Description

Technical Field

[0001] This utility model relates to a tray-setting device, and more particularly to an automatic tray-setting device. Background Technology

[0002] I-beam reels, especially those used for winding steel wire coils, are relatively heavy. After inspection, the finished I-beam reels also need to be stacked, otherwise it would waste space. For loose I-beam reels, most companies usually use robotic arms to grab and stack them one by one, which cannot achieve an automated process and is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] To address the difficulties in steering finished I-beam wheels and the challenges of arranging inspected I-beam wheels into blocks for easy one-time grabbing and stacking, this utility model provides an automatic tray-stacking device and method to solve the aforementioned problems.

[0004] This utility model relates to an automatic tray-stacking device, comprising an X-axis conveyor and a Y-axis conveyor perpendicular to the conveying direction. The X-axis conveyor has M rows of first stations, each equipped with a reversing conveyor section. The Y-axis conveyor has N rows of conveyor sections, each with M rows of second stations. A positioning plate is provided at the end of the Y-axis conveyor away from the X-axis conveyor. The Y-axis conveyor includes a first conveying section, the starting end of which is located on one side of the X-axis conveyor. The first conveying section includes two first driving wheels, a first driven shaft group, and two first power units. The first driven shaft group includes several first driven shafts, one of which is located at the starting end of the first conveying section. The two first power units are respectively located at the first driving wheels. At both ends of the drive shaft, the output end of each first power device is fixedly connected to the corresponding first drive wheel. At both ends of each first driven shaft, there is a first driven wheel. Each first drive wheel is connected to the corresponding first driven wheel via a first chain drive. Each reversing conveyor includes two transition plates, two track plates, and two synchronous wheels. The two synchronous wheels are mounted on the first driven shaft near the beginning of the first conveyor and rotate coaxially with the first driven wheel on the first driven shaft. Each transition plate is hinged to the first driven shaft via a bearing. Each track plate is fixedly connected to the corresponding transition plate. Each synchronous wheel is connected to the corresponding track plate via a second chain drive. The X-axis conveyor is provided with a groove into which the reversing conveyor can be inserted. A lifting device is fixed below the reversing conveyor.

[0005] Furthermore, specifically, the X-axis conveyor has three first workstations, and the Y-axis conveyor has four conveying sections.

[0006] Furthermore, specifically, a first positioning mechanism is provided between each two adjacent first workstations. The first positioning mechanism includes a first stop bar and a first pushing device located below the first stop bar. A first positioning sensor switch is also provided next to each first workstation.

[0007] Furthermore, specifically, a second positioning mechanism is provided between two adjacent second workstations in the Y direction on the Y-axis conveyor. The second positioning mechanism includes a second stop bar and a second pushing device located below the second stop bar. A second positioning induction switch is provided next to each row of conveyors.

[0008] To ensure a more stable operation of the track slab supporting the I-beams, the lifting device consists of two cylinders, each with a Y-interface connected to its extended end. Each cylinder is connected to the corresponding track slab via the Y-interface.

[0009] The conveying method of the automatic tray-stacking device

[0010] a. The I-beams that pass the cord residual torsion test sequentially enter the X-direction conveyor. When the first I-beam reaches the end point of the X-direction conveyor, the first positioning sensor switch next to it senses the first I-beam, and the reversing conveyor section below the first I-beam rises to lift it up. At the same time, the first positioning mechanism next to the first I-beam rises to block and limit the first I-beam. When the second and third I-beams arrive, this process continues until the first row of I-beams is formed.

[0011] b. When all the first row of I-beams are in position, the first positioning mechanism lowers simultaneously, and the reversing conveyor and the Y-axis conveyor begin operation. When the first row of I-beams reaches the row closest to the positioning plate on the Y-axis conveyor, the adjacent second positioning sensor detects the first row of I-beams, and both the reversing conveyor and the N-row conveyor stop operating. The second positioning mechanism rises to limit the movement of the first row of I-beams, and simultaneously, the reversing conveyor lowers.

[0012] Repeat step 'a'. When all the second row of I-beams are in position, the first positioning mechanism lowers simultaneously. Except for the conveyor section below the first row of I-beams, which remains inactive, the reversing conveyor section and the other Y-direction conveyor sections continue operating. When the second row of I-beams reaches the first row, the adjacent second positioning sensor detects it, and the reversing conveyor section and the N-direction conveyor section stop operating. The second positioning mechanism rises to limit the movement of the second row of I-beams, and simultaneously, the reversing conveyor section lowers. This process continues in this manner.

[0013] c. Once the second station of column M on the Y-axis conveyor is fully loaded with I-beams, the gantry robot grabs and stacks them into boxes in one go.

[0014] The advantages of this utility model automatic tray-stacking device are: (1) The finished I-beams are reversed and conveyed under the action of the reversing conveyor, without the need for manual intervention, and the reversing work of the finished I-beams is realized efficiently, saving time, effort and safety; (2) The finished I-beams in four rows and three columns are neatly arranged together in one go, and the robotic arm is used to take away and stack the twelve finished I-beams at one time. The degree of automation is high, the efficiency is high, the grasping is more accurate, and the finished I-beams are stacked more neatly. Attached Figure Description

A positioning plate 4 is provided at the end of the Y-direction conveyor 2 away from the X-direction conveyor 1 in the conveying direction. The Y-direction conveyor 2 includes a first conveying section 5. Of course, the Y-direction conveyor 2 also includes a second conveying section 6, a third conveying section 7, and even more, but the principle is basically the same and the technology is also very conventional, so it will not be described in detail here. Only the first conveying section 5 needs to drive the reversing conveyor section 3 at the same time, so it will be described in detail. The conveying start end of the first conveying section 5 is located on one side of the X-direction conveyor 1. The first conveying section 5 includes two first driving wheels 8, a first driven shaft group, and two first power devices 9. The first driven shaft group includes several first driven shafts 10. The first driven shaft group of this application includes three first driven shafts 10, one of which is... A first driven shaft 10 is located at the beginning of the conveying of the first conveying section 5. Two first power devices 9 are respectively located at both ends of the first driven shaft 10. The output end of each first power device 9 is fixedly connected to the corresponding first driving wheel 8. Each end of the first driven shaft 10 is provided with a first driven wheel 11. Each first driving wheel 8 is connected to the corresponding first driven wheel 11 through a first chain drive. Each reversing conveying section 3 includes two transition plates, two track plates 12 and two synchronous wheels 13. The two synchronous wheels 13 are installed on the first driven shaft 10 near the beginning of the conveying of the first conveying section 5 and rotate coaxially with the first driven wheel 11 on the first driven shaft 10. Each transition plate is hinged to the first driven shaft 10 through a bearing. Each track plate 12 is fixedly connected to the corresponding transition plate. Each synchronous wheel 13 is connected to the corresponding track plate 12 through a second chain drive. The X-direction conveyor 1 is provided with a groove into which the reversing conveying section 3 can be inserted. A lifting device 14 is fixed below the reversing conveying section 3.

[0021] X-axis conveyor 1 has three first workstations, and Y-axis conveyor 2 has four conveyor sections.

[0022] A first positioning mechanism is provided between each pair of adjacent first workstations.

[0025] The conveying method of the automatic tray-stacking device

[0026] a. The I-beams that pass the cord residual torsion test sequentially enter the X-direction conveyor 1. When the first I-beam reaches the end point of the X-direction conveyor 1, the first positioning sensor switch 17 next to it senses the first I-beam, and the reversing conveyor section 3 below the first I-beam will rise to lift the first I-beam. At the same time, the first positioning mechanism next to the first I-beam will rise to block and limit the first I-beam. When the second and third I-beams are in place, and so on, the first row of I-beams is finally formed.

[0027] b. When all the first row of I-beams are in position, the first positioning mechanism lowers simultaneously, and the reversing conveyor 3 and the Y-axis conveyor 2 begin operation. When the first row of I-beams reaches the row on the Y-axis conveyor 2 closest to the positioning plate 4, the adjacent second positioning sensor switch 20 senses the first row of I-beams, and the reversing conveyor 3 and the N-row conveyor units completely stop operating. The second positioning mechanism rises to limit the movement of the first row of I-beams, and simultaneously, the reversing conveyor 3 lowers.

[0028] Repeat step 'a'. When all the second row of I-beams are in position, the first positioning mechanism lowers simultaneously. Except for the conveyor section below the first row of I-beams, which remains inactive, the reversing conveyor section 3 and the other Y-direction conveyor sections continue operating. When the second row of I-beams reaches the first row, the adjacent second positioning sensor switch 20 detects the second row, causing the reversing conveyor section 3 and the N-direction conveyor sections to stop operating. The second positioning mechanism rises to limit the movement of the second row of I-beams, and simultaneously, the reversing conveyor section lowers. This process continues in this manner.

[0029] c. Once the second station of column M on Y-axis conveyor 2 is fully loaded with I-beams, the gantry robot grabs and stacks them into boxes in one go.

[0030] It should be noted that the object placed here can be an I-beam wheel, but is not limited to I-beam wheels. Other shapes of objects can also be automatically arranged in this way as needed, and should also be within the scope of protection of this application.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
