In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] The embodiment of the present invention provides a steel bar alignment conveyor roller, such as Figure 1 and Figure 2 As shown, it is arranged between the step feeding mechanism 2 and the steel bar bending machine 3, wherein the step feeding mechanism 2 and the steel bar alignment conveying roller 1 are arranged at the front end of the steel bar bending machine 3 along the first direction (X direction) to feed multiple steel bars 100, and the step feeding mechanism 2 and the steel bar alignment conveying roller 1 are arranged side by side; the multiple steel bars 100 on the step feeding mechanism 2 are fed to the steel bar alignment conveying roller 1 along the second direction (Y direction), and the steel bar alignment conveying roller 1 aligns the two ends of the multiple steel bars 100 along the first direction and conveys them to the steel bar bending machine 3. The steel bar alignment conveying roller 1 provided by the present invention is described in detail below taking the alignment and conveying of two steel bars 100 as an example.

[0038] like Figure 3-Figure 5 As shown, the steel bar alignment conveyor roller 1 includes a frame 11, a roller group 12 and a push plate 13. A plurality of rollers 111 are arranged on the frame 11 along a first direction to support the steel bar 100, and the long axis of the steel bar 100 is arranged along the first direction; a plurality of roller groups 12 are provided, and a plurality of roller groups 12 are arranged on the frame 11 along the first direction to clamp the steel bar 100, and the center lines of the plurality of steel bars 100 clamped in each roller group 12 are located in the same vertical plane; the push plate 13 is slidably arranged on the frame 11, and the steel bar bending machine 3 has a limiting structure 31. When the push plate 13 pushes the plurality of steel bars 100 to slide along the first direction until the steel bars 100 abut against the limiting structure 31, the two ends of the plurality of steel bars 100 are aligned and one feeding is completed.

[0039] like Figure 3 As shown, the frame 11 is extended along the first direction (X direction), a plurality of rollers 111 are arranged above the frame 11 at intervals along the first direction, and a plurality of roller groups 12 are arranged above the frame 11 at intervals along the first direction. Preferably, the rollers 111 and the roller groups 12 are arranged alternately. It can be understood that the rollers 111 are arranged along the second direction, and the roller groups 12 are arranged along the vertical direction. The first direction and the second direction are both in the horizontal direction and perpendicular to each other. When two steel bars 100 are clamped in the plurality of roller groups 12, the center lines of the two steel bars 100 are located in the same vertical plane, that is, the two steel bars 100 overlap in the vertical direction. By setting the roller group 12 to clamp the two steel bars 100 in the same vertical plane, it is beneficial for the two steel bars 100 to enter the steel bar bending machine 3 in the vertical direction at the same time for synchronous bending operation, thereby improving the operation 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 advanced and loaded under the action of the push plate 13.

[0040] The steel bar alignment conveying roller 1 provided by the present invention can clamp multiple steel bars 100 at the same time and align the center lines of multiple steel bars 100 in a vertical plane by setting multiple roller groups 12; when the push plate 13 pushes multiple steel bars 100 until multiple steel bars 100 abut against the limiting structure 31 on the steel bar bending machine 3, multiple steel bars 100 are aligned at both ends between the push plate 13 and the limiting structure 31, thereby solving the problem that multiple steel bars 100 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 needs of shield segment assembly line capacity. It should be noted that the limiting structure 31 on the steel bar bending machine 3 is a prior art. When the limiting structure 31 is in place after the steel bar 100 is loaded, the present invention uses the push plate 13 in combination with the limiting structure 31 to achieve alignment of the two ends of the steel bar 100.

[0041] In some embodiments, the roller assembly 12 includes a fixed roller 121 and an adjusting roller arranged in pairs, and the adjusting roller can move along the second direction to adjust the distance between the fixed roller 121 and the adjusting roller, and the second direction is perpendicular to the first direction.

[0042] like Figure 3-Figure 5 Each roller group 12 includes a fixed roller 121 and an adjusting roller. The position of the adjusting roller in the second direction is adjustable, so that the spacing 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 the fixed roller 121 and the adjusting roller are both arranged in the vertical direction, thereby realizing the rolling connection between the steel bar 100 and the roller group 12. When the steel bar 100 moves along the first direction, the roller group 12 clamps the two steel bars 100 stacked in the vertical direction for rolling transmission, ensuring that the two steel bars 100 are always located in the same vertical plane for movement, which is beneficial for the push plate 13 to always push the two steel bars 100 forward.

[0043] In some embodiments, there are two types of adjusting rollers, namely a manual adjusting roller 122 and an automatic adjusting roller 123. The manual adjusting roller 122 is arranged on one end of the frame 11 away from the steel bar bending machine 3, and the automatic adjusting roller 123 is arranged on the other end of the frame 11 facing the steel bar bending machine 3.

[0044] like Figure 4 As shown, the roller of the manual adjustment roller 122 is rotatably connected to the skateboard, the skateboard is slidably installed on the base plate, the 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 skateboard, when the screw rotates relative to the base plate, the drive plate is driven to drive the skateboard to slide on the base plate along the second direction to achieve position adjustment.

[0045] Compared with the manual adjustment roller 122, the automatic adjustment roller 123 uses an electric drive mechanism instead of a screw to drive the movement of the drive plate. Figure 3 As shown, along the first direction, a plurality of manual adjustment rollers 122 are arranged at one end away from the steel bar bending machine 3, and a plurality of automatic adjustment rollers 123 are arranged at the other end toward the steel bar bending machine 3, so as to form a plurality of manual roller groups and a plurality of automatic roller groups respectively. In the process of aligning and conveying the steel bars 100, the spacing L1 between the manual adjustment roller 122 and the fixed roller 121 of the same group is greater than the spacing L2 between the automatic adjustment roller 123 and the fixed roller 121 of the same group. Then, in the process of the push plate 13 pushing the steel bars 100 to move, the two steel bars 100 have a certain degree of freedom of movement when they start to move, so that the two ends can be initially aligned. When they are about to reach the steel bar bending machine 3, the automatic adjustment roller 123 and the fixed roller 121 of the same group clamp the two steel bars 100 to ensure that the relative positions of the two steel bars 100 remain unchanged, until the ends of the two steel bars 100 abut against the limiting structure 31 on the steel bar bending machine 3, and the plurality of steel bars 100 are finally aligned at both ends under the action of the push plate 13 and the limiting structure 31.

[0046] In some embodiments, the steel bar alignment conveyor roller 1 further includes a transmission drive mechanism 14 , which is disposed on the frame 11 , and is used to drive the push plate 13 to slide along the first direction.

[0047] By setting up a transmission drive mechanism 14 to drive the movement of the push plate 13, labor can be saved, and it is conducive to realizing automatic control of the push plate 13, improving the feeding efficiency and the directional accuracy of the movement of the push plate 13, ensuring the smooth progress of the feeding process.

[0048] In some embodiments, the transmission drive mechanism 14 includes a driving member, a driving sprocket 141, a driven sprocket 142 and a transmission chain 143 mounted on the driving sprocket 141 and the driven sprocket 142. The output end of the driving member is connected to the driving sprocket 141. The driving 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.

[0049] In this embodiment, Figure 3As shown, when the movement distance of the push plate 13 is large, more than one driven sprocket 142 can be selected. In this embodiment, a driving sprocket 141 and two driven sprockets 142 are provided on one side of the frame 11, and a transmission chain 143 is sleeved on the driving sprocket 141 and the driven sprocket 142. The driving sprocket 141 is driven by the driving member to rotate, which drives the transmission chain 143, and then drives the push plate 13 to push the steel bar 100 to move; after the loading is completed, the driving member drives the driving sprocket 141 in the reverse direction to move the push plate 13 to the initial position, ready for the next loading. The electric drive mechanism and the driving member can use a motor.

[0050] In some embodiments, the push plate 13 is provided with a push portion 131 , which is higher than the highest point of the roller 111 and is disposed directly facing the ends of the plurality of steel bars 100 .

[0051] like Figure 4 As shown, the body of the push plate 13 is slidably disposed on one side of the frame 11, and the push portion 131 is located above the frame 11 and suspended above the roller 111. When multiple steel bars 100 are supported on the roller 111, the push portion 131 can push the ends of the steel bars 100 to push the steel bars 100 to move along the first direction. Under the friction between the steel bars 100, the friction between the steel bars 100 and the roller group 12, and the thrust of the push plate 13, the two steel bars 100 move along the first direction, and the push portion 131 always moves in the vertical plane where the center lines of the two steel bars 100 are located, ensuring that the ends of the steel bars 100 can be pushed. In order to ensure the smooth movement of the push plate 13, the distance between the bottom end of the push portion 131 and the highest point of the roller 111 is not greater than D / 2.

[0052] 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 installed in a sliding cooperation with the slide rail 112 .

[0053] like Figure 4 In the illustrated embodiment, a slide rail 112 is provided on the side of the frame 11, and a slider 132 is provided on the main body of the push plate 13. The slider 132 is slidably installed with the slide rail 112. When the transmission chain 143 drives the push plate 13 to move, the slider 132 moves along the slide rail 112 to achieve a directional guiding effect on the push plate 13.

[0054] In some embodiments, the steel bar alignment conveyor roller 1 further includes a sliding plate 15 , and a plurality of sliding plates 15 are provided. The plurality of sliding plates 15 are spaced apart on the frame 11 along a first direction, and the steel bar 100 can fall into the roller assembly 12 along the sliding plates 15 .

[0055] like Figure 3 As shown, a plurality of sliding plates 15 are arranged on the frame 11 at intervals along the first direction. When each steel bar 100 enters the steel bar alignment conveying roller 1 from the step feeding mechanism 2, as shown in FIG. Figure 2 , enters between the roller group 12 under the sliding support and guiding action of multiple sliding plates 15. It can be understood that the sliding plate 15 is used to connect the step feeding mechanism 2 and the steel bar alignment conveying roller 1 to realize the feeding of multiple steel bars 100 to the steel bar alignment conveying roller 1.

[0056] In some embodiments, the sliding plate 15 includes a guide portion 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, D is the diameter of the steel bar 100 , and the steel bar 100 can enter the limiting groove 152 along the guide portion 151 .

[0057] like Figure 2 and Figure 5 The sliding plate 15 is fixed on the frame 11, and guide parts 151 are provided at both ends of the sliding plate 15 along the second direction. The top height of the guide part 151 is higher than the roller group 12 to prevent the steel bar 100 from hitting the roller group 12 during the sliding process. A limiting groove 152 is provided between the two guide parts 151 on both sides. The width of the limiting groove 152 along the second direction is less than 2D and greater than D, so that the two steel bars 100 that are dropped successively can overlap in the vertical direction. The bottom of the limiting groove 152 is lower than the highest end of the roller 111, so that the steel bar 100 can only be supported on the roller 111 after falling into the limiting groove 152, which is convenient for the movement of the steel bar 100. The guide part 151 extends from one end of the limiting groove 152 toward the upper side away from the limiting groove 152, such as Figure 2 The material guiding portion 151 and the material discharging plate of the step feeding mechanism 2 have the same material guiding angle, so that the steel bar 100 can stably slide from the material discharging plate to the material guiding portion 151 and enter the limiting groove 152.

[0058] The present invention also provides a method for aligning and conveying steel bars. The steel bar aligning and conveying roller 1 provided by the present invention is used. The method for aligning and conveying steel bars comprises the following steps:

[0059] S1, slide the push plate 13 to one end of the frame 11 away from the steel bar bending machine 3, and multiple steel bars 100 are supported on multiple rollers 111; Figure 3 In the state shown, two steel bars 100 are stacked vertically.

[0060] S2, adjusting the roller group 12 to clamp multiple steel bars 100 and make the center lines of the multiple steel bars 100 located in the same vertical plane; wherein, the spacing between the manually adjustable roller 122 and the fixed roller 121 of the same group is slightly larger than the diameter D of the steel bar 100, so that the two steel bars 100 move synchronously in the vertical plane and may produce a certain relative movement to align the ends; when the end of the steel bar 100 moves between the automatic adjusting roller 123 and the fixed roller 121 of the same group, the automatic adjusting roller 123 adjusts the clamping distance along the second direction, so that the steel bar 100 can be tightly clamped between the automatic adjusting roller 123 and the fixed roller 121 of the same group, ensuring the synchronous movement of the two steel bars 100 and ensuring that the center lines of the two steel bars 100 are always located in the same vertical plane.

[0061] S3, the push plate 13 pushes the 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.

[0062] If any one of the steel bars 100 does not abut against the limiting structure 31, the push plate 13 continues to move until both steel bars 100 abut against the limiting structure 31, the two ends of the two steel bars 100 are aligned, and both steel bars 100 are loaded in place. The push plate 13 is driven to move in the opposite direction to the end of the frame 11 away from the steel bar bending machine 3, ready for the next loading.

[0063] The steel bar alignment and conveying method provided by the present invention first slides the push plate 13 to one end away from the steel bar bending machine 3. When multiple steel bars 100 are clamped in multiple roller groups 12 at the same time and the center lines of the multiple steel bars 100 are located in the same vertical plane, the push plate 13 slides along the frame 11 and pushes the multiple steel bars 100 to move. When the steel bars 100 abut against the limiting structure 31 provided on the steel bar bending machine 3, the two ends of the multiple steel bars 100 are aligned, and the steel bars 100 are fed at one time, thereby solving the problem that multiple steel bars 100 cannot be automatically aligned and conveyed at the same time. Multiple steel bars 100 can be bent synchronously on the steel bar bending machine 3, which is conducive to improving production efficiency, reducing manual labor intensity, and meeting the production needs of the shield segment assembly line capacity.

[0064] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
