10 shown, the front baffle component 21 includes a baffle plate component 211, a rotating shaft 212 and a baffle cylinder 213. The front baffle component 21 is rotatably hinged on the rotating shaft 212. The rotating shaft 212 is fixedly connected to the conveying machine frame. 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 material pushing plate 222 is rotatably hinged on the base 221. The material pushing cylinder 223 is connected to the material pushing plate 222. The material pushing cylinder 223 can drive the material pushing plate 222 to rotate. When material pushing is not needed, the material pushing cylinder 223 drives the material pushing plate 222 to retract and avoid outside the profiled steel conveying track to prevent interference with the forward conveying of profiled steel. When material pushing is needed, the material pushing cylinder 223 drives the material pushing plate 222 to lift and push the profiled steel waste outwards.

The traveling transmission gear 74 and the traveling transition gear 75 are arranged in the gear box 71. The traveling transmission gear 74 is sleeved on the power output shaft of the traveling motor 72. The traveling transition gear 75 is arranged between the traveling transmission gear 74 and the traveling rack 73 and meshes with the traveling transmission gear 74 and the traveling rack 73 respectively. The traveling motor 72 drives the gear box 71 to travel on the traveling rack 73 through the gear transmission structure. The traveling motor 72 is connected to the gear transmission structures of the traveling mechanisms 7 on the two cantilevers 6 through a first connecting shaft 76. 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 suction cup assembly 9 is connected to the bottom of the lifting rail 81. The lifting rack 83 is fixed on the side surface of the lifting rail 81. 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 lifting motor 82 simultaneously drives the lifting rails 81 of the two lifting mechanisms 8 to lift through the first connecting shaft 76, ensuring the synchronization of lifting and improving the palletizing efficiency. The traveling mechanism 7 and the lifting mechanism 8 of the palletizing device 200 respectively realize traveling and lifting through the gear-rack cooperation, and the positioning accuracy and stability are higher.

[0041] As Figures 6 to 8As shown, the discharging device 300 includes two discharging tracks 10 parallel to the steel conveying direction of the feeding device 100. At least two discharging supports 11 are transversely arranged at intervals on the two discharging tracks 10. A transverse movement track 111 is arranged on each discharging support 11.

A fixed stop rod 17 and a second turning rod assembly 16-1 are arranged at intervals on the lifting plate 13 of the discharging support 11 close to the end of the conveying direction. The fixed stop rod 17 is located on the side close to the feeding device 100. The second turning rod assembly 16-1 is slidably arranged on the lifting plate 13 through a slide rail. In other embodiments, the same structure can also be arranged on the lifting plate 13 of each discharging support 11, that is, a first turning rod assembly 15 and a second turning rod assembly 16-1 are arranged on each lifting plate 13, or a fixed stop rod 17 and a second turning rod assembly 16-1 are arranged. On each discharging support 11, two third turning rod assemblies 16-2 are correspondingly arranged at intervals on the other side opposite to the lifting plate 13. The two third turning rod assemblies 16-2 are slidably arranged on the discharging support 11 through a slide rail. The third turning rod assembly 16-2 is connected to the transverse movement cylinder 20, and the transverse movement cylinder 20 can drive the third turning rod assembly 16-2 to move transversely along the slide rail. A clamping cylinder 18 is connected between the two third turning rod assemblies 16-2 on this side of the discharging support 11. The cylinder seat of the clamping cylinder 18 is connected to the third turning rod assembly 16-2 close to the feeding device 100, and the piston rod is connected to the other third turning rod assembly 16-2. 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 at 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 corner positions of the discharging trolley 12. During stacking, the turning rod assemblies and the fixed stop rod 17 can define the stacking area of the steel sections, facilitate the stacking device 200 to stack the steel sections, and avoid 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. The fixed rod 151 and the turning rod 152 are hinged by a hinge 153. The fixed rod 151 is fixed on the lifting plate 13.

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 stack the profiled steel. 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 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 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 stack is prepared for transportation according to the above steps, and so on in a cycle 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.
