Description

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 flow 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: The commonly used self-adaptive suspension conveying device at present mainly consists 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 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 complexity and cost of the system. SUMMARY

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0019] Please refer to Figures 1-11 As shown in the figure, the present application provides a kind of adaptive suspension conveying device for automatic production line technical scheme: a kind of adaptive suspension conveying device for automatic production line, including I-shaped slide rail 1 and machine shell 2, the lower end of machine shell 2 is fixedly connected for suspending or binding goods goods shelf. The upper end of machine shell 2 is fixedly installed with hanging piece 3, the upper end of hanging piece 3 is fixedly connected with cross beam 4, machine shell 2 is hung below I-shaped slide rail 1 through hanging piece 3 and cross beam 4, as shown in the figure, Figure 1As shown, the crossbeam 4 is inserted into the slot on both sides of the I-shaped slide rail 1 to bear the weight of the entire device and the goods below, the driving assembly 5 is installed on the shell 2 and the crossbeam 4 to drive the shell 2 to carry the goods to move along the I-shaped slide rail 1, and the support adjusting mechanism 7 is installed on both sides of the shell 2 to correct the driving posture of the shell 2.

[0020] The driving assembly 5 comprises a partition plate 501, a friction force adjusting assembly 6 and a roller 507, the partition plate 501 is fixedly installed in the center of the shell 2, a driving motor 502 is arranged on the lower end face in the shell 2, the output end of the driving motor 502 is connected with a rotating shaft 503, and the shaft body of the rotating shaft 503 is rotationally connected with the partition plate 501.

[0021] The friction force adjusting assembly 6 is arranged on both sides of the inner wall of the shell 2, the support shaft 504 is connected between the friction force adjusting assemblies 6, the driving roller 505 is arranged on the support shaft 504, the driving roller 505 is in contact with the lower end face of the I-shaped slide rail 1, the bevel gear set 506 is arranged between the upper end of the rotating shaft 503 and the shaft body of the support shaft 504, the bevel gear set 506 comprises two bevel gears, the two bevel gears are respectively installed on the upper end of the support shaft 504 and the rotating shaft 503 and are in meshing engagement, and the bevel gear set 506 drives the driving roller 505 to rotate. Figure 4 As shown, the partition plate 501 is further provided with a support frame rotationally connected with the upper end of the rotating shaft 503 for improving the stability of the bevel gear during the rotation of the rotating shaft 503.

[0022] The roller 507 is rotationally connected with the lower end of the crossbeam 4 and is in rolling contact with the sliding groove of the I-shaped slide rail 1, it should be noted that the width of the crossbeam 4 should be able to install the roller 507, and the width of the crossbeam 4 cannot be too wide, and the thickness of the crossbeam 4 should be 0.5-1 cm thinner than the thickness of the I-shaped slide rail 1, so as to ensure the bending capacity of the crossbeam 4.

[0023] During the operation of the suspension conveying device, the roller 507 and the crossbeam 4 bear the weight of the entire device, the driving motor 502 drives the driving roller 505 to rotate through the rotating shaft 503 and the bevel gear transmission, so as to drive the entire shell 2 to move forward along the I-shaped slide rail 1. During the movement of the shell 2 along the I-shaped slide rail 1, since the roller 507 and the driving roller 505 are in linear contact with the I-shaped slide rail 1, although they can ascend and descend along the slope of the I-shaped slide rail 1, they are prone to swing forward and backward, so the support adjusting mechanism 7 dynamically adjusts the distance between the two ends of the shell 2 and the lower end face of the I-shaped slide rail 1 at any time to avoid collision.

[0024] Through the driving assembly 5, the original multi-wheel combined driving is changed into the upper and lower clamping double-wheel driving of the driving roller 505 and the roller 507, the body is stabilized by the support adjusting mechanism 7, and when passing through the arc-shaped track, the body cannot be relatively twisted to cause jamming, so that the suspension conveying device has the adaptation ability with the lifting arc-shaped track, the line layout flexibility of the suspension conveying system is improved, and the complexity and cost of the system are reduced.

[0025] The friction force adjusting assembly 6 comprises a lifting groove 601 and a threaded hole 603. The lifting groove 601 is symmetrically arranged on the inner wall of the shell 2, the lifting block 602 is slidingly connected in the lifting groove 601, and the support shaft 504 is rotatably connected between the two lifting blocks 602 through bearings, so that the driving motor 502 can drive the support shaft 504 to rotate without interfering with the two lifting blocks 602.

[0026] The threaded hole 603 is arranged on the shell on the two sides of the shell 2 and penetrates downward below the lifting groove 601, the lifting rod 604 is threadedly connected in the threaded hole 603, the compression spring 605 is connected between the lifting rod 604 and the lifting block 602 for adjusting the friction force between the driving roller 505 and the I-shaped sliding rail 1, the upper end of the compression spring 605 is fixedly connected with the lifting block 602, the lower end of the compression spring 605 is rotatably connected with the upper end of the lifting rod 604, and the base of the compression spring 605 is slidingly connected with the inner wall of the lifting groove 601 through a sliding strip, so that the rotation of the lifting rod 604 does not interfere with the compression spring 605, and the rotating shaft 503 is a telescopic rotating shaft.

[0027] During actual operation of the suspension conveying device, the lifting rod 604 applies sufficient pushing force to the lifting block 602 through the compression spring 605, so as to ensure the friction force of the contact surface between the driving roller 505 and the I-shaped sliding rail 1. Even if there is an error in the thickness of the track during operation, the continuous pressure of the compression spring 605 can ensure the continuous output of power, and the fault tolerance is high. If the driving roller 505 is worn after long-term use, the contact surface friction force between the driving roller 505 and the I-shaped sliding rail 1 is insufficient, and the deformation amount of the compression spring 605 can be adjusted by rotating the lifting rod 604, so as to adjust the friction force between the driving roller 505 and the I-shaped sliding rail 1. However, after adjustment, the support shaft 504 will rise, so the telescopic amount of the rotating shaft 503 needs to be adjusted synchronously, so as to ensure the effective meshing of the two gears in the bevel gear set 506. Moreover, according to the principle that the required driving force is different according to the weight of the goods, the friction force between the driving roller 505 and the I-shaped sliding rail 1 can be reduced when the weight of the goods is low, and the friction force between the driving roller 505 and the I-shaped sliding rail 1 can be increased when the weight of the goods is high. The energy utilization rate of the suspension conveying device is improved.

[0028] Through the friction force adjusting assembly 6, flexible adjustment of the friction force between the driving roller 505 and the I-shaped sliding rail 1 is realized. The friction force can be compensated by rotating the lifting rod 604 when the driving roller 505 is worn later, so as to reduce the maintenance cost. The driving friction force can also be accurately set according to the weight of the goods, which significantly improves the energy utilization rate and reduces the overall energy consumption. Moreover, if there is a certain thickness error in the track, the continuous pressure of the compression spring 605 can also ensure the continuous output of power, and the fault tolerance is high.

[0029] The support adjusting mechanism 7 comprises a limiting groove 701 and an expansion bin 705. The limiting groove 701 is symmetrical and comprises four limiting grooves arranged at the left and right ends of the shell 2. The limiting groove 701 is slidably connected with a liftable positioning frame 702. The upper end surface of the positioning frame 702 is symmetrically provided with an adjusting rod 703. The rod body of the adjusting rod 703 is provided with a pulley 704 through the through hole of the upper end of the shell 2. The pulley 704 abuts against the lower end surface of the I-shaped slide rail 1 to keep the balance of the left and right ends of the shell 2. As shown in Figure 5 , the lower end surface of the I-shaped slide rail 1 can also be provided with a matching embedding groove matched with the pulley 704 to further improve the stability of the shell 2 during movement.

[0030] The expansion bin 705 is arranged at the two ends of the bottom of the shell 2. The expansion bin 705 is provided with a power unit 9. The output end of the power unit 9 is connected with an adjusting lead screw 706. The sliding part on the adjusting lead screw 706 is connected with the positioning frame 702 to drive the lifting of the positioning frame 702. The expansion bin 705 is also provided with a detection mechanism 8 for judging the included angle between the shell 2 and the I-shaped slide rail 1. If the extension amounts of the two adjusting rods 703 are the same, it indicates that the shell 2 keeps parallel with the I-shaped slide rail 1.

[0031] When the suspension conveying device moves on the horizontal section of the I-shaped slide rail 1, the pulley 704 abuts against the lower end surface of the I-shaped slide rail 1 and the extension amounts of the two adjusting rods 703 are the same, thereby keeping the balance of the left and right ends of the shell 2.

[0032] When the suspension conveying device enters the arc section from the horizontal section of the I-shaped slide rail 1, if the arc is a convex arc as shown by a1 in Figure 9 , at this time, as shown by (b) in Figure 10 , the left pulley 704 also abuts against the lower end surface of the I-shaped slide rail 1, and the right pulley 704 is separated from the lower end surface of the I-shaped slide rail 1. Then, the power unit 9 drives the synchronous rotation of the two adjusting lead screws 706 to drive the synchronous lifting of the two adjusting rods 703 and the pulleys 704. During the lifting process, the left adjusting rod 703 and the pulley 704 always abut against the lower end surface of the I-shaped slide rail 1 although the extension amount increases. The whole shell 2 slightly rotates counterclockwise with the contact line between the driving roller 505 and the I-shaped slide rail 1 as the axis, until the right adjusting rod 703 drives the pulley 704 to contact the bottom surface of the arc section of the I-shaped slide rail 1. At this time, the state of the shell 2 is shown as (c) in Figure 10 . After the shell 2 completely enters the bend, the state is shown as (d) in Figure 10 . At this time, the tangent lines at the contact points between the shell 2 and the I-shaped slide rail 1 and the driving roller 505 keep parallel.

[0033] When the suspension conveying device enters the arc section from the inclined section of the I-shaped slide rail 1, if the arc is a concave arc as shown by a2 in Figure 9The 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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 When the position of the receiver 805 changes, the change of relative position can be used to determine that the cabinet 2 is about to enter the concave arc or the convex arc.

[0038] When the suspension conveying device enters the convex arc as shown in a1 or a2 of FIG. 4 from the inclined section or the horizontal section of the I-shaped slide rail 1, the probe rod 802 at the advancing end will drive the receiver 805 to rise relative to the laser emitter 804 under the repulsion of the electromagnetic assembly 803, and then the lower end of the receiver 805 receives the laser beam and feeds back an electric signal to the controller 10, so that the controller 10 determines that the convex arc is entered. Figure 9

[0039] When the suspension conveying device enters the concave arc as shown in b1 or b2 of FIG. 5 from the inclined section or the horizontal section of the I-shaped slide rail 1, the probe rod 802 at the advancing end will be subjected to the resistance of the arc surface of the slide rail, so as to overcome the repulsion of the electromagnetic assembly 803 to drive the receiver 805 to descend relative to the laser emitter 804, and then the upper end of the receiver 805 receives the laser beam and feeds back an electric signal to the controller 10, so that the controller 10 determines that the concave arc is entered. Figure 9 Through the detection mechanism 8, the pre-determination of different arcs before the cabinet 2 enters the bend of the I-shaped slide rail 1 is realized, the determination logic is simple and clear, so that the controller 10 can accurately issue a control instruction to adjust the extension amount of the adjusting rod 703 and the pulley 704, thereby ensuring the smooth entry and exit of the cabinet 2 into the bend.

[0040] In the embodiment, the receiver 805 is located on the probe rod 802 at the advancing end of the cabinet 2, and if the positions of the receiver 805 and the laser emitter 804 are inversed, the determination logic is opposite.

[0041] The power part 9 includes an adjusting motor 901, and the number of the adjusting motor 901 is one or two. When the number of the adjusting motor 901 is two, the two adjusting motors 901 are arranged in the two extension warehouses 705 respectively, and the output ends of the two adjusting motors 901 are connected to the lower ends of the adjusting lead screws 706 through the setting of a gearbox to output power, and since the adjusting rod 703 and the pulley 704 at both ends of the cabinet 2 need to be synchronously extended and retracted, the two adjusting motors 901 need to be synchronously driven. Alternatively, when the number of the adjusting motor 901 is one, the adjusting motor 901 is arranged in any extension warehouse 705, and the output end of the adjusting motor 901 is connected to the lower end of the adjusting lead screw 706 through the setting of a gearbox, and the lower ends of the adjusting lead screws 706 at both sides are provided with a synchronous belt 902 for ensuring the synchronous rotation of the two adjusting lead screws 706.

[0042] ​​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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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 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.

[0047] 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.
