Description

Technical Field

[0001] This invention relates to the field of steel bar processing technology, specifically to a flattening mechanism and a steel bar picking device. Background Technology

[0002] Rebar raw materials are generally delivered in whole bundles, with specifications ranging from Φ12 to 40mm and lengths from 6 to 12m. In actual use, the rebar needs to be picked up according to requirements and sent to cutting equipment to be cut to the required length. When picking up rebar, it is first placed in the raw material silo. Currently, rebar picking mainly uses the following three methods:

[0003] The first method is the traditional manual picking and feeding method. Operators sort the steel bars according to specifications, and then feed them into the cutting equipment for processing according to the needs. This method has low processing efficiency, high cost, and high labor intensity, and requires 1 to 2 people to complete.

[0004] The second type: such as Figure 1 As shown, the reinforcing bars 3' are placed horizontally. Magnet 2' is used to pick up multiple reinforcing bars at once and raise them to a certain height. Then, gripper 1' uses a horizontal gripper to pick up one reinforcing bar 3' and transport it to the processing equipment. When picking up the second reinforcing bar 3', an additional sensor or visual judgment is needed to determine its position. Gripper 1' needs to pick up the second reinforcing bar based on the detection result. If it cannot be picked up, magnet 2' needs to descend again to pick up the reinforcing bar. Although this method achieves automation, it is inefficient, and situations where it cannot pick up a small number of reinforcing bars may occur.

[0005] The third method is automated feeding, which uses a magnet to pick up multiple steel bars at once, lifts them to a certain height and places them on a receiving rod, and uses grippers to pick them up one by one in turn. This method is highly efficient, but the steel bars may stack when placed, making it impossible for the grippers to pick them up accurately. In addition, the spacing between the steel bars is inconsistent, so additional assistance such as vision or sensors is required for the picking.

[0006] Therefore, it is necessary to propose an improved rebar picking device to solve the above-mentioned technical problems. Summary of the Invention

[0020] Optionally, the thickness direction of the rubbing plate is consistent with the axial direction of the reinforcing bar; after the rubbing plate flattens the reinforcing bar, it maintains a preset distance from the upper surface of the reinforcing bar to prevent the reinforcing bar from being stacked again, and exposes the reinforcing bar located at the clamping position on the receiving mechanism.

[0021] Optionally, the flat plate includes a flattening portion and a connecting portion that are perpendicular to each other.

[0026] A clamping mechanism is fixed on the support mechanism and located above the receiving mechanism. The clamping mechanism clamps the steel bar located at the clamping position on the receiving rod and conveys it to the next process.

[0027] The aforementioned flattening mechanism is located on one side of the receiving mechanism. The flattening mechanism repeatedly flattens the steel bars stacked on the receiving rod into a single layer.

[0028] A positioning mechanism is located on one side of the receiving mechanism, away from the clamping position.

Detailed Implementation

[0057] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0058] Reference Figure 2The smoothing mechanism provided in one embodiment of the present invention includes a bracket 103, a guide rail, a movable plate 108, a first servo motor-reducer assembly 101, a second servo motor-reducer assembly 102, a first gear 104, a first rack 105, a second gear 113, a second rack 114, a third guide rail 109, a first cylinder 111, and a smoothing plate 112. The bracket 103 serves as the mounting base for the smoothing mechanism and provides support for it. The guide rail is fixed to the bracket 103 and extends along the smoothing mechanism 100. The height direction is also the stacking direction of the reinforcing bars on the receiving mechanism; one side of the movable plate 108 is fixed to the slider of the guide rail; the first servo motor-reducer assembly 101 and the second servo motor-reducer assembly 102 are both fixed to the movable plate 108, with the first servo motor-reducer assembly 101 located below the second servo motor-reducer assembly 102; the first gear 104 is connected to the output shaft of the second servo motor-reducer assembly 102; the second gear 113 is connected to the output shaft of the first servo motor-reducer assembly 101. The first rack 105 is set along the height direction of the smoothing mechanism 100, and is fixed on the bracket 103 and cooperates with the first gear 104. When the servo motor of the second servo motor-reducer combination 102 rotates, it drives the movable plate 108 to move up and down along the first rack 105. The third guide rail 109 is located on the other side of the movable plate 108, and is perpendicular to the guide rail. The slider of the third guide rail 109 is provided with a rack mounting plate 110. The second rack 114 is fixed on the rack mounting plate 110. The second rack 114 is perpendicular to the first rack 105. The second rack 114 and the second gear 113 cooperate with each other. When the servo motor of the first servo motor-reducer combination 101 rotates, it drives the rack mounting plate 110 to move along the second rack 114. The first cylinder 111 is fixed on the rack mounting plate 110. The first cylinder 111 has a first cylinder rod that extends and retracts along the height direction of the flattening mechanism 100. The flattening plate 112 is installed at the end of the first cylinder rod. The flattening plate 112 flattens the stacked steel bars back and forth into a single layer.

[0059] In some embodiments, the rubbing plate 112 includes a rubbing portion and a connecting portion that are perpendicular to each other. The thickness direction of the rubbing portion is consistent with the axial direction of the reinforcing bar. The rubbing portion is located in the middle of one side of the connecting portion, and the other side of the connecting portion is connected to the end of the first cylinder rod. Since air is compressible, the rubbing plate 112 can act as a buffer when installed at the end of the first cylinder rod to prevent excessive instantaneous resistance during downward rubbing, which could cause the servo motor to alarm.

[0060] In the above embodiment, the thickness direction of the rubbing plate 112 is consistent with the axial direction of the reinforcing bar. Because the reinforcing bar has ribs, if the rubbing plate 112 is in close contact with the surface of the reinforcing bar, it is easy to cause scraping when positioning and pushing the reinforcing bar. To prevent the reinforcing bar from stacking again after rubbing, the rubbing plate 112 maintains a preset distance from the upper surface of the reinforcing bar after rubbing it, so as to prevent the reinforcing bar from stacking again and to expose the reinforcing bar located at the clamping position on the receiving mechanism. Preferably, the preset distance does not exceed half the diameter of the reinforcing bar, generally 2 to 3 mm, so as to effectively prevent the reinforcing bar from stacking again when the reinforcing bar positioning mechanism is activated, and also to prevent the second reinforcing bar from being moved when the first reinforcing bar is clamped.

[0061] In the above embodiments, the up-down and left-right movements of the rolling plate 112 are all servo controlled by the first servo motor-reducer combination 101 and the second servo motor-reducer combination 102, thereby meeting the needs of steel bars of different specifications and sizes.

[0062] To improve the connection stability and smooth movement of the movable plate 108, in some embodiments, there are two guide rails arranged in parallel, such as... Figure 2 The first guide rail 106 is located near the first rack 105 and the second guide rail 107 is located at the end of the movable plate 108.

[0063] Using the aforementioned leveling mechanism, the leveling action is as follows: After the first cylinder 111 is ventilated, the cylinder rod drives the leveling plate 112 to extend downwards. The second servo motor-reducer combination 102 drives the first gear 104 to rotate, causing the components mounted on the movable plate 108 to slide downwards along the guide rail, thereby making the leveling plate 112 contact the surface of the reinforcing bar and apply a certain pressure. At the same time, the rotation of the first servo motor-reducer combination 101 drives the second gear 113 to rotate, driving the rack mounting plate 110 to move the first cylinder 111 and the leveling plate 112 to the designated position. When leveling begins, the servo motor of the first servo motor-reducer combination 101 rotates forward and backward, causing the leveling plate 112 to reciprocate, thereby subjecting the stacked reinforcing bars to both downward pressure and reciprocating lateral compression, ultimately forming a single-layer arrangement of the reinforcing bars.

[0064] After the steel bars are picked up, they are quickly placed on the receiving rod of the receiving mechanism. The flattening mechanism in the above embodiment of the present invention flattens the steel bars stacked on the receiving mechanism into a single layer, eliminating the need for the magnet of the picking mechanism to pick up the steel bars multiple times, which can effectively improve production efficiency.

[0065] Reference Figures 3-6Another embodiment of the present invention provides a rebar picking device, including a support mechanism 700, a receiving mechanism 600, a clamping mechanism 500, a positioning mechanism 200, and a flattening mechanism 100 as described in the above embodiment, wherein: the support mechanism 700 provides support for the entire device, and the support mechanism 700 has a cuboid structure formed by multiple connecting rods; the receiving mechanism 600 is located at the bottom of the support mechanism 700, and includes a receiving rod 602, which is used to place the rebar 300 picked up by the picking mechanism, and the receiving rod 602 is perpendicular to the rebar 300; one end of the receiving rod 602 is a clamping position; the clamping mechanism 500 is fixed on the support mechanism 700 and located above the receiving mechanism 600, and the clamping mechanism 500 clamps the rebar 300 located at the clamping position on the receiving rod 602. And conveyed to the next process; the flattening mechanism 100 is fixed on the support mechanism 700. Specifically, the support 103 of the flattening mechanism 100 is fixed on the support mechanism 700 by means of threaded connection. The flattening mechanism 100 is located on one side of the receiving mechanism 600. The flattening mechanism 100 is away from the clamping position. The flattening mechanism 100 flattens the stacked steel bars 300 on the receiving rod 602 back and forth into a single layer arrangement; the positioning mechanism 200 is fixed on the support mechanism 700. The positioning mechanism 200 is located on one side of the receiving mechanism 600. The positioning mechanism 200 is away from the clamping position. The positioning mechanism 200 pushes the flattened steel bars 300 towards the clamping position along the axial direction of the receiving rod 602, so that the steel bars 300 are arranged closely in sequence from the clamping position. The steel bars 300 from the clamping position include the first steel bar, the second steel bar, etc. in sequence.

[0066] In this embodiment of the invention, after the steel bars are picked up, they are quickly placed on the receiving rod 602 of the receiving mechanism 600. The flattening mechanism 100 flattens the stacked steel bars 300 on the receiving mechanism 600 into a single layer. On the one hand, the magnet of the picking mechanism does not need to pick up the steel bars multiple times, which can effectively improve production efficiency. On the other hand, the magnet does not need to be energized for a long time, which can also effectively prevent safety accidents caused by the sudden drop of steel bars due to the electromagnet losing power during a sudden power outage, thereby improving the safety of steel bar processing. The positioning mechanism 200 positions the flattened steel bars 300, so that the steel bars 300 are arranged closely in sequence from the clamping position, so that the steel bars 300 are clamped in the same position every time. This reduces the requirements of the clamping mechanism 500 and does not require additional sensors or vision systems. It has the advantages of simple structure, low cost and high efficiency. The whole process can be unmanned, which is conducive to improving the automation level of the device feeding.

[0067] Reference Figure 8In some embodiments, the receiving mechanism 600 further includes a third cylinder 603 and a roller 604. The end of the third cylinder rod of the third cylinder 603 is connected to the middle of the receiving rod 602, and the extension and retraction direction of the third cylinder rod is perpendicular to the axial direction of the receiving rod 602. The roller 604 is sleeved on both ends of the receiving rod 602, thereby enabling the receiving rod 602 to move stably and smoothly.

[0068] When the magnet of the picking mechanism picks up the steel bar and lifts it to a certain height, the third cylinder 603 of the receiving mechanism 600 is activated, the receiving rod 602 extends, and the steel bar 300 falls on the receiving rod 602. At this time, the steel bar 300 may be stacked. The above-mentioned flattening mechanism is used to flatten it, so that the steel bar can be arranged in a single layer.

[0069] Reference Figure 7 In some embodiments, the positioning mechanism 200 includes a fixed base 204, a second cylinder 203, a fourth guide rail 205, a positioning push plate 201, and a first positioning post 601. The fixed base 204 is fixed to the support mechanism 700. Preferably, the fixed base 204 is fixed to the support mechanism 700 by welding, and the fixed base 204 is located in front of the receiving mechanism 600. The second cylinder 203 is fixed to the fixed base 204 by a cylinder fixing plate 202. The second cylinder 203 is located above the fixed base 204, and the second cylinder 203 has a direction perpendicular to the reinforcing bar. The second cylinder rod of the rebar 300 has an axial extension and retraction; the fourth guide rail 205 is located on the lower surface of the fixed base 204, and the length direction of the fourth guide rail 205 is consistent with the extension and retraction direction of the second cylinder rod; one end of the positioning push plate 201 is fixed to the slider of the fourth guide rail 205, and the other end is fixed to the end of the second cylinder rod, and the thickness direction of the positioning push plate 201 is perpendicular to the axial direction of the rebar 300; the first positioning post 601 is located on the receiving rod 602 near the clamping position, and the positioning push plate 201 pushes the flattened rebar 300 toward the clamping position to press the first positioning post 601. The flattening plate 112 of the flattening mechanism 100 is located between the first positioning post 601 and the jaws of the clamping mechanism 500.

[0070] In some embodiments, a second positioning post is provided at the end of the receiving rod 602 away from the clamping position. The second positioning post limits the rebar released onto the receiving rod 602, thereby preventing the rebar from falling out of the receiving rod range when the rebar is picked up by the picking mechanism.

[0071] In some embodiments, the receiving mechanism 600 is equipped with a detection switch 400. The detection switch 400 is triggered by the steel bar 300 contacting the first positioning post 601. After the detection switch 400 is triggered, the positioning push plate 201 retracts away from the first positioning post 601.

[0072] The rebar picking device in this embodiment of the invention also includes a control mechanism. When the detection switch 400 fails to detect the rebar 300, the control mechanism controls the picking mechanism to perform the next feeding operation.

[0073] In the above embodiment, the detection switch 400 detects whether there is a steel bar at the clamping position, eliminating the need for additional sensors or vision systems, thereby simplifying the device structure and reducing costs.

[0074] After the flattening is completed, the rebar needs to be positioned. At this time, the second cylinder 203 is activated, driving the positioning push plate 201 to slide along the fourth guide rail 205, squeezing the rebar 300 towards the first positioning post 601. Because the flattening plate 112 is above the rebar 300, the squeezing will not cause secondary stacking. When the rebar 300 approaches the first positioning post 601, the detection switch 400 is triggered, and the positioning push plate 201 retracts. At this time, the clamping mechanism 500 clamps the first rebar and conveys it to the cutting mechanism. After clamping is completed, the positioning mechanism 200 is activated again to push the remaining rebar 300 towards the first positioning post 601. When the detection switch 400 no longer detects the rebar, it means that all the rebars 300 on the receiving rod 602 have been clamped, and the magnet of the picking mechanism needs to be used for the next feeding. Preferably, the second cylinder 203 is equipped with a magnetic switch. When the second cylinder 203 drives the positioning push plate 201 to push the last steel bar on the receiving rod, the magnetic switch is triggered. This enables the feeding action and the clamping action of the last steel bar to be synchronized, which can effectively reduce time waste and improve the steel bar processing efficiency.

[0075] In the above embodiments, the clamping mechanism 500 clamps the reinforcing bars using a gripper gripping method, and its specific implementation can adopt existing technology.

[0076] During the steel bar processing, the initial state of the steel bar being removed from the magnet of the picking mechanism and falling onto the receiving rod 602 of the receiving mechanism 600 is as follows: Figure 9 As shown, using the rebar picking device in the above embodiment of the present invention, when the rebar 300 is removed from the magnet and falls onto the receiving rod 602, resulting in a stack, the flattening mechanism 100 is used to repeatedly flatten the stacked rebar 300 into a single layer, as shown. Figure 10 As shown; the smoothing mechanism 100 detaches from the surface of the reinforcing bar 300 and lifts it to a certain height, and moves horizontally to expose the first reinforcing bar 300. Then, the positioning mechanism 200 pushes the reinforcing bar 300 to one side of the clamping position to eliminate the gap between the reinforcing bars. After that, the positioning mechanism 200 retracts, and the clamping mechanism 500 clamps the first reinforcing bar. Figure 11As shown. When clamping the second rebar, the positioning mechanism 200 only needs to move to push the rebar 300 to eliminate the gap between the rebars. At this time, the second rebar is located at the position of the first rebar that has been clamped (i.e., the clamping position), which facilitates the next clamping. No additional sensors or visual detection of the rebar's position are needed for the second clamping. Except for the first flattening action, the entire flattening mechanism 100 does not move. The flattening plate 112 is located on the upper surface of the rebar 300, which can effectively prevent secondary stacking caused by the operation of the positioning mechanism 200, and also prevent the second rebar from being moved when the first rebar is clamped. This method has a simple structure, high efficiency, and low cost.

[0077] The flattening mechanism and rebar picking device provided in the above embodiments of the present invention allow for the rapid placement of picked-up rebars onto the receiving rod of the receiving mechanism. The flattening mechanism flattens the stacked rebars on the receiving mechanism into a single layer, eliminating the need for rebar stacking and multiple magnetic extractions, thus effectively improving production efficiency and enabling unmanned operation. The positioning mechanism positions the flattened rebars, ensuring that the rebars are tightly arranged in sequence at the clamping positions, guaranteeing that the rebars are always clamped in the same location. This reduces the requirements for the clamping mechanism, eliminating the need for additional sensors or vision systems, thereby simplifying the device structure and reducing costs.

It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
