Description

Technical Field

[0001] This utility model relates to the technical field of production line conveying systems, and specifically to a seamless transition conveying system. Background Technology

[0002] On the production line of large-scale engineering cabinet machines, in order to achieve flexible production, core processes such as assembly, testing, and packaging usually need to be physically separated into segments. During the transfer from the assembly segment to the testing segment, or from the testing segment to the packaging segment, most companies still use overhead cranes or forklifts to move large cabinet machines. This traditional transportation method is not only inefficient, resulting in a slow production line cycle, but also involves a large amount of repetitive physical labor, increasing the workload of workers. Furthermore, it requires long training times for skilled assembly workers and has a high turnover rate.

[0003] Therefore, some companies have begun to introduce automated conveyor equipment for transporting cabinet units between different process stages. However, for large and heavy cabinet units, such as high-voltage frequency converter cabinet units, their weight is often several tons, or even as high as 7 to 8 tons. To protect the machine body and facilitate handling, such heavy equipment is usually placed on special wooden pallets for circulation. The bottom of the wooden pallet is designed with a crisscrossing support beam structure, which is about 60mm thick. Due to the significant differences in size, weight, and center of gravity distribution among different models of cabinet units, when the wooden pallet carrying the cabinet unit crosses the interface between different process stages, such as through chain conveyors or roller conveyor sections, the wooden pallet structure will bend and deform due to the huge concentrated load. The maximum deformation of its bottom transverse support beams can reach 45mm. This deformation can easily cause the wooden pallet to "jam" when entering subsequent conveyor equipment due to insufficient clearance under the beams or misalignment. Jaw jamming not only causes conveyor interruption and seriously affects the overall production efficiency, but may also pose safety risks to the equipment structure and the cabinet unit itself.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0019] If the description of this utility model involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.), then the directions involved need to be defined. For example, "To clearly express the position and direction described in this utility model, the operator of the instrument is used as a reference, the end closer to the operator is the proximal end, and the end farther from the operator is the distal end." Or, the paper can be used as a reference. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, then this definition is not required.

[0020] A seamless transition conveying system, such as Figures 1-4As shown, the device includes a support 1 and a motor 2 mounted on the support 1. A first chain conveyor 3, a transition device 4, and a second chain conveyor 5, all having the same conveying direction, are sequentially mounted on the support 1. The conveying direction is from the first chain conveyor 3 to the second chain conveyor 5 or from the second chain conveyor 5 to the first chain conveyor 3. The transition device 4 includes a transition support 401 and several parallel rotating rollers 402 mounted on the transition support 401. The motor 2 can drive the rotating rollers 402 to rotate. Connecting plates 6 are respectively provided between the first chain conveyor 3 and the rotating rollers 402, and between the rotating rollers 402 and the second chain conveyor 5, for connecting the conveying planes. When conveying wooden pallets or other products along the conveying direction, the wooden pallets can be pushed by the first chain conveyor 3 / second chain conveyor 5 through the connecting plates 6 onto the rotating rollers 402, and then conveyed by the several rotating rollers 402 into the second chain conveyor 5 / first chain conveyor 3. As one embodiment of this utility model, such as Figure 5 , 6As shown, the upper surface of the connecting plate 6 (i.e., the surface near the conveying plane) includes a connecting surface 601 and a guide surface 602 inclined relative to the connecting surface 601. The guide surface 602 and the connecting surface 601 have a small inclination angle. The wooden pallet gradually enters the connecting surface 601 through the inclined guide surface 602. The connecting surface 601 is located near the rotating roller 402, and the guide surface 602 is located away from the rotating roller 402. The connecting surface 601 is flush with the conveying plane of the rotating roller 402. The connecting surface 601 is also flush with the conveying planes of the first chain plate conveying device 3 and the second chain plate conveying device 5. The guide surface 602 extends from the plane where the connecting surface 601 is located towards the bottom of the connecting plate 6. The guide surface 602 is lower than the conveying planes of the adjacent first chain plate conveying device 3 and second chain plate conveying device 5, that is, there is a height difference D between the guide surface 602 and the conveying planes of the first chain plate conveying device 3 and second chain plate conveying device 5. When the chain plate 302 is conveyed from the first chain plate conveyor 3 / second chain plate conveyor 5 towards the rotating roller 402, the chain plate 302 near the rotating roller 402 will rotate with the chain 301. The conveying plane of this chain plate 302 will tilt downward relative to the conveying plane of the entire chain plate 302 conveyor. At this time, the bottom surface of the wooden pallet on this chain plate 302 near the rotating roller 402 will also be lower than the original conveying plane of the first chain plate conveyor 3 / second chain plate conveyor 5. Therefore, under the conveying of the first chain plate conveyor 3 / second chain plate conveyor 5, the wooden pallet can enter the connecting plate 6 through the guide surface 602 which is slightly lower than the entire conveying plane before the bottom surface position is further lowered, preventing the wooden pallet from getting stuck between the connecting plate 6 and the tilted chain plate 302. Correspondingly, when the wooden pallet is conveyed from the rotating roller 402 to the second chain conveyor 5 / first chain conveyor 3, since the chain plate 302 near the rotating roller 402 is lower than the conveying plane, the guide surface 602 can reduce the height difference of the wooden pallet entering the chain plate 302, avoiding collisions. The wooden pallet can also gain an upward and in the conveying direction pushing force through the rotation of the chain plate 302 to enter the next level of the conveying plane. The specific value of the height difference D needs to be calculated and determined based on parameters such as the actual weight of the wooden pallet and the loaded items, and the width of the chain plate 302.

[0021] In order to reduce the cost and space required for the entire transition system, this invention uses the same motor 2 to drive the first chain plate conveyor 3 and the transition components.

[0022] As one embodiment of this utility model, such as Figure 3 , 4As shown, the first chain plate conveying device 3 includes several chains 301 arranged in parallel and several chain plates 302 arranged in parallel on the chains 301. The arrangement direction of the chain plates 302 is perpendicular to the arrangement direction of the chains 301 and parallel to the conveying direction. One chain plate 302 can span multiple chains 301. A drive shaft 303 and a driven shaft are rotatably arranged on the support 1. At least two sets of bearing seats 304 and first bearings arranged on the bearing seats 304 are provided on the support 1. The two ends of the drive shaft 303 are respectively arranged in the two first bearings to satisfy the rotational freedom. A plurality of drive sprockets 305, which rotate synchronously with the drive shaft 303, are sleeved on the drive shaft 303. A plurality of driven sprockets, which rotate synchronously with the driven shaft, are sleeved on the driven shaft. The drive sprockets 305, driven sprockets, and chain 301 are corresponding to and mesh with each other. A first transmission assembly is provided between the motor 2 and the drive shaft 303. The motor 2 can drive the first transmission assembly to transmit driving force to the drive shaft 303, thereby driving the drive sprockets 305 to rotate. The rotation of the drive sprockets 305 drives the chain 301 to rotate. The chain plate 302 located on the chain 301 is movable to transport products.

[0023] Specifically, such as Figure 7 As shown, the chain plate 302 includes a panel 3021 for forming and providing a conveying plane and baffles 3022 extending from both ends of the panel 3021 in the conveying direction to the same side. The panel 3021 and baffles 3022 have a rounded transition to enhance the connection strength between them. Simultaneously, if rotation occurs, the contact surface between the chain plate 302 and the wooden pallet is curved, preventing damage to the wooden pallet. Adjacent baffles 3022 of two adjacent chain plates 302 can be used to minimize the gap between them. When the chain plate 302 rotates to the rounded section near the chain 301, an approximately V-shaped blocking portion is formed between the two baffles 3022 of two adjacent chain plates 302 to prevent the wooden pallet or other products from getting stuck between the two chain plates 302. A reinforcing member 3023 is provided between the two side baffles 3022. The reinforcing member 3023 is used to enhance the structural strength of the chain plate 302 to accommodate large-mass conveyed items. Specifically, the reinforcing member 3023 can be a rectangular tube with an internal central hole.

[0024] As one embodiment of this utility model, such as Figure 4As shown, the first transmission assembly includes a first double-row sprocket 306 and a second double-row sprocket 307. The first double-row sprocket 306 is mounted on the output shaft of the motor 2, and the second double-row sprocket 307 is mounted on the drive shaft 303 and rotates synchronously with the drive shaft 303. A double-row chain 308 is provided between the first double-row sprocket 306 and the second double-row sprocket 307 for connection and power transmission, thereby driving the drive shaft 303 to rotate. Using a double-row sprocket-double-row chain transmission method within a limited space increases the meshing points in the width direction, improves transmission power and capacity, and enhances transmission smoothness, ensuring the stability of the conveying process.

[0025] In one embodiment of this utility model, a power sprocket 403 that rotates synchronously with the rotating roller 402 is provided at one end of the rotating roller 402. The motor 2 can drive the power sprocket 403 to rotate. A second bearing is provided on the transition bracket 401. The other end of the rotating roller 402 is provided in the second bearing. Through the second bearing, the rotating roller 402 is rotatably mounted on the transition bracket 401. Two adjacent rotating rollers 402 are staggered in the axial direction, and the power sprocket 403 of one of the rotating rollers 402 is located at the end of the rotating roller 402 that is furthest from the power sprocket 403 of the adjacent rotating roller 402. That is, the power sprockets 403 of two adjacent rotating rollers 402 are respectively located at the two positions that are furthest apart in the axial direction, thereby reducing the distance between the two adjacent rotating rollers 402. If several rotating rollers 402 are arranged side by side, and the drive sprockets 403 are all located on the same side of the rotating rollers 402, then there will be at least the distance of one drive sprocket 403 between two adjacent rotating rollers 402. However, the diameter of the rotating rollers 402 is usually smaller than the diameter of the drive sprockets 403. This will increase the distance between two adjacent rotating rollers 402, potentially resulting in a large gap between them. The conveyed wooden pallets or other transverse support beams may easily get stuck in this gap, affecting transmission. Therefore, the staggered arrangement of the rotating rollers 402 and the intermittently driven drive sprockets 403 can reduce the gap between adjacent rotating rollers 402, avoiding the aforementioned problems, and also making the transition system more compact and saving space.

[0026] As an embodiment of the present invention, a second transmission component is provided at each end of the drive shaft 303. The second transmission component is used to transmit the rotation of the drive shaft 303 to the power sprocket 403 of the rotating roller 402 located on the same side as it.

[0027] In one embodiment of this utility model, the second transmission assembly includes a transmission shaft 404 rotatably mounted on a support 1. Specifically, a transmission support 401 is provided on the support 1, and the transmission shaft 404 is rotatably mounted on the transmission support 401. A second sprocket transmission mechanism is provided between one end of the transmission shaft 404 and the drive shaft 303, and a fifth transmission sprocket 406 that rotates synchronously with the transmission shaft 404 is provided at the other end of the transmission shaft 404. The transmission shaft 404 transmits power to the fifth transmission sprocket 406 through the second sprocket transmission mechanism. A third transmission chain 407 is provided between the fifth transmission sprocket 406 and at least one drive sprocket 403 located on the same side for connection and transmission. A synchronization chain 408 is provided between two adjacent drive sprockets 403 located on the same side for connection to transmit rotation.

[0028] Specifically, the second sprocket transmission mechanism includes a third transmission sprocket 4051, a fourth transmission sprocket 4052, and a second transmission chain 4053. The third transmission sprocket 4051 is mounted on the drive shaft 303 and rotates synchronously with the drive shaft 303. The fourth transmission sprocket 4052 is mounted at the end of the transmission shaft 404 away from the fifth transmission sprocket 406 and drives the transmission shaft 404 to rotate synchronously. The second transmission chain 4053 connects the third transmission sprocket 4051 and the fourth transmission sprocket 4052 and transmits rotation.

[0029] As one embodiment of this utility model, such as Figure 8 As shown, a first tensioning mechanism is provided on the bracket 1, which is used to adjust the tension of the chain 301. Specifically, the first tensioning mechanism includes a slider 701, a lead screw 702, and a stop nut 703. A slide rail 101 parallel to the conveying direction is provided on the bracket 1. The slider 701 is fixed to the end of the drive shaft 303, and a groove is provided on the slider 701 to cooperate with the slide rail 101, allowing the slider 701 to slide on the slide rail 101. One end of the lead screw 702 is fixed to the slider 701, and the other end of the lead screw 702 is provided on the bracket 1. The stop nut 703 is fixed to the lead screw 702. The rod 702 is threaded and used to lock the lead screw 702. When the locking nut 703 is rotated to unlock the lead screw 702, the position of the lead screw 702 and the slider 701 located on the lead screw 702 can be adjusted by rotating the lead screw 702. Thus, the slider 701 can slide along the slide rail 101 and thereby adjust the position of the drive shaft 303 and the drive sprocket 305. The tension of the chain 301 can also be adjusted. After the adjustment is completed, the locking nut 703 is rotated again to lock and fix the position of the lead screw 702.

[0030] In one embodiment of this utility model, a second tensioning mechanism 8 is provided on the bracket 1. The second tensioning mechanism 8 is used to adjust the tension of the third transmission chain 407. Specifically, the second tensioning mechanism 8 can adopt an adjustable tensioning sprocket structure. The tensioning sprocket abuts against the third transmission chain 407 and partially engages with the third transmission chain 407. The tension of the third transmission chain 407 is adjusted by adjusting the position of the tensioning sprocket.

[0031] The seamless transition conveying system provided by this utility model achieves seamless connection when conveying wooden pallets into or out of the transition device 4 during the conveying process by setting a connecting plate 6 with a guide surface 602, thus avoiding the risk of wooden pallets getting stuck; the use of staggered driven rotating rollers 402 reduces the gap between rotating rollers 402 and maintains the integrity of the conveying plane; through the conveying between automated process sections, production efficiency is improved and the floor space of the assembly line is saved.

[0032] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
