Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying technology, and in particular to an article conveying device. Background Technology
[0002] In logistics sorting, food transportation, and warehousing facilities, conveyor systems are typically installed to transport goods to designated locations. These conveyor systems consist of multiple belt conveyors or roller conveyors arranged sequentially along the conveying direction. Both belt conveyors and roller conveyors have circular rollers at their ends. Gaps exist at the connection points between adjacent conveyors due to the circular rollers and the need for them to rotate and make room. When conveying thin, small, or soft-packaged goods, these items are easily caught in these gaps, leading to damage. To address this issue, existing technologies typically use support plates or driven rollers between adjacent conveyors to fill the gaps. However, because goods supported by these plates or rollers lack conveying power and rely solely on inertia to move, the conveying speed decreases or even stops when passing between adjacent conveyors, causing localized accumulation of goods and affecting the normal operation of the conveyor system.

[0032] Example 1
[0033] like Figures 1 to 7 As shown, this embodiment provides an article conveying device, which includes a first belt conveyor 1, a second belt conveyor 2, and a transition mechanism 3. The first belt conveyor 1 and the second belt conveyor 2 are arranged sequentially along the article conveying direction. The first belt conveyor 1 includes a first support roller 11 and a first conveyor belt 12. The second belt conveyor 2 includes a second support roller 21 and a second conveyor belt 22. The first support roller 11 and the second support roller 21 are adjacent to each other and spaced apart. The first conveyor belt 12 is sleeved on the first support roller 11 and supported by the first support roller 11. The second conveyor belt 22 is sleeved on the first support roller 11 and supported by the first support roller 11. Two support rollers 21 are provided, and the first conveyor belt 12 and the second conveyor belt 22 are spaced apart along the cargo conveying direction, forming a connecting seam 4 between them. The transition mechanism 3 includes a transition roller 31 and a transmission assembly 32. The transition roller 31 is rotatably installed in the connecting seam 4. The transmission assembly 32 includes a transmission roller 321, which abuts against the transition roller 31. The transmission roller 321 is also connected to the first belt conveyor 1 or the second belt conveyor 2. The transmission roller 321 is used to transmit the power of the first belt conveyor 1 or the second belt conveyor 2 connected to it to the transition roller 31. The article conveying device provided in this embodiment, by setting the transition roller 31 at the connecting seam 4 between the first conveyor belt 12 and the second conveyor belt 22, and the transmission roller 321 transmitting the power of the first belt conveyor 1 or the second belt conveyor 2 to the transition roller 31, makes the transition roller 31 rotate as a power roller, driving the cargo in contact with the power roller to move, so that the conveying speed of the cargo remains constant when passing through two adjacent belt conveyors, avoiding local accumulation of cargo, and ensuring the normal operation of the article conveying device. In addition, since the transition roller 31 does not require additional drive components such as motors, the equipment cost is reduced.
[0034] Optionally, in this embodiment, as Figure 2 and Figure 3 As shown, the drive roller 321 is connected to the first belt conveyor 1 and is used to transmit the power of the first belt conveyor 1 to the transition roller 31. Optionally, in this embodiment, the conveying surface of the first conveyor belt 12, the conveying surface of the second conveyor belt 22, and the highest point of the transition roller 31 together form the cargo conveying surface.
[0035] In this embodiment, as Figures 3-5 As shown, the transmission assembly 32 also includes a fixed frame 322, a movable frame 323, and an elastic element 324. The first belt conveyor 1 also includes a frame 13. The fixed frame 322 is fixedly connected to the frame 13, and the movable frame 323 is movably connected to the fixed frame 322 and can move relative to the fixed frame 322. The transmission roller 321 is supported by the movable frame 323 and can rotate about its own axis relative to the movable frame 323. The elastic element 324 is connected between the fixed frame 322 and the movable frame 323. The elastic force of the elastic element 324 is configured to ensure that the movable frame 323 always has a tendency to drive the transmission roller 321 to simultaneously abut against the first conveyor belt 12 and the transition roller 31. By setting the fixed frame 322, which is fixedly connected to the frame 13 of the first belt conveyor 1, the transmission assembly 32 can be modularized. Furthermore, the drive roller 321 is mounted on the movable frame 323, which is movable relative to the fixed frame 322, making the position of the drive roller 321 adjustable. When the relative position of the drive roller 321 and the first conveyor belt 12 changes due to processing errors, assembly errors, or other reasons, the position of the drive roller 321 is adjusted so that the drive roller 321 simultaneously engages with the first conveyor belt 12 and the transition roller 31. The movement of the first conveyor belt 12 drives the drive roller 321 to rotate, and the drive roller 321 drives the transition roller 31 to rotate. The elastic force of the elastic element 324 ensures that the drive roller 321 reliably abuts against the first conveyor belt 12 and the transition roller 31 and ensures sufficient pressure, thereby ensuring that the power of the first conveyor belt 12 is transmitted to the transition roller 31.
[0036] In this embodiment, as Figures 3-5As shown, the transition mechanism 3 also includes a base 33, the transition roller 31 is supported by the base 33, the transition roller 31 can rotate relative to the base 33 about its own axis, the base 33 is fixedly connected to the fixed frame 322, and the fixed frame 322 is provided with a guide groove 301; the transmission assembly 32 also includes a pivot shaft 325, the pivot shaft 325 is inserted into the guide groove 301 and can move along the guide groove 301; the movable frame 323 is sleeved on the pivot shaft 325, the movable frame 323 can rotate about the axis of the pivot shaft 325, and can move along the guide groove 301 with the pivot shaft 325. The guide groove 301 is configured such that when the movable frame 323 moves along the guide groove 301 with the pivot shaft 325, it can keep the drive roller 321 abutting against the transition roller 31 while keeping the drive roller 321 abutting against the first conveyor belt 12. The elastic element 324 is configured to provide elastic force to the movable frame 323 so that during the movement of the movable frame 323 along the extension direction of the guide groove 301 and the rotation about the axis of the pivot shaft 325, the movable frame 323 always has the tendency to drive the drive roller 321 to abut against the transition roller 31 and the first conveyor belt 12 at the same time. The above configuration integrates both the transmission assembly 32 and the transition roller 31 onto the base 33, making the transition mechanism 3 modular. When the transition mechanism 3 is not installed on the first belt conveyor 1, under the elastic force of the elastic element 324, the movable frame 323, carrying the transmission roller 321, abuts against the transition roller 31. When the transition mechanism 3 is installed on the frame 13 of the first belt conveyor 1, the first support roller 11 abuts against the transmission roller 321 across the first conveyor belt 12, driving the movable frame 323 to rotate around the pivot shaft 325 while moving along the guide groove 301 with the pivot shaft 325, and finally stabilizing in the state where the transmission roller 321 abuts against both the transition roller 31 and the first conveyor belt 12, ensuring that the power of the first conveyor belt 12 can be transmitted to the transition roller 31 through the transmission roller 321.
[0037] Optionally, such as Figures 3-6As shown, the centerline of the guide groove 301 is parallel to the line connecting the centers of the first support roller 11 and the transition roller 31. The guide groove 301 includes a first end and a second end. When the pivot shaft 325 is located at the first end, the movable frame 323 can rotate the transmission roller 321 around the pivot shaft 325 without abutting against the transition roller 31. When the pivot shaft 325 is located at the second end, the movable frame 323, under the action of the elastic element 324, moves the transmission roller 321 against the transition roller 31. Therefore, when assembling the transition mechanism 3, the pivot shaft 325 can be located at the first end first, and then the movable frame 323 can be rotated around the pivot shaft 325 so that the transmission roller 321 passes over the transition roller 31. Then, the pivot shaft 325 can be moved along the guide groove 301 to the second end, where the transmission roller 321 abuts against the transition roller 31 under the action of the elastic element 324. When the transition mechanism 3 is installed on the first belt conveyor 1, the pivot shaft 325 will move between the first end and the second end of the guide groove 301, and the drive roller 321 will simultaneously abut against the first conveyor belt 12 and the transition roller 31. In this embodiment, the drive roller 321 of the transmission assembly 32 is detachably connected to the first conveyor belt 12 of the first belt conveyor 1. After the first belt conveyor 1 and the second belt conveyor 2 are installed on the construction site, the transition mechanism 3 can be installed on the frame 13 of the first belt conveyor 1. Under the action of the elastic element 324, the drive roller 321 abuts against the transition roller 31, and the drive roller 321 also presses the first conveyor belt 12 onto the first support roller 11, thereby ensuring that the pressure between the drive roller 321 and the first conveyor belt 12 and the transition roller 31 is sufficient for the drive roller 321 to transmit the power of the first conveyor belt 12 to the transition roller 31.
[0038] In this embodiment, as Figure 5 and Figure 6 As shown, the transmission assembly 32 also includes a limiting post 326. The first end of the limiting post 326 is fixedly connected to one of the fixed frame 322 and the movable frame 323, and is spaced apart from the pivot shaft 325. The second end of the limiting post 326 is inserted into the other of the fixed frame 322 and the movable frame 323. The elastic element 324 is a compression spring, which is sleeved on the limiting post 326. The first end of the compression spring abuts against the fixed frame 322, and the second end abuts against the movable frame 323. By setting the limiting post 326 and sleeved the compression spring on it, loss of the compression spring can be prevented, ensuring the reliability of the transmission assembly 32. In other embodiments, the elastic element 324 is a torsion spring, which is sleeved on the pivot shaft 325. One torsion arm of the torsion spring is connected to the movable frame 323, and the other torsion arm is connected to the fixed frame 322. Optionally, in this embodiment, the first end of the limiting post 326 is fixedly connected to the movable frame 323, the fixed frame 322 has a limiting groove 302, and the second end of the limiting post 326 is inserted into the limiting groove 302 on the fixed frame 322.
[0039] In this embodiment, as Figure 4and Figure 7 As shown, the frame 13 includes two side plates 131 spaced apart from each other. The first support roller 11 is supported by the two side plates 131, and the base 33 is supported by the two side plates 131. The position of the base 33 relative to the side plates 131 along the cargo conveying direction is adjustable. This arrangement allows the position of the transition mechanism 3 along the cargo conveying direction to be adjusted, thereby ensuring that the transmission roller 321 can be reliably connected to the first support roller 11 or the first conveyor belt 12. Optionally, one of the side plates 131 and the base 33 is provided with a long groove 133 extending along the cargo conveying direction, and the other of the side plates 131 and the base 33 is provided with a fixing hole 331. Fasteners 35 pass through the long groove 133 and connect to the fixing hole 331. In this embodiment, the two side plates 131 are symmetrically provided with long grooves 133, and the two ends of the base 33 are correspondingly provided with fixing holes 331. Two fasteners 35 pass through the long grooves 133 on the two side plates 131 and are threadedly connected to the corresponding fixing holes 331.
[0040] Optionally, such as Figure 2 and Figure 7 As shown, the first belt conveyor 1 also includes a drive roller 14 and a motor (not shown). The first conveyor belt 12 is fitted onto the drive roller 14 and the first support roller 11. The position of the first support roller 11 relative to the side plate 131 along the cargo conveying direction is adjustable. The motor is connected to the drive roller 14 for driving the drive roller 14 to rotate. The rotation of the drive roller 14 drives the first conveyor belt 12 to move, and the first support roller 11 rotates accordingly. Because the position of the first support roller 11 relative to the side plate 131 along the cargo conveying direction is adjustable, it is easier to install the first conveyor belt 12.
[0041] Optionally, such as Figure 4 and Figure 7 As shown, the transition mechanism 3 includes multiple transmission components 32, which are arranged at intervals along the axial direction of the transition roller 31. Each transmission component 32's transmission roller 321 simultaneously abuts against both the first conveyor belt 12 and the transition roller 31, jointly transmitting the power of the first conveyor belt 12 to the transition roller 31, thereby ensuring the reliability of driving the transition roller 31. In this embodiment, the number of transmission components 32 can be determined based on the length of the transition roller 31.
[0042] In this embodiment, as Figure 4As shown, the transition mechanism 3 also includes two support arms 34, each with its first end fixedly connected to the base 33, and each with its second end having a slot 341. The transition roller 31 includes a spindle 311 and a roller 312. Both ends of the spindle 311 are inserted into the slots 341 of the two support arms 34, and the roller 312 is fitted onto the spindle 311 and can rotate around the axis of the spindle 311. Optionally, the slot 341 has an opening, through which the end of the spindle 311 enters the slot 341. The transition roller 31 also includes a limiting bolt 313, which is threaded to the support arm 34 and passes through the opening, preventing the spindle 311 from disengaging from the slot 341, thus facilitating the installation of the transition roller 31. Optionally, the transition roller 31 also includes two bearings (not shown in the figure), fitted onto the spindle 311 and inserted into the roller 312. By providing bearings, the rotation of the roller 312 becomes smoother.
[0043] Optionally, in other embodiments, the transmission assembly 32 further includes a meshing first gear and a second gear, with the first gear fixedly sleeved on the first support roller 11 and the second gear fixedly sleeved on the transmission roller 321. This arrangement allows the first support roller 11 to rotate, which in turn drives the transmission roller 321 to rotate via the meshing first and second gears. The transmission roller 321 then drives the transition roller 31 to rotate, transmitting the power from the first support roller 11 to the transition roller 31.
[0044] Example 2
[0045] The cargo conveying device provided in this embodiment is basically the same as that in Embodiment 1. The difference between the cargo conveying device provided in this embodiment and that in Embodiment 1 is as follows:
[0046] like Figure 8 As shown, in this embodiment, the transmission roller 321 is connected to the second belt conveyor 2 for transmitting the power of the second belt conveyor 2 to the transition roller 31.
[0047] Example 3
[0048] The cargo conveying device provided in this embodiment is basically the same as that in Embodiment 1. The difference between the cargo conveying device provided in this embodiment and that in Embodiment 1 is as follows:
[0049] like Figure 9As shown, the frame 13 is provided with a guide groove 132, which is an annular groove centered on the transition roller 31. The drive roller 321 is inserted into the guide groove 132. The transmission assembly 32 also includes an elastic element 324, which is connected between the drive roller 321 and the frame 13. The drive roller 321 abuts against the transition roller 31. The elastic force of the elastic element 324 is configured to ensure that the drive roller 321 always has a tendency to move along the guide groove 132 and abut against the first conveyor belt 12. Optionally, in this embodiment, the two side plates 131 are symmetrically provided with guide grooves 132, and the two ends of the drive roller 321 are inserted into the guide grooves 132 on the two side plates 131.
[0050] Example 4
[0051] like Figure 10 As shown, this embodiment also provides an article conveying device, which includes a first roller conveyor, a second roller conveyor, and a transition mechanism 3. The first roller conveyor and the second roller conveyor are arranged sequentially along the cargo conveying direction. The first roller conveyor includes a first roller 5, and the second roller conveyor includes a second roller 6. Along the cargo conveying direction, the first roller 5 and the second roller 6 are adjacent and spaced apart, and a connecting seam 4 is formed between them. The transition mechanism 3 includes a transition roller 31 and a transmission assembly 32. The transition roller 31 is rotatably installed in the connecting seam 4. The transmission assembly 32 includes a transmission roller 321, which abuts against the transition roller 31. The transmission roller 321 is also connected to the first roller 5 or the second roller 6 in a transmission manner. The transmission roller 321 is used to transmit the power of the first roller 5 or the second roller 6 connected to it to the transition roller 31. The conveying device provided in this embodiment uses a transition roller 31 at the joint 4 between the first roller 5 and the second roller 6. A drive roller 321 transmits power from the first roller 5 or the second roller 6 to the transition roller 31, causing the transition roller 31 to rotate as a power roller. This drives the movement of goods in contact with the power roller, ensuring a constant conveying speed for the goods as they pass through adjacent roller conveyors, preventing localized accumulation of goods, and guaranteeing the normal operation of the conveying device. Furthermore, since the transition roller 31 does not require an additional motor or other driving component, equipment costs are reduced. Optionally, in this embodiment, the drive roller 321 abuts against the first roller 5. The rotation of the first roller 5 drives the drive roller 321 to rotate synchronously, and the rotation of the drive roller 321 in turn drives the transition roller 31 to rotate, thereby achieving the transmission of power from the first roller to the transition roller 31.
[0052] In this embodiment, the first roller conveyor also includes a frame 13, such as Figure 10As shown, the frame 13 is provided with a guide groove 132, which is an annular groove with the transition roller 31 as the center; the transmission roller 321 is inserted into the guide groove 132, and the transmission assembly 32 also includes an elastic element 324, which is connected between the transmission roller 321 and the frame 13. The transmission roller 321 abuts against the transition roller 31, and the elastic force of the elastic element 324 is configured to make the transmission roller 321 always have a tendency to move along the guide groove 132 and abut against the first roller 5.
