Description

Technical Field

[0001] This application is applied to the field of automated conveying, and specifically relates to a transition conveying device for chain conveyors. Background Technology

[0002] Accumulating chain conveyors are commonly used automated conveying devices. In a conveying system, multiple accumulating chain conveyors are usually connected end to end to form a conveyor line of a certain length. At the junction of adjacent accumulating chain conveyors, there will be gaps between the chains. At the same time, the friction of the accumulating chain is low, and shorter pallets will have difficulty transitioning between adjacent accumulating chain conveyors, resulting in jamming. Summary of the Invention

[0003] In view of the above reasons, this application discloses a transition conveying device for chain conveyors. The transition device includes: a connecting bending plate, a transition base plate, a drive wheel, a free wheel, and a transmission belt. The transition base plate is disposed on one side of the connecting bending plate. Two free wheels are respectively disposed on the transition base plate through free wheel axles. The two free wheels are at the same vertical height. The drive wheel is disposed below the two free wheels. The transmission belt is sleeved on the two free wheels and the drive wheel. A first chain conveyor line and a second chain conveyor are connected end to end. The transition conveying device is disposed at the connection point of the first chain conveyor line and the second chain conveyor line. The drive wheel is connected to the drive end or driven end of the first chain conveyor line or the second chain conveyor line. The transmission belt between the two free wheels forms a transition conveying surface. The transition conveying surface is used to transitionally connect the conveying surfaces of the first chain conveyor line and the second chain conveyor line.

[0004] Preferably, if the drive wheel is connected to the drive end of the first chain conveyor line or the second chain conveyor line, the transmission shaft between the two drive ends passes through the drive wheel and drives the drive wheel to rotate through the drive end.

[0005] Preferably, if the drive wheel is connected to the driven end of the first chain conveyor or the second chain conveyor, a transition shaft is also included. The transition shaft passes through the drive shaft and is connected to the driven component of the driven end on one side, thereby driving the drive wheel to rotate through the driven end.

[0006] Preferably, it further includes a support plate, the connecting bending plate includes a horizontal connecting part and a vertical connecting part connected in sequence, the transition base plate is connected to the vertical connecting part, the support plate is connected to the horizontal connecting part, and the support plate is placed below the transmission belt between the two free wheels and abuts against the lower surface of the transmission belt.

[0007] Preferably, the support plate has downwardly extending latching portions at both ends, and the support plate is connected to the horizontal connecting portion through the latching portions.

[0008] Preferably, it further includes a tensioning assembly, which includes a tensioning plate and a tensioning wheel. The tensioning wheel is connected to the vertical connecting part through the tensioning plate, and the tensioning wheel abuts against the transmission belt.

[0009] Preferably, the tensioning plate includes a wheel connecting part, a plate connecting part, and a rotation adjustment part connected in sequence. The tensioning wheel is freely connected to the wheel connecting part. The plate connecting part is connected to the vertical connecting part through a connector. The rotation adjustment part has an arc-shaped groove. The connector passes through the arc-shaped groove and is connected to the vertical connecting part. By adjusting the position of the arc-shaped groove relative to the vertical connecting part, the tensioning wheel rotates around the plate connecting part, thereby adjusting the tension of the transmission belt.

[0010] Preferably, it further includes a protective component disposed on the connecting bending plate and covering the transition base plate, the drive wheel and the free wheel.

[0011] Preferably, the protective component includes a first protective plate and a second protective plate. The first protective plate is horizontally disposed on the connecting bending plate, and the second protective plate is vertically disposed on the opposite side of the vertical connecting part. The second protective plate has a first clearance portion at the drive wheel position, and the vertical connecting part has a second clearance portion at the drive wheel position.

[0012] Preferably, the connecting bending plate further includes a protective connecting portion located on the opposite side of the vertical connecting portion, and the second protective plate is connected to the protective connecting portion.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1 and Figure 2 As shown, the first chain conveyor line 1 and the second chain conveyor line 2 are connected end to end, that is, the driving end of the first chain conveyor 1 is connected to the driven end of the second chain conveyor 2, or the driven end of the first chain conveyor 1 is connected to the driving end of the second chain conveyor 2. Both the first chain conveyor line 1 and the second chain conveyor line 2 are accumulation chain conveyors. A transition conveying device 3 is provided at the junction of the first chain conveyor line 1 and the second chain conveyor line 2.

[0035] In some implementations, such as Figures 3 to 9The transition conveying device 3 shown has a transition base plate 5 on one side of the vertical portion of the connecting bending plate 12. Free wheel shafts 6 are respectively provided at both ends of the transition base plate 5. Free wheels 7 are sleeved on the free wheel shafts 6. The two free wheel shafts 6 have the same vertical height. The transition base plate 5 is a machined plate, which can ensure the installation accuracy of the free wheel shafts 6 and ensure that the two free wheels 7 have the same vertical height. At the same time, the processing requirements of the connecting bending plate 12 do not need to be too high, which can save certain costs. The drive wheel 8 is located below the two free wheels 7, forming an inverted triangular structure with the two free wheels 7. The transmission belt 9 is a toothed belt, which is sleeved on the two free wheels 7 and the drive wheel 8. The drive wheel 8 is driven by the drive end or driven end of the first chain conveyor line 1 or the second chain conveyor line 2, without the need for an additional motor or other additional power, thereby driving the transmission belt 9 to rotate. The transmission belt 9 between the two free wheels 7 forms a transition conveying surface, which can be used to connect the gap between the conveying surfaces of the first chain conveyor line 1 and the second chain conveyor line 2, so that the overall conveying surface is uninterrupted, allowing even small pallets to pass smoothly through the docking point via the transition conveying surface.

[0036] In some implementations, such as Figure 11 and Figure 12 As shown, the transition conveyor 3 is set at the drive end of the first chain conveyor line 1, and the connecting bending plate 12 is fixedly connected to the drive end on one side. The two drive ends are connected by a transmission shaft 10. The transmission shaft 10 passes through the drive wheel 8, so that the drive wheel 8 runs synchronously with the drive end, thereby driving the transmission belt 9 to run synchronously with the first chain conveyor line 1. It should be noted that it can also be set at the drive end of the second chain conveyor line 2. The first and second are only for reference and are not specific.

[0037] In some implementations, such as Figure 13 and Figure 14 As shown, the transition conveyor 3 is located at the driven end of the second chain conveyor 2. The connecting bending plate 12 is fixedly connected to the driven end on one side. One end of the transition shaft 11 passes through the drive wheel 8, and the other end of the transition shaft 11 passes through the driven component of the driven end on the same side. Specifically, the driven component can be a driven wheel, so that the drive wheel 8 runs synchronously with the driven end, thereby driving the transmission belt 9 to run synchronously with the second chain conveyor line 2. It should be noted that the transition conveyor 3 can also be located at the driven end of the first chain conveyor 1.

[0038] The location of the transition conveyor 3 can be determined according to the actual working conditions and set at either the driven end or the driving end of the chain conveyor line. If it is set at the driving end, the existing drive shaft 10 can be used without any additional components. If it is set at the driven end, a transition shaft 11 needs to be added.

[0039] In some implementations, such as Figures 6 to 9As shown, the connecting bending plate 12 is a metal bending plate, including a horizontal connecting part 1201 and a vertical connecting part 1202 connected in sequence. The transition plate 5 is connected to the vertical connecting part 1202. The other side of the vertical connecting part 1202 is fixedly connected to the opposite driving end or driven end. The support plate 13 is made of steel. The support plate 13 is set above the horizontal connecting part 1201 and below the transmission belt 9 between the two free wheels 7, that is, below the transmission belt 9 at the transition conveying surface position. The upper surface of the support plate 13 abuts against the lower surface of the transmission belt 9 at the transition conveying surface position, which plays a role in planar support for this part of the transmission belt, and at the same time plays a frictional role, ensuring the flatness of the transition conveying surface.

[0040] In some implementations, such as Figure 8 and Figure 9 As shown, the support plate 13 has downwardly extending latching portions 1301 at both ends, which are fastened to the two ends of the horizontal connecting portion 1201 for easy installation and replacement.

[0041] In some implementations, such as Figure 3 , Figure 4 and Figure 10 As shown, a tensioning assembly for adjusting the tension of the transmission belt is included, including a tensioning wheel 14 and a tensioning plate 15. The tensioning wheel 14 is connected to the vertical connecting part 1202 through the tensioning plate 15. The tensioning wheel 14 abuts against the transmission belt 9 between the drive wheel 8 and the free wheel on one side, and puts that section of the transmission belt 9 in a bent state.

[0042] In some implementations, such as Figure 3 , Figure 4 and Figure 10 As shown, the tensioning plate 15 includes a wheel connecting part 1501, a plate connecting part 1502, and a rotation adjustment part 1503 connected in sequence. The wheel connecting part 1501 is provided with a tensioning wheel shaft 16, and the tensioning wheel 14 is sleeved on the tensioning wheel shaft 16 and can rotate freely. A connecting member passes through the plate connecting part 1502 to connect the tensioning plate 15 to the vertical connecting part 1202. The connecting member can be a bolt. The rotation adjustment part 1503 has an arc groove 15031. The connecting member passes through the arc groove 15031 and connects to the vertical connecting part 1201. The tensioning plate 15 can rotate vertically around the plate connecting part 1502 with a limited range. The rotation angle is determined by the arc length of the arc groove 15031. After determining the rotation angle, the tensioning plate 15 can be fixed by tightening the bolt to fix the position of the tensioning wheel 14. If the position of the tensioning wheel 14 needs to be adjusted, it can be achieved by adjusting the position of the rotation adjustment part 1503.

[0043] In some implementations, such as Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 15As shown, the protective assembly is installed on the connecting bending plate 12 to cover components such as the transition base plate 5, drive wheel 8, and free wheel 7, thus providing protection against external debris and preventing internal friction dust from contaminating the external environment. The protective assembly includes a first protective plate 17 and a second protective plate 18. The first protective plate 17 is horizontally disposed at the lower end of the vertical connecting part 1202. The connecting bending part 12 also includes a protective connecting part 1203 located on the opposite side of the vertical connecting part 1202. The second protective plate 18 is vertically disposed on the opposite side of the protective connecting part 1203 of the vertical connecting part 1202. The second protective plate 18 has a first clearance part 1801 at the position of the drive wheel 8, and the vertical connecting part 1202 has a second clearance part 12021 at the position of the drive wheel. The first clearance part 1801 and the second clearance part 12021 provide clearance for the position of the drive shaft 10 or the transition shaft 11.
