Description

Technical Field

[0001] This application relates to the field of conveying system technology, specifically to a conveying device and a cross roller conveyor system. Background Technology

[0002] During the processing and production of workpieces, it is often necessary to transport workpieces between different workstations, and the current conveying methods are mostly linear conveying. However, considering the needs and limitations of some workpieces with many processes, factory manufacturing processes, and factory space, many workpieces also need to be transported on conveyor lines in different directions. Therefore, it is necessary to consider setting up conveying devices between adjacent conveyor lines in different directions to achieve the lifting and lowering of workpieces between conveyor lines in different directions.

[0003] Most current conveying devices use a rotary mechanism to achieve workpiece reversal, where the conveyor itself rotates to change the direction of the workpiece, completing the transfer of the workpiece from one conveyor line to another. However, rotary conveying devices have a heavy load, and heavy, bulky components can easily damage the rotary mechanism. Furthermore, placing a rotary conveyor between two conveyor lines requires a certain amount of space for rotation and turning, which places certain spatial requirements on the device. The large space occupied during rotation also increases the cost of site occupancy. Utility Model Content

[0020] The beneficial effects of the embodiments of this application are as follows:

[0021] The conveying device and cross roller conveyor system provided in this application embodiment are arranged such that the conveying device is placed between the beginning and end of two conveyor lines for docking. The two conveyor lines are defined as the first conveyor line and the second conveyor line, respectively. Since the conveying directions of the first conveyor line and the second conveyor line are set at an angle, the workpiece is first conveyed on the first conveyor line. The workpiece is then transferred from the first conveyor line to the conveying mechanism of this conveying device. Then the workpiece on the conveying mechanism is transferred to the second conveyor line. Thus, the conveying device can complete the reversing conveying of the workpiece from the first conveyor line to the second conveyor line.

[0022] The conveying device and cross roller conveyor system provided in this application utilize the lifting motion of a lifting mechanism to allow the conveying mechanism to connect with conveyor lines at different heights, completing the transfer of workpieces between conveyor lines of different heights and conveying directions. This eliminates the need for the conveying device itself to rotate, avoiding the problem of large volume caused by the large turning radius in existing technologies. It can also be applied to reversing conveying between conveyor lines at the same height. In this case, the lifting mechanism does not need to perform lifting motion; the connection between different conveyor lines can be completed solely through the conveying mechanism, achieving reversing conveying. Compared to existing workpiece reversing conveying methods that rely on rotation, the conveying device of this application achieves workpiece reversing flow with high motion accuracy, fast response speed, high safety, and ease of maintenance. Furthermore, the overall size of the conveying device is small, occupying little space and requiring less site restriction, thus reducing manufacturing costs. Attached Figure Description

Detailed Implementation

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0035] In the description of this application, it should be noted that the terms "inner," "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the workpiece is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] It should also be noted that, unless otherwise explicitly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] Please refer to Figure 1 , Figure 2 As shown, this application embodiment provides a conveying device 100, which is used to be disposed between the beginning and end of two conveying lines, the conveying directions of the two conveying lines being arranged at an angle.

[0038] The conveying device 100 includes: a base 1, a support plate 2 disposed on the base 1, and a conveying mechanism 5 disposed on the support plate 2. A lifting mechanism is also provided between the support plate 2 and the base 1. The lifting mechanism drives the support plate 2 to rise and fall, so as to connect the conveying mechanism 5 on the support plate 2 with different conveying lines, so as to transfer the workpiece from one conveying line to another conveying line through the conveying mechanism 5.

[0039] A base 1 is fixedly installed, and a support plate 2 is mounted on the base 1. The support plate 2 is spaced apart from and parallel to the base 1. A conveying mechanism 5 is mounted on the support plate 2 for conveying workpieces. A lifting mechanism is installed between the base 1 and the support plate 2. The lifting mechanism can drive the support plate 2 to rise and fall, thereby causing the conveying mechanism 5 on the support plate 2 to rise and fall, so as to connect with conveyor lines at different heights for workpiece conveying. Alternatively, the lifting mechanism can be deactivated, in which case the connection with conveyor lines at the same height can be completed solely through the conveying mechanism 5.

[0040] Taking conveyor lines at different heights as an example, in use, the conveying device 100 of this application is placed between the beginning and end of two conveyor lines for docking. The two conveyor lines are defined as the first conveyor line 200 and the second conveyor line 300, respectively. Since the conveying directions of the first conveyor line 200 and the second conveyor line 300 are set at an angle and there is a height difference between the first conveyor line 200 and the second conveyor line 300, the workpiece is first conveyed on the first conveyor line 200, so that the conveying mechanism 5 of the conveying device 100 rises and falls along the height direction to be coplanar with the first conveyor line 200. The workpiece is transferred from the first conveyor line 200 to the conveying mechanism 5 of the conveying device 100. Then the conveying mechanism 5 follows the carrier plate 2 and rises and falls again to be coplanar with the second conveyor line 300. At this time, the workpiece on the conveying mechanism 5 is transferred to the second conveyor line 300. Thus, the conveying device 100 can complete the reversing conveying of the workpiece from the first conveyor line 200 to the second conveyor line 300.

[0041] The conveying device 100 provided in this application embodiment utilizes the lifting motion of the lifting mechanism to enable the conveying mechanism 5 to connect with conveyor lines at different heights, completing the transfer of workpieces between conveyor lines of different heights and conveying directions. This eliminates the need for the conveying device 100 itself to rotate, avoiding the problem of large volume caused by the large turning radius in existing technologies. It can also be applied to reversing the flow of workpieces on conveyor lines at the same height. In this case, the lifting mechanism does not need to perform lifting motion; the connection between different conveyor lines can be completed solely through the conveying mechanism 5, achieving reversing conveying. Compared to existing methods that use rotation for workpiece reversal, the conveying device 100 of this application achieves workpiece reversal with high motion accuracy, fast response speed, high safety, and ease of maintenance. Furthermore, the conveying device 100 has a small overall size, occupies little space, has fewer site requirements, and correspondingly reduces manufacturing costs.

[0042] Specifically, in the embodiments of this application, reference is made to Figure 1 , Figure 6 As shown, the lifting mechanism includes a linkage assembly 3 and a rotating assembly 4 connected to the linkage assembly 3. The linkage assembly 3 is hinged to the bearing plate 2 and the base 1 respectively. The rotating assembly 4 drives the linkage assembly 3 to move, so that the bearing plate 2 is raised or lowered.

[0043] In this application, the base 1, connecting rod assembly 3, and bearing plate 2 form a connecting rod structure. The rotating assembly 4 provides the driving force for the movement of the connecting rod assembly 3, which in turn drives the connecting rod assembly 3 to move, thereby raising and lowering the bearing plate 2. Compared with other lifting structures such as lead screws, nuts, or push rods, this application achieves the raising and lowering of the bearing plate 2 through the connecting rod assembly 3, resulting in high power transmission efficiency, high motion reliability, and a simple, compact structure that occupies less space.

[0044] A linkage assembly 3 of this application forms a hinged position between the base 1 and the support plate 2. The linkage assembly 3 includes at least one link. When only one link is included, the link is hinged to both the base 1 and the support plate 2. This arrangement, where the base 1 and the support plate 2 are connected by a single link at a hinged position, simplifies the overall structure and makes it easy to implement. In this case, the link can be hinged at the center position between the base 1 and the support plate 2, forming a three-bar linkage with the base 1 and the support plate 2.

[0045] In addition, the connecting rod can generally be hinged to the bearing plate 2 and the base 1 at its two ends respectively. In addition, the connecting rod can also be hinged to the bearing plate 2 and the base 1 at other positions other than the ends. For example, the connecting rod can be hinged to the bearing plate 2 and the base 1 at two positions in the middle, without specific restrictions.

[0046] A linkage assembly 3 may also include two or more links, meaning that a hinge position may include two or more links, which can be connected sequentially. The first and last links are respectively hinged to the support plate 2 and the base 1. For example, two links are provided at the same hinge position between the base 1 and the support plate 2, and the two links are hinged to each other. One link is hinged to the base 1, and the other link is also hinged to the support plate 2. When multiple links are provided at one hinge position to connect the support plate 2 and the base 1, it is beneficial to improve the stability of the motion, improve the motion performance, and improve the motion accuracy.

[0047] In the example of this application, a linkage assembly 3 includes a link. There are at least two sets of linkage assemblies 3, and the at least two sets of linkage assemblies 3 are arranged along the conveying direction F of the conveying mechanism 5. This application has two sets of linkage assemblies 3, and the two sets of linkage assemblies 3 respectively include a first link 31 and a second link 32. The first link 31 and the second link 32 are respectively hinged to the bearing plate 2 and the base 1.

[0048] like Figure 1As shown, the first link 31 and the second link 32 of this application are arranged along the conveying direction F of the conveying mechanism 5, and the first link 31 and the second link 32 are arranged parallel to each other, which can keep the bearing plate 2 in a horizontal state during the lifting and lowering movement.

[0049] Of course, the first link 31 and the second link 32 can also be set diagonally or at an angle at the bottom of the bearing plate 2, which will also have the effect of driving the bearing plate 2 to rise and fall. The arrangement of the first link 31 and the second link 32 is not specifically limited.

[0050] Furthermore, in this application, there are two first connecting rods 31 and two second connecting rods 32. The two first connecting rods 31 are symmetrically arranged at both ends of the bottom of the support plate 2 along the first direction F1, and the two second connecting rods 32 are symmetrically arranged at both ends of the bottom of the support plate 2 along the first direction F1, which is perpendicular to the conveying direction F of the conveying mechanism 5. In this way, the two first connecting rods 31 and the two second connecting rods 32 form four hinge positions between the support plate 2 and the base 1, and are symmetrically distributed at the four corner positions of the bottom of the support plate 2, which can keep the support plate 2 in balance during lifting and lowering. The first connecting rods 31, the second connecting rods 32, the support plate 2 and the base 1 on the same side along the conveying direction F of the conveying mechanism 5 form a four-bar linkage, and the first connecting rods 31, the second connecting rods 32, the support plate 2 and the base 1 on the other side form another four-bar linkage, thus forming two four-bar linkages between the support plate 2 and the base 1.

[0051] The two four-bar linkages enhance the load-bearing capacity of the support plate 2, maintain its motion stability, and reduce component wear caused by uneven stress. This allows the support plate 2 to meet the lifting and conveying requirements of heavy and large-volume workpieces. Furthermore, the synchronized operation of the two four-bar linkages further ensures the balance and reliability of the support plate 2's motion.

[0052] There are two sets of linkage assemblies 3 on the same side as the conveying direction F of the aforementioned conveying mechanism 5, namely a first linkage 31 and a second linkage 32. The first linkage 31, the second linkage 32, the bearing plate 2 and the base 1 form a four-bar linkage mechanism. When there are more than two sets of linkage assemblies 3, five-bar linkage, six-bar linkage and so on can be formed to adapt to different scenario requirements.

[0053] For example, the rotating assembly 4 used to drive the linkage assembly 3 is located at the hinge end 6 between the first link 31 and the base 1. The rotating assembly 4 includes a rotating shaft disposed along a first direction F1 and a first driving member connected to the rotating shaft. The rotating shaft is connected to the link, and the first driving member drives the rotating shaft to rotate, thereby moving the link.

[0054] The first driving component provides driving force to the rotating shaft to drive the rotating shaft to rotate, and the rotating shaft then drives the connecting rod to move.

[0055] In the embodiments of this application, the linkage assembly 3 has two sets, including a first linkage 31 and a second linkage 32. Correspondingly, the rotating shaft includes a first rotating shaft 41 and a second rotating shaft 42. The first rotating shaft 41 and the second rotating shaft 42 are arranged in parallel. A first driving member is connected to the first rotating shaft 41. The first rotating shaft 41 is connected to the first linkage 31 and drives the first linkage 31 to move. The second rotating shaft 42 is connected to the second linkage 32 and drives the second linkage 32 to move.

[0056] Both the first rotating shaft 41 and the second rotating shaft 42 are arranged along the first direction F1. One end of the first rotating shaft 41 is connected to the first driving member, and the other end passes through the two first connecting rods 31 in the first direction F1 in sequence, and is anti-rotationally engaged with the hinge end 6 of the two first connecting rods 31 and the base 1. The first rotating shaft 41 drives the two first connecting rods 31 to move synchronously.

[0057] Similarly, the second rotating shaft 42 passes through the two second connecting rods 32 in the first direction F1 in sequence, and engages with the hinge end 6 of the two second connecting rods 32 and the base 1 to prevent rotation, thereby driving the two second connecting rods 32 to move synchronously.

[0058] Since the first driving component provides driving force to the first rotating shaft 41, the second connecting rod 32 and the second rotating shaft 42 can move under the drive of the first connecting rod 31 and the bearing plate 2. Therefore, the second rotating shaft 42 does not need to be connected to an additional driving component. The arrangement of the second rotating shaft 42 makes the movement of the second connecting rod 32 easier. Through the cooperation of the first rotating shaft 41 and the second rotating shaft 42, this application can also improve the overall strength of the conveying device 100 and improve the safety of device operation.

[0059] For example, a hinge plate is also provided at the bottom of the support plate 2 corresponding to the positions of the first link 31 and the second link 32. The ends of the first link 31 and the second link 32 connected to the support plate 2 are provided with U-shaped openings that are adapted to the hinge plates. The first link 31 and the second link 32 are inserted into the corresponding hinge plates through their respective U-shaped openings and are rotatably mounted on the hinge plates through the hinge shaft, so as to realize the hinge connection between the first link 31 and the second link 32 and the support plate 2 respectively.

[0060] Based on this, a third link 43 and a fourth link 44 are respectively provided at the ends of the first rotating shaft 41 and the second rotating shaft 42 away from the first driving member, and at least a fifth link 45 is provided between the third link 43 and the fourth link 44 to connect the third link 43 and the fourth link 44.

[0061] A third link 43 is disposed at the end of the first rotating shaft 41 away from the first driving member, and a fourth link 44 is disposed at the end of the second rotating shaft 42 away from the first driving member. For example, both the third link 43 and the fourth link 44 are located on the outer side of the base 1 away from the first driving member. The third link 43 and the two first links 31 are all disposed on the first rotating shaft 41, and the third link 43 and the two first links 31 are parallel to each other along the first direction F1; the fourth link 44 and the two second links 32 are all disposed on the second rotating shaft 42, and the fourth link 44 and the two second links 32 are parallel to each other along the first direction F1.

[0062] The third link 43 and the fourth link 44 are hinged together by the fifth link 45, so that the third link 43, the fourth link 44, the fifth link 45 and the base 1 form another four-bar linkage. Similarly, in addition to the fifth link 45, other links can be added in sequence to connect the third link 43 and the fourth link 44, thus forming a five-bar linkage, a six-bar linkage, etc., which will not be elaborated here.

[0063] The two sets of four-bar linkages formed by the two first links 31, the two second links 32, the bearing plate 2 and the base 1, and the other four-bar linkage formed by the third link 43, the fourth link 44, the fifth link 45 and the base 1, make the bearing plate 2 and the base 1 form a linkage combination of interconnected multi-link mechanisms. The setting of the multi-link mechanism optimizes the force transmission path between the base 1 and the bearing plate 2, making the mechanical performance of the entire transmission device 100 more reasonable when the bearing plate 2 is lifted and lowered, reducing unnecessary stress concentration, improving the stability of the lifting and lowering movement, and also improving the load capacity of the bearing plate 2.

[0064] In addition, in the example of this application, the base 1 may include a first base 11 and a second base 12. The first base 11 and the second base 12 are coplanar and spaced apart along the first direction F1, wherein the bearing plate 2 and the connecting rod assembly 3 are both disposed on the first base 11. The bottom of the second base 12 is provided with a support leg 13 to support the second base 12. A rotating seat 48 is disposed on the second base 12 at a position corresponding to the first connecting rod 31. The first rotating shaft 41 is rotatably mounted on the rotating seat 48 through a bearing, and the hinge end 6 of the first connecting rod 31 is anti-rotated and mounted at the corresponding position of the first rotating shaft 41 through an anti-rotation key.

[0065] The first driving component is mounted on the second base 12 and is used to drive the first rotating shaft 41 to rotate. In some embodiments, the first driving component includes a driving cylinder 46, which includes a cylinder body 461 and a piston rod 462, and the piston rod 462 is connected to the first rotating shaft 41. The driving cylinder 46 can be a pneumatic cylinder or a hydraulic cylinder.

[0066] like Figure 1In the middle, the drive cylinder 46 is located on the second base 12. Two mounting seats 481 are symmetrically arranged on both sides of the cylinder body 461 along the axial direction. The cylinder body 461 is rotatably engaged with the corresponding mounting seat 481 through the hinge shaft, so that the cylinder body 461 is hinged to the second base 12.

[0067] In addition, the piston rod 462 and the first rotating shaft 41 are hinged by the sixth link 47. The cylinder 461 drives the piston rod 462 to extend and retract, which in turn drives the first rotating shaft 41 to rotate through the sixth link 47, thereby realizing the lifting and lowering of the bearing plate 2.

[0068] The second base 12 and the first base 11 are spaced apart, so that the first driving component located on the second base 12 can be moved away from the support plate 2. When it is necessary to transport high-temperature workpieces, the high-temperature workpieces transported by the conveying mechanism 5 on the support plate 2 can be prevented from damaging the first driving component and the corresponding circuit, thereby ensuring the effective and safe operation of the device.

[0069] Furthermore, since the first driving component is a certain distance from the bearing plate 2, the first rotating shaft 41 can be segmented, with adjacent segments connected by couplings for transmission.

[0070] In other embodiments, the first driving element may further include a first driving motor connected to a first rotating shaft 41. A speed reducer may be provided between the first driving motor and the first rotating shaft 41 to match the speed ratio between the first driving motor and the first rotating shaft 41.

[0071] The conveying mechanism 5 includes a second driving member 53, a driving wheel connected to the second driving member 53, and at least one driven wheel connected to the driving wheel via a transmission chain 52. The driving wheel and the driven wheel form a wheel set 51. The transmission chain 52 is arranged along the conveying direction F of the conveying mechanism 5, and the workpiece is conveyed through the transmission chain 52.

[0072] This application uses a transmission chain 52 to transport workpieces, which provides strong power transmission and ensures effective workpiece transport. Furthermore, the transmission chain 52 is wear-resistant and has a long service life, which can reduce the failure rate of the transmission.

[0073] Specifically, such as Figure 3 , Figure 4 As shown, the second driving component 53 may include a second driving motor 532, and a third rotating shaft 531 is provided between the second driving motor 532 and the driving wheel. The third rotating shaft 531 is engaged with the driving wheel to prevent rotation. The second driving motor 532 drives the third rotating shaft 531 to rotate, thereby driving the driving wheel to rotate.

[0074] For example, the second drive motor 532 is fixed on the second base 12 by the motor mount 533. The second drive motor 532 and the drive cylinder 46 are arranged at intervals on the second base 12. The second drive motor 532 is also set away from the support plate 2 so as to avoid damage to the second drive motor 532 when the conveying mechanism 5 on the support plate 2 conveys high-temperature workpieces, thereby improving the service life of the conveying device 100.

[0075] like Figure 1 , Figure 6 As shown, a telescopic coupling 534 is also provided between the second drive motor 532 and the third rotating shaft 531, and a universal joint 535 is provided between the telescopic coupling 534 and the drive motor and the third rotating shaft 531.

[0076] The telescopic coupling 534 allows for axial displacement or extension in the first direction F1, while the universal joint 535 can be used at positions where the direction of the transmission shaft needs to be changed. Through the cooperation of the telescopic coupling 534 and the universal joint 535, this application can adapt to the positional changes between the second drive motor 532 and the third rotating shaft 531 after the bearing plate 2 is raised or lowered, ensuring that the second drive motor 532 can still effectively drive the third rotating shaft 531 to rotate, thereby improving the applicability of the device before and after raising or lowering.

[0077] like Figure 5 As shown, the third rotating shaft 531 can be segmented, including a first rod 536 and a second rod 537, which are connected by a telescopic coupling 534.

[0078] In other embodiments, when the workpiece is conveyed to meet the usage requirements, the second drive motor 532 can be directly mounted on the support plate 2, and the output end of the second drive motor 532 can be engaged with the third rotating shaft 531 to prevent rotation.

[0079] In addition, such as Figure 5 As shown, at the bottom of the bearing plate 2 corresponding to the position of the third rotating shaft 531, two support plates 520 are arranged at intervals along the first direction F1. The third rotating shaft 531 passes through the two support plates 520 in sequence and rotates with the corresponding support plate 520 through the support bearing 519 to support the third rotating shaft 531.

[0080] On the other hand, the wheel set 51 formed by the aforementioned driving wheel and driven wheel can be driven in the form of a sprocket set. By meshing the sprocket set with the transmission chain 52, it can provide greater friction and transmission efficiency, ensuring that the workpiece is not easy to slip or stop during the transmission process, thus ensuring the smooth progress of the production process.

[0081] Among them, such as Figure 3As shown, the driving wheel includes a first tension sprocket 513, which is engaged with the third rotating shaft 531 to prevent rotation. The driven wheel includes a second tension sprocket 514, a first transmission sprocket 511, and a second transmission sprocket 512. The first tension sprocket 513, the second tension sprocket 514, the first transmission sprocket 511, and the second transmission sprocket 512 are all engaged with the transmission chain 52 for transmission.

[0082] The first drive sprocket 511 is arranged side by side with the first tension sprocket 513 along the second direction F2. The second drive sprocket 512 is arranged side by side with the first drive sprocket 511 along the transmission direction F of the transmission mechanism 5. The first tension sprocket 513, the first drive sprocket 511, and the second drive sprocket 512 are all located on the inner side of the transmission chain 52. The second tension sprocket 514 is located on the outer side of the transmission chain 52 and close to the first tension sprocket 513. The second tension sprocket 514 and the first tension sprocket 513 are staggered along the second direction F2. The transmission direction F, the second direction F2, and the first direction F1 of the transmission mechanism 5 are perpendicular to each other. The second direction F2 is the lifting direction.

[0083] For example, the first drive sprocket 511 and the second drive sprocket 512 are located above the support plate 2 and within the drive chain 52 along the conveying direction F of the conveying mechanism 5. Figure 3 , Figure 4 , Figure 7 As shown, both sides of the first transmission sprocket 511 and the second transmission sprocket 512 along the first direction F1 are provided with first support plates 515. Both the first transmission sprocket 511 and the second transmission sprocket 512 are equipped with anti-rotation sprocket shafts 518. The two ends of the sprocket shafts 518 are rotatably mounted on the corresponding first support plates through rotating bearings 49, thereby realizing the rotation of the first transmission sprocket 511 and the second transmission sprocket 512.

[0084] Multiple second support plates 516 are also spaced between the two first support plates 515. A baffle 517 is fixedly installed on the upper end of the multiple second support plates 516 along the lifting direction. The baffle 517 is set on one side of the transmission chain 52 along the first direction F1. The baffle 517 can prevent the transmission chain 52 from falling off.

[0085] Referring to this application Figure 3The arrangement of the first tension sprocket 513, the second tension sprocket 514, the first transmission sprocket 511, and the second transmission sprocket 512 in this application forms an L-shaped arrangement of the transmission chain 52. This allows the transmission chain 52 to maintain good tension and a stable transmission path under the synchronous cooperation of the four sprockets. Furthermore, the first tension sprocket 513, the first transmission sprocket 511, and the second transmission sprocket 512 are all located on the inner side of the transmission chain 52, while the second tension sprocket 514 is located on the outer side. This internal and external meshing ensures effective support and transmission of the workpiece by the transmission chain 52, and reduces the risk of malfunctions caused by slackness or misalignment of the transmission chain 52 during operation. This improves the operating efficiency of the transmission mechanism 5 and ensures operational stability.

[0086] like Figure 4 As shown in the embodiment of this application, there are two sets of transmission chains 52 and their cooperating wheel sets 51. The two sets of wheel sets 51 and the two sets of transmission chains 52 are arranged along the first direction F1. The two sets of transmission chains 52 are respectively supported on both sides of the bottom of the workpiece, which can stably transfer the workpiece from the first conveyor line 200 to the second conveyor line 300.

[0087] The third rotating shaft 531 passes sequentially through the first tension sprockets 513 of the two sets of sprockets along the first direction F1, and engages with the two first tension sprockets 513 to prevent rotation. In this way, the second drive motor 532 can simultaneously drive the two first tension sprockets 513 to rotate, realizing the synchronous action of the two sets of transmission chains 52. This ensures that the workpiece is subjected to uniform force and runs smoothly during the conveying process, avoiding problems such as workpiece offset or jamming caused by inconsistent conveying speeds on both sides, and improving the working efficiency and reliability of the entire cross roller conveyor system.

[0088] Furthermore, on the circumference of the first transmission sprocket 511, the second transmission sprocket 512, the first tension sprocket 513, and the second tension sprocket 514, two sets of teeth are symmetrically arranged along the axis of the sprockets, and a transmission chain 52 is wound on each set of teeth. In this way, the transmission mechanism 5 on one side along the first direction F1 includes two transmission chains 52. This arrangement can reduce the force on the transmission mechanism 5 on one side and improve the overall load-bearing capacity and safety of the transmission mechanism 5.

[0089] Based on this, please refer to Figure 8As shown in the embodiments of this application, a cross roller conveyor system is also disclosed, including a first conveyor line 200 and a second conveyor line 300, and the aforementioned conveying device 100 connected between the beginning and end of the first conveyor line 200 and the second conveyor line 300. There is a height difference between the first conveyor line 200 and the second conveyor line 300. For example, the conveying directions of the first conveyor line 200 and the second conveyor line 300 are set at 90 degrees. The conveying device 100 is used to lift and transfer the workpiece on the first conveyor line 200 to the second conveyor line 300.

[0090] By moving the support plate 2 on the conveying device 100 up and down along the second direction F2, the workpiece can be transferred from the first conveying line 200 to the second conveying line 300 via the conveying mechanism 5 on the support plate 2.

[0091] The following description uses the first conveyor line 200 and the second conveyor line 300 as roller conveyor lines as an example. The height of the first conveyor line 200 is defined as being higher than the height of the conveying mechanism 5, and the height of the first conveyor line 200 is also higher than the height of the second conveyor line 300.

[0092] In actual operation, the workpiece is first transferred on the first conveyor line 200. The first driving component of this application is activated to raise the support plate 2, which drives the transmission chain 52 of the conveying mechanism 5 on the support plate 2 to rise and insert into the corresponding roller gap at the output end of the first conveyor line 200 until the height of the transmission chain 52 matches the height of the rollers of the first conveyor line 200. The transmission chain 52 and the first conveyor line 200 are coplanar in the height direction, so that the workpiece moves through the first conveyor line 200 to the transmission chain 52 of the conveying mechanism 5.

[0093] Once the workpiece is fully seated on the drive chain 52, it is now above the input end of the second conveyor line 300.

[0094] The first drive component is reversed so that the carrier plate 2 is lowered until the transmission chain 52 and the second conveyor line 300 are at the same height. At this time, the transmission chain 52 and the second conveyor line 300 are coplanar in the height direction. The workpiece is transferred from the transmission chain 52 to the rollers of the second conveyor line 300. The workpiece can continue to be conveyed along the second conveyor line 300, thereby completing the reversing operation of conveying the workpiece from the first conveyor line 200 to the second conveyor line 300.

[0095] The above Figure 8 In the embodiment shown, the first conveyor line 200 and the second conveyor line 300 have a height difference, that is, the first conveyor line 200 and the second conveyor line 300 are at different heights.

[0096] In addition, with Figure 8 Unlike the illustrated embodiments, the transmission device 100 provided in this application can also be applied to... Figure 9As shown in the scenario, the cross roller conveyor system disclosed in this application embodiment further includes a first conveyor line 400 and a second conveyor line 600, and the aforementioned conveying device 100 connected between the first conveyor line 400 and the second conveyor line 600. The conveying device 100 can transfer workpieces from the first conveyor line 400 to the second conveyor line 600. The first conveyor line 400 and the second conveyor line 600 are at the same height, and both can be transferred using the conveying device 100. The first conveyor line 400 and the second conveyor line 600 are generally two mutually perpendicular roller conveyor lines.

[0097] This cross-roller conveyor system has the same structure and beneficial effects as the conveyor 100 in the foregoing embodiments. The structure and beneficial effects of the conveyor 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0098] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
