Abstract
Description
Technical Field
[0001] This invention relates to a roller ramp buffer line, and more particularly to a roller ramp buffer line that can effectively control the downward speed of the material box. Background Technology
[0002] Turnover bins are a primary method for storing products in companies producing small and medium-sized items. They can be categorized, stacked, and used for transporting and storing goods. With the continuous improvement of production capacity and the increasing functionality of automated conveyor lines for turnover bins, these lines have taken on the task of connecting various process stages. Different types of conveyors transport turnover bins to designated manual operation stations. The picking station is a crucial link in the entire bin turnover process; it requires picking and matching different materials and then transporting the picked and matched bins to the next station. Therefore, the conveyor line at the front end of the picking station... Typically, a sloping buffer line is installed to accumulate turnover boxes that need to be picked. Existing sloping buffer lines generally use unpowered sliding rollers to accumulate multiple boxes. When the weights of the boxes being accumulated are similar, this structure can effectively achieve the function of buffering and accumulating. However, when the turnover boxes are large in weight and volume, due to the inertia of the boxes themselves, the sliding speed of the boxes cannot be controlled, resulting in damage to the boxes after impact. How to achieve smooth sliding and dense stacking of boxes of different weights on the picking buffer line has become an urgent problem that sorting stations need to solve. Summary of the Invention
[0003] This invention provides a roller ramp buffer line that can effectively control the downward speed of the hopper, solving the technical problem of how to achieve smooth downward movement and dense sorting and accumulation of hoppers of different weights on the picking buffer line.
[0004] The present invention solves the above technical problems through the following technical solutions: A ramp roller buffer line with effectively adjustable material bin sliding speed includes a picking station, a first accumulation turnover bin, and a second accumulation turnover bin. A buffer accumulation line support is provided on the right side of the picking station. On the buffer accumulation line support, a first unpowered roller support track, a second unpowered roller support track, and a third unpowered roller support track are sequentially connected from left to right. A first row of unpowered rollers is evenly spaced on the first unpowered roller support track, a second row of unpowered rollers is evenly spaced on the second unpowered roller support track, and a third row of unpowered rollers is evenly spaced on the third unpowered roller support track. A first row of unpowered rollers, a second row of unpowered rollers, and a third row of unpowered rollers are arranged on a first inclined surface. A material box accumulation blocking step is provided between the picking station and the support track of the first unpowered roller. A first powered lifting roller is arranged between the support track of the first unpowered roller and the support track of the second unpowered roller. A second powered lifting roller is arranged between the support track of the second unpowered roller and the support track of the third unpowered roller. A third powered lifting roller is arranged on the right side of the support track of the third unpowered roller. The first, second, and third powered lifting rollers are arranged on a second inclined surface, which is higher than the first inclined surface.
[0005] A first lifting roller drive sprocket is located at the front end of the first powered lifting roller, a second lifting roller drive sprocket is located at the front end of the second powered lifting roller, and a third lifting roller drive sprocket is located at the front end of the third powered lifting roller. A first set of three rows of transmission sprockets is located on the buffer accumulation line support below the first lifting roller drive sprocket, a second set of three rows of transmission sprockets is located on the buffer accumulation line support below the second lifting roller drive sprocket, and a third set of three rows of transmission sprockets is located on the buffer accumulation line support below the third lifting roller drive sprocket. The third set of three rows of transmission sprockets... The shaft is connected to the output shaft of the drive motor. A third vertical annular transmission chain is provided between the third group of three-row transmission sprockets and the third lifting roller drive sprocket. A second vertical annular transmission chain is provided between the second group of three-row transmission sprockets and the second lifting roller drive sprocket. A first vertical annular transmission chain is provided between the first group of three-row transmission sprockets and the first lifting roller drive sprocket. A first transverse annular chain is provided between the first group of three-row transmission sprockets and the second group of three-row transmission sprockets. A second transverse annular chain is provided between the second group of three-row transmission sprockets and the third group of three-row transmission sprockets.
[0006] A support pad is fixedly connected to the bottom surface of the first accumulation turnover box. The area of the support pad is smaller than the area of the bottom surface of the first accumulation turnover box. A rectangular annular step is provided between the support pad and the bottom surface of the first accumulation turnover box. After the first accumulation turnover box and the second accumulation turnover box are in place, a first power lifting roller is positioned between the rear end of the rectangular annular step on the bottom surface of the first accumulation turnover box and the front end of the rectangular annular step on the bottom surface of the second accumulation turnover box. The first power lifting roller does not contact the first accumulation turnover box and the second accumulation turnover box.
[0007] A method for effectively controlling the sliding speed of the material box on an inclined roller buffer line. The first step involves the first accumulation and turnover bin being conveyed onto the unpowered rollers of the buffer accumulation line support, where it slides tilted to the left from right to left. The second step is that when the left front end of the first accumulation turnover box slides to the position of the third power lifting roller, due to the effect of the inclined downward force, the bottom surface of the front end of the first accumulation turnover box is lifted and enters the upper part of the third power lifting roller. By controlling the rotation speed of the third power lifting roller, the inclined downward speed of the first accumulation turnover box can be controlled. Third step: The first accumulation turnover box continues to slide downward under the control of the third power lifting roller. When the right rear end of the first accumulation turnover box is separated from the third power lifting roller, the left front end of the first accumulation turnover box slides to the position of the second power lifting roller. Fourth step: Due to the downward tilting force, the lower left front end of the first accumulation turnover box is lifted and enters the upper part of the second power lifting roller. By controlling the rotation speed of the second power lifting roller, the downward tilting speed of the first accumulation turnover box can be adjusted. Step 5: The first accumulation turnover box continues to slide downward under the control of the second power lifting roller. When the right rear end of the first accumulation turnover box is disengaged from the second power lifting roller, the left front end of the first accumulation turnover box slides to the position of the first power lifting roller. Step 6: Due to the downward tilting force, the lower left front end of the first accumulation turnover box is lifted and enters the area above the first power lifting roller. By controlling the rotation speed of the first power lifting roller, the downward tilting speed of the first accumulation turnover box can be regulated. Step 7: The first accumulation turnover box continues to slide downwards at an angle under the control of the first power lifting roller. When the right rear end of the first accumulation turnover box disengages from the first power lifting roller, the left front end of the first accumulation turnover box slides to the accumulation blocking step of the box, thus realizing accumulation.
[0008] This invention enables the smooth sliding and dense stacking of bins of different weights on the picking buffer line. By controlling the rotation speed of the power lifting roller, the sliding speed of the inclined bins can be controlled, avoiding impact collisions when adjacent bins are stacked in place, and achieving safe and stable operation of the picking station.

Detailed Implementation
[0010] The present invention will now be described in detail with reference to the accompanying drawings: A ramp roller buffer line with effectively adjustable material box sliding speed includes a picking station 1, a first accumulation turnover box 9, and a second accumulation turnover box 27. Multiple accumulation turnover boxes are conveyed into the ramp accumulation line on the right side of the picking station 1 for accumulation, facilitating picking operations by the operators at the picking station 1. A buffer accumulation line support 2 is provided on the right side of the picking station 1. On the buffer accumulation line support 2, a first unpowered roller support track 3, a second unpowered roller support track 5, and a third unpowered roller support track 7 are sequentially connected from left to right. A first row of unpowered rollers 4 is arranged at equal intervals on the first unpowered roller support track 3, a second row of unpowered rollers 6 is arranged at equal intervals on the second unpowered roller support track 5, and a third row of unpowered rollers 8 is arranged at equal intervals on the third unpowered roller support track 7. Powered roller 4, second row of unpowered rollers 6, and third row of unpowered rollers 8 are arranged on the first inclined surface, with the inclination direction being downward from right to left. A material box accumulation blocking step 12 is provided between the picking station 1 and the first unpowered roller support track 3 to prevent the first accumulation turnover box 9 from sliding down into place. A first powered lifting roller 13 is provided between the first unpowered roller support track 3 and the second unpowered roller support track 5. A second powered lifting roller 14 is provided between the second unpowered roller support track 5 and the third unpowered roller support track 7. A third powered lifting roller 15 is provided on the right side of the third unpowered roller support track 7. The first powered lifting roller 13, the second powered lifting roller 14, and the third powered lifting roller 15 are arranged on the second inclined surface, which is slightly higher than the first inclined surface, and the inclination of the two inclined surfaces is the same.
[0011] A first lifting roller drive sprocket 16 is provided at the front end of the first power lifting roller 13, a second lifting roller drive sprocket 17 is provided at the front end of the second power lifting roller 14, and a third lifting roller drive sprocket 18 is provided at the front end of the third power lifting roller 15. A first set of three rows of transmission sprockets 19 are provided on the buffer accumulation line support 2 below the first lifting roller drive sprocket 16, a second set of three rows of transmission sprockets 2 are provided on the buffer accumulation line support 2 below the second lifting roller drive sprocket 17, and a third set of three rows of transmission sprockets 21 are provided on the buffer accumulation line support 2 below the third lifting roller drive sprocket 18. The axle of the third set of three rows of transmission sprockets 21 is connected to the output shaft of the drive motor 28. A third vertical annular transmission chain 26 is provided between the third set of three rows of transmission sprockets 21 and the third lifting roller drive sprocket 18. A second vertical annular transmission chain 24 is provided between the moving sprockets 17; a first vertical annular transmission chain 22 is provided between the first group of three-row transmission sprockets 19 and the first lifting roller drive sprocket 16; a first transverse annular chain 23 is provided between the first group of three-row transmission sprockets 19 and the second group of three-row transmission sprockets 20; and a second transverse annular chain 25 is provided between the second group of three-row transmission sprockets 20 and the third group of three-row transmission sprockets 21. By adjusting the speed of the drive motor 28 and through the above chain transmission mechanism, the speeds of the first power lifting roller 13, the second power lifting roller 14, and the third power lifting roller 15 can be simultaneously adjusted. By controlling the slower speed of the above three power lifting rollers, the downward sliding speed of the first accumulation turnover box 9 can be controlled, so that the first accumulation turnover box 9 is freed from the traditional phenomenon of relying on unpowered rollers to accelerate downwards, and the downward sliding speed of the first accumulation turnover box 9 can be adjusted.
[0012] The bottom of the first accumulation turnover box 9 is designed with a support pad 10 for limiting stacking. The support pad 10 is smaller than the bottom surface of the first accumulation turnover box 9. Thus, a rectangular annular step 11 is formed between the support pad 10 and the bottom surface of the first accumulation turnover box 9. After the first accumulation turnover box 9 and the second accumulation turnover box 27 are stacked in place, the first power lifting roller 13 is positioned between the rear end of the rectangular annular step 11 on the bottom surface of the first accumulation turnover box 9 and the front end of the rectangular annular step 11 on the bottom surface of the second accumulation turnover box 27. Furthermore, the first power lifting roller 13 does not contact the first accumulation turnover box 9 and the second accumulation turnover box 27, so that the continuous rotation of the first power lifting roller 13 will no longer drive the first accumulation turnover box 9 and the second accumulation turnover box 27.
[0013] A method for effectively controlling the downward speed of a material box on a ramp roller buffer line, wherein the ramp roller buffer line includes a buffer accumulation line support 2 set on the right side of the picking station 1. On the buffer accumulation line support 2, a first unpowered roller support track 3, a second unpowered roller support track 5, and a third unpowered roller support track 7 are sequentially connected from left to right. A first row of unpowered rollers 4 are arranged at equal intervals on the first unpowered roller support track 3, a second row of unpowered rollers 6 are arranged at equal intervals on the second unpowered roller support track 5, and a third row of unpowered rollers 8 are arranged at equal intervals on the third unpowered roller support track 7. The first row of unpowered rollers 4 and the second row of unpowered rollers 8... The cylinder 6 and the third row of unpowered rollers 8 are arranged on the first inclined surface; a first powered lifting roller 13 is arranged between the first unpowered roller support track 3 and the second unpowered roller support track 5, a second powered lifting roller 14 is arranged between the second unpowered roller support track 5 and the third unpowered roller support track 7, and a third powered lifting roller 15 is arranged on the right side of the third unpowered roller support track 7; the first powered lifting roller 13, the second powered lifting roller 14, and the third powered lifting roller 15 are arranged on the second inclined surface, which is higher than the first inclined surface; a material box accumulation blocking step 12 is arranged between the picking station 1 and the first unpowered roller support track 3; characterized by the following steps: Step 1: The first accumulation turnover bin 9 is conveyed into the non-powered roller of the buffer accumulation line support 2 and slides tilted to the left in a right-to-left direction; The second step is that when the left front end of the first accumulation turnover box 9 slides to the position of the third power lifting roller 15, due to the effect of the inclined downward force, the bottom surface of the front end of the first accumulation turnover box 9 is lifted and enters the upper part of the third power lifting roller 15. By controlling the rotation speed of the third power lifting roller 15, the inclined downward speed of the first accumulation turnover box 9 can be controlled. Third step: The first accumulation turnover box 9 continues to slide downward under the control of the third power lifting roller 15. When the right rear end of the first accumulation turnover box 9 is disengaged from the third power lifting roller 15, the left front end of the first accumulation turnover box 9 slides to the position of the second power lifting roller 14. Fourth step: Due to the downward tilting force, the lower left front end of the first accumulation turnover box 9 is lifted and enters the upper part of the second power lifting roller 14. By controlling the rotation speed of the second power lifting roller 14, the downward tilting speed of the first accumulation turnover box 9 can be controlled. Step 5: The first accumulation turnover material box 9 continues to slide downward under the control of the second power lifting roller 14. When the right rear end of the first accumulation turnover material box 9 is disengaged from the second power lifting roller 14, the left front end of the first accumulation turnover material box 9 slides to the position of the first power lifting roller 13. Step 6: Due to the downward tilting force, the lower left front end of the first accumulation turnover box 9 is lifted and enters the area above the first power lifting roller 13. By controlling the rotation speed of the first power lifting roller 13, the downward tilting speed of the first accumulation turnover box 9 can be regulated. Step 7: The first accumulation turnover box 9 continues to slide downward under the control of the first power lifting roller 13. When the right rear end of the first accumulation turnover box 9 is disengaged from the first power lifting roller 13, the left front end of the first accumulation turnover box 9 slides to the accumulation blocking step 12 of the box to realize accumulation. The first power lifting roller 13, the second power lifting roller 14, and the third power lifting roller 15 can be powered rollers with their own drive. By controlling their rotation speed, the downward tilting speed of the first accumulation turnover box 9 can be adjusted, so that it can slide smoothly to the accumulation position and avoid impact collision between adjacent boxes.
[0014] A first lifting roller drive sprocket 16 is provided at the front end of the first power lifting roller 13, a second lifting roller drive sprocket 17 is provided at the front end of the second power lifting roller 14, and a third lifting roller drive sprocket 18 is provided at the front end of the third power lifting roller 15. A first set of three rows of transmission sprockets 19 is provided on the buffer accumulation line support 2 below the first lifting roller drive sprocket 16, a second set of three rows of transmission sprockets 20 is provided on the buffer accumulation line support 2 below the second lifting roller drive sprocket 17, and a third set of three rows of transmission sprockets 19 is provided on the buffer accumulation line support 2 below the third lifting roller drive sprocket 18. The third set of three-row drive sprockets 21 has its axle connected to the output shaft of the drive motor 28. A third vertical annular drive chain 26 is provided between the third set of three-row drive sprockets 21 and the third lifting roller drive sprocket 18. A second vertical annular drive chain 24 is provided between the second set of three-row drive sprockets 20 and the second lifting roller drive sprocket 17. A first vertical annular drive chain 22 is provided between the first set of three-row drive sprockets 19 and the first lifting roller drive sprocket 16. A third vertical annular drive chain 26 is provided between the first set of three-row drive sprockets 19 and the second set of three-row drive sprockets 20. A transverse annular chain 23 is provided, and a second transverse annular chain 25 is provided between the second group of three-row drive sprockets 20 and the third group of three-row drive sprockets 21. The three-row drive sprockets consist of three sprockets arranged side by side on the same sprocket shaft, which are integrally formed with the sprocket shaft and rotate synchronously. The drive motor synchronously drives the third lifting roller drive sprocket 18 to rotate via the third vertical annular drive chain 26, thereby regulating the rotation of the third power lifting roller 15 to the designed speed. At the same time, the second sprocket on the third lifting roller drive sprocket 18 drives the second group of three-row drive sprockets 20 and 21 via the second transverse annular chain 25. The first set of three-row drive sprockets 20 rotate synchronously. The second sprocket in the second set of three-row drive sprockets 20 drives the second lifting roller drive sprocket 17 to rotate synchronously through the second vertical annular drive chain 24, thereby driving the second power lifting roller 14 to rotate synchronously. At the same time, the third sprocket in the second set of three-row drive sprockets 20 drives the first set of three-row drive sprockets 19 to rotate through the first horizontal annular chain 23. The second sprocket in the first set of three-row drive sprockets 19 drives the first lifting roller drive sprocket 16 to rotate through the first vertical annular drive chain 22, thereby driving the first power lifting roller 13 to rotate synchronously.
[0015] All of the above-mentioned non-powered rollers are steel rollers; the three powered lifting rollers are rubber-coated powered rollers. The friction between these rubber-coated powered rollers and the support pad 10 fixedly connected to the bottom surface of the first accumulation turnover box 9 is relatively large, so that the downward sliding of the first accumulation turnover box 9 is basically controlled by the rotation of the rubber-coated powered rollers, thus preventing the phenomenon of high-speed sliding.
[0016] When the first accumulation and turnover bin 9 on the automated conveyor line enters the inclined roller buffer line, the support plate 10 on the first accumulation and turnover bin 9 first contacts the unpowered roller at the top of the line and begins to slide down to the lower left. At this time, the drive motor 28 starts, driving three sets of three-row transmission sprockets to rotate synchronously. Each set of three-row transmission sprockets drives the first lifting roller drive sprocket 16, the second lifting roller drive sprocket 17, and the third lifting roller drive sprocket 18 to rotate synchronously, thereby realizing the synchronous rotation of the first powered lifting roller 13, the second powered lifting roller 14, and the third powered lifting roller. 15. The rollers rotate synchronously at the designed rotation speed. The rubber-coated power lifting rollers and the support pads 10 on the first accumulation turnover box 9 are in contact and frictional engagement to control the downward sliding speed of the first accumulation turnover box 9. The rotation speed of the drive motor can be pre-designed according to the volume and weight of the accumulated turnover boxes being transported, so as to achieve scientific control of different boxes. After all the turnover boxes are accumulated, the drive sprockets of each lifting roller are set in the gap between two adjacent boxes, so that each lifting roller is in an unloaded rotation state.
