Description

Technical Field

[0001] This utility model relates to the field of sheet metal conveying and stacking technology, and in particular to an automatic double-layer belt stacking device suitable for sheet metal conveying. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for metal sheets less than 6mm thick. Through processes such as shearing, punching / cutting, bending, welding, riveting, splicing, and forming, metal sheets are processed into parts or products with specific shapes and functions. After sheet metal laser cutting, the sheet metal materials are then conveyed and stacked.

[0003] Currently, sheet metal manufacturers typically operate by having laser-cut sheet metal materials flow into a belt conveyor, where each piece is manually removed from the conveyor before being transferred to the bending process. While this production method is simple in structure, it increases manpower and reduces production efficiency. Therefore, those skilled in the art have developed a double-layer belt automatic stacking device suitable for sheet metal conveying to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a double-layer belt automatic stacking device suitable for sheet metal conveying. The device uses a telescopic structure to drive a small belt conveyor to move back and forth. After moving to the material tray, the small belt conveyor starts to convey the sheet metal parts. During the start-up process, the small belt conveyor is driven backward to facilitate the stacking of sheet metal parts on the material tray.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a double-layer belt automatic stacking device suitable for sheet metal conveying, comprising a mounting frame, a large belt conveyor fixedly connected to the upper part of the mounting frame, a telescopic structure fixedly connected to the front part of the mounting frame, a small belt conveyor fixedly connected to the upper part of the telescopic structure, a bracket fixedly connected to the front part of the upper end face of the mounting frame, and a sensing device fixedly connected to the front end face of the bracket.

[0006] The telescopic structure includes a frame, the small belt conveyor is fixedly connected to the inner side of the frame, support rods are fixedly connected to the front of both sides of the lower end face of the frame, hubs are rotatably connected to the lower ends of the two support rods, and rails are provided at the lower ends of the two hubs. Guide rails are provided on both sides of the lower end face of the frame, and a first support frame is fixedly connected inside the mounting bracket at the lower end of the two guide rails. Electric telescopic rods are fixedly connected to the center of the rear end face of the two guide rails, and the output ends of the two electric telescopic rods pass through the rear end face of the two guide rails and extend into the interior of the two guide rails, and the ends are fixedly connected to the rear end face of the frame.

[0007] Through the above technical solution, two electric telescopic rods push the frame forward along two guide rails, which in turn moves the two support rods forward. The two wheel hubs roll on the two tracks, causing the equipment to move forward until it reaches the top of the material tray and stops. At this point, the small belt conveyor is started to transport the sheet metal material on the small belt conveyor forward. During the conveying process, the two electric telescopic rods are controlled to retract synchronously, and the sheet metal material falls forward onto the top surface of the material tray. The small belt conveyor returns to its initial position, and the operation is repeated to stack the cut sheet metal material on the material tray. Then, a forklift is used to transport the material tray and the stacked sheet metal material together, which significantly improves production efficiency.

[0008] Furthermore, a second support frame is fixedly connected to the upper end surface of the first support frame at the lower end of each of the two electric telescopic rods, and the two second support frames are supported on the lower part of the outer side wall of the two electric telescopic rods;

[0009] The above technical solution facilitates the use of two second support frames to provide support for the two electric telescopic poles, thereby improving stability.

[0010] Furthermore, a fixing plate is fixedly connected to the rear end face of the two tracks;

[0011] The above technical solution connects the two tracks using a fixing plate, increasing the stability of the two tracks.

[0012] Furthermore, an auxiliary structure is provided at the front of the two tracks. The auxiliary structure includes two first pillars arranged laterally. A hydraulic jack is provided at the rear end of each of the two first pillars. A second pillar is provided at the rear end face of each of the two hydraulic jacks. A material tray is provided between the two hydraulic jacks. Grooves are provided on both sides of the lower end face of the material tray. Guide grooves are provided on the front and rear inner side walls of the two grooves. The two grooves are respectively fitted onto the upper end face of the two hydraulic jacks.

[0013] The above technical solution controls the start of two hydraulic jacks to lift the material tray upwards. After the material is unloaded, the two hydraulic jacks are lowered by the thickness of one sheet metal piece. The small belt conveyor returns to its initial position, and the operation is repeated to reduce damage to the sheet metal due to height during stacking.

[0014] Furthermore, a baffle is fixedly connected to the front of the upper end face of the two first pillars, and a rubber pad is fixedly connected to the rear end face of the baffle. A connecting column is fixedly connected to the upper center of the front end face of the two second pillars, and the two connecting columns are respectively fixedly connected to the rear end face of the first pillar.

[0015] Through the above technical solution, the sheet metal is conveyed forward and impacts the rubber pad before falling onto the upper surface of the material tray, reducing the impact force generated when falling. Two connecting columns connect the two first pillars and the two second pillars. The fixed ends of the two hydraulic jacks are fixedly connected to the first and second pillars, which facilitates the improvement of overall stability.

[0016] Furthermore, forklift fork slots are provided on both sides of the lower end face of the material tray;

[0017] The above technical solution involves inserting the forklift forks into the two forklift slots to transport the pallet and stacked sheet metal together, thereby significantly improving production efficiency.

[0018] Furthermore, each of the four opposite corners of the lower end face of the mounting bracket is fixedly connected with a support leg;

[0019] The above technical solution facilitates the provision of support for the mounting frame.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, two electric telescopic rods push the frame forward along two guide rails, which in turn moves the two support rods forward. The two wheel hubs roll on the two tracks, causing the equipment to move forward until it reaches the top of the material tray. At this point, the small belt conveyor is started, transporting the sheet metal material on it forward. During the transport process, the two electric telescopic rods retract synchronously, causing the sheet metal material to fall forward onto the top surface of the material tray. The small belt conveyor then returns to its initial position, and this operation is repeated to stack the cut sheet metal material onto the material tray. Finally, a forklift transports the material tray and the stacked sheet metal material together, significantly improving production efficiency.

[0022] In this invention, two hydraulic jacks are controlled to start and lift the material tray upwards. After the material is released, the two hydraulic jacks are controlled to lower the tray by the thickness of one sheet metal piece. The small belt conveyor returns to the initial position, and the operation is repeated to reduce damage to the sheet metal due to height when stacking it. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-4 An embodiment of this utility model is provided: a double-layer belt automatic stacking device suitable for sheet metal conveying, including a mounting frame 1, a large belt conveyor 6 fixedly connected to the upper part of the mounting frame 1, a telescopic structure 2 fixedly connected to the front part of the mounting frame 1, a small belt conveyor 4 fixedly connected to the upper part of the telescopic structure 2, a bracket 7 fixedly connected to the front part of the upper end face of the mounting frame 1, and a sensing device 8 fixedly connected to the front end face of the bracket 7.

[0033] like Figure 1 , 2As shown in Figure 3, the telescopic structure 2 includes a frame 205. A small belt conveyor 4 is fixedly connected to the inside of the frame 205. Support rods 203 are fixedly connected to the front of both sides of the lower end face of the frame 205. Hubs 204 are rotatably connected to the lower ends of the two support rods 203. Rails 201 are provided at the lower ends of the two hubs 204. Guide rails 206 are provided on both sides of the lower end face of the frame 205. A first support frame 207 is fixedly connected inside the mounting bracket 1 at the lower end of the two guide rails 206. Electric telescopic rods 208 are fixedly connected to the center of the rear end face of the two guide rails 206. The output ends of the two electric telescopic rods 208 pass through the rear end face of the two guide rails 206 and extend into the interior of the two guide rails 206, and their ends are fixedly connected to the rear end face of the frame 205. The telescopic rod 208 pushes the frame 205 forward along the two guide rails 206, which in turn moves the two support rods 203 forward. The two hubs 204 roll on the two tracks 201, causing the equipment to move forward. When it reaches the top of the material tray 307, it stops. At this time, the small belt conveyor 4 is started to transport the sheet metal material on the small belt conveyor 4 forward. During the transport process, the two electric telescopic rods 208 are controlled to retract synchronously, and the sheet metal material falls forward onto the upper surface of the material tray 307. The small belt conveyor 4 returns to the initial position and repeats the operation to stack the cut sheet metal material on the material tray 307. Then, the material tray 307 and the stacked sheet metal material are transported together by a forklift, which significantly improves the production efficiency.

[0034] A second support frame 209 is fixedly connected to the upper surface of the first support frame 207 at the lower end of each of the two electric telescopic poles 208. The two second support frames 209 support the lower part of the outer side wall of the two electric telescopic poles 208, so as to provide support force for the two electric telescopic poles 208 through the two second support frames 209 and improve stability. A fixing plate 202 is fixedly connected to the rear part of the upper surface of the two tracks 201. The two tracks 201 are connected through the fixing plate 202, which increases the stability of the two tracks 201.

[0035] like Figure 1 , 2As shown in Figures 3 and 4, an auxiliary structure 3 is provided at the front of the two tracks 201. The auxiliary structure 3 includes two first pillars 301, which are arranged laterally. Each of the two first pillars 301 has a hydraulic lifting machine 304 at its rear end. Each of the two hydraulic lifting machines 304 has a second pillar 305 at its rear end. A material tray 307 is provided between the two hydraulic lifting machines 304. Grooves 309 are provided on both sides of the lower end of the material tray 307. Guide grooves 310 are provided on the inner side walls of the front and rear sides of the two grooves 309. The two grooves 309 are respectively fitted onto the upper end of the two hydraulic lifting machines 304. The two hydraulic lifting machines 304 are started to lift the material tray 307 upward. After the material is released, the two hydraulic lifting machines 304 are lowered by the thickness of one sheet metal piece. The small belt conveyor 4 returns to the initial position. This operation is repeated to reduce the damage to the sheet metal due to the height when stacking sheet metal.

[0036] Two first pillars 301 are fixedly connected to baffles 302 at the front of their upper surfaces. Rubber pads 303 are fixedly connected to the rear surfaces of the baffles 302. Two second pillars 305 are fixedly connected to connecting posts 306 at the upper center of their front surfaces. The two connecting posts 306 are fixedly connected to the rear surfaces of the first pillars 301. The sheet metal is conveyed forward and impacts the rubber pads 303 before falling onto the upper surface of the material tray 307, reducing the impact force when it falls. The two connecting posts 306 connect the two first pillars 301 and the two second pillars 305. The fixed ends of the two hydraulic jacks 304 are fixedly connected to the first pillars 301 and the second pillars 305 to improve the overall stability.

[0037] Forklift fork slots 308 are provided on both sides of the lower end face of the material tray 307. By inserting the forklift fork into the two forklift fork slots 308, the material tray 307 and the stacked sheet metal are transported together, which significantly improves production efficiency.

[0038] Support legs 5 are fixedly connected at the four opposite corners of the lower end face of the mounting bracket 1 to provide support for the mounting bracket 1.

[0039] Working principle: Before use, the grooves 309 on both sides of the material tray 307 are fitted onto the upper surfaces of the two hydraulic jacks 304. The two hydraulic jacks 304 are started to lift the material tray 307 upwards. After the hydraulic pump starts, hydraulic oil is drawn from the oil tank and converted into high-pressure oil through pressurization. The high-pressure oil is regulated by the control valve group to adjust the flow direction and flow rate, and is transmitted to the hydraulic cylinder through the pipeline. The piston in the hydraulic cylinder moves upwards under the action of the high-pressure oil, pushing the lifting platform or support structure connected to it, thereby lifting the heavy object. When it is necessary to lower, the control valve group changes the direction of oil flow, the oil in the hydraulic cylinder flows back to the oil tank, the piston retracts downwards, and the heavy object falls accordingly. This is a commonly used technical solution in existing hydraulic jacks 304, and will not be elaborated on here.

[0040] In use, the laser-cut material is fed into the large belt conveyor 6. The large belt conveyor 6 is then started. It includes a power system, a transmission system, a load-bearing system, and a support system. The motor in the power system starts to rotate after being powered on. The speed is reduced and the torque is increased by the reducer, which transmits the power to the drive roller. When the drive roller rotates, static friction is generated between its surface and the lower cover layer of the conveyor belt. Since the conveyor belt is taut, the static friction is converted into the traction force of the conveyor belt, which drives the conveyor belt to make a closed loop motion around the drive roller and the redirecting roller. This is a commonly used technical solution in existing belt conveyor technology, and will not be elaborated on further here.

[0041] The sheet metal moving forward falls onto the small belt conveyor 4 after passing through the sensing device 8. At this time, the two electric telescopic rods 208 extend synchronously. One telescopic rod acts as the main controller, and the other follows its movement. The controller coordinates the movement of the two telescopic rods simultaneously. This is an existing technique for controlling the synchronous operation of two electric telescopic rods 208, which will not be elaborated on here. The two electric telescopic rods 208 push the frame 205 forward along the two guide rails 206. Pushing the frame 205 forward, the two support rods 203 move forward. The two hubs 204 roll on the two tracks 201, causing the equipment to move forward and stop when it reaches the top of the material tray 307. At this time, the small belt conveyor 4 is started. The small belt conveyor 4 has the same structure as the large belt conveyor 6. The sheet metal material on the small belt conveyor 4 is conveyed forward. During the conveying process, the two electric telescopic rods 208 are controlled to retract synchronously. The sheet metal material is conveyed forward and hits the rubber pad 303 and falls onto the upper surface of the material tray 307, reducing the impact force generated when falling. Then, the two hydraulic lifting machines 304 are controlled to lower the sheet metal material by the thickness of one sheet metal material. The small belt conveyor 4 returns to the initial position. This operation is repeated to stack the cut sheet metal material on the material tray 307. Then, the material tray 307 and the stacked sheet metal material are transported together by a forklift, which significantly improves the production efficiency.

[0042] The equipment also includes an integrated controller. The integrated controller receives signals from various components through input ports. These signals are processed and used as the basis for control decisions. The integrated controller then uses a control algorithm to process the input signals and generates control outputs according to predetermined rules. Based on the results of the control algorithm, the integrated controller sends signals to the actuators through the output ports. The integrated controller can also coordinate the work of various components, such as adjusting the working order and timing of multiple devices to ensure the efficient operation of the system. Furthermore, the integrated controller continuously monitors the operating status of each component and adjusts the control strategy in a timely manner based on feedback to cope with possible changes or anomalies. This solution is a commonly used technical method in the prior art and will not be elaborated on further here.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
