TECHNICAL FIELD
[0001] The present application relates to the technical field of suspension conveying equipment, in particular to a self-adaptive suspension conveying device for an automatic production line. BACKGROUND
[0002] With the continuous improvement of industrial automation level, the suspension conveying device as a key logistics equipment in modern intelligent manufacturing system is widely used in automobile manufacturing, home appliance production, food processing and other industries. This kind of device effectively utilizes the upper space of the factory building through air conveying mode, realizes the automatic circulation of materials between processes, greatly improves the production efficiency, and optimizes the utilization rate of workshop floor space. The introduction of self-adaptive suspension conveying system enables the production line to flexibly cope with multi-variety and small-batch production requirements, providing important support for modern flexible manufacturing.
[0003] The traditional device has the following disadvantages:
[0004] The current common self-adaptive suspension conveying device is mainly composed of a single guide rail, a suspension conveying vehicle and a driving system. The conveying vehicle suspended below the guide rail is connected with the guide rail through a plurality of roller combinations, part of which is used as a driving wheel to provide forward power, and the rest is used as a bearing wheel. The goods to be transported are carried by a lifting appliance below the conveying vehicle to realize the suspension conveying of the materials. However, the existing technology has obvious defects: the traditional conveying vehicle rollers are arranged horizontally in front and back, and this rigid driving structure is only suitable for horizontal or small slope straight tracks. When the conveying path needs to cross different working areas and there is a height change, the track will have an arc change in the vertical direction. At this time, the traditional conveying vehicle will often have the problem of jamming because the vehicle body cannot be twisted relatively. This limitation seriously restricts the flexibility of the line layout of the suspension conveying system, making it difficult for the system to adapt to complex three-dimensional space path planning requirements. In actual application, it is often necessary to increase the transfer point or use ground conveying to supplement, which increases the system complexity and cost. SUMMARY

[0026] Compared with the prior art, the beneficial effects of the present invention are:
[0027] 1. This invention, by setting up a drive component, changes the original multi-wheel combination drive to a dual-wheel drive with drive rollers and rollers clamping each other up and down. Combined with the support and adjustment mechanism, it stabilizes the vehicle body. When passing through the arc track, it will not get stuck because the vehicle body cannot be relatively twisted. This makes the suspended conveyor device adaptable to the lifting arc track, improves the flexibility of the suspended conveyor system's line layout, and reduces the system's complexity and cost.
[0028] 2. This invention, by incorporating a friction adjustment component, enables flexible adjustment of the friction between the drive roller and the I-beam slide rail. This allows for compensation of friction by rotating the lifting rod when the drive roller wears out, reducing maintenance costs. Alternatively, the drive friction can be precisely set according to the weight requirements of the goods, significantly improving energy utilization and reducing overall energy consumption. Furthermore, if the track has a certain thickness error, the continuous pressure of the compression spring can ensure continuous power output, resulting in a high fault tolerance rate.
[0029] 3. This invention, by setting up a support adjustment mechanism, keeps the extension and retraction of the adjustment rods and pulleys on both sides consistent, so that the machine housing always remains parallel to the I-beam slide rail when moving horizontally. The synchronous retraction and extension of the adjustment rods and pulleys on both sides of the machine housing ensures that the machine housing can smoothly enter and leave the slide rail. At the same time, when the machine housing enters the arc section of the I-beam slide rail, it always remains parallel to the tangent at the contact point between the I-beam slide rail and the drive roller, so that the machine housing is always in the optimal posture during the movement and will not collide. Moreover, the throughput efficiency and passage fault tolerance are the highest under this posture.
[0030] 4. This invention, by incorporating a detection mechanism, enables pre-judgment of different arc shapes before the machine housing enters the bend of the I-beam slide rail. The judgment logic is simple and clear, allowing the controller to accurately issue control commands to adjust the extension and retraction of the adjusting rod and pulley, thereby ensuring the smooth entry and exit of the machine housing from the bend.

[0045] As a further improvement of the present invention, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0046] Please see Figures 1-11As shown, this invention provides a technical solution for an adaptive suspended conveyor device for an automated production line: An adaptive suspended conveyor device for an automated production line includes an I-beam slide rail 1 and a housing 2. The lower end of the housing 2 is fixedly connected to a shelf for suspending or binding goods. A hanging plate 3 is fixedly installed on the upper end of the housing 2, and a crossbeam 4 is fixedly connected to the upper end of the hanging plate 3. The housing 2 is suspended below the I-beam slide rail 1 via the hanging plate 3 and the crossbeam 4. Figure 1 As shown, the crossbeam 4 is inserted into the grooves on both sides of the I-beam slide rail 1 to bear the weight of the entire device and the cargo below. The housing 2 and the crossbeam 4 are equipped with drive components 5 to drive the housing 2 to carry the cargo along the I-beam slide rail 1. The housing 2 is equipped with support adjustment mechanisms 7 on both sides to correct the driving posture of the housing 2.
[0047] The drive assembly 5 includes a partition 501, a friction adjustment assembly 6, and a roller 507. The partition 501 is centrally fixed inside the housing 2. A drive motor 502 is provided on the lower end surface inside the housing 2. The output end of the drive motor 502 is connected to a rotating shaft 503. The shaft of the rotating shaft 503 is rotatably connected to the partition 501.
[0048] Friction adjustment components 6 are located on both sides of the inner wall of the housing 2. A support shaft 504 connects the friction adjustment components 6. A drive roller 505 is mounted on the support shaft 504. The drive roller 505 is in contact with the lower end face of the I-beam slide rail 1. A bevel gear set 506 is provided between the upper end of the rotating shaft 503 and the shaft of the support shaft 504. The bevel gear set 506 includes two bevel gears, which are respectively mounted on the upper ends of the support shaft 504 and the rotating shaft 503 and mesh with each other. Figure 4 As shown, a support frame is also provided on the partition 501 and is rotatably connected to the upper end of the rotating shaft 503 to improve the stability of the bevel gear during the rotation of the rotating shaft 503.
[0049] Roller 507 is rotatably connected to the lower end of crossbeam 4 and rolls in contact with the groove of I-beam slide rail 1. Note that the width of crossbeam 4 should be sufficient to install roller 507 and should not be too wide. The thickness of crossbeam 4 should also be 0.5-1 cm thinner than the thickness of I-beam slide rail 1 to ensure the bending ability of crossbeam 4.
[0050] When the suspended conveyor is in operation, the rollers 507 and the crossbeam 4 bear the weight of the entire device. The drive motor 502 drives the drive roller 505 to rotate through the shaft 503 and bevel gear transmission, thereby driving the entire housing 2 to move forward along the I-beam slide rail 1. During the movement of the housing 2 along the I-beam slide rail 1, since the rollers 507 and the drive roller 505 are in line contact with the I-beam slide rail 1, although it can rise and fall along the slope of the I-beam slide rail 1, it is very easy to swing back and forth. Therefore, the support adjustment mechanism 7 will dynamically adjust the distance between the two ends of the housing 2 and the lower end face of the I-beam slide rail 1 at all times to avoid collision.
[0051] By using drive component 5, the original multi-wheel combination drive is changed to a dual-wheel drive with drive roller 505 and roller 507 clamping each other from top to bottom. With the support and adjustment mechanism 7, the vehicle body is stabilized. When passing through the arc track, there will be no jamming due to the inability of the vehicle body to twist relative to it. This makes the suspended conveyor device adaptable to the lifting arc track, improves the flexibility of the suspended conveyor system's line layout, and reduces the system's complexity and cost.
[0052] The friction adjustment component 6 includes a lifting groove 601 and a threaded hole 603. The lifting groove 601 is symmetrically opened on both sides of the inner wall of the housing 2. The lifting block 602 is slidably connected in the lifting groove 601. The support shaft 504 is rotatably connected between the two lifting blocks 602 through a bearing. When the drive motor 502 drives the support shaft 504 to rotate, it will not interfere with the lifting blocks 602 on both sides.
[0053] Threaded holes 603 are formed on both sides of the housing 2 and extend downward below the lifting groove 601. A lifting rod 604 is threaded into the threaded hole 603. A compression spring 605 is connected between the lifting rod 604 and the lifting block 602 to adjust the friction between the drive roller 505 and the I-beam slide rail 1. The upper end of the compression spring 605 is fixedly connected to the lifting block 602, and the lower end of the compression spring 605 is rotatably connected to the upper end of the lifting rod 604. At the same time, the base of the compression spring 605 is slidably connected to the inner wall of the lifting groove 601 through a sliding strip to ensure that the rotation of the lifting rod 604 will not interfere with the compression spring 605. The rotating shaft 503 is a telescopic rotating shaft.
[0054] During actual operation of the suspended conveyor, the lifting rod 604 applies sufficient thrust to the lifting block 602 via the compression spring 605 to ensure the friction between the drive roller 505 and the I-beam slide rail 1. Even if there are errors in the track thickness during operation, the continuous pressure of the compression spring 605 can ensure continuous power output, resulting in a high fault tolerance rate. If the drive roller 505 wears down after long-term use, leading to insufficient friction between the drive roller 505 and the I-beam slide rail 1, the deformation of the compression spring 605 can be adjusted by rotating the lifting rod 604, thereby adjusting the friction between the drive roller 505 and the I-beam slide rail 1. However, after adjustment, the support shaft 504 will rise, so the extension and retraction of the rotating shaft 503 needs to be adjusted simultaneously to ensure effective meshing of the two gears in the bevel gear set 506. Furthermore, based on the principle that different driving forces are required for different cargo weights, the friction between the drive roller 505 and the I-beam slide rail 1 can be reduced when the cargo weight is low, and increased when the cargo weight is high. Improve the energy efficiency of this suspended conveyor system.
[0055] The friction adjustment component 6 enables flexible adjustment of the friction between the drive roller 505 and the I-beam slide rail 1. This allows for the compensation of friction by rotating the lifting rod 604 when the drive roller 505 wears out, reducing maintenance costs. It also allows for precise setting of the drive friction according to the weight requirements of the goods, significantly improving energy utilization and reducing overall energy consumption. Furthermore, if the track has a certain thickness error, the continuous pressure of the compression spring 605 can ensure continuous power output, resulting in a high fault tolerance rate.
[0056] The support adjustment mechanism 7 includes limit grooves 701 and an expansion compartment 705. There are four limit grooves 701, symmetrically located at the left and right ends of the housing 2. A liftable positioning frame 702 is slidably connected within each limit groove 701. Adjustment rods 703 are symmetrically arranged on the upper surface of the positioning frame 702. The rods 703 pass through a through hole at the upper end of the housing 2 and are fitted with pulleys 704. The pulleys 704 abut against the lower end of the I-beam slide rail 1 to maintain the balance of the left and right ends of the housing 2. Figure 5 As shown, the lower end face of the I-beam slide rail 1 can also be provided with a groove that matches the pulley 704, further improving the stability of the housing 2 during movement.
[0057] The expansion compartment 705 is located at both ends of the bottom of the housing 2. The expansion compartment 705 is equipped with a power unit 9. The output end of the power unit 9 is connected to an adjusting screw 706. The sliding part on the adjusting screw 706 is connected to the positioning frame 702 to drive the positioning frame 702 to rise and fall. The expansion compartment 705 is also equipped with a detection mechanism 8 to determine the angle between the housing 2 and the I-beam slide rail 1. If the extension amount of the adjusting rods 703 on both sides is the same, it indicates that the housing 2 and the I-beam slide rail 1 are parallel.
[0058] When the suspended conveyor moves in the horizontal section of the I-beam slide rail 1, the pulley 704 abuts against the lower end face of the I-beam slide rail 1 and the two adjusting rods 703 extend by the same amount, maintaining the balance of the left and right ends of the housing 2.
[0059] When the suspended conveyor enters the arc section from the horizontal section of the I-beam slide rail 1, if the arc is Figure 9 The convex arc shown in a1 is then as follows: Figure 10 As shown in (b), the left pulley 704 is still attached to the bottom of the I-beam slide rail 1, while the right pulley 704 separates from the lower end face of the I-beam slide rail 1. Subsequently, the power unit 9 should drive the adjusting screws 706 on both sides to rotate synchronously, causing the adjusting rods 703 and pulleys 704 on both sides to rise synchronously. During the rising process, although the extension of the left adjusting rod 703 and pulley 704 increases, they always remain attached to the lower end face of the I-beam slide rail 1. The entire housing 2 rotates slightly counterclockwise around the contact line between the drive roller 505 and the I-beam slide rail 1, until the right adjusting rod 703 drives the pulley 704 to contact the bottom surface of the arc-shaped section of the I-beam slide rail 1. At this time, the state of the housing 2 is as follows:Figure 10 As shown in (c) above. Its state after housing 2 has fully entered the bend is as follows. Figure 10 As shown in (d), at this time the tangent at the contact point between the housing 2 and the I-beam slide rail 1 and the drive roller 505 remains parallel.
[0060] When the suspended conveyor enters the arc section from the inclined section of the I-beam slide rail 1, if the arc is Figure 9 The convex arc shown in a2 in the figure also requires the adjusting rods 703 and pulleys 704 on both sides to extend synchronously and rotate the housing 2 slightly counterclockwise to ensure that the tangent at the contact point between the housing 2 and the I-beam slide rail 1 and the drive roller 505 remains parallel.
[0061] When the suspended conveyor enters from the inclined section or the horizontal section of the I-beam slide rail 1 respectively, as... Figure 9 When the arc is concave as shown in b1 or b2, since it is a concave arc, it is necessary to slightly rotate the housing 2 clockwise by synchronously contracting the adjusting rods 703 and pulleys 704 on both sides to ensure that the tangent at the contact point between the housing 2 and the I-beam slide rail 1 and the drive roller 505 remains parallel. (Reference) Figure 11 As shown in (a) and (b), if the adjusting rod 703 and pulley 704 do not retract into the housing 2, the inner arc surface of the I-beam slide rail 1 will obstruct the movement of the pulley 704 on the right.
[0062] By supporting the adjustment mechanism 7, the extension and retraction of the adjustment rods 703 and pulleys 704 on both sides are kept consistent, so that the housing 2 always remains parallel to the I-beam slide rail 1 when moving horizontally. The adjustment rods 703 and pulleys 704 on both sides of the housing 2 retract and extend synchronously, ensuring that the housing 2 can smoothly enter and leave the slide rail. At the same time, when the housing 2 enters the arc section of the I-beam slide rail 1, it always remains parallel to the tangent at the contact point between the I-beam slide rail 1 and the drive roller 505, so that the housing 2 is always in the optimal posture during the movement and will not collide. Moreover, the throughput efficiency and passage fault tolerance are the highest in this posture.
[0063] The detection mechanism 8 includes a sliding sleeve 801 and a laser emitter 804. The sliding sleeve 801 is symmetrically installed in the expansion compartments 705 on both sides of the housing 2, penetrating the lower housing of the housing 2. A probe 802 is slidably connected to the upper opening of the sliding sleeve 801. An electromagnetic component 803 is embedded in the lower end of the probe 802 and the lower side of the sliding sleeve 801. The electromagnetic component 803 consists of a permanent magnet and an electromagnet. The permanent magnet is located at the end of the probe 802 inside the sliding sleeve 801, and the electromagnet is located at the bottom of the sliding sleeve 801. When the electromagnet is energized, it generates a repulsive force on the permanent magnet, pushing the probe 802 upward. The rolling part at the top of the probe 802 contacts the lower end face of the I-beam slide rail 1 through the thrust provided by the electromagnetic component 803. The probe 802 is located outside the pulley 704, which ensures that the probe 802 contacts or senses the arc surface first and adjusts the extension amount in advance, avoiding the adjustment rod 703 and pulley 704 from contacting the arc surface too early and getting stuck.
[0064] A laser emitter 804 is mounted on the rod of one probe 802 to emit a laser beam parallel to the housing 2. A receiver 805 is longitudinally mounted on the other probe 802 to receive the laser beam. A controller 10 is located at the lower end of the partition 501, and the controller 10 is electrically connected to the receiver 805 and the regulating motor 901 via wires. Figure 10 As shown in (a), when the housing 2 is parallel to the slide rail, the laser beam is directed at the middle of the receiver 805. When the position of the receiver 805 receiving the laser changes, the change in relative position can be used to determine whether the housing 2 is about to enter a concave arc or a convex arc.
[0065] When the suspended conveyor enters from the inclined section or the horizontal section of the I-beam slide rail 1 respectively, as... Figure 9 When the convex arc shown in a1 or a2 is reached, the probe 802 at the advancing end will drive the receiver 805 to rise relative to the laser emitter 804 under the repulsive force of the electromagnetic component 803. After the lower end of the receiver 805 receives the laser beam, it will feed back the electrical signal to the controller 10, and the controller 10 will determine that it has entered the convex arc.
[0066] When the suspended conveyor enters from the inclined section or the horizontal section of the I-beam slide rail 1 respectively, as... Figure 9 When the concave arc shown in b1 or b2 is reached, the probe 802 at the advancing end will be resisted by the arc surface of the slide rail, thereby overcoming the repulsive force of the electromagnetic component 803 and driving the receiver 805 to descend relative to the laser emitter 804. After the upper end of the receiver 805 receives the laser beam, it will feed back the electrical signal to the controller 10, and the controller 10 will determine that it has entered the concave arc.
[0067] The detection mechanism 8 enables the pre-judgment of different arc shapes before the housing 2 enters the bend of the I-beam slide rail 1. The judgment logic is simple and clear, which allows the controller 10 to accurately issue control commands to adjust the extension and retraction of the adjusting rod 703 and the pulley 704, thereby ensuring the smooth entry and exit of the housing 2 from the bend.
[0068] In this embodiment, the receiver 805 is located on the probe 802 at the front end of the housing 2. If the positions of the receiver 805 and the laser emitter 804 are swapped, the judgment logic is reversed.
[0069] The power unit 9 includes an adjustment motor 901, and the number of adjustment motors 901 is one or two;
[0070] When there are two regulating motors 901, the two regulating motors 901 are respectively set in the two expansion compartments 705. The output ends of the two regulating motors 901 are connected to the lower end of the regulating screw 706 through the gearbox to output power. Since the regulating rods 703 and pulleys 704 at both ends of the housing 2 need to extend and retract synchronously, the two regulating motors 901 need to be driven synchronously.
[0071] Alternatively, when there is only one adjusting motor 901, the adjusting motor 901 is set in any expansion compartment 705. The output end of the adjusting motor 901 is connected to the lower end of the adjusting screw 706 through a gearbox. The lower ends of the adjusting screws 706 on both sides are provided with synchronous belts 902 to ensure that the two rotate synchronously.
[0072] The speed of motor 901 should be set after taking into account the curvature of the I-beam slide rail 1 and the speed of drive roller 505.
[0073] A tensioning frame 903 is provided on the lower end face inside the housing 2. When the length of the synchronous belt 902 is short, the tension does not need to be adjusted due to the limited deformation. However, when the synchronous belt 902 is long, a tensioning wheel must be installed on the tensioning frame 903 to adjust the tension of the synchronous belt 902.
[0074] The lower end of the lifting rod 604 is provided with an internal hexagonal hole, which allows the lifting rod 604 to be rotated directly through the internal hexagonal hole, improving the ease of operation.
[0075] Working principle: When the suspended conveyor is in operation, the roller 507 and the crossbeam 4 bear the weight of the entire device. The drive motor 502 drives the drive roller 505 to rotate through the rotating shaft 503 and bevel gear transmission, thereby driving the entire housing 2 to move forward along the I-beam slide rail 1.
[0076] When the suspended conveyor enters from the inclined section or the horizontal section of the I-beam slide rail 1 respectively, as... Figure 9When the laser beam is encountered at the convex arc shown in a1 or a2, the probe 802 at the advancing end will cause the receiver 805 to rise relative to the laser emitter 804 under the repulsive force of the electromagnetic component 803. After the lower end of the receiver 805 receives the laser beam, it will feed back an electrical signal to the controller 10, which will determine that it has entered the convex arc. Then, the adjusting motor 901 will be started to drive the adjusting screws 706 on both sides to rotate synchronously, thereby driving the adjusting rods 703 and pulleys 704 on both sides to rise synchronously. The entire housing 2 will then rotate slightly counterclockwise around the contact line between the drive roller 505 and the I-beam slide rail 1, so that the right adjusting rod 703 drives the pulley 704 to maintain contact with the bottom surface of the arc section of the I-beam slide rail 1. The tangents at the contact points of the housing 2, the I-beam slide rail 1, and the drive roller 505 will remain parallel until the curve is passed.
[0077] When the suspended conveyor enters from the inclined section or the horizontal section of the I-beam slide rail 1 respectively, as... Figure 9 When the laser beam is encountered at the concave arc shown in b1 or b2, the probe 802 at the advancing end will be resisted by the arc surface of the slide rail, thereby overcoming the repulsive force of the electromagnetic component 803 and causing the receiver 805 to descend relative to the laser emitter 804. After the upper end of the receiver 805 receives the laser beam, it feeds back an electrical signal to the controller 10. The controller 10 determines that it has entered the concave arc and then starts the adjusting motor 901 to drive the adjusting screws 706 on both sides to rotate synchronously, causing the adjusting rods 703 and pulleys 704 on both sides to retract synchronously into the housing 2. The entire housing 2 then rotates slightly clockwise around the contact line between the drive roller 505 and the I-beam slide rail 1, so that the tangents at the contact points of the housing 2, the I-beam slide rail 1, and the drive roller 505 remain parallel until the bend is passed.
