[0072] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0073] Production lines generally have multiple workstations, and conveying equipment is often required between workstations for transportation. In the prior art, the handover between adjacent conveying equipment is relatively complicated, and even manual handover of conveyed items is required, resulting in low handover efficiency at the handover point, which greatly affects the production cycle and limits the manufacturer's production capacity. Based on this, the present invention provides a composite conveying system to solve the problem of low handover efficiency at the handover point of conveying equipment in the prior art, and has the advantage of high handover efficiency. The specific solution is as follows:

[0074] Reference Figures 1 to 8 As shown, the present invention provides a composite conveying system, specifically referring to Figure 1 As shown, the composite conveying system includes a conveying carrier 10, a first conveying line 20, a second conveying line 30 and an unlocking mechanism 40. The conveying carrier 10 is provided with a first connecting structure 101. The first conveying line 20 includes a displacement component 201 and a first driving mechanism 202 that drives the displacement component 201 to move to convey goods. The displacement component 201 is provided with a second connecting structure 2011, which is detachably connected to the first connecting structure 101 and is in a locked state. One end of the second conveying line 30 is connected to one end of the first conveying line 20, and a connecting position is formed at the connection point. The second conveying line 30 includes a second driving mechanism 301 that drives the conveying carrier 10 to move to convey goods. The unlocking mechanism 40 is used to unlock the first connecting structure 101 and the second connecting structure 2011, driving the first connecting structure 101 and the second connecting structure 2011 to disengage; the unlocking mechanism 40 is arranged on the first conveying line 20 and is located at the end near the connecting position. When the transport carrier 10 is located at the engaging position, the transport carrier 10 contacts the second driving mechanism 301 , and the second driving mechanism 301 drives the transport carrier 10 to enter the second conveying line 30 .

[0075] It should be noted that in this embodiment, according to the actual needs of the workstation, the first conveyor line 20 is set as a high-speed conveyor line and the second conveyor line 30 is a low-speed conveyor line. The connection position is the switching and transition position between the high-speed conveyor line and the low-speed conveyor line.

[0076] For example, in this embodiment, when the conveying system is operating normally, the items to be conveyed are placed on the conveying carrier 10. At this time, the first connecting structure 101 on the conveying carrier 10 is connected to the second connecting structure 2011, and the conveying carrier 10 is in transmission connection with the first driving mechanism 202. The conveying carrier 10 is driven by the first driving mechanism 202 to move on the first conveyor line 20 to convey the goods. When the conveying carrier 10 moves to the engaged position, the unlocking mechanism 40 is operated to disengage the connection between the first connecting structure 101 and the second connecting structure 2011, driving the first connecting structure 101 and the second connecting structure 2011 to disengage. At this time, the conveying carrier 10 is disconnected from the first driving mechanism 202.

[0077] When the conveying carrier 10 is at the connecting position, since the connecting position is located at the connection between the first conveyor line 20 and the second conveyor line 30, and the conveying carrier 10 itself has a certain length value, a part of the conveying carrier 10 has entered the second conveyor line 30, and the conveying carrier 10 is in contact with the second driving mechanism 301 on the second conveyor line 30. When the unlocking mechanism 40 disconnects the transmission connection between the conveying carrier 10 and the first driving mechanism 202, the second driving mechanism 301 is started, which can drive the conveying carrier 10 to enter the second conveyor line 30 and drive the conveying carrier 10 to move on the second conveyor line 30 to transport goods.

[0078] In this embodiment, the coordinated arrangement of the first connecting structure 101, the second connecting structure 2011 and the unlocking mechanism 40 synchronously realizes the transfer and handover of the mobile carrier at the connecting position of the conveying system. By switching the transmission connection state of the conveying carrier 10, the conveying carrier 10 is stably and quickly transferred from the high-speed conveying first conveying line 20 to the low-speed conveying second conveying line 30, which solves the problem of low handover efficiency at the handover point of the conveying equipment in the prior art, has the advantage of higher handover efficiency, and has higher overall practicality.

[0079] Reference Figure 2 as well as Figure 3 As shown, the first conveyor line 20 as a whole includes a first support bracket 203 and a rolling support assembly 204, wherein the rolling support assembly 204 is arranged as a whole along the conveying direction to support the conveying carrier 10. At least two first support brackets 203 are provided, and the first support brackets 203 are arranged on both sides of the rolling support assembly 204 and are arranged at intervals along the length direction of the rolling support assembly 204, and are used as a whole to support the rolling support assembly 204.

[0080] The rolling support assembly 204 includes a mounting plate 2041 and support rollers 2042. The mounting plates 2041 are arranged on both sides of the first conveyor line 20, and the length direction of the mounting plates 2041 is arranged in the same direction as the conveying direction of the first conveyor line 20. The first support bracket 203 is used to fix the mounting plates 2041 and support the mounting plates 2041. There are at least two support rollers 2042, which are rotatably connected to the mounting plates 2041 and are spaced apart along the conveying direction of the first conveyor line 20 to support the conveying carrier 10 in a rolling manner. When the conveying carrier 10 enters the first conveyor line 20, the bottom of the conveying carrier 10 contacts the support rollers 2042. When the conveying carrier 10 is conveyed, the support rollers 2042 roll and support the conveying carrier 10. This support method has the advantage of low friction and can improve the driving efficiency of the first drive mechanism 202.

[0081] Specifically, because the first conveyor line 20 has a relatively long conveying distance as a whole, in this embodiment, the mounting plates 2041 are intermittently arranged to facilitate assembly of the entire first conveyor line 20. The support rollers 2042 are evenly arranged along the length of the mounting plates 2041 and are symmetrically arranged on the two mounting plates 2041.

[0082] Reference Figure 4 As shown, more preferably, in this embodiment, the first conveyor line 20 also includes a first horizontal positioning assembly 205. The first horizontal positioning assembly 205 includes a first positioning roller 2051 and a positioning block 2052, the first positioning roller 2051 is rotatably connected to the mounting plate 2041, and the first positioning roller 2051 is spaced apart along the conveying direction of the first conveyor line 20. Both sides of the conveying carrier 10 are symmetrically fixed with positioning blocks 2052, the first positioning roller 2051 contacts the positioning blocks 2052 correspondingly, and the rotation axis of the first positioning roller 2051 is vertically arranged. Therefore, when the conveying carrier 10 moves on the rolling support assembly 204, the positioning block 2052 will contact the first positioning roller 2051, and the first positioning roller 2051 carries out horizontal positioning guidance to the conveying carrier 10 along the conveying direction of the first conveyor line 20.

[0083] Reference Figures 5 to 7As shown, in one embodiment, the first drive mechanism 202 is further refined. In this embodiment, the first drive mechanism 202 includes a first mounting frame 2021, a first transmission assembly 2022, and a guide assembly 2023. The guide assembly 2023 is arranged along the conveying direction of the first conveyor line 20, and the displacement assembly 201 is slidably connected to the guide assembly 2023. Specifically, in this embodiment, the guide assembly 2023 is a guide rail, and two guide rails are provided. The length directions of the two guide rails are arranged along the conveying direction of the first conveyor line 20, and the two guide rails are also fixedly mounted on the first mounting frame 2021.

[0084] Specifically, in this embodiment, the first transmission assembly 2022 is a belt transmission assembly, and the first transmission assembly 2022 includes a first motor 20221, a transmission belt 20222, a first driving wheel 20223 and four transmission wheels 20224. The first mounting frame 2021 is arranged along the conveying direction of the first conveyor line 20 as a whole, and the first supporting bracket 203 is provided with a rotary arm extending toward the middle. The first mounting frame 2021 is mounted on the rotary arm as a whole, and the first supporting bracket 203 provides fixed support for the first mounting frame 2021 as a whole. The first driving wheel 20223 and the four transmission wheels 20224 are all rotatably connected to the first mounting frame 2021, wherein two transmission wheels 20224 are arranged at both ends of the length direction of the first mounting frame 2021, and the transmission belt 20222 is wound around the first driving wheel 20223 and the four transmission wheels 20224, and the overall layout is in a reverse Ω shape, specifically as shown in FIG. Figure 8 The first driving wheel 20223 and the four transmission wheels 20224 are all arranged horizontally in their rotational axes. The first motor 20221 is fixedly mounted on the first mounting frame 2021, and the output shaft of the first motor 20221 is in transmission connection with the first driving wheel 20223. Therefore, when the first motor 20221 is started, the transmission belt 20222 is driven to rotate synchronously via the first driving wheel 20223 and the four transmission wheels 20224.

[0085] Reference Figure 7 As shown, in this embodiment, the displacement assembly 201 is a slide as a whole, which is slidably connected with the guide rail. A belt clamping portion 2012 is provided at the bottom of the slide. The belt clamping portion 2012 is paired with the transmission belt 20222. The belt clamping portion 2012 clamps the transmission belt 20222. Therefore, the operation of the transmission belt 20222 will synchronously drive the displacement assembly 201 as a whole to move on the guide rail, and finally achieve the effect of driving the conveying vehicle 10 to move on the first conveyor line 20 to convey the goods.

[0086] Reference Figure 8As shown, in one embodiment, the first connecting structure 101, the second connecting structure 2011, and the unlocking mechanism 40 are further refined. The second connecting structure 2011 includes a connecting member. The first connecting structure 101 includes a first mounting seat and a latching member 1011. The first mounting seat is fixedly mounted on the transport carrier 10, and the latching member 1011 is movably mounted on the first mounting seat.

[0087] It should be noted that, in this embodiment, the latch 1011 is slidably connected to the first mounting seat, and the sliding direction is perpendicular to the conveying direction of the first conveyor line 20. The latch 1011 includes a semi-annular block 10112, and the connecting member is arranged as a whole in a cylindrical shape, corresponding to the block 10112. The block 10112 can be slidably engaged with the connecting member to achieve a snap connection with the connecting member as a whole. At this time, the block 10112 limits the moving direction of the connecting member. Conversely, when the displacement assembly 201 is driven by the first driving mechanism 202, the connecting member will drive the first mounting seat and the conveying carrier 10 as a whole to move on the first conveyor line 20 through the latch 1011.

[0088] Specifically, the entire latch 1011 is slidably connected to the first mounting seat. The latch 1011 also includes a push rod 10111, one end of which is connected to the clamping block 10112, and the other end of which extends outward. The first connecting structure 101 also includes an elastic return member. In this embodiment, the elastic return member is specifically a spring 1012, one end of which is connected to the first mounting seat and the other end is connected to the latch 1011. The elastic return member drives the latch 1011 to move toward the connecting member, causing the latch 1011 to be pressed tightly against the connecting member.

[0089] Specifically, the spring 1012 is wound around the top rod 10111, one end of the spring 1012 is connected to the first mounting seat, and the other end is connected to the top rod 10111. The spring 1012 is arranged in a compressed state as a whole. When the first connecting structure 101 is not subjected to external force other than the elastic force of the spring 1012, the elastic force of the spring 1012 drives the top rod 10111 to move away from the first mounting seat, and the top rod 10111 drives the clamping block 10112 to move toward the connecting member until the clamping block 10112 is locked and pressed tightly on the connecting member. The setting of the spring 1012 can improve the connection stability between the first connecting structure 101 and the second connecting structure 2011. Therefore, when the displacement assembly 201 drives the conveying carrier 10 to move, the clamping member 1011 can be pressed tightly on the connecting member, thereby improving the operating stability of the conveying carrier 10 and avoiding the situation where the clamping block 10112 is accidentally separated from the connecting member.

[0090] In this embodiment, the unlocking mechanism includes a second mounting seat 401, an unlocking member 402 and an unlocking drive assembly 403. The second mounting seat 401 is fixedly mounted on the second conveyor line 30. The unlocking member 402 is movably arranged on the second mounting seat 401, and the unlocking drive assembly 403 is a telescopic drive device, which can be a telescopic cylinder or a telescopic oil cylinder. Specifically, in this embodiment, the unlocking drive assembly 403 is a telescopic cylinder, and the telescopic shaft of the telescopic cylinder is connected to the unlocking member 402 to drive the unlocking member 402 to move telescopically. When the conveying carrier 10 is in the connecting position, the push rod 10111 is in the moving stroke of the unlocking member 402, and the unlocking member 402 pushes the push rod 10111 to drive the block 10112 to disengage from the connecting member. When the conveying carrier 10 moves to the connecting position, the displacement assembly 201 combined with the conveying carrier 10 moves to the position corresponding to the unlocking mechanism, and at this time the push rod 10111 is in the moving stroke of the unlocking member 402.

[0091] For example, when the conveying carrier 10 on the first conveyor line 20 moves to the connecting position, the displacement assembly 201 is in a position corresponding to the unlocking mechanism. At this time, the unlocking drive assembly 403 can be controlled, and the telescopic shaft drives the unlocking member 402 to press the push rod 10111, causing the block 10112 to disengage from the connecting member. At this time, the displacement assembly 201 is disconnected from the conveying carrier 10 as a whole, thereby realizing the transmission unlocking of the first connecting structure 101 and the second connecting structure 2011.

[0092] More preferably, since the top rod 10111 is arranged in a cantilevered manner as a whole, in order to improve the overall rigidity of the top rod 10111, a fixing seat 102 is provided on the conveying carrier 10, and the end of the top rod 10111 is passed through the fixing seat 102, and the fixing seat 102 has the effect of auxiliary support for the top rod 10111.

[0093] In one embodiment, in order to improve the displacement accuracy of the unlocking member 402, two guide wheels 103 are rotatably connected to the fixed seat 102. The two guide wheels 103 are located on both sides of the push rod 10111 to guide the extension and retraction of the unlocking member 402. When the unlocking member 402 presses the push rod 10111, the two sides of the unlocking member 402 are respectively in contact with the two guide wheels 103.

[0094] Reference Figure 11 As shown, in one embodiment, the second conveyor line 30 is further refined, and the second conveyor line 30 also includes a second supporting bracket. The second driving mechanism 301 is arranged along the conveying direction of the second conveyor line 30 as a whole. There are at least two second supporting brackets, and the second supporting brackets are arranged on both sides of the second driving mechanism 301 and are spaced apart along the length direction of the second driving mechanism 301, and are used as a whole to support the second driving mechanism 301.

[0095] The second drive mechanism 301 includes a second mounting frame 3011, a roller assembly, and a drive unit 3013. The second mounting frame 3011 is disposed along the conveying direction of the second conveyor line 30, and two second mounting frames 3011 are symmetrically arranged. The roller assembly includes a plurality of transmission rollers 30131, which are rotatably connected to the second mounting frame 3011 and spaced apart along the conveying direction of the second mounting frame 3011. The transmission rollers 30131 are used to support the conveying carrier 10.

[0096] In this embodiment, the drive unit 3013 includes a second belt drive assembly and a second motor 30132. The second motor 30132 is fixedly mounted on one of the second mounting frames 3011. The transmission rollers 30131 on the two second mounting frames 3011 are connected to each other via a synchronous belt transmission, achieving tandem rolling. A second driving wheel 30133 is rotatably connected to each of the second mounting frames 3011. The second driving wheel 30133 is connected to one of the transmission rollers 30131 via a synchronous belt transmission. Therefore, rotation of the second driving wheel 30133 drives the transmission roller 30131 on the same second mounting frame 3011 via the synchronous belt transmission. A transmission shaft 30134 is disposed across the two second mounting frames 3011. The transmission shaft 30134 is transmission-connected to the two second driving wheels 30133, and one of the second driving wheels 30133 is transmission-connected to the output shaft of the second motor 30132.

[0097] Illustratively, the rotation of the motor will drive the second driving wheel 30133 to rotate through the output shaft, and then the second driving wheel 30133 will drive the transmission roller 30131 on the same second mounting frame 3011 to rotate synchronously through the synchronous belt. At the same time, the second driving wheel 30133 will drive the second driving wheel 30133 on another second mounting frame 3011 to rotate synchronously through the transmission shaft 30134. Finally, the start-up of the motor will synchronously drive the transmission rollers 30131 on the two second mounting frames 3011 to rotate. When the conveying carrier 10 enters the second conveyor line 30, the bottom of the conveying carrier 10 will contact the transmission roller 30131 located at the end. The rotation of the transmission roller 30131 will drive the conveying carrier 10 to move and transport on the second conveyor line 30, thereby achieving the driving effect.

[0098] Specific implementation process:

[0099] On the production line, when the conveyor carrier 10 is transported on the first conveyor line 20, the clamping block 10112 is engaged with the connector by the spring 1012, connecting the first connecting structure 101 and the second connecting structure 2011. Because the belt clamping portion 2012 clamps the transmission belt 20222, the movement of the transmission belt 20222 synchronously drives the entire displacement assembly 201 to move on the guide rail.

[0100] When the high-speed conveyor line hands over the conveyor carrier 10 to the low-speed conveyor line, the conveyor carrier 10 enters the connecting position. When the conveyor carrier 10 on the first conveyor line 20 moves to the connecting position, the displacement component 201 is in a position corresponding to the unlocking mechanism. At this time, the unlocking drive component 403 can be controlled, and the telescopic shaft drives the unlocking member 402 to press the push rod 10111, causing the block 10112 to disengage from the connecting member. At this time, the displacement component 201 is disconnected from the conveyor carrier 10 as a whole, thereby realizing the transmission unlocking of the first connecting structure 101 and the second connecting structure 2011.

[0101] When the conveying carrier 10 is in the connecting position, a part of the conveying carrier 10 enters the second conveyor line 30, so the transmission roller 30131 contacts the conveying carrier 10. When the displacement component 201 is disconnected from the conveying carrier 10 as a whole, the rotation of the transmission roller 30131 will drive the conveying carrier 10 to be displaced and transported on the second conveyor line 30. At this point, the handover of the conveying carrier 10 from the first conveyor line 20 to the second conveyor line 30 is completed.

[0102] Compared with the prior art, the coordinated arrangement of the first connecting structure 101, the second connecting structure 2011 and the unlocking mechanism 40 synchronously realizes the transfer and handover of the mobile carrier at the connecting position of the conveying system. By switching the transmission connection state of the conveying carrier 10, the conveying carrier 10 can be stably and quickly transferred from the high-speed first conveying line 20 to the low-speed second conveying line 30, which solves the problem of low handover efficiency at the handover point of the conveying equipment in the prior art, has the advantage of higher handover efficiency, and has higher overall practicality.

[0103] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 as well as Figure 11 As shown, in one embodiment, the composite conveying system as a whole includes three groups of conveying lines, among which the second conveying line 30 is provided with two groups, namely the second conveying line 30, the first conveying line 20 and the second conveying line 30 in sequence. Similarly, in this embodiment, according to the actual needs of the work station, the first conveying line 20 is set as a high-speed conveying line and the second conveying line 30 is a low-speed conveying line.

[0104] In this embodiment, since there are three groups of conveyor lines, unlocking mechanisms 40 are provided at the two connection points of the conveyor lines. Specifically, in this embodiment, the unlocking mechanisms 40 are provided on the second conveyor line 30, specifically at the end of the second conveyor line 30 close to the connection position.

[0105] It should be noted that, in this embodiment, the workstations of the two second conveyor lines 30 are spaced far apart, and the overall conveying distance of the first conveyor line 20 is longer. In order to maintain the overall driving efficiency of the first conveyor line 20, in this embodiment, two first transmission components 2022 are provided, and two displacement components 201 are correspondingly provided. The two first transmission components 2022 are combined in a segmented and intersecting manner to form a first conveyor line 20 with a longer conveying distance. The two first transmission components 2022 form an intersection point at the intersection. In order to realize the intersection of the conveying carrier 10 on the two displacement components 201, an unlocking mechanism 40 is also provided at the intersection. In addition, in order to enable the two first transmission components 2022 to drive their corresponding displacement components 201 to the intersection point, the drive belts 20222 on the two first transmission components 2022 are staggered. At the same time, the belt clamping parts 2012 on the two displacement components 201 are also staggered with each other. The two displacement components 201 share two tracks. Such a staggered arrangement can avoid motion interference. When the displacement assembly 201 moves to the intersection point, the push rod 10111 is located on the moving stroke of the unlocking member 402.

[0106] For example, when the conveying carrier 10 is conveyed on the first conveyor line 20, the buckle block on the conveying carrier 10 is engaged with the connecting piece on one of the displacement components 201, and one set of first transmission components 2022 drives the conveying carrier 10 to move to the intersection through the displacement component 201. At this time, the unlocking mechanism 40 is controlled to unlock the displacement component 201, and the unlocking component 402 pushes the push rod 10111 to drive the block 10112 to disengage from the connecting piece. After unlocking, the displacement component 201 returns under the drive of the first transmission component 2022; the other first transmission component 2022 drives the other displacement component 201 to move forward. When it reaches the intersection, the push rod 10111 is still pressed by the extended telescopic shaft, so the connecting piece on the other displacement component 201 will not be interfered with by the blocking block 10112, and the displacement component 201 can enter the intersection. After the displacement component 201 is in place, the unlocking mechanism 40 can be controlled to drive the telescopic shaft to retract, and the push rod 10111 drives the blocking block 10112 to move and engage with the connecting piece under the action of the elastic force of the spring 1012. At this time, the displacement component 201 and the conveying carrier 10 realize transmission connection, and the connection between the conveying carriers 10 on the two first transmission components 2022 in the first conveyor line 20 is completed.

[0107] It should be noted that the overall conveying length of the first conveyor line 20 can be set according to the actual production line requirements. When the length is longer, the first transmission component 2022 and the displacement component 201 can be staggered with each other, which will not be elaborated here.

[0108] More preferably, in this embodiment, the first conveyor line 20 is connected to the second conveyor line 30 to form a main conveyor line, and end limit modules 50 are provided at both ends of the main conveyor line. The end limit module 50 is located at the end of the main conveyor line and is located on the moving range of the conveying carrier 10 to limit the conveying carrier 10 from leaving the main conveyor line.

[0109] For example, in this embodiment, the driving method for the conveying carrier 10 on the second conveyor line 30 is the rotational drive of the transmission roller 30131. When the conveying carrier 10 is conveyed to the end of the second conveyor line 30 by the transmission roller 30131, the conveying carrier 10 contacts the end limit module 50. The end limit module 50 restricts the conveying carrier 10 from leaving the second conveyor line 30, thereby achieving the effect of end limit.

[0110] In one embodiment, depending on the operational requirements of the production line, the composite conveyor system may further include two lifting mechanisms 60, with the two second conveyor lines 30 being disposed on lifting members 61 of the two lifting mechanisms 60, respectively. When the lifting members 61 are at their lowest position, one end of the second conveyor line 30 is connected to the first conveyor line 20. When the transport carrier 10 fully enters the second conveyor line 30, the lifting mechanisms 60 can be manipulated to raise or lower the entire second conveyor line 30.

[0112] The workstation as a whole is equipped with a high-speed conveyor line and a low-speed conveyor line. The whole realizes efficient alternating connection through the cooperation of the first connection structure and the unlocking device. Compared with the existing technology, the overall work efficiency is extremely high.
