Description

Technical Field

[0001] The present application relates to the technical field of conveying equipment, and in particular to a multi-power conveying system. Background Art

[0002] Currently, ultra-high-speed roller conveyor systems are widely used in production lines such as automotive welding to automatically transport trolleys and load workpieces. However, in practice, some parts of the production line have different conveying cycles. For example, to transport workpieces to the target workstation at a faster speed, the trolley requires an ultra-high-speed roller conveyor on the outbound portion of the line. However, since the trolley has no process time to occupy the cycle, the return portion of the line can be equipped with a lower-speed conventional friction roller conveyor. This results in two different types of roller conveyors being used on the same line: an ultra-high-speed roller conveyor and a lower-speed conventional friction roller conveyor. However, these hybrid conveyor lines currently require the design and manufacture of a large number of non-standard parts, resulting in high production costs. Summary of the Invention

[0003] Based on this, it is necessary to provide a multi-power transmission system to address the problem of high production costs.

[0004] The present application provides a multi-power transmission system, which includes:

[0005] A conveying bed, wherein the conveying bed has a conveying direction and is provided with rotatable supporting wheel sets along sides of the conveying bed parallel to the conveying direction;

[0006] a first driver, the first driver being disposed on the conveying bed and extending along the conveying direction;

[0007] A conveying trolley, wherein a magnetic member is provided at the bottom of the conveying trolley, the conveying trolley is disposed on a conveying bed, and the bottom of the conveying trolley is in rolling contact with the supporting wheel assembly, the first driver cooperates with the magnetic member to generate a driving force, and the driving force is used to drive the conveying trolley to run at a first speed along the conveying direction; and

[0008] The second driver is arranged on the conveying bed and connected to the supporting wheel group. The second driver is used to drive the supporting wheel group to rotate so that the supporting wheel group drives the conveying trolley to run at a second speed along the conveying direction; wherein the first speed is greater than the second speed.

[0009] In this solution, the first speed is greater than the second speed, and the first speed can be determined as high speed or ultra-high speed, and the second speed can be determined as normal speed or low speed; when the multi-power conveying system is working, when the conveying trolley needs to run at high speed or ultra-high speed to achieve efficient delivery of the workpiece to the target workstation, the second drive remains in a stopped state, and only the first drive is controlled to start working. The first drive cooperates with the magnetic parts installed at the bottom of the conveying trolley to generate driving force, and the driving force can drive the conveying trolley to run at high speed or ultra-high speed on the conveying bed along the conveying direction; when the conveying trolley has delivered the workpiece and returns empty, the conveying trolley only needs to run at normal speed or low speed. At this time, the first drive can be controlled to remain stopped, and the second drive can be controlled to start. The second drive drives the support wheel group to actively rotate, so that the support wheel group uses friction to drive the conveying trolley to return in the opposite direction of the conveying direction on the conveying bed. That is, the conveyor bed of this solution is equipped with two sets of power equipment, high-speed and low-speed, which can meet the requirements of different time rhythms when the conveyor trolley transports workpieces and when the empty trolley returns, and realize the integration of two power equipment on the same conveyor line.

[0044] See Figure 1 and Figure 2 , is a multi-power conveying system 100 shown in an embodiment of the present application, which includes a conveying bed 10, a first drive 30, a conveying trolley 40 and a second drive 50.

[0045] The conveying bed 10 is a long strip structure, which can be an integrated frame structure or a multi-section structure composed of multiple frame bodies. Figure 2 The S arrow in the figure points to the right), for example, the conveying direction in this application is the length direction of the conveying bed 10; the so-called conveying direction refers to the direction in which the conveying trolley 40 conveys the workpiece on the conveying bed 10.

[0046] The conveying bed 10 is provided with rotatable supporting wheel sets 20 along the sides parallel to the conveying direction.

[0047] The first actuator 30 is mounted on the conveyor bed 10 and extends along the conveying direction. For example, the first actuator 30 utilizes a linear motor (also known as a linear motor). When energized, the linear motor generates a magnetic force between the linear motor and the magnetic element 41. This magnetic force acts as the driving force, magnetically driving the conveyor trolley 40. Because this drive method produces minimal (or no) frictional resistance, it enables the conveyor trolley 40 to operate at high or ultra-high speeds. As can be understood, the first actuator 30 and the magnetic element 41 together constitute a magnetic levitation conveying system.

[0048] Considering that the size of the linear motor is much smaller than that of the conveyor bed 10, multiple linear motors need to be installed simultaneously. For example, the top surface of the conveyor bed 10 is recessed with a long, rectangular mounting groove along the conveying direction, and multiple linear motors are sequentially inserted into the mounting groove along the length of the groove, thereby achieving continuous driving of the conveyor trolley 40.

[0049] Please continue reading Figure 2 and Figure 10 A magnetic part 41 is provided at the bottom of the conveying trolley 40. The conveying trolley 40 is arranged on the conveying bed 10, and the bottom of the conveying trolley 40 is in rolling contact with the support wheel group 20. The first driver 30 cooperates with the magnetic part 41 to generate a driving force, and the driving force is used to drive the conveying trolley 40 to run at a first speed along the conveying direction; the second driver 50 is provided on the conveying bed 10 and connected to the support wheel group 20. The second driver 50 is used to drive the support wheel group 20 to rotate, so that the support wheel group 20 drives the conveying trolley 40 to run at a second speed along the conveying direction; wherein the first speed is greater than the second speed.

[0050] It is necessary to explain that in this solution, the first speed is greater than the second speed. The first speed can be determined as high speed or ultra-high speed, and the second speed can be determined as normal speed or low speed.

[0051] When the multi-power conveying system 100 is working, when the conveying trolley 40 needs to run at high speed or ultra-high speed to achieve efficient delivery of the workpiece to the target workstation, the second driver 50 remains in a stopped state, and only the first driver 30 is controlled to start working. The first driver 30 cooperates with the magnetic part 41 installed at the bottom of the conveying trolley 40 to generate a driving force, and the driving force can drive the conveying trolley 40 to run at high speed or ultra-high speed along the conveying direction on the conveying bed 10; when the conveying trolley 40 has delivered the workpiece and returns empty, the conveying trolley 40 only needs to run at normal speed or low speed. At this time, the first driver 30 can be controlled to remain stopped, and the second driver 50 can be controlled to start. The second driver 50 drives the support wheel group 20 to rotate actively, so that the support wheel group 20 uses friction to drive the conveying trolley 40 to return in the opposite direction of the conveying direction on the conveying bed 10. That is, the conveying bed 10 of this solution is equipped with two sets of power equipment, high-speed and low-speed, which can meet the requirements of different time rhythms when the conveying trolley 40 conveys workpieces and when the empty car returns, and realize the integration of two power equipment on the same conveying line body, and there is no need to install non-standard parts, saving the design and manufacturing of non-standard parts, thereby significantly reducing the production cost of the conveying system.

[0052] For example, the second driver 50 includes a motor, a reducer, and a transmission assembly. The motor is connected to the transmission assembly via the reducer, and the transmission assembly is connected to the support wheel assembly 20, so that the rotational drive output by the motor can be transmitted to the support wheel assembly 20 to drive the support wheel assembly 20 to rotate. Alternatively, the transmission assembly can be any one of a pulley mechanism, a sprocket mechanism, etc., and can be selected according to actual needs.

[0053] Please continue reading Figure 2 In addition to the above-described embodiment, the multi-powered conveyor system 100 further includes a plurality of anchors 90a, which are connected to opposite sides of the conveyor bed 10 along the conveying direction. Thus, the conveyor bed 10 can be mounted and fixed to the floor of the workplace via the anchors 90a, ensuring stable and reliable operation of the multi-powered conveyor system 100.

[0054] For example, the foot 90a is fixed to the ground of the work site by bolt installation.

[0055] Please continue reading Figure 2 In one embodiment, the support wheel group 20 includes a plurality of Z-direction support wheels 21, at least part of the circumferential surface of the Z-direction support wheel 21 protrudes from the upper surface of the conveying bed 10, and the plurality of Z-direction support wheels 21 are respectively arranged on two opposite sides of the conveying bed 10 parallel to the conveying direction, and the plurality of Z-direction support wheels 21 on each side are arranged in a row along the conveying direction. The bottom of the conveying trolley 40 is provided with two guide rails 42 arranged side by side, and the guide rails 42 are in rolling contact with the corresponding row of Z-direction support wheels 21.

[0056] The multi-power conveying system 100 also includes two rows of Y-direction guide wheels 60, which are respectively arranged on opposite sides of the first driver 30 and extend along the conveying direction. The two rows of Y-direction guide wheels 60 are set between the two guide rails 42 and in rolling contact with the guide rails 42.

[0057] Two rows of Z-direction support wheels 21 support the two guide rails 42, ensuring that the transport trolley 40 is subjected to stable force and safe operation at high speeds. Furthermore, two rows of Y-direction guide wheels 60, which respectively roll in contact with the two guide rails 42, provide Y-direction positioning and guidance for the transport trolley 40 during movement, ensuring a stable position and posture of the transport trolley 40 and improving operational accuracy.

[0058] Please continue reading Figure 2 and Figure 3 In addition, based on any of the above embodiments, the multi-powered conveyor system 100 further includes a Y-direction positioning assembly 70. The Y-direction positioning assembly 70 is disposed on a side of the conveyor bed 10 parallel to the conveying direction. The Y-direction positioning assembly 70 includes two Y-direction positioning wheels 71 spaced apart and perpendicular to the conveying direction, with the guide rail 42 passing through the gap between the two Y-direction positioning wheels 71. Specifically, the gap between the two Y-direction positioning wheels 71 is slightly smaller than the width of the guide rail 42. This ensures that both Y-direction positioning wheels 71 can reliably press against both widthwise sides of the guide rail 42, thereby achieving better Y-direction positioning of the conveyor trolley 40.

[0059] Please continue reading Figure 2 as well as Figures 4 to 6 Furthermore, in another embodiment, the multi-power conveying system 100 also includes a Z-direction positioning assembly 80, the Z-direction positioning assembly 80 includes a Z-direction positioning cylinder 81, a transmission seat 82, a mounting seat 83 and a Z-direction positioning wheel 84, the mounting seat 83 and the Z-direction positioning cylinder 81 are respectively arranged on the conveying bed 10, the Z-direction positioning wheel 84 is rotatably arranged on the transmission seat 82, the mounting seat 83 is provided with an oblique slide groove 831, the wheel axle of the Z-direction positioning wheel 84 is slidably inserted in the oblique slide groove 831, and the transmission seat 82 is connected to the piston rod of the Z-direction positioning cylinder 81.

[0060] The inclined slide groove 831 has a first end 831a and a second end 831b located in the length direction. The height of the first end 831a is lower than the height of the second end 831b. When the Z-direction positioning wheel 84 is at the first end 831a, it remains in the avoidance position. The Z-direction positioning wheel 84 is clearance-matched with the guide rail 42. When the Z-direction positioning wheel 84 is at the second end 831b, it remains in the supporting position. The Z-direction positioning wheel 84 abuts against the guide rail 42 to lift the conveying trolley 40.

[0061] It is easy to understand that when the conveying trolley 40 is operating normally on the conveying bed 10, the Z-direction positioning cylinder 81 drives the Z-direction positioning wheel 84 to retract and maintain it at the first end 831a position of the inclined slide 831, so that the Z-direction positioning wheel 84 avoids the conveying trolley 40 and avoids interfering with the conveying trolley 40. When the conveying trolley 40 reaches the target workstation, the Z-direction positioning cylinder 81 quickly drives the transmission seat 82 to extend, and the transmission seat 82 pushes the Z-direction positioning wheel 84 to slide from the first end 831a to the second end 831b, so that the Z-direction positioning wheel 84 abuts the guide rail 42 and lifts the conveying trolley 40 to a certain height. At this time, the contact level of the Z-direction positioning wheel 84 and the guide rail 42 is higher than the contact level of the Z-direction support wheel 21 and the guide rail 42, so that the conveying trolley 40 loses the driving force to move along the conveying direction, thereby achieving the Z-direction positioning of the conveying trolley 40 and ensuring that the conveying trolley 40 accurately stops at the target workstation. When the process in the target workstation is completed, the Z-direction positioning cylinder 81 drives the Z-direction positioning wheel 84 to reset to the first end 831a, the Z-direction positioning wheel 84 disengages from the guide rail 42, and the conveying trolley 40 descends and resets to the Z-direction support wheel 21, and the conveying trolley 40 can move away from the current target workstation.

[0062] Furthermore, the Z-direction positioning assembly 80 further includes a roller 85, which is disposed at the end of the axle of the Z-direction positioning wheel 84 and is rollably disposed within the oblique groove 831. As the roller 85 rolls within the oblique groove 831, the sliding friction between the axle of the Z-direction positioning wheel 84 and the wall of the oblique groove 831 is converted to rolling friction, thereby reducing frictional resistance. This helps improve the response speed and smoothness of movement of the Z-direction positioning wheel 84, while also reducing wear on the axle and the oblique groove 831, thereby increasing component service life.

[0063] Please continue reading Figure 2 as well as Figure 9 and Figure 10 In addition, based on any of the above embodiments, the conveying trolley 40 also includes a vehicle body 43, a connecting pin 44 and a carrying rod 45. The carrying rod 45 is connected to the bottom of the vehicle body 43 by the connecting pin 44 so as to be liftable and floating. The magnetic member 41 is arranged on the carrying rod 45. The conveying bed 10 is also provided with a magnetic support wheel 40a. The magnetic support wheel 40a is arranged on opposite sides of the first driver 30, and the magnetic support wheel 40a is in rolling contact with the carrying rod 45.

[0064] The vehicle body 43 is a frame structure formed by welding or assembling metal components made of materials such as stainless steel. It has a simple structure and low manufacturing cost, while also having high structural strength, durability, and reliability. The vehicle body 43 also has a through hole, the diameter of which is larger than the diameter of the connecting pin 44. The connecting pin 44 is inserted into the through hole and has axial freedom of movement. At the same time, there is a gap between the carrier rod 45 and the bottom surface of the vehicle body 43, so that the carrier rod 45 can obtain the ability to rise and fall relative to the vehicle body 43. Under this structural design, when the conveying trolley 40 is lifted or lowered by the Z-positioning assembly 80, the carrier rod 45 can always be supported by the magnetic support wheel 40a, so that the magnetic component 41 and the first driver 30 always maintain a certain distance, ensuring that the first driver 30 can cooperate with the magnetic component 41 to generate driving force, while avoiding friction and wear caused by contact between the two.

[0065] Please continue reading Figure 2 as well as Figure 7 and Figure 8 In another embodiment, a positioning block 46 is further provided at the bottom of the vehicle body 43, and the positioning block 46 has a positioning hole 461. The multi-power conveying system 100 also includes an X-direction positioning assembly 90, which is provided on the side of the conveying bed 10. The X-direction positioning assembly 90 includes a telescopic drive unit and an X-direction positioning wheel 91. The telescopic drive unit is connected to the X-direction positioning wheel 91 and is used to drive the X-direction positioning wheel 91 to extend into the positioning hole 461. This enables the conveying trolley 40 to be positioned in the X direction.

[0066] The X-axis positioning assembly 90 , the Y-axis positioning assembly 70 and the Z-axis positioning assembly 80 of this solution cooperate with each other to ensure high positioning accuracy and high repeatability of the transport trolley 40 .

[0067] In one embodiment, the X-axis positioning assembly 90 includes a mounting plate 92, a cylinder base 93, a telescopic cylinder 94, and a drive pin 95. The mounting plate 92 is mounted on the conveyor bed 10, and the cylinder base 93 is mounted on the mounting plate 92. The cylinder base 93 has a slide hole 931 formed therein. The telescopic cylinder 94 is connected to the cylinder base 93. The drive pin 95 is connected to the piston rod of the telescopic cylinder 94 and slidably extends through the slide hole 931. The X-axis positioning wheel 91 is connected to the end of the drive pin 95 away from the telescopic cylinder 94. During operation, the conveyor trolley 40 operates normally on the conveyor bed 10, the telescopic cylinder 94 remains retracted, and the X-axis positioning wheel 91 is retracted into the slide hole 931 to avoid interference with the conveyor trolley 40. When the transport trolley 40 needs to be positioned in the target workstation, the telescopic cylinder 94 drives the transmission pin 95 to extend, and the transmission pin 95 pushes the X-direction positioning wheel 91 to extend from the slide hole 931 and resist the side of the transport trolley 40, thereby achieving the X-direction positioning of the transport trolley 40.

[0068] Optionally, the X-axis positioning wheel 91 is a rubber wheel, which can reduce the collision force with the conveying trolley 40, prevent the X-axis positioning assembly 90 and the conveying trolley 40 from being damaged by collision, and also reduce the noise generated by the collision, making the multi-power conveying system 100 run more quietly.

[0069] Furthermore, the X-axis positioning assembly 90 further includes a bushing 96, which is sleeved within the slide hole 931, and the drive pin 95 is slidably inserted into the bushing 96. The bushing 96 is specifically an oil-free bushing 96, which guides the telescopic movement of the drive pin 95 and provides self-lubrication, thereby ensuring more stable and reliable positioning of the drive pin 95 and the X-axis positioning wheel 91.

[0070] Furthermore, the X-axis positioning assembly 90 includes a stopper 97, which is mounted on the cylinder base 93. The drive pin 95 is provided with a stopper surface 951, which engages with the stopper 97. The engagement of the stopper 97 with the stopper surface 951 prevents the drive pin 95 from rotating freely within the bushing 96, thereby ensuring that the X-axis positioning wheel 91 moves along a predetermined telescopic linear path, thereby accurately inserting into the positioning hole 461.
