Technical Field

[0001] This utility model relates to the technical field of shield tunnel segment production line, and in particular to a steel bar alignment conveyor roller. Background Technology

[0002] In the production of tunnel segments, straight steel bars are fed to a steel bar bending machine via a stepped feeding structure. The bending machine then processes the steel bars for the tunnel segment. In existing technology, bending production lines use a single conveyor roller to automatically feed a single steel bar. The bending machine can bend at least two steel bars simultaneously. However, when there are multiple steel bars (two or more), alignment cannot be achieved, requiring manual assistance. This limits production capacity, resulting in low efficiency, high labor intensity, and an inability to meet the production needs of a streamlined production line. Utility Model Content

[0003] The purpose of this invention is to provide a rebar alignment conveying roller conveyor to solve the problem of low production efficiency caused by the inability of multiple rebars to be automatically aligned and conveyed at the same time.

[0008] A pusher plate is slidably mounted on the frame. The rebar bending machine has a limiting structure. When the pusher plate pushes multiple rebars to slide along the first direction until the rebars abut against the limiting structure, the ends of the multiple rebars are aligned and one feeding is completed.

[0009] In some embodiments, the roller assembly includes a pair of fixed rollers and an adjusting roller, the adjusting roller being movable along a second direction to adjust the distance between the fixed rollers and the adjusting rollers, the second direction being perpendicular to the first direction.

[0011] In some embodiments, the rebar alignment conveyor rollers further include a transmission drive mechanism, which is mounted on the frame and is used to drive the pusher plate to slide along the first direction.

[0012] In some embodiments, the transmission drive mechanism includes a drive member, a drive sprocket, a driven sprocket, and a transmission chain sleeved on the drive sprocket and the driven sprocket. The output end of the drive member is connected to the drive sprocket. The drive sprocket and the driven sprocket are spaced apart on the frame along the first direction. One end of the push plate is fixedly connected to the transmission chain.

[0013] In some embodiments, the pusher plate is provided with a pushing portion that is higher than the highest point of the idler roller and is positioned directly opposite the ends of the plurality of reinforcing bars.

[0015] In some embodiments, the rebar alignment conveyor rollers further include sliding plates, and multiple sliding plates are provided. The multiple sliding plates are spaced apart on the frame along the first direction, and the rebar can fall into the roller assembly along the sliding plates.

[0016] In some embodiments, the sliding plate includes a guiding section and a limiting groove, wherein the width of the limiting groove along the second direction is less than 2D and greater than D, where D is the diameter of the reinforcing bar, and the reinforcing bar can enter the limiting groove along the guiding section.

[0017] The beneficial effects of this utility model are:

[0018] The steel bar alignment conveyor provided by this utility model, by setting up a roller group, can clamp multiple steel bars at the same time and make the center lines of the multiple steel bars aligned in a vertical plane; when the push plate pushes the multiple steel bars to the point where the multiple steel bars abut against the limiting structure on the steel bar bending machine, the multiple steel bars achieve end alignment between the push plate and the limiting structure, thereby solving the problem that multiple steel bars cannot be automatically aligned and conveyed at the same time, which is conducive to improving production efficiency, reducing manual labor intensity, and meeting the production capacity needs of the shield tunnel segment production line.

[0032] This utility model embodiment provides a steel bar alignment conveying roller conveyor, such as Figure 1 and Figure 2 As shown, a stepped feeding mechanism 2 and a rebar bending machine 3 are arranged between them. The stepped feeding mechanism 2 and the rebar alignment conveying roller 1 are arranged along the first direction (X direction) at the front end of the rebar bending machine 3 to feed multiple rebars 100. The stepped feeding mechanism 2 and the rebar alignment conveying roller 1 are arranged side by side. Multiple rebars 100 on the stepped feeding mechanism 2 are fed to the rebar alignment conveying roller 1 along the second direction (Y direction). The rebar alignment conveying roller 1 aligns the two ends of the multiple rebars 100 along the first direction and conveys them to the rebar bending machine 3. The following describes the rebar alignment conveying roller 1 provided by this utility model in detail using the alignment conveying of two rebars 100 as an example.

[0033] like Figures 3-5 As shown, the rebar alignment conveyor 1 includes a frame 11, roller sets 12, and a pusher plate 13. Multiple idler rollers 111 are spaced apart along a first direction on the frame 11 to support the rebars 100, and the long axis of the rebars 100 is arranged along the first direction. Multiple roller sets 12 are provided, and multiple roller sets 12 are spaced apart along the first direction on the frame 11 to clamp the rebars 100. The center lines of the multiple rebars 100 clamped in each roller set 12 are located in the same vertical plane. The pusher plate 13 is slidably arranged on the frame 11. The rebar bending machine 3 has a limiting structure 31. When the pusher plate 13 pushes multiple rebars 100 to slide along the first direction until the rebars 100 abut against the limiting structure 31, the two ends of the multiple rebars 100 are aligned and one feeding is completed.

[0034] like Figure 3 As shown, the frame 11 extends along a first direction (X direction), and multiple idler rollers 111 are spaced apart above the frame 11 along the first direction. Multiple roller sets 12 are also spaced apart above the frame 11 along the first direction. Preferably, the idler rollers 111 and roller sets 12 are alternately arranged. It can be understood that the roller shafts of the idler rollers 111 are arranged along a second direction, and the roller sets 12 are arranged vertically along their shafts. Both the first and second directions are horizontal and perpendicular to each other. When two steel bars 100 are clamped within the multiple roller sets 12, the center lines of the two steel bars 100 are located in the same vertical plane, meaning the two steel bars 100 overlap vertically. By arranging the roller sets 12 to clamp the two steel bars 100 in the same vertical plane, it is beneficial for the two steel bars 100 to simultaneously enter the steel bar bending machine 3 for synchronous bending operations in the vertical direction, thus improving operating efficiency. It should be noted that the length of the frame 11 along the first direction is greater than the length of the steel bar 100, so that the steel bar 100 can be fed forward under the action of the push plate 13.

[0035] The rebar alignment conveyor 1 provided by this utility model, by setting multiple roller groups 12, can simultaneously clamp multiple rebars 100 and align the center lines of the multiple rebars 100 in a vertical plane. When the push plate 13 pushes the multiple rebars 100 until they abut against the limiting structure 31 on the rebar bending machine 3, the multiple rebars 100 achieve end-to-end alignment between the push plate 13 and the limiting structure 31, thereby solving the problem that multiple rebars 100 cannot be automatically aligned and conveyed simultaneously. This is beneficial for improving production efficiency, reducing manual labor intensity, and meeting the production capacity needs of the shield tunnel segment production line. It should be noted that the limiting structure 31 on the rebar bending machine 3 is existing technology, which is a limiting structure 31 for the rebars 100 in place. This utility model uses the push plate 13 in combination with the limiting structure 31 to achieve end-to-end alignment of the rebars 100.

[0036] In some embodiments, the roller assembly 12 includes a pair of fixed rollers 121 and an adjusting roller, the adjusting roller being movable along a second direction to adjust the distance between the fixed rollers 121 and the adjusting roller, the second direction being perpendicular to the first direction.

[0037] like Figures 3-5Each roller assembly 12 includes a fixed roller 121 and an adjusting roller. The position of the adjusting roller is adjustable in the second direction, so that the distance between the fixed roller 121 and the adjusting roller can be adjusted according to the diameter D of the steel bar 100. The roller shafts of both the fixed roller 121 and the adjusting roller are set in the vertical direction, thereby realizing the rolling connection between the steel bar 100 and the roller assembly 12. When the steel bar 100 moves in the first direction, the roller assembly 12 clamps two steel bars 100 stacked in the vertical direction for rolling transmission, ensuring that the two steel bars 100 are always in the same vertical plane for movement, which is beneficial for the push plate 13 to always push the two steel bars 100 forward.

[0038] In some embodiments, there are two types of adjusting rollers: a manual adjusting roller 122 and an automatic adjusting roller 123. The manual adjusting roller 122 is located on the frame 11 at one end away from the rebar bending machine 3, and the automatic adjusting roller 123 is located on the frame 11 at the other end facing the rebar bending machine 3.

[0039] like Figure 4 As shown, the roller of the manual adjustment roller 122 is rotatably connected to the slide plate. The slide plate is slidably mounted on the base plate. A screw is threadedly connected to the base plate. The end of the screw is movably connected to the drive plate. The drive plate is connected to the slide plate. When the screw rotates relative to the base plate, it drives the drive plate to slide the slide plate on the base plate in the second direction to achieve position adjustment.

[0040] Compared to the manually adjustable roller 122, the automatic adjusting roller 123 uses an electric drive mechanism instead of a screw to move the drive plate. The automatic adjusting roller 123, compared to the manually adjustable roller 122, is as follows: Figure 3 As shown, along the first direction, multiple manually adjustable rollers 122 are arranged at one end away from the rebar bending machine 3, and multiple automatically adjustable rollers 123 are arranged at the other end facing the rebar bending machine 3, forming multiple sets of manual rollers and multiple sets of automatic rollers respectively. During the alignment and conveying process of the rebar 100, the distance L1 between the manually adjustable roller 122 and the fixed roller 121 in the same group is greater than the distance L2 between the automatically adjustable roller 123 and the fixed roller 121 in the same group. As the push plate 13 pushes the rebar 100 to move, the two rebars 100 have a certain degree of freedom of movement when they start to move, so they can initially align their ends. When they are about to reach the rebar bending machine 3, the automatically adjustable roller 123 and the fixed roller 121 in the same group clamp the two rebars 100 to ensure that the relative position of the two rebars 100 remains unchanged until the ends of the two rebars 100 abut against the limiting structure 31 on the rebar bending machine 3. Under the action of the push plate 13 and the limiting structure 31, the multiple rebars 100 achieve the final alignment of their ends.

[0041] In some embodiments, the rebar alignment conveying roller 1 further includes a transmission drive mechanism 14, which is mounted on the frame 11 and is used to drive the push plate 13 to slide along a first direction.

[0042] By setting up a transmission drive mechanism 14 to drive the movement of the push plate 13, manual labor can be saved and automatic control of the push plate 13 can be achieved, thereby improving feeding efficiency and the accuracy of the direction of movement of the push plate 13, and ensuring the smooth progress of the feeding process.

[0043] In some embodiments, the transmission drive mechanism 14 includes a drive member, a drive sprocket 141, a driven sprocket 142, and a transmission chain 143 sleeved on the drive sprocket 141 and the driven sprocket 142. The output end of the drive member is connected to the drive sprocket 141. The drive sprocket 141 and the driven sprocket 142 are spaced apart on the frame 11 along a first direction. One end of the push plate 13 is fixedly connected to the transmission chain 143.

[0044] In this embodiment, as Figure 3 As shown, when the movement distance of the push plate 13 is large, one or more driven sprockets 142 can be selected. In this embodiment, a drive sprocket 141 and two driven sprockets 142 are provided on one side of the frame 11. The conveyor chain 143 is sleeved on the drive sprocket 141 and the driven sprockets 142. The drive component drives the rotation of the drive sprocket 141, which in turn drives the transmission of the conveyor chain 143, thereby driving the push plate 13 to push the steel bar 100 to move. After the feeding is completed, the drive component drives the drive sprocket 141 in the opposite direction to move the push plate 13 to the initial position, ready for the next feeding. The electric drive mechanism and drive component can be motors.

[0045] In some embodiments, the pusher plate 13 is provided with a pushing part 131, which is higher than the highest point of the idler roller 111 and is disposed directly opposite the ends of the plurality of reinforcing bars 100.

[0046] like Figure 4 As shown, the body of the push plate 13 is slidably disposed on one side of the frame 11, and the pushing part 131 is located above the frame 11 and suspended above the idler roller 111. When multiple steel bars 100 are supported on the idler roller 111, the pushing part 131 can push the ends of the steel bars 100 to push the steel bars 100 to move along the first direction. Under the action of the friction between the steel bars 100, the friction between the steel bars 100 and the roller assembly 12, and the pushing force of the push plate 13, two steel bars 100 move along the first direction. The pushing part 131 always advances in the vertical direction where the center line of the two steel bars 100 is located, ensuring that it can push the ends of the steel bars 100. In order for the smooth movement of the push plate 13, the distance between the bottom end of the pushing part 131 and the highest point of the idler roller 111 is not greater than D / 2.

[0047] In some embodiments, one of the frame 11 and the push plate 13 is provided with a slide rail 112 and the other is provided with a slider 132, and the slider 132 is slidably fitted with the slide rail 112.

[0048] like Figure 4 In the embodiment shown, the side of the frame 11 is provided with a slide rail 112, and the main body of the push plate 13 is provided with a slider 132. The slider 132 is slidably installed with the slide rail 112. When the conveyor chain 143 drives the push plate 13 to move, the slider 132 moves along the slide rail 112 to achieve the directional guidance of the push plate 13.

[0049] In some embodiments, the rebar alignment conveying roller 1 further includes a sliding plate 15, and multiple sliding plates 15 are provided. The multiple sliding plates 15 are spaced apart on the frame 11 along a first direction, and the rebar 100 can fall into the roller group 12 along the sliding plate 15.

[0050] like Figure 3 As shown, multiple sliding plates 15 are spaced apart along the first direction on the frame 11. When each steel bar 100 enters the steel bar alignment conveyor roller table 1 from the stepped feeding mechanism 2, as... Figure 2 Under the sliding support and guidance of multiple sliding plates 15, the steel bars 100 enter the roller group 12. It can be understood that the sliding plates 15 are used to connect the stepped feeding mechanism 2 and the steel bar alignment conveying roller 1, so as to realize the feeding of multiple steel bars 100 to the steel bar alignment conveying roller 1.

[0051] In some embodiments, the sliding plate 15 includes a guiding section 151 and a limiting groove 152. The width of the limiting groove 152 along the second direction is less than 2D and greater than D, where D is the diameter of the reinforcing bar 100. The reinforcing bar 100 can enter the limiting groove 152 along the guiding section 151.

[0052] like Figure 2 and Figure 5 The sliding plate 15 is fixed to the frame 11. Guide sections 151 are provided at both ends of the sliding plate 15 along the second direction. The top of the guide section 151 is higher than the roller assembly 12 to prevent the reinforcing bar 100 from hitting the roller assembly 12 during its descent. A limiting groove 152 is provided between the two guide sections 151 on both sides. The width of the limiting groove 152 along the second direction is less than 2D and greater than D, allowing the two reinforcing bars 100 falling sequentially to overlap vertically. The bottom of the limiting groove 152 is lower than the highest point of the idler roller 111, ensuring that the reinforcing bar 100 can only be supported on the idler roller 111 after falling into the limiting groove 152, facilitating the movement of the reinforcing bar 100. The guide section 151 extends upward from one end of the limiting groove 152 toward the side away from the limiting groove 152, such as... Figure 2 The material guide section 151 and the discharge plate of the stepped feeding mechanism 2 have the same material guide angle, so that the steel bar 100 can slide stably from the discharge plate to the material guide section 151 and enter the limiting groove 152.

[0053] The rebar alignment and conveying roller conveyor 1 provided by this utility model includes the following steps in the rebar alignment and conveying process:

[0054] S1, slide the push plate 13 to one end of the frame 11 away from the rebar bending machine 3, and multiple rebars 100 are supported on multiple idler rollers 111; as Figure 3 As shown, two steel bars 100 are stacked vertically.

[0055] S2, the roller assembly 12 is adjusted to clamp multiple reinforcing bars 100 and ensure that the center lines of the multiple reinforcing bars 100 are located in the same vertical plane; wherein, the distance between the manually adjusting roller 122 and the fixed roller 121 of the same assembly is slightly larger than the diameter D of the reinforcing bar 100, so that the two reinforcing bars 100 move synchronously in the vertical plane and may generate a certain relative movement for end alignment; when the end of the reinforcing bar 100 moves between the automatically adjusting roller 123 and the fixed roller 121 of the same assembly, the automatically adjusting roller 123 adjusts the clamping distance along the second direction, so that the reinforcing bar 100 can be tightly clamped between the automatically adjusting roller 123 and the fixed roller 121 of the same assembly, ensuring the synchronous movement of the two reinforcing bars 100 and ensuring that the center lines of the two reinforcing bars 100 are always located in the same vertical plane.

[0056] S3, the pusher plate 13 pushes multiple steel bars 100 to slide along the first direction until the steel bars 100 abut against the limiting structure 31 on the steel bar bending machine 3, and the two ends of the multiple steel bars 100 are aligned and one feeding is completed.

[0057] If either of the reinforcing bars 100 fails to engage with the limiting structure 31, the push plate 13 continues to move until both reinforcing bars 100 engage with the limiting structure 31, aligning the two ends of the two reinforcing bars 100 and ensuring both reinforcing bars 100 are in place. The push plate 13 is then driven to move in the opposite direction to the end of the frame 11 away from the reinforcing bar bending machine 3, preparing for the next feeding.

[0058] In the above-mentioned process of aligning and conveying reinforcing bars, the push plate 13 is first slid to one end away from the reinforcing bar bending machine 3. When multiple reinforcing bars 100 are simultaneously clamped in multiple roller groups 12 and the center lines of multiple reinforcing bars 100 are located in the same vertical plane, the push plate 13 slides along the frame 11 and pushes the multiple reinforcing bars 100 to move. When the reinforcing bars 100 abut against the limiting structure 31 set on the reinforcing bar bending machine 3, the two ends of the multiple reinforcing bars 100 are aligned, and the feeding of reinforcing bars 100 is realized in one go. This solves the problem that multiple reinforcing bars 100 cannot be automatically aligned and conveyed at the same time. Multiple reinforcing bars 100 can be bent simultaneously on the reinforcing bar bending machine 3, which is conducive to improving production efficiency, reducing manual labor intensity, and meeting the production needs of the shield tunnel segment production line.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
