Description

Technical Field

[0001] This utility model belongs to the field of cargo transportation technology and relates to a steering structure for a transport line for bagged goods. Background Technology

[0002] Conveyor lines are an important component of production lines. Rollers are widely used in conveyor lines, and because the main materials for making rollers are carbon steel, stainless steel, and aluminum, roller conveyor lines can generally transport relatively heavy goods. In roller conveyor lines, unidirectional transport often has limitations, and sometimes it is necessary to change the direction of transport. This requires a steering structure to achieve multidirectional flow of goods.

[0003] To this end, Chinese patent application (application number: 202222514717.0) discloses a right-angle turning roller conveyor, including rollers, which are mounted on an L-shaped side plate via rotating shafts, and are driven by a drive motor. Each roller includes several first rollers, several second rollers, and several connecting blocks. The number of first rollers and second rollers is the same, and the other ends of each first roller and its corresponding second roller are perpendicular to each other and connected to the connecting blocks via rotating shafts. The several first rollers and several second rollers are each driven by two sets of drive motors. The several first rollers are arranged vertically side-by-side, and the several second rollers are arranged horizontally parallel. An inclined support is provided between the several first rollers and several second rollers. One end of each of the several first rollers and several second rollers is connected to the L-shaped side plate via rotating shafts, and the other ends of the several first rollers and several second rollers are perpendicular to each other and connected to the inclined support via rotating shafts, forming a right angle. Several steering wheels are provided on the included angle of the L-shaped side plate, and these steering wheels are used to assist in the turning of items.

[0004] However, the above method has the following drawbacks: 1. If the goods are stacked bagged goods, when the goods enter the corner from the second roller, at the turn, the outer side of the lower bag contacts the arc-shaped deflector cylinder and is subjected to lateral pressure pointing inward, causing it to turn along the deflector cylinder. Meanwhile, the upper bag, due to inertia, maintains its original straight-line motion. At this point, the upper bag may slide outward relative to the lower bag, leading to problems such as a shift in the center of gravity and tipping over, resulting in poor transport stability. 2. At the turn, the first roller is connected to the corresponding second roller via a connecting block, and the two are perpendicular to each other. When the goods pass through the turn, the first and second rollers need to rotate synchronously. However, because they are perpendicular, the connecting block is subjected to torsional forces in different directions, which easily causes wear, thus affecting transport stability. 3. Goods can only enter the corner from the first roller and then the second roller according to a predetermined trajectory. That is, goods can only enter subsequent processes from a fixed transport path, resulting in poor flexibility and low transport efficiency. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a steering structure for a transport line for bagged goods. The technical problem this invention aims to solve is: how to ensure transport stability and improve transport efficiency.

[0006] The purpose of this utility model can be achieved through the following technical solution: A turning structure for a transport line for bagged goods, comprising an L-shaped workbench, characterized in that the workbench comprises a vertically connected input section and an output section, a turntable is provided at both ends of the input section, and a plurality of directional rollers are provided parallel to each other along the length direction on the input section and the output section, and a plurality of parallel rotatable rollers are provided on the turntable, and the turntable can rotate and drive the rotatable rollers to be parallel or staggered with their adjacent directional rollers.

[0007] The turntable allows for flexible control of the rotatable rollers, enabling the receiving of goods from the previous process. When the rotatable rollers are parallel to their adjacent directional rollers, goods can be transported smoothly between these parallel rollers. When goods reach the top of the turntable, the turntable rotates the rotatable rollers mounted on it, causing the goods to rotate synchronously. This ensures that stacked bagged goods turn smoothly as a whole, preventing tipping due to lateral pressure and ensuring high transport stability. The turntable rotates independently, and there is no rigid connection between the rotatable rollers above the turntable and their adjacent directional rollers. This avoids the torsional stress concentration at rigid connections during turntable rotation, which could lead to wear and compromise transport stability. The turntables are located at both ends of the input section, that is, at the corner of the workbench and at one end of the workbench. The two turntables can independently receive goods from the previous process. Goods received by the turntable at the corner of the workbench do not need to be rotated and can directly enter the next process. Goods received by the turntable at one end of the workbench enter the next process after passing through the rotation directions of the two turntables in sequence. There are two transportation paths to choose from, which is highly flexible and efficient.

[0008] In the aforementioned steering structure for bagged goods, the length of the directional roller is the same as the length of the rotatable roller. A uniform roller length simplifies manufacturing, assembly, and maintenance processes, reducing spare parts costs. Furthermore, it avoids the situation where mixing roller lengths leads to greater stress on longer rollers due to their longer lever arms and larger torques, thus preventing them from wearing out more easily compared to shorter rollers. This ensures even wear, avoiding localized wear that could affect transport stability.

[0009] In the aforementioned steering structure for bagged goods, the upper surface of the turntable is flush with the upper surface of the worktable. This flush alignment means the rotating roller and the directional roller are at the same height. Whether the goods are moving straight or turning, the entire process is completed on the same plane, helping to prevent swaying, tilting, or even tipping of the goods due to changes in height during transport, thus ensuring transportation stability.

[0010] The aforementioned steering structure for bagged goods features a fixed-direction directional roller and a rotatable roller that can rotate with the turntable to be parallel or perpendicular to adjacent directional rollers. The fixed direction of the directional rollers ensures stable and reliable straight-line transport of goods, while the rotatable rollers' ability to adjust their direction with the turntable allows for flexible steering of goods, effectively balancing transport stability and flexibility, thereby guaranteeing transport efficiency.

[0011] The aforementioned steering structure for bagged goods features a cylindrical turntable. The cylindrical shape of the turntable ensures even force distribution during rotation, contributing to smooth and stable rotation, reducing the likelihood of jamming or malfunctions, and thus promoting stable and efficient transportation.

[0012] Compared with existing technologies, the steering structure for bagged goods has the following advantages:

[0013] 1. In the steering structure used for bagged goods, when the goods are transported to the top of the turntable, the turntable can drive the rotatable rollers on it to rotate together. At this time, the goods rotate synchronously, and the stacked bagged goods are turned smoothly as a whole, without being overturned due to unstable center of gravity caused by lateral squeezing force, thus achieving high transportation stability.

[0014] 2. In the steering structure used for bagged goods, the turntable rotates independently, and there is no rigid connection between the rotatable roller above the turntable and its adjacent directional roller. This avoids the situation where torsional stress is concentrated at the rigid connection when the turntable rotates, which would cause wear and affect the stability of transportation.

[0015] 3. In the steering structure used for bagged goods, the turntables are located at both ends of the input section, that is, the two turntables are located at the corner of the workbench and one end of the workbench, respectively. The two turntables can independently receive goods from the previous process. The goods received by the turntable at the corner of the workbench do not need to be rotated and can directly enter the next process. The goods received by the turntable at one end of the workbench enter the next process after passing through the rotation directions of the two turntables in sequence. There are two transportation paths to choose from, which is highly flexible and efficient. Attached Figure Description

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As can be seen, the steering structure for bagged goods includes an L-shaped worktable 1. The worktable 1 includes a vertically connected input section 1a and an output section 1b. Turntables 1a1 are respectively provided at both ends of the input section 1a. A plurality of directional rollers 2 are arranged parallel to each other along the length direction on both the input section 1a and the output section 1b. A plurality of parallel rotatable rollers 3 are provided on the turntables 1a1. The lengths of the directional rollers 2 and the rotatable rollers 3 are the same. Uniform roller lengths simplify the manufacturing, assembly, and maintenance processes, and reduce spare parts costs. Furthermore, it avoids the situation where mixed roller lengths lead to greater stress on longer rollers due to their longer lever arms and larger torques, thus making them more prone to wear compared to shorter rollers. This ensures even wear and avoids localized wear, which could affect transport stability.

[0022] The upper surface of the turntable 1a1 is flush with the upper surface of the worktable 1. The direction of the directional roller 2 is fixed, while the rotatable roller 3 can rotate with the turntable 1a1 and be parallel or offset from the adjacent directional roller 2. Specifically, the rotatable roller 3 can be parallel or perpendicular to the adjacent directional roller 2. Since the upper surface of the turntable 1a1 is flush with the upper surface of the worktable 1, the rotatable roller 3 and the directional roller 2 are at the same height. Whether the goods move straight or turn, the transport is completed on the same plane, which helps to prevent the goods from swaying, tilting, or even tipping over due to changes in height during transport, thus ensuring the stability of the transport. The fixed direction of the directional roller 2 enables stable and reliable straight-line transport of goods, while the rotatable roller 3 can adjust its direction with the turntable 1a1, allowing for flexible turning of goods. This effectively balances the stability and flexibility of transport, thereby ensuring transport efficiency.

[0023] Turntable 1a1 is cylindrical. The cylindrical shape of turntable 1a1 ensures that the force is evenly distributed during rotation, which helps to achieve smooth and stable rotation, reduces the likelihood of jamming or malfunction, and thus contributes to stable and efficient transportation.

[0024] In actual operation, the turntable 1a1 flexibly controls the direction of the rotatable roller 3. When the rotatable roller 3 is parallel to its adjacent directional roller 2, the goods can be transported smoothly between the adjacent parallel rotatable roller 3 and directional roller 2.

[0025] Two turntables 1a1 are respectively located at both ends of the input section 1a, that is, the two turntables 1a1 are located at the corner and one end of the workbench 1 respectively. There are two transport routes for the goods.

[0026] In the first transport route, the turntable 1a1 at one end of the workbench 1 rotates towards the output port of the previous process. At this time, the rotatable roller 3 on the turntable 1a1 is perpendicular to the directional roller 2 on the adjacent input section 1a. After successfully receiving the goods from the previous process, the turntable 1a1 rotates with the goods, making the upper rotatable roller 3 parallel to the directional roller 2 on the adjacent input section 1a, allowing the goods to be smoothly transported into the directional roller 2 on the input section 1a. Then, the turntable 1a1 at the corner of the workbench 1 rotates, making its upper rotatable roller 3 parallel to the directional roller 2 on the input section 1a, thus receiving the goods from the directional roller 2 on the input section 1a. Next, the turntable 1a1 rotates again with the goods, making its upper rotatable roller 3 parallel to the directional roller 2 on the output section 1b, allowing the goods to be smoothly transported into the directional roller 2 on the output end 1b, and then into the next process.

[0027] In the second transport route, the turntable 1a1 at the corner of the workbench 1 turns towards the output port of the previous process. At this time, the rotatable roller 3 above the turntable 1a1 is parallel to the directional roller 2 on the output section 1b, and the goods successfully received from the previous process can directly enter the next process.

[0028] When goods are transported to the top of turntable 1a1, the turntable 1a1 drives the rotatable roller 3 mounted on it to rotate together. At this time, the goods rotate synchronously, and the stacked bagged goods turn smoothly as a whole, without tipping over due to instability caused by lateral compression. The transportation stability is high. Turntable 1a1 rotates independently, and there is no rigid connection between the rotatable roller 3 above turntable 1a1 and its adjacent directional roller 2. This avoids the situation where torsional stress is concentrated at the rigid connection point during the rotation of turntable 1a1, causing wear and affecting transportation stability. The two turntables 1a1 can simultaneously and independently receive goods from the previous process. Goods received by the turntable 1a1 at the corner of workbench 1 do not need to be rotated and can directly enter the next process. Goods received by the turntable 1a1 at one end of workbench 1 enter the next process after passing through the rotation directions of the two turntables 1a1 in sequence. There are two transportation paths to choose from, which is highly flexible and efficient.
