Description

Technical Field

[0001] This application relates to the field of lifting and transferring devices, and in particular to a lifting and transferring device with high safety. Background Technology

[0002] Lifting and transferring devices are generally used in automated production lines. They can automatically control 90° reversing conveyor equipment to change the conveying direction of goods, moving them from the forklift to the main conveyor line. They need to provide multiple functions such as lifting, transitioning, turning, tilting, positioning, and shifting. They are specialized equipment that plays a supporting role in the conveying process and are generally configured in a complete conveyor system.

[0003] In actual use, due to space limitations, the lifting and transfer device and the conveying equipment need to be arranged in a cross pattern in order to save space occupied by the automated production line equipment.

[0004] As attached Figure 8 As shown, existing lifting and transferring devices typically include a transmission mechanism 3, a lifting mechanism 4, and a transferring mechanism 6. Material is conveyed from the transmission mechanism 3 to the surface of the transferring mechanism 6. The lifting mechanism 5 lifts the transferring mechanism 6, and the transferring mechanism 6 then reverses the material transport. However, when the transferring mechanism 6 reverses the material transport, a frame 2 is provided between the transferring mechanism 6 and the next connecting transmission mechanism 3. This creates a gap between the transferring mechanism 6 and the next transmission mechanism 3, causing instability when the transferring mechanism 6 transports the material to the next transmission mechanism 3, and the material may fall. Therefore, it is often necessary to align both ends of the transferring mechanism 6 with the frame 2 to ensure the stability of the transferring mechanism 6 in transporting the material to the next transmission mechanism 3.

[0005] However, when the end of the transfer mechanism 6 is flush with the frame 2, the lifting mechanism 5 will lift the transfer mechanism 6 up and down, causing the transfer mechanism 6 to collide with the transmission mechanism 3. This will cause the transmission mechanism 3 to stop conveying materials and the production line to be suspended. Therefore, when the lifting mechanism 5 lifts the transfer mechanism 6, it is necessary to separate the transfer mechanism 6 from the transmission mechanism 3 to ensure the safety of the transfer mechanism 6 moving up and down and the transmission mechanism 3 transmitting materials. Utility Model Content

[0006] To improve the safety performance between the vertical movement of the transfer mechanism and the transmission of the transfer mechanism, a lifting and transfer device with high safety is provided.

[0007] The above-mentioned objective of this application is achieved through the following technical solution:

[0008] A highly safe lifting and transferring device includes two sets of relatively parallel frames. A transmission mechanism for transferring the iron core body is mounted on each frame. A lifting mechanism is located between the two sets of frames, and a transferring mechanism is located above the lifting mechanism. The transmission direction of the transmission mechanism is perpendicular to that of the transferring mechanism. The transmission mechanism includes a transmission chain and multiple rotating rollers. A clearance end is provided between adjacent rotating rollers. A fixed plate is provided between the two sets of frames. Multiple pull-down sprockets are rotatably connected to the upper end of the fixed plate. Each pull-down sprocket corresponds to a clearance end and is located below it. The transferring mechanism includes multiple transferring components, each corresponding to a clearance end and located within it. Both ends of each transferring component are flush with the two sets of frames. A rotating meshing sprocket is mounted on one end of each rotating roller. The transmission chain passes sequentially through the top surfaces of the multiple rotating meshing sprockets and the bottom surfaces of the multiple pull-down sprockets, engaging with them for transmission.

[0009] By adopting the above technical solution, a clearance end is provided between two adjacent rotating rollers, and the transfer component can be lifted within the clearance end. At the same time, multiple pull-down sprockets are provided below the transfer component, and the pull-down sprockets are located below the clearance end. As a result, when the transmission chain passes through the pull-down sprockets, it will change the transmission direction of the transmission chain, separating the transfer component from the transmission chain, avoiding collision between the transfer component and the transmission chain during lifting, ensuring the safety of the transfer mechanism's transmission reversal, and improving the safety performance of the transfer component.

[0010] Optionally, the transmission mechanism further includes a drive chain and a first motor. A driven sprocket is also provided on one end of the rotating roller near the rotating meshing sprocket. A drive sprocket is connected to the output shaft of the first motor. The drive chain passes through the drive sprocket and the driven sprocket respectively and meshes with them for transmission.

[0011] By adopting the above technical solution, if only a transmission chain is used to mesh and drive the first motor and the rotating roller, the tension of the transmission chain will make the transmission chain susceptible to breakage due to environmental factors, thus increasing the number of maintenance times. By adding a drive chain, the tension between the drive chain and the first motor is greater than the tension between the transmission chain and the rotating roller. Therefore, if the drive chain breaks, maintenance and replacement are more convenient, and it is also easier to adjust the transmission ratio between the drive chain and the first motor.

[0012] Optionally, the transfer assembly in the same group includes a chain plate and a chain belt. Both ends of the chain plate are provided with synchronous pulleys, and the chain belt is sleeved on the two synchronous pulleys corresponding to the same chain plate.

[0013] By adopting the above technical solution, the chain plate can protect and support the chain, ensuring that the chain remains taut during operation. This prevents the chain from loosening or falling off during movement, avoiding instability or malfunctions caused by chain slack, thereby improving the stability and reliability of the entire equipment.

[0014] Optionally, the transfer assembly in the same group includes a support base, one end of which is connected to the chain plate and the other end is fixedly connected to the support panel.

[0015] By adopting the above technical solution, when the iron core body passes over the surface of the chain belt, the structure of the chain plate and the support seat can disperse the pressure exerted by the iron core body on the chain belt, avoid the hidden danger of deformation of the iron core body on the chain belt, and improve the safety performance of the chain belt transmission.

[0016] Optionally, the number of support seats of the transfer components in the same group is multiple, and they are evenly distributed on the support panel.

[0017] By adopting the above technical solution, the load-bearing capacity of the transfer component on the iron core body is increased, which can be used to transport some heavier iron core bodies. This avoids the iron core body being too heavy and pressing down on the transfer component, thus preventing it from getting stuck between the rotating rollers and improving the safety performance of the iron core body transport.

[0018] Optionally, a support panel is provided between the lifting mechanism and the transfer mechanism, with the lifting mechanism located below the support panel and the transfer assembly located above the support panel.

[0019] By adopting the above technical solution, the support panel can provide a stable plane, ensuring that the iron core body can be smoothly moved from the transmission mechanism to the transfer mechanism during the lifting and transfer process. This distributes the weight of the iron core body evenly on the support panel, reduces local stress concentration, and prevents the object from tilting or slipping during the movement, thus improving the safety performance of the conveying process.

[0020] Optionally, a support column is fixed on the side of the support panel facing away from the transfer mechanism. A guide shaft is movably installed inside the support column. The upper end of the support column is tightly connected to the support panel, and an elastically deformable buffer ring is sleeved on the outer peripheral side wall of the lower end of the support column. Both ends of the buffer ring are fixedly connected to the support column.

[0021] By adopting the above technical solution, the support column can provide additional support points for the support panel, dispersing the pressure on the support panel caused by the weight of the iron core body. At the same time, the contact between the support column and the support panel may generate a large impact force, and the buffer ring can absorb this stress, reducing the vibration and shaking caused by the lifting mechanism driving the transfer components on the support panel to descend, thus ensuring the stable operation of the equipment.

[0022] Optionally, there may be multiple support columns, which are fixed at both ends of the support panel on the side facing away from the transfer mechanism.

[0023] By adopting the above technical solution, multiple support plates can provide greater support force to the support panel. At the same time, support columns are provided on both sides of the support panel to ensure that the support panel is evenly stressed and improve the stability of the support panel when the lifting mechanism moves the support panel up and down.

[0024] In summary, this application has at least the following beneficial effects:

[0025] 1. A clearance end is provided between two adjacent rotating rollers. The transfer component is lifted within the clearance end. The pull-down sprocket is located below the clearance end. As the transmission chain passes through the pull-down sprocket, it changes the transmission direction of the transmission chain, separating the transfer component from the transmission chain. This prevents the transfer component from colliding with the transmission chain during lifting and ensures the safety of the transfer mechanism's transmission reversal.

[0026] 2. The support column can disperse the pressure on the support panel caused by the weight of the iron core body, while the buffer ring can reduce the vibration and shaking caused by the lifting mechanism driving the transfer components on the support panel to descend, ensuring stable operation of the equipment.

[0027] 3. Multiple support seats are evenly spaced and fixed above the support panel, and all support seats are connected to the chain plate, which increases the load-bearing capacity of the transfer assembly on the iron core body, and prevents the weight of the iron core body from being too heavy and pressing down on the transfer assembly and getting stuck between the two rotating rollers, thus improving the safety performance of the iron core body conveying.

[0037] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0038] As attached Figure 1 As shown, a high-safety lifting and transfer device includes a base plate 1, a frame 2, a transmission mechanism 3, and an iron core body 4.

[0039] One end of the frame 2 is fixedly connected to the base plate 1, and the other end extends upward. The frame 2 is set in two groups. The two groups of frames 2 are located on both sides of the base plate 1 and are relatively parallel. The first group of frames 2 contains multiple frames 2 that are relatively parallel. The second group of frames 2 contains multiple frames 2, and the middle frame 2 of the same group is located on the side of the side frame 2 facing the first group of frames 2.

[0040] The transmission mechanism 3 includes a rotating roller 31. The two ends of the rotating roller 31 are located at the upper ends of the two sets of frames 2 and are rotatably connected to the two sets of frames 2. There are multiple rotating rollers 31, which are equally spaced and arranged in parallel. A clearance end 313 is provided between adjacent rotating rollers 31. The top surface of the rotating roller 31 is higher than the top of the frame 2. The iron core body 4 for transmission is provided on the top surface of the rotating roller 31.

[0041] As attached Figure 2 and attached Figure 3 As shown, a lifting mechanism 5 is provided between the two sets of frames 2. The lifting mechanism 5 is located above the base plate 1. The lifting mechanism 5 includes a lifting component 51 and a support column 53.

[0042] One end of the lifting component 51 is fixedly connected to the base plate 1, and the other end is fixedly connected to the support panel 52. The support panel 52 is parallel to the base plate 1, and the lifting component 51 drives the support panel 52 to lift up and down.

[0043] There are multiple support columns 53. A guide shaft 532 is movably installed inside the support column 53. The lower end of the guide shaft 532 is fixedly connected to the base plate 1. The upper end of the support column 53 is fixedly connected to the support panel 52. An elastically deformable buffer ring 531 is sleeved on the outer peripheral wall of the lower end of the support column 53. Both ends of the buffer ring 531 are fixedly connected to the support column 53. The support column 53 can provide additional support points for the support panel 52. At the same time, the buffer ring 531 can buffer the impact force generated between the support column 53 and the support panel 52, ensuring that the lifting component 51 can stably lift the support panel 52.

[0044] As attached Figure 4 and attached Figure 5 As shown, a transfer mechanism 6 is provided on the side of the support panel 52 facing away from the base plate 1. The transfer mechanism 6 moves up and down relative to the frame 2 and is driven by the lifting mechanism 5. The transfer mechanism 6 includes a transfer component 61 and a transmission shaft 63.

[0045] The transfer assembly 61 consists of three sets, which are staggered with multiple rotating rollers 31. The transfer assembly 61 in the same set is equally spaced and parallel to the two rotating rollers 31. The three sets of transfer assemblies 61 are located in three clearance ends 313, and the two ends of the three sets of transfer assemblies 61 are flush with the two sets of frames 2.

[0046] The same group of transfer components 61 includes a chain belt 611, a chain plate 612 and a support base 613. The chain plate 612 is located inside the chain belt 611 and abuts against the chain belt 611. Both ends of the chain plate 612 are provided with synchronous pulleys 6121. The chain belt 611 is sleeved on the two synchronous pulleys 6121 corresponding to the same chain plate 612.

[0047] The drive shaft 63 is located above the base plate 1 and on the side close to the second set of frames 2. The synchronous wheel 6121 at one end of the chain plate 612 is located on the side of the middle frame 2 of the second set of frames 2 facing away from the first set of frames 2 and is sleeved on the drive shaft 63. The synchronous wheel 6121 at the other end of the chain plate 612 is located between the upper ends of the two frames 2 in the first set of frames 2.

[0048] Multiple support seats 613 are evenly spaced on both sides of the chain plate 612 in the same group. One end of the support seat 613 is connected to the chain plate 612, and the other end is fixedly connected to the support panel 52. When the iron core body 4 passes over the surface of the chain belt 611, the structure of the support seat 613 can disperse the pressure exerted by the iron core body 4 on the chain belt 611, and avoid the potential for deformation of the iron core body 4 on the chain belt 611.

[0049] The transfer mechanism 6 also includes a second motor 62 and a linkage chain 64. The second motor 62 is located on the side of the support panel 52 facing the base plate 1. The output shaft of the second motor 62 is connected to the first sprocket 621. The second sprocket 631 is passed through the transmission shaft 63. The linkage chain 64 passes through the first sprocket 621 and the second sprocket 631 respectively and meshes with them for transmission.

[0050] As attached Figure 6 and attached Figure 7 As shown, the transmission mechanism includes a first motor 32, a transmission chain 33, and a drive chain 34.

[0051] The first motor 32 is fixedly connected to the base plate 1. The first motor 32 is located on the side of the first frame 2 facing the second frame 2, and the first motor 32 is located at the edge of the base plate 1. A drive sprocket 321 is connected to the output shaft of the first motor 32.

[0052] The transmission mechanism 3 also includes two relatively parallel fixing plates 35. The fixing plates 35 are located on the side of the first set of frames 2 facing the second set of frames 2. One end of the two fixing plates 35 is fixedly connected to the base plate 1, and the other end extends upward and is located below the rotating roller 31.

[0053] A zipper wheel 351 is rotatably connected to one end of the fixed plate 35 facing away from the base plate 1. There are three zipper wheels 351, which are located below the three sets of transfer components 61 and below the three clearance ends 313.

[0054] The rotating roller 31 is provided with a transmission meshing sprocket 311 and a driven sprocket 312 on one end near the fixed plate 35.

[0055] The drive chain 34 passes through the drive sprocket 321 and the driven sprocket 312 respectively, and engages with them for transmission; the transmission chain 33 passes through the top surfaces of multiple rotating meshing sprockets 311 and the bottom surfaces of multiple pull-down sprockets 351 in sequence, and engages with them for transmission.

[0056] The transmission mechanism 3 transmits the iron core body 4 in the X direction, and the transfer component 61 transmits the iron core body 4 in the Y direction. The X direction of the transmission mechanism 3 is perpendicular to the Y direction of the transfer component 61.

[0057] Above the second set of frames 2, multiple sprocket covers 21 are also installed. The multiple sprocket covers 21 are located above the drive sprocket 311 and driven sprocket 312 of the rotating roller 31, respectively, to protect the drive sprocket 311 and driven sprocket 312 and prevent some impurities from falling into them and affecting the transmission of the transmission chain 33 and the drive chain 34.

[0058] The principle of this embodiment:

[0059] After the core body 4 is placed on the top surface of the rotating roller 31, the first motor 32 is started. The output shaft of the first motor 32 drives the drive chain 34 to rotate the rotating roller 31. After the rotating roller 31 rotates, it drives other rotating rollers 31 to rotate through the transmission chain 33. In this way, multiple rotating rollers 31 rotate simultaneously to transmit the core body 4 in the X direction.

[0060] When the rotating roller 31 needs to change direction to transfer the iron core body 4 to the transfer assembly 61, the lifting assembly 51 drives the support panel 52 to move upward, and then the support panel 52 drives the transfer mechanism 6 to move upward. The second motor 62 of the transfer mechanism 6 drives the linkage chain 64 to drive the transmission shaft 63 to rotate. When the transmission shaft 63 rotates, the transmission shaft 63 drives the synchronous wheel 6121 sleeved on the transmission shaft 63 to rotate, and then the synchronous wheel 6121 drives the chain belt 611 to drive, and the chain belt 611 transmits the iron core body 4 in the Y direction.

[0061] Meanwhile, a clearance end 313 is provided between two adjacent rotating rollers 31, and the transfer component 61 can be lifted within the clearance end 313. The pull-down sprockets 35 are located below the transfer component 61. The pull-down sprockets 35 change the transmission direction of the transmission chain 33. When the lifting component 51 drives the support panel 52 to lift the transfer component 61, it avoids collision between the lifting of the transfer component 61 and the transmission of the transmission chain 33, thus improving the safety performance of the cooperation between the transfer mechanism 6 and the transmission mechanism 3.

[0062] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
