Description

Technical Field

[0001] This invention relates to the field of photovoltaic bracket processing, and in particular to a stacking device for channel steel used in photovoltaic brackets. Background Technology

[0002] Currently, converting solar energy into electrical energy has become a commonly used power generation technology. In order to better utilize solar energy and develop the photovoltaic industry, people often fix solar panels on photovoltaic brackets. Photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. Fixing photovoltaic brackets on the top floor of buildings and other locations allows solar panels to fully absorb solar energy.

[0003] Photovoltaic support structures are composed of multiple channel steels. Due to factors such as location and angle, the shape of photovoltaic support structures often needs to be adjusted according to changes in local terrain, sunlight angle, and other factors. During the production of channel steels for photovoltaic support structures, since the channel steels are relatively long, after the cutting machine cuts the channel steels into specific lengths, the channel steels need to be stacked to make them more neatly arranged and easier for workers to transport. The discharge port of the cutting machine is connected to a feeding rack, and a feeding roller is rotatably connected to the feeding rack. The channel steels are transported away from the cutting machine by the feeding rollers, and the robotic arm grabs and stacks the channel steels.

[0004] Regarding the aforementioned technologies, since the cutting machine can only output one channel steel at a time, after the robotic arm picks up and stacks the channel steel, it needs to wait for the next channel steel to be cut, resulting in low stacking efficiency. Summary of the Invention

[0005] To improve stacking efficiency, this invention provides a stacking device for channel steel used in photovoltaic brackets.

[0006] The present invention provides a stacking device for channel steel for photovoltaic brackets, which adopts the following technical solution:

[0007] A stacking device for channel steel for photovoltaic brackets includes a support mechanism and a feeding mechanism connected to the support mechanism for conveying the channel steel. It also includes a pushing mechanism, a handling mechanism for transporting the channel steel, and a controller. The pushing mechanism includes a push plate for pushing the channel steel, a second sensing plate, and a pushing element for pushing the push plate. The second sensing plate is connected to the feeding mechanism. A sensing element for sensing whether the channel steel is in contact with the second sensing plate is connected to the second sensing plate. The controller is electrically connected to the sensing element and the pushing element.

[0008] By adopting the above technical solution, the support mechanism can receive the channel steel output from the cutting machine outlet, and the feeding mechanism enables the channel steel to move along the length of the feeding frame. When the channel steel moves to contact the second induction plate, the induction element can convert the sensed signal into an electrical signal and send it to the controller. The controller then controls the push plate to push the channel steel in a direction perpendicular to the length of the feeding frame. This allows the support mechanism to continue receiving the channel steel conveyed from the cutting machine while the handling mechanism is handling the channel steel, thereby improving the stacking efficiency of the channel steel.

[0009] Preferably, the support mechanism includes a feeding frame, and the feeding mechanism includes a feeding roller, a transmission roller and a transmission motor for conveying the channel steel. The feeding roller and the transmission roller are rotatably connected to the feeding frame. Multiple transmission rollers are provided and connected to each other by sprockets and chains. The rotation shaft of one of the transmission rollers is fixedly connected to the output end of the transmission motor.

[0010] By adopting the above technical solution, the feeding rack can support the feeding roller, which supports the channel steel, making it less likely to fall off the stacking rack. When the channel steel in front is pushed, the channel steel produced later can stay on the feeding roller for a period of time to prevent interference between the channel steels. The transmission roller can further transmit the channel steel under the action of the transmission motor. The sensing element can control when the transmission roller transmits the channel steel, making the transportation more controllable and improving the stacking efficiency.

[0011] Preferably, the pushing mechanism includes a first sensing plate located between the feeding roller and the transmission roller. The first sensing plate is rotatably connected to the feeding frame. A sensing element is connected to the feeding frame connected to the first sensing plate. The transmission motor, the sensing element connected to the first sensing plate, and the controller are electrically connected.

[0012] By adopting the above technical solution, when the channel steel comes into contact with the first sensing plate and presses down on the first sensing plate, the transmission motor works to make the transmission roller start to rotate, and the channel steel is transported away from the cutting machine, so that the channel steel can enter the feeding rack in an orderly manner.

[0013] Preferably, a limiting mechanism is connected to the feeding rack. The limiting mechanism includes a limiting plate, which is hinged to the side of the first sensing plate and the second sensing plate away from the push plate. A tension spring is connected to the position where the first sensing plate and the second sensing plate are hinged to the limiting plate.

[0014] By adopting the above technical solution, the limiting plate can further limit the horizontal movement of the channel steel during the conveying process, prevent the channel steel from shifting due to vibration, and affect the pushing effect of the push plate. When the push plate pushes the channel steel to move closer to the flipping mechanism, the channel steel abuts against the limiting plate and pushes the limiting plate under the pushing force of the push plate. After the channel steel is pushed past the limiting plate, the limiting plate resets, and at the same time restricts the position of the channel steel pushed out of the limiting plate.

[0015] Preferably, the feeding frame is connected to a feeding beam and a storage platform. The two ends of the feeding beam are fixedly connected to two opposite sides of the feeding frame. The first sensing plate and the second sensing plate are hinged to the feeding beam. The storage platform is located on the side of the feeding frame away from the push plate and is fixedly connected to the feeding frame. The length direction of the storage platform is parallel to the length direction of the feeding frame. The limiting mechanism further includes a limiting member and a baffle for limiting the position of the channel steel. The limiting member is connected to the storage platform and is located on the top surface of the storage platform on the side away from the feeding frame. The baffle is fixedly connected to both ends of the storage platform. A sensing member is connected to the baffle and is connected to the controller.

[0016] By adopting the above technical solutions, the feeding beam can increase the overall strength of the feeding rack, making it more stable when transporting channel steel. At the same time, the connection between the first and second sensing plates and the feeding beam ensures that the rotation of the first and second sensing plates will not affect the normal operation of the transmission rollers. The limiting component and the baffle can prevent the channel steel from falling off the feeding rack and the storage platform. When the channel steel comes into contact with the baffle, the sensing component transmits a signal to the controller to stop the transmission motor, which facilitates the pusher plate to push the channel steel and improves the stacking efficiency.

[0017] Preferably, the pushing component is a pushing cylinder, the body of the pushing cylinder is fixedly connected to the feeding frame, and the piston rod of the pushing cylinder is fixedly connected to the side of the pushing plate away from the feeding frame.

[0018] By adopting the above technical solution, the pusher cylinder can stably make the pusher plate slide in a direction perpendicular to the length of the feeder.

[0019] Preferably, the feeding rack is connected to a flipping mechanism, which is located on one side of the feeding rack. The flipping mechanism includes a positioning sleeve, a flipping ring, and a flipping motor. The support mechanism includes a flipping frame, which is close to the storage platform. The positioning sleeve is fixedly connected to the top surface of the flipping frame. The flipping ring is located inside the positioning sleeve and is rotatably connected to the positioning sleeve. The flipping motor is connected to the flipping ring to flip the flipping ring.

[0020] By adopting the above technical solution, the positioning sleeve facilitates a more accurate connection between the channel steel transported by the handling mechanism and the flipping ring. The flipping ring can flip the channel steel under the action of the flipping motor, so that the channel steel can be stored in a forward and reverse interlocking form when stacking, thereby saving storage space.

[0021] Preferably, the handling mechanism includes a robotic arm and a base for rotating the robotic arm. A gripper for handling the channel steel is fixedly connected to the robotic arm. The robotic arm is connected to the base. The support mechanism includes a stacking rack for storing the channel steel. Limiting posts are fixedly connected to the stacking rack. Multiple limiting posts are provided and are respectively close to the edge of the stacking rack.

[0022] By adopting the above technical solution, the channel steel can be transported through the cooperation of the robotic arm and the base, saving manpower and increasing the automation rate of channel steel handling, as well as improving the stacking efficiency of channel steel. The stacking rack facilitates the robotic arm to stack channel steel in specific positions, and the limiting posts prevent the stacked channel steel from slipping off the stacking rack, thus improving stacking efficiency.

[0023] Preferably, the sensing element is a pressure sensor, which is located below the first sensing plate, the second sensing plate, and on the side of the baffle near the feeding rack.

[0024] By adopting the above technical solution, when the channel steel presses down on the first and second sensing plates, the pressure sensor can convert the sensed pressure signal into an electrical signal, and under the action of the controller, start the transmission motor or push the cylinder.

[0025] Preferably, the limiting component is a limiting roller, and multiple limiting rollers are provided. The limiting rollers are rotatably connected to the top surface of the storage platform on the side away from the feeding frame.

[0026] By adopting the above technical solution, the limiting roller can prevent the channel steel from falling off the storage platform, making it easy to store on the storage platform and wait for the robotic arm to pick it up for subsequent stacking work.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. When the channel steel is output from the outlet of the cutting machine, the feeding mechanism can receive the channel steel. When the channel steel is conveyed forward to abut against the second induction plate, the push plate can be pushed by the controller to allow subsequent channel steel to continue to be conveyed on the feeding mechanism, thereby improving the stacking efficiency of the channel steel.

[0029] 2. During the conveying process, when the channel steel presses down on the first sensing plate, the transmission motor drives the transmission roller to start rotating. When the channel steel comes into contact with the baffle, the transmission roller stops rotating. This not only achieves energy saving, but also prevents the channel steel in the transportation process and the channel steel that is pushed away from each other from affecting each other.

[0030] 3. The flipping mechanism can flip the channel steel, and the robotic arm can pick up and stack the flipped channel steel. The channel steel with the opening facing up and the channel steel with the opening facing down can be interlocked, which can save space and stack more channel steel. Attached Figure Description

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] A stacking device for channel steel used in photovoltaic brackets, such as Figure 1 and Figure 2 As shown, the system includes a support mechanism 1, a feeding mechanism 2, a pushing mechanism 3, a limiting mechanism 4, a flipping mechanism 5, a transport mechanism 6, and a controller (not shown in the figure). The feeding mechanism 2 is connected to the support mechanism 1 to transport the channel steel away from the cutting machine. The pushing mechanism 3 is connected to the feeding mechanism 2 to push the channel steel on the feeding mechanism 2 so that the channel steel is detached from the feeding mechanism 2. The limiting mechanism 4 is connected to the support mechanism 1, the pushing mechanism 3, and the feeding mechanism 2 to restrict the horizontal movement of the channel steel so that the channel steel is not easy to fall off the support mechanism 1. The flipping mechanism 5 is located on one side of the feeding mechanism 2 and is used to flip the channel steel with the opening facing upward to the opening facing downward, which is convenient for subsequent stacking. The transport mechanism 6, which is used to transport the channel steel, is located above the support mechanism 1. The controller is used to maintain the normal operation of the circuit.

[0037] like Figure 1As shown, the support mechanism 1 includes a feeding frame 11, a tilting frame 12, and a stacking frame 13. The feeding frame 11 includes a horizontal section and multiple vertical sections. The length direction of the horizontal section of the feeding frame 11 is parallel to the material output direction of the cutting machine, and one end of the feeding frame 11 is close to the material output port of the cutting machine. Multiple vertical sections are symmetrically fixedly connected to the bottom surface of the horizontal section. Multiple feeding beams 111 are fixedly connected between the horizontal sections of the feeding frame 11. The length direction of the feeding beams 111 is perpendicular to the length direction of the feeding frame 11.

[0038] like Figure 1 As shown, a storage platform 112 is fixedly connected to one side of the feeding rack 11. The storage platform 112 is a rectangular plate structure with a length equal to that of the feeding rack 11. A vertical tilting frame 12 is located on the side of the storage platform 112 away from the feeding rack 11, and the tilting frame 12 is close to the discharge port of the cutting machine.

[0039] like Figure 2 As shown, the feeding mechanism 2 includes a feeding roller 21, a transmission roller 22, a feeding motor 23, and a transmission motor 24. The length directions of the feeding roller 21 and the transmission roller 22 are perpendicular to the length direction of the feeding frame 11, and the feeding roller 21 and the transmission roller 22 are rotatably connected to two opposite sides of the feeding frame 11. The feeding roller 21 is located at the end of the feeding frame 11 near the cutting machine, and the top surface of the feeding roller 21 is flush with the top surface of the storage platform 112. The output end of the feeding motor 23 is fixedly connected to the rotating shaft of the feeding roller 21 to make the feeding roller 21 rotate.

[0040] like Figure 2 As shown, multiple transmission rollers 22 are provided, and the multiple transmission rollers 22 are located on the side of the feeding roller 21 away from the feeding roller 21. The transmission rollers 22 are alternately connected to the feeding beam 111 on the feeding frame 11. The transmission motor 24 is electrically connected to the controller. The output end of the transmission motor 24 is fixedly connected to the rotating shaft of one of the transmission rollers 22. The transmission rollers 22 are connected to each other through sprockets and chains. When the transmission motor 24 drives the transmission roller 22 connected to it to rotate, the other transmission rollers 22 rotate at the same time.

[0041] like Figure 1 As shown, the pushing mechanism 3 includes a push plate 31, a first sensing plate 32, a second sensing plate 33, and a pushing component. The pushing component can be a linear motor or a pushing cylinder 34. In this embodiment, a pushing cylinder 34 is used. The push plate 31 is a vertical rectangular plate structure with its length direction parallel to the length direction of the feeding frame 11. The push plate 31 is located above the side of the transmission roller 22 away from the storage platform 112. The end of the push plate 31 near the feeding roller is inclined away from the feeding frame 11 to guide the channel steel that has shifted position back onto the transmission roller 22. A bracket for supporting the pushing cylinder 34 is fixedly connected to the side of the feeding frame 11 away from the storage platform 112. The body of the pushing cylinder 34 is fixedly connected to the bracket, and the piston rod of the pushing cylinder 34 is fixedly connected to the push plate 31 to push the push plate 31 to move towards the storage platform 112.

[0042] like Figure 1 and Figure 2 As shown, the first sensing plate 32 and the second sensing plate 33 are arc-shaped plate structures with the same shape. Both the first sensing plate 32 and the second sensing plate 33 are hinged to the feeding beam 111. The first sensing plate 32 is located between the feeding roller 21 and the transmission roller 22, and the second sensing plate 33 is located at the end of the feeding frame 11 away from the cutting machine.

[0043] like Figure 1 and Figure 2 As shown, sensing elements are fixedly connected to the top surface of the feeding beam 111 connected to the first sensing plate 32 and the second sensing plate 33, respectively. The sensing elements can be force sensors or micro switches. In this embodiment, a force sensor is used. The force sensor is electrically connected to the controller. When the channel steel presses down on the first sensing plate 32, the force sensor that abuts against the first sensing plate 32 receives the pressure signal and converts it into an electrical signal and sends it to the controller. The controller controls the transmission motor 24 to work, so that the transmission roller 22 starts to rotate under the action of the transmission motor 24, thereby conveying the channel steel forward. When the channel steel continues to be conveyed forward to press down on the second sensing plate 33, the force sensor that abuts against the second sensing plate 33 converts the pressure signal into an electrical signal. The controller controls the pushing cylinder 34 to work, and the pushing plate 31 pushes the channel steel to move towards the overturning mechanism 5, leaving space for the channel steel to be conveyed later.

[0044] In use, the feeding roller 21 rotates under the action of the feeding motor 23. After the channel steel is output from the outlet of the cutting machine, it comes into contact with the feeding roller 21. The channel steel is conveyed away from the cutting machine and comes into contact with the transmission roller 22. When the channel steel presses down on the first sensing plate 32, the transmission roller 22 starts to rotate under the action of the controller, so that the channel steel continues to be conveyed forward until it presses down on the second sensing plate 33. The controller controls the push plate 31 to push the channel steel towards the side closer to the flipping mechanism 5.

[0045] like Figure 1 and Figure 2 As shown, the limiting mechanism 4 includes a limiting plate 41, a limiting member, a baffle 43, and a limiting post 44. The limiting plate 41 is an arc-shaped plate structure, which is hinged to the side of the first sensing plate 32 and the second sensing plate 33 near the flipping mechanism 5. The limiting plate 41 is connected to the first sensing plate 32 and the second sensing plate 33 respectively by a tension spring. When the channel steel is pushed to the first sensing plate 32 or the second sensing plate 33, the limiting plate 41 rotates downward under the pushing action of the channel steel until it is flush with the top surface of the first sensing plate 32 or the second sensing plate 33.

[0046] like Figure 1As shown, the limiting component can be a vertical limiting roller 42 or a square plate structure that blocks the channel steel. In this embodiment, the limiting roller 42 is used. There are two limiting rollers 42, which are rotatably connected to the top surface of the storage platform 112 away from the feeding frame 11. The roller body of the limiting roller 42 is made of rubber material, which can reduce the vibration and friction when the channel steel is pushed to abut against the limiting roller 42.

[0047] like Figure 1 and Figure 2 As shown, the baffle 43 is a vertical rectangular plate structure, and its length direction is perpendicular to the length direction of the feeding rack 11. There are two baffles 43, which are fixedly connected to the top surfaces of both ends of the storage platform 112. The baffle 43 closer to the cutting machine is connected to both sides of the storage platform 112 along its length direction. The baffle 43 farther from the cutting machine is connected at one end to the top surface of the storage platform 112 away from the feeding rack 11, and at the other end to the top surface of the feeding rack 11 away from the storage platform 112. A force sensor is fixedly connected to the baffle 43 away from the cutting machine. The force sensor is electrically connected to the controller. When one end of the channel steel abuts against the baffle 43, the controller controls the transmission motor 24 to stop.

[0048] In use, the limiting plate 41 prevents the channel steel transported on the conveying roller 22 from being displaced horizontally due to vibration. When the push plate 31 pushes the channel steel toward the turning mechanism 5, the limiting plate 41 rotates downward under the push of the channel steel, so that the channel steel is smoothly pushed into the storage platform 112. As the channel steel is continuously pushed toward the storage platform 112, when the channel steel comes into contact with the limiting roller 42, the elasticity of the roller body of the limiting roller 42 can reduce the wear caused by the collision. The baffle 43 can limit the channel steel and prevent the channel steel from falling off the feeding rack 11 and the storage platform 112.

[0049] like Figure 1 As shown, the flipping mechanism 5 includes a positioning sleeve 51, a flipping ring 52, and a flipping motor 53. The positioning sleeve 51 and the flipping ring 52 are arranged in two sets and are respectively connected to two flipping frames 12. The positioning sleeve 51 is a hollow cylindrical structure, and its bottom surface is fixedly connected to the top surface of the flipping frame 12. The top surface of the positioning sleeve 51 is flush with the top surface of the storage platform 112. The top surface of the positioning sleeve 51 has a hole for the channel steel to enter, and two auxiliary channel steel plates extend upward from the top surface of the positioning sleeve 51 to enter the positioning sleeve 51. The two plates are inclined in a direction away from each other.

[0050] like Figure 1 and Figure 2 As shown, the flip ring 52 is located inside the positioning sleeve 51 and is rotatably connected to the positioning sleeve 51. The positioning sleeve 51 has a hole for the rotating shaft of the flip ring 52 to extend out of the positioning sleeve 51. The flip motor 53 is connected to the rotating shaft of the flip ring 52. When the output end of the flip motor 53 rotates, the flip ring 52 drives the channel steel to flip, so that the opening of the channel steel faces downward.

[0051] In use, the channel steel to be flipped is placed into the positioning sleeve 51, and the channel steel is engaged with the flipping ring 52. Under the action of the flipping motor 53, the channel steel can be flipped.

[0052] like Figure 1 As shown, the handling mechanism 6 includes a robotic arm 61 and a base 62. One end of the robotic arm 61 is rotatably connected to a gripper 611 for gripping the channel steel on the storage platform 112, and the other end is rotatably connected to the base 62, making the movement of the robotic arm 61 more flexible.

[0053] The usage process of this invention is as follows:

[0054] The channel steel output from the cutting machine's outlet comes into contact with the feeding roller 21 and is conveyed forward under the rotation of the feeding roller 21. After passing through the feeding roller 21, the channel steel presses down on the first sensing plate 32, causing the sensor below the first sensing plate 32 to transmit a signal to the controller, which causes the transmission motor 24 to work, and the transmission roller 22 to start rotating. The channel steel continues to be transported on the transmission roller 22 until it presses down on the second sensing plate 33, which causes the pushing cylinder 34 to work and push the push plate 31 to push the channel steel towards the storage platform 112. When the channel steel comes into contact with the baffle 43, the transmission motor 24 stops working.

[0055] As the cutting machine continuously outputs channel steel, the channel steel on the storage platform 112 gradually accumulates on the limit of the baffle 43 until it comes into contact with the limit roller 42. The robotic arm 61 moves to the point where the gripper 611 aligns with the channel steel on the storage platform 112, grabs the channel steel, and stacks it on the stacking rack 13. When it is necessary to flip the channel steel, the robotic arm 61 grabs the channel steel and places both ends of the channel steel into the positioning sleeve 51. The channel steel is flipped under the action of the flipping ring 52 and is taken out by the robotic arm 61 to continue stacking.

[0056] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
