Description

Technical Field

[0001] The present invention relates to the technical field of suspension conveying, and in particular to an automatic suspension conveying device for spraying parts. Background Art

[0002] During the spraying process of spray-coated parts, overhead conveyors are widely used in the transfer process. Overhead conveyors are a common type of continuous conveying equipment. Overhead conveyors typically consist of a track system, a drive unit, a carrier (such as a hanging basket or pulley), a control system, and auxiliary equipment (such as a tensioner and safety devices). The track system defines the conveying path and provides support and guidance for the overhead conveyor. The drive unit provides power, driving the traction chain along the track. The carrier directly carries the material and moves with the movement of the traction chain by connecting to it. Finally, the control system is responsible for scheduling and monitoring the entire system's operations, such as speed regulation and start / stop control.

[0003] However, the traditional carrier is directly fixed on the traction chain, so that the traction chain not only needs to receive the thrust of the drive device, but also the downward pull of the material when the material is suspended. Especially when the material is heavy, it is easy to damage the traction chain, resulting in unstable transportation. Moreover, as the traction chain ages, local deformation causes the traction chain to vibrate when passing through the gear set. The vibration is transmitted to the material, which also affects the stability of the material. Especially when conveying the sprayed parts into the spraying operation area, the shaking sprayed parts will cause uneven spraying, thereby affecting product quality. Therefore, the traditional hanging conveying device has a short service life, operates unstablely, and cannot meet production needs. Summary of the Invention

[0004] The present invention aims to solve the problem that the traditional suspension conveying device is easy to damage the traction chain and the operation is not smooth, and to provide an automatic suspension conveying device for sprayed parts, which has the advantages of reducing the pressure on the conveying chain, extending its service life, and being smooth and reliable during transportation.

[0005] In the first aspect, to achieve the above-mentioned purpose, the technical solution adopted by the present invention is:

[0006] An automatic suspension conveyor device for sprayed parts, comprising a conveyor frame, a conveyor chain driven by an electric drive gear set mounted on the conveyor frame, a plurality of tensioning pulleys mounted on the conveyor chain, a tensioning mechanism and a suspension mechanism, the tensioning mechanism being fixed to the conveyor chain via a mounting seat, the suspension mechanism being movably mounted on a slide rail provided on the conveyor frame, the tensioning mechanism being connected to the suspension mechanism via a detachable connecting piece for transmitting the tension of the conveyor chain to the suspension mechanism;

[0007] The detachable connecting part includes a connecting push rod with an arc-shaped structure, one end of the connecting push rod is connected to a connection and disconnection control mechanism, and the connection push rod is controlled by the connection and disconnection control mechanism to extend and retract along an arc trajectory, and the other end contacts the suspension mechanism when the connecting push rod is fully extended, and the contact position is on the side opposite to the moving direction of the suspension mechanism.

[0008] Preferably, the detachable connecting part also includes a limit rod with the same arc-shaped structure, one end of which is connected to another connection and disconnection control mechanism, and the limit rod is also controlled by the connection and disconnection control mechanism to extend and retract along the arc-shaped trajectory, and the other end contacts the suspension mechanism when the limit rod is fully extended, and the contact position is on one side of the movement direction of the suspension mechanism.

[0009] Preferably, protective sleeves are provided on the ends of the connecting push rod and the limiting rod that are in contact with the suspension mechanism.

[0010] Preferably, the connection and disconnection control mechanism includes an arc-shaped slot, a spring and an electromagnet, and the connected parts are retracted into the arc-shaped slot by the magnetic attraction provided by the electromagnet, and are pulled out of the arc-shaped slot by the spring.

[0011] Preferably, the suspension mechanism includes a connecting seat with a connecting hole provided on the connecting seat, a connecting push rod inserted into the connecting hole and in contact with the suspension mechanism, and a hole diameter of the connecting hole is larger than a rod diameter of the connecting push rod, and a shock-absorbing pad is provided on the side wall of the connecting hole.

[0012] Preferably, the suspension mechanism also includes a suspension rod, one end of which is equipped with a roller and connected to the slide rail through the roller, and the other end is equipped with a hook through a rotating seat. The hook is used to hang the spray part, and the hook can rotate with the suspension rod as the axis through the rotating seat.

[0013] Preferably, the pulling mechanism also includes a rotating drive member, which includes a variable electromagnetic module. The variable electromagnetic module can change its magnetism. At least four magnet pieces are distributed circumferentially around the rotating seat, and the magnetism between adjacent magnet pieces is opposite. When the variable electromagnetic module changes its magnetism to be the same as the magnet piece currently facing, the repulsive force pushes the rotating seat to rotate once until the adjacent magnet piece faces the variable electromagnetic module.

[0014] Preferably, the position of the magnet piece installed on the rotating seat is offset from the central axis of the rotating seat, and the variable electromagnetic module is opposite to each rotated magnet piece. The variable electromagnetic module changes the magnetism by changing the direction of the current.

[0015] Preferably, the device also includes a loading conveyor belt and a unloading conveyor belt, a spraying operation area is installed between the loading conveyor belt and the unloading conveyor belt, the moving speed of the sprayed parts on the loading conveyor belt and the unloading conveyor belt is less than the moving speed of the suspension mechanism, and the loading conveyor belt and the unloading conveyor belt both include an ascending section, a horizontal section and a descending section arranged in sequence along the conveying direction.

[0016] Preferably, a sliding cable is installed on the conveying frame, and a power supply frame is installed on the tension mechanism, and the power supply frame is electrically connected to the sliding cable.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the suspension mechanism and tension mechanism connected by detachable connectors, the conveyor chain only needs to provide the pulling force for conveying, without having to bear the gravity of the suspension, thus reducing the loss of the conveyor chain, improving the stability of the device operation and extending its service life.

[0019] 2. As a detachable suspension mechanism and tension mechanism, it is also convenient to disassemble the suspension mechanism. When the demand for spray parts transportation is small, the tension mechanism does not have to load the idle suspension mechanism. Selecting a suitable suspension mechanism for connection ensures the stability of spray parts transportation and can also reduce the loss of transportation kinetic energy. Moreover, the non-fixed connection between the suspension mechanism and the tension mechanism is easier to make a shock-absorbing structure. In the case of shaking of the tension mechanism caused by deformation of the conveying chain, the vibration will not be transmitted to the suspension mechanism, thereby ensuring the stability of the suspended spray parts.

[0020] 3. The present invention also provides a structure that can drive the hook of the suspension mechanism to rotate without contact, so that the sprayed parts can rotate when they are transported to the spraying operation area, thereby improving the spraying effect. The entire suspension mechanism only serves as passive suspension and rotation, without any other power device, which is more durable and saves production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figure 1 and Figure 2 As shown, an automatic suspension conveying device for sprayed parts is disclosed, including a conveying frame 1, a conveying chain 4 driven by an electric drive gear set is installed on the conveying frame 1, and a plurality of tensioning pulleys 5 are installed on the conveying chain 4. The shape of the conveying frame 1 can be designed according to the conveying path, and the conveying chain 4 is installed on the conveying frame 1, and the electric drive gear set is connected to the conveying chain 4 by meshing. As the electric drive gear set rotates, the conveying chain 4 is driven to move in a circular motion on the path of the conveying frame 1, thereby realizing the circular conveying of the sprayed parts 32, and completing the spraying operation during the circulation process. The tensioning pulley 5 is also composed of small gears. A plurality of tensioning pulleys 5 are set, evenly distributed at various positions of the conveying chain 4, and the tensioning pulley 5 can adjust the distance between it and the conveying chain 4, thereby achieving the effect of tensioning the conveying chain 4 to ensure smooth conveying.

[0030] If the spraying part 32 wants to move with the conveyor chain 4, it needs to be fixed to the conveyor chain 4. In order to facilitate the loading and unloading of the spraying part 32, a hanging component is also required as an intermediate component to ensure that it is connected to the conveyor chain 4 while being able to hang the spraying part 32. Figure 2 As shown, the device also includes a tensioning mechanism 2 and a suspension mechanism 3. The tensioning mechanism 2 is fixed to the conveying chain 4 through a mounting seat 9. The suspension mechanism 3 is movably mounted on a slide rail 8 provided on the conveying frame 1. The tensioning mechanism 2 is connected to the suspension mechanism 3 through a detachable connecting member 10, which is used to transmit the tension of the conveying chain 4 to the suspension mechanism 3.

[0031] The traditional suspension conveying device has a pulling mechanism 2 and a suspension mechanism 3 that are integrated with each other. However, when this design structure suspends the spraying part 32, the self-weight of the spraying part 32 will be transferred to the conveying chain 4. Even if the conveying chain 4 is maintained in a tensioned state by the tensioning wheel 5, long-term downward pulling will cause the conveying chain 4 to be easily deformed, affecting its service life. The present invention adopts a detachable connection between the pulling mechanism 2 and the suspension mechanism 3 to isolate the weight of the spraying part 32 from being transferred to the conveying chain 4. The suspension mechanism 3 is responsible for suspending the spraying part 32, and the suspension mechanism 3 is installed on the slide rail 8, which is borne by the rail. The slide rail 8 adopts a rigid structure and is not easy to deform. The pulling mechanism 2 is only used to be fixed on the conveying chain 4 to pull the suspension mechanism 3 to move synchronously. Since the pulling mechanism 2 only provides pulling force in the moving direction of the conveying chain 4, the reaction force it receives is also a force in the reverse moving direction of the conveying chain 4, so that the conveying chain 4 will not be greatly damaged.

[0032] In order to ensure the stable connection between the tension mechanism 2 and the suspension mechanism 3, a detachable connector 10 is used as a component for connecting the two. Figure 3 As shown, the detachable connector 10 includes a connecting rod 17 with an arcuate structure. One end of the connecting rod 17 is connected to a connecting / disconnecting control mechanism 19. The connecting rod 17 is controlled by the connecting / disconnecting control mechanism 19 to extend and retract along an arcuate trajectory. When the connecting rod 17 is fully extended, the other end contacts the suspension mechanism 3, and the contact position is on the side opposite to the movement direction of the suspension mechanism 3. The detachable connector 10 uses the connecting rod 17 with an arcuate structure as the connecting rod. Compared with a straight rod, the stress on both ends of the connecting rod 17 can be evenly distributed throughout the rod body by the arcuate structure, making it less likely to break or deform. The extension and retraction along the arcuate trajectory is also to avoid occupying too much space when the connecting rod 17 extends and retracts. The connection position is on the side opposite to the movement direction of the suspension mechanism 3. Therefore, when reconnecting from a disconnected state, it is not necessary to precisely locate the moment of contact with the suspension mechanism 3. For example, taking the movement direction of the suspension mechanism 3 as the forward direction, the connecting rod 17 only needs to ensure that it can be fully extended when it is behind the suspension mechanism 3. Even if it is extended prematurely, it can still contact the suspension mechanism 3 and push the suspension mechanism 3 forward. The purpose of selecting the disconnection control mechanism 19 to realize the telescopic control of the connecting push rod 17 is to make the tension mechanism 2 and the suspension mechanism 3 have a connection-disconnected state, so as to maximize the advantages of the split design of the two. For example, when one of the two fails, the other can also be quickly separated, which is not only convenient for maintenance, but also does not affect the work. When the workload is small, you can also choose to reduce the use of the suspension mechanism 3 to avoid the tension mechanism 2 pulling the idle suspension mechanism 3 to move in a cycle, causing unnecessary energy loss.

[0033] As can be seen from the above, the connecting push rod 17 is connected to the rear of the suspension mechanism 3 to push the suspension mechanism 3 to move. Although the suspension mechanism 3 will be pushed forward a little distance due to inertia when touched, which does not affect the subsequent continuous pushing, in order to ensure the stability of the connection of the suspension mechanism 3, a limit rod 18 needs to be added, such as Figure 3 As shown, the detachable connector 10 also includes a limit rod 18 with a similar arc-shaped structure. One end of the limit rod 18 is connected to another disconnection control mechanism 19, and the disconnection control mechanism 19 also controls the limit rod 18 to extend and retract along an arc-shaped trajectory. When the limit rod 18 is fully extended, the other end contacts the suspension mechanism 3, and the contact position is on one side of the movement direction of the suspension mechanism 3. The limit rod 18 is arranged in front of the suspension mechanism 3, so that it can form a structure similar to a clamping arm with the connecting push rod 17. By clamping in both the front and rear directions, the suspension mechanism 3 is fixed, and then moves synchronously with the tension mechanism 2, thereby increasing the connection stability of the detachable connector 10. The limit rod 18 also has an arc-shaped structure to disperse the stress it is subjected to, avoiding breakage or deformation due to excessive contact force. The limit rod 18 is also controlled by the disconnection control mechanism 19 to separate from the suspension mechanism 3, thereby achieving complete disconnection of the tension mechanism 2 from the suspension mechanism 3.

[0034] In order to protect the connecting push rod 17 and the limiting rod 18, protective sleeves 25 are provided at the ends of the connecting push rod 17 and the limiting rod 18 that contact the suspension mechanism 3. The protective sleeves 25 can be made of rubber, which can provide protection while reducing noise during connection.

[0035] According to the purpose of connecting the push rod 17 and the limit rod 18, both need to have a fast response speed, and the two arc-shaped structures also move along the arc track. In order to meet the requirements of being able to move along the arc track and have a fast response speed, Figure 3 As shown, the disconnection control mechanism 19 includes an arc groove 21, a spring 20 and an electromagnet 22. The magnetic attraction provided by the electromagnet 22 controls the connected component to retract into the arc groove 21, and the spring 20 pulls the connected component out of the arc groove 21. The electromagnet 22 is used as the power component of the disconnection control mechanism 19, and the arc trajectory movement of the connecting push rod 17 or the limit rod 18 is controlled by magnetic attraction. It can be unaffected by the moving path, ensuring that the force is transmitted to the connecting push rod 17 or the limit rod 18, and can also reduce the arrangement of transmission components, reduce costs and failure rates. Here, the electromagnet 22 is used to provide the force for retracting the connecting push rod 17 or the limit rod 18, and the spring 20 provides the force for extending the connecting push rod 17 or the limit rod 18, which can achieve a rapid contraction effect. Figure 3 As shown, the push rod 17 and the limit rod 18 are extended at the same time. At this time, no current flows through the electromagnet 22 and no magnetism is generated. The push rod 17 and the limit rod 18 are pulled out of the arc groove 21 by the spring 20. When they need to be retracted, the following is formed: Figure 4As shown in the state diagram, the electromagnet 22 needs to be energized. The magnetic force will attract the connecting push rod 17 and the limit rod 18 to move along the arc groove 21 and contact the electromagnet 22. The spring 20 is also stretched to store energy for the next pop-up of the connecting push rod 17 and the limit rod 18. The magnetic attraction and pop-up method is used to achieve a rapid response of the disconnection control mechanism 19, which has a simple structure, low cost and is not prone to failure.

[0036] like Figure 3 and Figure 4 As shown, the suspension mechanism 3 includes a connecting seat 14, a connecting hole 23 is set on the connecting seat 14, the connecting push rod 17 is inserted into the connecting hole 23 and contacts the suspension mechanism 3, and the hole diameter of the connecting hole 23 is larger than the rod diameter of the connecting push rod 17, and a shock-absorbing pad 24 is set on the side wall of the connecting hole 23. According to the above, the connecting push rod 17 can contact the suspension mechanism 3 without high precision, but in order to avoid accidents during the pushing process, a connecting hole 23 needs to be set on the connecting seat 14. Since the connecting push rod 17 is extended to make contact, the connecting hole 23 needs to be set with a larger aperture to reduce the connection error, and the connecting push rod 17 transmits the thrust to the connecting seat 14 through the end, so a shock-absorbing pad 24 is set on the side wall of the connecting hole 23 to reduce the collision of the connecting hole 23 caused by the lateral shaking of the connecting push rod 17. The conveying chain 4 is long and locally deformed or aged, which will cause vibration when moving to the tensioning wheel 5 or the electric drive gear set. The vibration is transmitted to the suspension mechanism 3 through the tension mechanism 2, affecting the stability of the suspension. The use of the shock-absorbing pad 24 can reduce some vibrations and improve the operating stability of the suspension mechanism 3.

[0037] like Figure 2 As shown, the suspension mechanism 3 further includes a suspension rod 13, one end of which is mounted with a roller 12, which is connected to the slide rail 8 via the roller 12, and the other end of which is mounted with a hook 16 via a rotating seat 15. The hook 16 is used to suspend the spraying member 32, and the rotating seat 15 allows the hook 16 to rotate about the suspension rod 13 as an axis. The roller 12 is connected to the slide rail 8, providing a strong supporting force to support the weight of the suspended part, and the rotating seat 15 allows the hook 16 to rotate, so that the rotatable spraying member 32 can be sprayed more evenly during the spraying operation.

[0038] Since the suspension mechanism 3 is used to suspend heavy objects, in order to improve durability, the suspension mechanism 3 needs to be simple in structure and not prone to failure. Therefore, the rotation driving force of the rotating seat 15 cannot be directly installed on the suspension mechanism 3. The suspension mechanism 3 is relatively stationary with the tension mechanism 2 during operation, so it is best to install the structure of the driving rotating seat 15 on the tension mechanism 2. Figure 5As shown, the tension mechanism 2 also includes a rotary drive member 11, which includes a variable electromagnetic module 28. The variable electromagnetic module 28 can change its magnetism. At least four magnet pieces 27 are distributed circumferentially around the rotating base 15. The magnetism of adjacent magnet pieces 27 is opposite. When the variable electromagnetic module 28 changes its magnetism to the same as the magnet piece 27 it is currently facing, the repulsive force pushes the rotating base 15 to rotate once until the adjacent magnet piece 27 faces the variable electromagnetic module 28. The tension mechanism 2 also controls the rotation of the rotating base 15 through the principle of magnetism. The position of the magnet piece 27 mounted on the rotating base 15 is offset from the central axis of the rotating base 15. The variable electromagnetic module 28 is positioned opposite each rotated magnet piece 27. The variable electromagnetic module 28 changes its magnetism by changing the direction of the current.

[0039] The magnetism of the variable electromagnetic module 28 serves as the driving force. Since magnets 27 are positioned around the rotating base 15, the magnetism of the variable electromagnetic module 28 only needs to be equal to that of the opposing magnets 27. The repulsive force will push the magnets 27 apart. As long as the center of the magnets 27 is not on the axis of the rotating base 15, the thrust will cause the rotating base 15 to shift, causing the magnets 27 on the other side to face the variable electromagnetic module 28. Since the magnetism of adjacent magnets 27 is opposite, the magnetism of the current variable electromagnetic module 28 is also opposite to that of the current magnets 27. The two exert a magnetic attraction, ensuring that the rotating base 15 does not wobble or over-rotate after rotation. Simply changing the magnetism of the variable electromagnetic module 28 will cause the rotating base 15 to rotate again, until it completes one full rotation. Furthermore, by controlling the time interval between each rotation of the rotating base 15, the time interval between each rotation of the rotating base 15 can be controlled. This, in conjunction with the spraying equipment, ensures that the sprayed part 32 is fully sprayed.

[0040] like Figure 1As shown, the device also includes a loading conveyor belt 29 and a unloading conveyor belt 31. A spraying operation area 30 is installed between the loading conveyor belt 29 and the unloading conveyor belt 31. The movement speed of the spraying part 32 on the loading conveyor belt 29 and the unloading conveyor belt 31 is lower than the movement speed of the suspension mechanism 3. The loading conveyor belt 29 and the unloading conveyor belt 31 each include an ascending section 33, a horizontal section 34, and a descending section 35 arranged in sequence along the conveying direction. The loading conveyor belt 29 is used to transport the spraying part 32 so that the hook 16 of the suspension mechanism 3 can be hung on the spraying part 32. Since the speed at which the loading conveyor belt 29 transports the spraying part 32 is lower than the movement speed of the suspension mechanism 3, as the spraying part 32 moves from the ascending section 33 to the horizontal section 34, the rear suspension mechanism 3 overtakes the spraying part 32 and hangs the spraying part 32 through the hook 16 until it leaves the horizontal section 34 and enters the descending section 35. The spraying part 32 enters the spraying operation area 30 in mid-air, and the spraying part 32 in the spraying operation area 30 is sprayed. Rotate to spray in all directions, and finally the direction of the hook 16 is opposite to the direction when the spray part 32 is suspended. The hook 16 moves the spray part 32 from the ascending section 33 of the unloading conveyor belt 31 to the horizontal section 34. The conveyor belt of the horizontal section 34 supports the spray part 32 and the moving speed of the suspension mechanism 3, and the hook 16 is opposite to that before the spray part 32 was suspended. Naturally, the hook 16 is separated from the spray part 32, and finally the spray part 32 leaves the unloading conveyor belt 31 along the descending section 35. In this way, the automatic loading and unloading of the device can be realized, saving manpower.

[0041] like Figure 2 As shown, a trolley cable 6 is mounted on the conveyor frame 1, and a power supply frame 7 is mounted on the tension mechanism 2. The power supply frame 7 is electrically connected to the trolley cable 6. Since the tension mechanism 2 moves with the conveyor chain 4, traditional cable power supply cannot meet the usage requirements. The use of trolley power supply reduces the difficulty of wiring and also facilitates powering the detachable connector 10 and the connection and disconnection control mechanism 19.
