Description

Technical Field

[0001] The present invention relates to the technical field of logistics transportation, and in particular to a flow diversion device for logistics transportation. Background Art

[0002] Logistics refers to the efficient flow and storage of goods from the place of production to the place of consumption, and involves related activities such as information, transportation, inventory, warehousing, material handling, packaging and order fulfillment. Items need to be sorted before logistics transportation. When sorting items, the stacked items are first placed on the surface of the conveyor belt, and then the stacked items are separated by separation equipment, and the separated items are centered on the conveyor belt. Then the camera is used to identify the logistics information, and the diversion equipment at the rear is controlled to classify different categories of items.

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0021] When sorting items, the stacked items are placed on the surface of the conveyor belt, and then the stacked items are separated by a separation device, and the separated items are centered on the conveyor belt. The camera is then used to identify the logistics information, and the diversion equipment at the rear is controlled to classify items of different categories. However, after the items are separated by the separation device, there are still items stacked on each other. Usually, after the camera identifies them, the still stacked items are thrown out of the conveyor belt, and they need to be picked up and put on the conveyor belt again for re-separation, which reduces work efficiency.

[0022] When using a balance wheel sorter to sort items, the packaging of the items or the things carried by the items fall onto the balance wheel sorter, which may easily cause a balance wheel of the balance wheel sorter to get stuck. Since the balance wheel sorter usually has a power source that drives all the balance wheels thereon to rotate together through belts and pulleys, when a balance wheel gets stuck, friction occurs between the pulley related to the balance wheel and the adjacent belt, causing the belt to be worn. At the same time, the friction between the pulley and the belt increases the workload of the balance wheel sorter, resulting in a decrease in the working efficiency of the balance wheel sorter. At the same time, the stuck balance wheel affects the movement of items on the balance wheel sorter.

[0025] Please refer to Figure 7-Figure 9 A power ring 25 is fixedly connected to the rear of the power shaft 19, and the power ring 25 is rotatably connected to the adjacent friction ring 20. A torsion spring is fixedly connected between the front side of the power ring 25 and the adjacent friction ring 20. A limiting ball 26 is slidably connected to the middle part of the power shaft 19, and a spring is fixedly connected between the limiting ball 26 and the adjacent power shaft 19. A groove that matches the adjacent limiting ball 26 is provided on the passive bevel gear 21, which is used to limit the passive bevel gear 21 so that the passive bevel gear 21 and the adjacent active bevel gear 22 remain in a state of disengagement from the transmission match. An active extrusion block 27 is fixedly connected to the right part of the front side of the friction ring 20, and a passive extrusion block 28 is fixedly connected to the left part of the rear side of the passive bevel gear 21. The passive extrusion block 28 is extruded and matched with the adjacent active extrusion block 27.

[0026] Please refer to Figure 8 and Fig. 9 A one-way wheel 29 is installed at the front part of the mounting shell 17. The one-way wheel 29 is fixedly connected to the front end of the adjacent power shaft 19, so that the power shaft 19 can only rotate counterclockwise (from the front to the rear). A spring is fixedly connected between the one-way wheel 29 and the front side of the adjacent passive bevel gear 21, and the elastic coefficient of the spring adjacent to the limiting ball 26 is greater than the elastic coefficient of the spring between the one-way wheel 29 and the adjacent passive bevel gear 21.

[0027] Please refer to Figure 7 , Figure 8 and Fig.10 A reset frame 30 is connected to the mounting shell 17 in a front-rear limited sliding manner. The reset frame 30 and the adjacent mounting shell 17 are fixedly connected with an elastic rope 31. The elastic rope 31 is used to reset the adjacent reset frame 30. The reset frame 30 is squeezed and matched with the adjacent passive bevel gear 21 to reset the passive bevel gear 21.

[0028] When the device is used to sort items, the first conveyor belt 1, the first motor 3 and the second motor 15 are started, the output shaft of the first motor 3 drives the friction table 4 to rotate, the friction table 4 drives the friction wheel 8 to rotate through friction, the friction wheel 8 drives the roller of the second conveyor belt 2 to rotate through the transmission shaft 7 and the bevel gear set, so that the second conveyor belt 2 starts to run (at this time, the conveying speed of the second conveyor belt 2 is consistent with the conveying speed of the first conveyor belt 1), the items enter the first conveyor belt 1 after passing through the separation device, and move right with the first conveyor belt 1, contact with the second conveyor belt 2 when the items move to the end of the first conveyor belt 1, and continue to move right with the second conveyor belt 2, while the items move with the first conveyor belt 1, the camera above the first conveyor belt 1 determines the state of the items, when the camera observes that there are two items stacked, the camera transmits the information to the control terminal, when the stacked items move between the first conveyor belt 1 and the second conveyor belt 2, the control terminal starts the first electric push rod 5, the telescopic end of the first electric push rod 5 drives the partition plate 6 to move upward, the partition plate 6 pushes the stacked part of the two items upward, so that the two items are separated.

[0029] While the partition plate 6 moves upward, the partition plate 6 drives the friction wheel 8 to move upward through the bracket, and the friction wheel 8 moves upward along the friction table 4, so that the transmission ratio between the two is increased, that is, the rotation speed of the friction wheel 8 is increased, so that the second conveyor belt 2 drives one of the two stacked objects to move right quickly, so that the two objects are separated, and then the control terminal controls the telescopic end of the first electric push rod 5 to reset quickly, and the telescopic end of the first electric push rod 5 drives the partition plate 6 to reset, and the partition plate 6 drives the friction wheel 8 to reset through the bracket, so that the friction wheel 8 and the friction table 4 restore the original transmission ratio, that is, the conveying speeds of the first conveyor belt 1 and the second conveyor belt 2 are consistent.

[0030] After the second motor 15 is started, the output shaft of the second motor 15 drives the adjacent spline shaft 24 to rotate counterclockwise, the spline shaft 24 drives the adjacent connecting shaft 23 to rotate, and at the same time, the spline shaft 24 drives all the spline shafts 24 on the same support frame 9 to rotate counterclockwise together through the pulley and the belt, the connecting shaft 23 drives the adjacent active bevel gear 22 to rotate through the spline, the active bevel gear 22 drives the adjacent power shaft 19 to rotate through the transmission of the adjacent passive bevel gear 21, the power shaft 19 drives the adjacent friction ring 20 to rotate through the adjacent power ring 25 and the torsion spring, the friction ring 20 drives the adjacent roller 18 to rotate through friction, and the friction between the roller 18 and the object is used to transport the object.

[0031] When the items follow the second conveyor belt 2, the barcode scanning device above the second conveyor belt 2 identifies the information of the items, and then the barcode scanning device transmits the information to the control terminal, and the control terminal controls the subsequent equipment (that is, the relevant parts on the three support frames 9) to classify the items (hereinafter, the items need to be placed in the storage box in the left front for example). When the items move to the middle of the second conveyor belt 2, the control terminal starts the first second electric push rod 13 on the left (hereinafter, the relevant parts on the left support frame 9 are used for explanation), the telescopic end of the second electric push rod 13 extends, and the second electric push rod 13 is moved. The telescopic end of the push rod 13 slides along the arc-shaped through hole of the bottom shell 10 through the connecting frame 14 and drives several mounting rings 16 to rotate 45° clockwise. The mounting rings 16 drive the adjacent mounting shells 17 and rollers 18 to rotate together. The rotating rollers 18 are used to guide the items thereon, so that the items make a parabolic motion on the rollers 18. Finally, the items lose contact with the rollers 18 and fall into the storage box in the left front. Then the control terminal controls the extension and retraction of the telescopic end of the second electric push rod 13, and repeats the above steps to change the direction of the rollers 18 and guide the items to a suitable storage box.

[0032] When the roller 18 is transporting items, some items are loosely packed or have gaps in the packaging, causing small items in the items to fall and get stuck in the gap between the roller 18 and the adjacent mounting shell 17, causing the roller 18 to get stuck. After the roller 18 is stuck, the adjacent friction ring 20 stops rotating, and as the power ring 25 continues to rotate, the torsion spring between the power ring 25 and the adjacent friction ring 20 is twisted, and at the same time, the passive bevel gear 21 drives the adjacent passive extrusion block 28 to rotate, and when the passive bevel gear 21 rotates 180° relative to the adjacent friction ring 20, the passive extrusion block 28 contacts the adjacent active extrusion block 27 and squeezes each other. The passive extrusion block 28 drives the adjacent passive bevel gear 21 to move forward and compresses the spring between the passive bevel gear 21 and the adjacent one-way wheel 29. At the same time, the groove on the passive bevel gear 21 gradually corresponds to the adjacent limiting ball 26. The limiting ball 26 enters the groove on the adjacent passive bevel gear 21 under the action of the adjacent spring and limits the adjacent passive bevel gear 21. At this time, the passive bevel gear 21 loses the transmission relationship with the adjacent active bevel gear 22, that is, the passive bevel gear 21 stops rotating. In this way, when one roller 18 is stuck, the power adjacent to the roller 18 is disconnected to prevent the stuck roller 18 from affecting the normal operation of the other rollers 18.

[0033] After the passive bevel gear 21 stops rotating, the friction ring 20 rotates in the opposite direction due to the action of its adjacent torsion spring. The friction ring 20 drives the adjacent roller 18 to rotate in the opposite direction through friction transmission, squeezes out the objects stuck between the roller 18 and the adjacent mounting shell 17, and restores the roller 18 to a free rotation state, reducing the impact on subsequent transportation of objects.

[0034] After the roller 18 rotates in the opposite direction, the worker suspends the sorting of the items (i.e. stops the first conveyor belt 1, the first motor 3 and the second motor 15), and then cleans the roller 18 that has just been stuck. After confirming that the roller 18 can rotate normally, the worker pushes the reset frame 30 adjacent to the stuck roller 18 backwards, so that the reset frame 30 moves backwards and stretches the adjacent elastic rope 31. During the movement of the reset frame 30, the reset frame 30 contacts the front side of the adjacent passive bevel gear 21 and pushes it backwards, and the groove on the passive bevel gear 21 pushes the adjacent The limiting ball 26 is squeezed into the adjacent power shaft 19 again, so that the limiting ball 26 releases the limiting of the adjacent passive bevel gear 21. At this time, the passive bevel gear 21 is reset under the action of the adjacent spring and re-engages with the adjacent active bevel gear 22. Then the worker restarts the first conveyor belt 1, the first motor 3 and the second motor 15, and loosens the reset frame 30, so that the reset frame 30 moves forward and resets under the elastic action of the adjacent elastic rope 31. After the final sorting is completed, the worker stops the first conveyor belt 1, the first motor 3 and the second motor 15.

[0035] It should be noted that: only in this embodiment, the mounting ring 16 and the adjacent mounting shell 17 are set in a fixed connection relationship, and the connecting shaft 23 and the adjacent spline shaft 24 are set in a fixed connection relationship. In subsequent embodiments, the mounting ring 16 and the adjacent mounting shell 17 are splined, and the connecting shaft 23 and the adjacent spline shaft 24 are splined.

[0036] When using a balance wheel sorting machine to sort some large-mass, small-volume items, due to the large inertia of such items and the small number of balance wheels they contact, that is, the small total contact area between the items and the balance wheel, it is easy for relative displacement to occur between the items and the balance wheel, resulting in a reduction in the guiding effect of the balance wheel on the moving path of the items, making it impossible for the items to move to the designated position in the end.

[0037] Example 2: Based on Example 1, please refer to Figure 6 , Figure 7 , Fig.10 and Fig.11 , and also includes equidistant and evenly distributed limit members 32, the limit members 32 are fixedly connected to the adjacent mounting plate 11 near the adjacent mounting ring 16, and a first guide groove 33 and a second guide groove 34 are provided in the middle of the left side of the mounting shell 17, and the central angles corresponding to the projections of the first guide groove 33 and the second guide groove 34 in the horizontal direction are both 45°, and the lower end of the first guide groove 33 is connected to the lower end of the adjacent second guide groove 34. The limit member 32 slides in the adjacent first guide groove 33 and the adjacent second guide groove 34, the mounting ring 16 is spline-connected to the adjacent mounting shell 17, and the connecting shaft 23 is spline-connected to the adjacent spline shaft 24. In the leftmost column of mounting shells 17 on the mounting plate 11, the first guide groove 33 The height of the first guide groove 33 and the second guide groove 34 are equal. For the same mounting plate 11 and in the direction from left to right, the heights of the first guide groove 33 and the second guide groove 34 decrease successively, so that after the rollers 18 on the same mounting plate 11 are deflected, the rollers 18 evenly distributed on the two adjacent mounting plates 11 form a step surface to intercept the goods and improve the accuracy of the goods diversion. In the direction from front to back, in the rightmost column of mounting shells 17 on the mounting plate 11, the heights of the first guide groove 33 decrease successively, and at the same time, the heights of the second guide groove 34 increase successively, so that after the rollers 18 on the same mounting plate 11 are deflected, the rollers 18 evenly distributed on the same mounting plate 11 form an inclined surface to guide the movement of the goods.

[0038] Please refer to Figure 4 , Figure 5 and Fig.12 A connecting plate 35 is fixedly connected to the right portion of the upper side of the top shell 12 , and an elastic sheet 36 is fixedly connected to the left side of the connecting plate 35 . The length of the elastic sheet 36 is greater than the length of the connecting plate 35 , and the height of the connecting plate 35 and the elastic sheet 36 is less than the height of the roller 18 .

[0039] Please refer to Fig.12The connecting frame 14 is slidably connected to the left and right positions with a sliding column 37 which is slidably connected to the adjacent top shell 12 front and rear positions. The sliding column 37 is squeezed and matched with the adjacent elastic sheet 36 to change the position where the distance between the adjacent elastic sheet 36 and the adjacent connecting plate 35 is the largest, and to make the elastic sheet 36 form an inclined surface to guide the movement of the object.

[0040] When sorting items (hereinafter, the example of sorting items into the storage box in the left front is still taken as an example, and the relevant parts on the left support frame 9 are used for explanation), the steps of Example 1 are repeated to rotate the mounting ring 16 45° clockwise, and the mounting ring 16 drives the adjacent mounting shell 17 to rotate relative to the adjacent limiting member 32. During the rotation of the mounting shell 17, the limiting member 32 moves along the adjacent first guide groove 33, so that the mounting shell 17 moves downward while rotating. Finally, the height of the plurality of rollers 18 is as follows: the height of the rollers 18 in the left row is equal and slightly lower than the height of the second conveyor belt 2. In the direction from left to right, the height of the rollers 18 decreases successively, and at the same time, the height of the rollers 18 in the rightmost row increases successively in the direction from front to back, and the highest point of the rollers 18 in the rightmost row is lower than the height of the connecting plate 35. In the process of the rollers 18 transporting items, the plurality of rollers 18 are tilted forward as a whole to guide the items to move forward.

[0041] When the telescopic end of the second electric push rod 13 extends out and drives the connecting frame 14 to move, the connecting frame 14 pushes the sliding column 37 to move backward (during this process, the sliding column 37 slides along the connecting frame 14), and the sliding column 37 squeezes the adjacent elastic sheet 36, so that the position where the distance between the elastic sheet 36 and the connecting plate 35 is the largest moves backward. When sorting items with large mass and small volume, the items eventually move to the rightmost side of the plurality of rollers 18 and collide with the front part of the left side of the elastic sheet 36, so that the elastic sheet 36 is deformed and cushions the items. At the same time, the front part of the left side of the elastic sheet 36 is in an inclined state toward the left front, and together with the roller 18, guides the items to move forward, and finally falls into the storage box on the left front side.

[0042] Then, the control terminal controls the telescopic end of the second electric push rod 13 to retract, swings the roller 18 to the initial angle, and repeats the above steps in reverse, so that the mounting ring 16 drives the adjacent mounting shell 17 and the roller 18 to swing and reset, and the limit member 32 slides along the adjacent first guide groove 33 and repeatedly moves to the connection point between the first guide groove 33 and the adjacent second guide groove 34, and the sliding column 37 is driven by the connecting frame 14 to move forward and reset.

[0043] In the subsequent sorting process, if the items need to be sorted into the storage box on the rear side, the control terminal controls the telescopic end of the second electric push rod 13 corresponding to the storage box to retract, and drives the adjacent mounting ring 16, the adjacent mounting shell 17 and the adjacent roller 18 to rotate counterclockwise by 45°. During this process, the limit member 32 slides along the adjacent second guide groove 34, causing the plurality of rollers 18 to tilt backward as a whole, guiding the items to move backward.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
