Description

Technical Field

[0001] This utility model belongs to the technical field of assembly line production and processing equipment, specifically relating to a 180-degree flipping device for turnover baskets. Background Technology

[0002] Turnover baskets are divided into non-mesh turnover boxes and mesh turnover baskets. They are widely used in industrial assembly lines and warehousing, and together with turnover boxes and plastic pallets, they form the "three treasures" of industry. Now, turnover baskets are also beginning to be widely used in agricultural development, replacing bamboo baskets for storing fruits and vegetables; they are also suitable for the turnover of parts in warehouses, production lines, and within factories. With the development of the agricultural industry, turnover baskets will play an increasingly important role in the economy.

[0003] Currently, the equipment used to clean turnover baskets on the market usually cleans them upside down. After cleaning, the turnover baskets are still upside down. When loading materials, the turnover baskets need to be manually flipped 180 degrees to be picked up and used. Therefore, this cleaning and use process adds a manual flipping action, which not only affects the work efficiency of the subsequent production line, but also increases the labor intensity of workers. In addition, if a robotic arm is used for electric flipping, it will also have the problem of high cost.

[0004] Therefore, there is an urgent need to design a turnover basket turning device that can replace manual labor, thereby improving work efficiency and saving production costs. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a 180-degree flipping device for turnover baskets. The device is equipped with an adjustment plate and multiple rollers connected in the middle flipping mechanism. By designing the interval between the multiple rollers, the turnover basket can flip 180 degrees by its own weight between the multiple rollers until the basket opening is facing upwards and then output, thereby achieving the purpose of saving labor, reducing production costs, and improving work efficiency.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a 180-degree flipping device for turnover baskets, comprising an upper conveying mechanism, a middle flipping mechanism, and a lower conveying mechanism arranged sequentially for flipping and conveying turnover baskets; the upper conveying mechanism includes an upper support frame, with an upper horizontal conveyor belt fixedly connected to the top of the upper support frame; the lower conveying mechanism includes a lower support frame, with a lower horizontal conveyor belt fixedly connected to the top of the lower support frame, and a middle flipping mechanism correspondingly arranged between the upper and lower horizontal conveyor belts; the middle flipping mechanism includes a middle support frame, with adjusting perforated plates connected vertically on both sides of the middle support frame, the adjusting perforated plates having multiple round holes arranged in a square grid array, and the two adjusting perforated plates being sequentially level along the inclined direction from the upper horizontal conveyor belt to the lower horizontal conveyor belt. The conveyor belt is equipped with a first roller, a second roller, a third roller, a fourth roller, and multiple fifth rollers. The bottom edge length of the conveyor belt is 'a', and its height is 'h', where 'a' > 'h'. The radii of the first, second, third, fourth, and fifth rollers are all R, where 2R = 1 / 6h ~ 1 / 4h. The first roller is positioned below the front end of the upper horizontal conveyor belt, with both its horizontal and vertical distances from the upper surface of the conveyor belt less than 2R. The second roller is 2R ~ 3R horizontally and 4R ~ 5R vertically from the first roller. The third roller is 0.5a ~ 0.75a vertically from the upper surface of the conveyor belt. The fourth roller is 0.75a ~ a horizontally from the upper surface of the conveyor belt. The multiple fifth rollers are evenly distributed along the inclined direction between the fourth roller and the upper surface of the lower horizontal conveyor belt.

[0007] Furthermore, the horizontal distance between the adjusting orifice plates is 1.5a~2a, and the height difference between the upper end face of the upper horizontal conveyor belt and the upper end face of the lower horizontal conveyor belt is a~1.5a.

[0008] Furthermore, both the upper and lower horizontal conveyor belts are composed of multiple rollers connected between the side mounting plates on both sides. The rollers located at both ends and the middle of the conveyor belt in the direction of travel are driven by electric motors, while the remaining rollers are driven rollers.

[0009] Furthermore, three shifting rollers are provided on the lower horizontal conveyor belt near the fifth roller. The shifting rollers are rollers with multiple shifting teeth evenly distributed along the circumference.

[0010] Furthermore, the radius of the roller is smaller than the radius R of the first roller, the second roller, the third roller, the fourth roller, and the fifth roller.

[0011] Furthermore, the axis connecting the first, second, third, fourth, and fifth rollers is a smooth curve, and the horizontal height of the fifth roller closest to the upper end face of the lower horizontal conveyor belt is higher than the height of the upper end face of the horizontal conveyor belt.

[0012] Furthermore, the two ends of the first roller, the second roller, the third roller, the fourth roller, and the plurality of fifth rollers are all fixedly connected to the adjustment hole plates on both sides by bolts.

[0013] Furthermore, the adjusting orifice plate is made of pressed steel plate.

[0014] The beneficial effects of this utility model are:

[0015] 1) The device of this utility model is equipped with an adjustment hole plate and multiple rollers connected in the middle flipping mechanism. By designing the interval distance between the multiple rollers, the turnover basket can be flipped 180 degrees by its own weight between the multiple rollers until the basket opening is facing upward and then output. Compared with manual flipping, it greatly saves manual labor and improves the working efficiency of flipping turnover baskets. Compared with the electric flipping of robotic arms, it saves production costs and the flipping process is safer.

[0016] 2) The structural design of the adjusting plate in this utility model device can meet the flipping requirements of turnover baskets of different sizes. It can determine the installation positions of the first roller, the second roller, the third roller, the fourth roller and multiple fifth rollers according to the actual size of the turnover basket. Moreover, the position of the rollers can be changed at any time by disassembling the mounting bolts, so that the turnover basket can flip more smoothly on the smooth curve formed between the first roller, the second roller, the third roller, the fourth roller and multiple fifth rollers. On the basis of improving work efficiency, the device is more widely used and practical.

[0017] 3) In this utility model device, three rollers are provided on the lower horizontal transmission belt. The design of the rollers enables the turnover basket near the lower horizontal transmission belt to transition more smoothly from the inclined movement state to the horizontal movement state, avoiding movement failure caused by the corner jamming of the turnover basket in the inclined state, speeding up the transmission of the turnover basket after flipping, and improving work efficiency.

Detailed Implementation

[0022] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0023] Example: Figure 1 and Figure 2 As shown, this utility model provides a 180-degree flipping device for turnover baskets, including an upper conveying mechanism, a middle flipping mechanism, and a lower conveying mechanism arranged sequentially for flipping and conveying turnover baskets 1; the upper conveying mechanism includes an upper support frame 2, and an upper horizontal conveyor belt 5 is fixedly connected to the top of the upper support frame 2; the lower conveying mechanism includes a lower support frame 4, and a lower horizontal conveyor belt 6 is fixedly connected to the top of the lower support frame 4, and the middle flipping mechanism is installed between the upper horizontal conveyor belt 5 and the lower horizontal conveyor belt 6.

[0024] Both the upper horizontal conveyor belt 5 and the lower horizontal conveyor belt 6 are composed of multiple rollers 13 connected between the side mounting plates 14 on both sides. The rollers 13 located at both ends and the middle of the conveyor belt in the direction of travel are driven by electric motors, while the other rollers 13 are driven rollers. Three pawl rollers 15 are installed on the lower horizontal conveyor belt 6 near the fifth roller 12. The pawl rollers 15 are rollers 13 with multiple pawl teeth evenly distributed along the circumference.

[0025] The central tilting mechanism includes a central support frame 3. Adjustment plates 7 are vertically connected to the upper sides of both sides of the central support frame 3. The adjustment plates 7 have multiple circular holes arranged in a grid pattern and are made of pressed steel plates. Between the two adjustment plates 7, a first roller 8, a second roller 9, a third roller 10, a fourth roller 11, and multiple fifth rollers 12 are sequentially and parallelly installed along the inclined direction from the upper horizontal conveyor belt 5 to the lower horizontal conveyor belt 6, and are fixedly connected to the adjustment plates 7 on both sides by bolts. The axis connecting the first roller 8, second roller 9, third roller 10, fourth roller 11, and fifth roller 12 is a smooth curve. The multiple fifth rollers 12 are evenly arranged along the inclined direction between the fourth roller 11 and the upper surface of the lower horizontal conveyor belt 6, and the horizontal height of the fifth roller 12 closest to the upper surface of the lower horizontal conveyor belt 6 is higher than the height of the upper surface of the horizontal conveyor belt 6.

[0026] like Figure 3As shown, let the bottom edge length of the turnover basket 1 be a, and its height be h, where a > h. The radii of the first roller 8, the second roller 9, the third roller 10, the fourth roller 11, and the fifth roller 12 are all R, where 2R = 1 / 6h to 1 / 4h, specifically 2R = 1 / 5h. The first roller 8 is installed near the front end of the upper horizontal conveyor belt 5, and its horizontal and vertical distances from the upper surface of the horizontal conveyor belt 5 are both less than 2R, specifically 4 / 3R. The horizontal distance between the second roller 9 and the first roller 8 is 2R to 3R. The vertical distance is 4R~5R, specifically set to 2R and 4R; the vertical distance between the third roller 10 and the upper surface of the horizontal conveyor belt 5 is 0.5a~0.75a, specifically set to 0.5a; the horizontal distance between the fourth roller 11 and the upper surface of the horizontal conveyor belt 5 is 0.75a~a, specifically set to 0.75a; the horizontal distance between the adjusting orifice plate 7 and the horizontal distance between the upper surface of the upper horizontal conveyor belt 5 and the upper surface of the lower horizontal conveyor belt 6 is a~1.5a, specifically set to 1.2a.

[0027] The radius of roller 13 is smaller than the radius R of the first roller 8, the second roller 9, the third roller 10, the fourth roller 11 and the fifth roller 12.

[0028] Work process:

[0029] The upper horizontal conveyor belt 5 transports the inverted turnover basket 1 to the middle flipping mechanism. When the front end of the turnover basket 1 is lifted off during the conveying process, the frame edge located at the lower front end rotates and falls forward and downward under its own weight. Due to the action of the first roller 8 and the second roller 9, the frame edge of the turnover basket 1 is stuck between the first roller 8 and the second roller 9. Since the distance between the two is insufficient to support the weight of the turnover basket 1, the bottom of the front edge of the turnover basket 1 continues to rotate and fall forward and downward. Under the action of the third roller 10 and the fourth roller 11, the bottom edge of the front end of the turnover basket 1 is stuck between the third roller 10 and the fourth roller 11. Under the limit of the fourth roller 11, the upper part of the turnover basket 1 continues to flip and the basket opening faces upward, and it is located on multiple fifth rollers 12.

[0030] Subsequently, the basket 1 is conveyed forward by the roller 15 on the lower horizontal conveyor belt 6. At this time, the basket 1 is rotated 180 degrees by inertia, thereby realizing the rotation and conveying of the basket 1.

[0031] For turnover baskets of different sizes, the positions of the first roller 8, the second roller 9, the third roller 10, the fourth roller 11 and the fifth roller 12 can be adjusted and fixed on the adjustment hole plate 7 by nuts. The size relationship is adjusted and determined according to the size of the turnover basket, which can adapt to different turnover baskets.

[0032] This utility model device is equipped with an adjustment hole plate and multiple rollers connected in the middle flipping mechanism. By designing the interval distance between the multiple rollers, the turnover basket can be flipped 180 degrees by its own weight between the multiple rollers until the basket opening is facing upwards and then output. Compared with manual flipping, it greatly saves manual labor and improves the working efficiency of flipping turnover baskets. Compared with electric flipping by a robotic arm, it saves production costs and the flipping process is safer.

[0033] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
