Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and in particular to a steel bar feeding device. Background Technology

[0002] In steel bar processing production lines, steel bars are typically manually picked up and fed onto processing equipment for shearing, rolling, and other processing. To facilitate operator access, the processing equipment is usually located next to the steel bar conveyor rollers. Once the steel bars are conveyed to the designated position on the processing equipment, the conveyor stops, and the operators manually place them onto the shearing machine, rolling mill, or other processing equipment for further processing. This loading process is labor-intensive and time-consuming. Alternatively, robots can be used to assist in transferring the steel bars from the conveyor rollers to the processing equipment; however, robots typically can only load one bar at a time, resulting in low loading efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a steel bar feeding device to solve the problem of low steel bar feeding efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A rebar feeding device includes a frame, a gripping mechanism, a feeding mechanism, a counting mechanism, and a distributing mechanism. The gripping mechanism is mounted on the frame via a fixed plate and includes a gripping drive and a gripping head. The gripping drive drives the gripping head to move up and down, and the gripping head can grip multiple rebars simultaneously. The feeding mechanism is mounted on the frame and includes a feeding roller, a feeding drive, and a clearance drive. The feeding roller supports the rebar gripped by the gripping mechanism and has a threaded groove on its outer periphery. The feeding drive is connected to the feeding roller and drives the feeding roller to rotate around its own axis, so that the rebar moves from a first end of the feeding roller to a second end of the feeding roller. The clearance drive is connected to the feeding mechanism. The feeding roller is used to drive the feeding roller to rotate about a first hinge axis extending along a second direction, so that the feeding roller switches between a feeding position and a first clearance position. When in the feeding position, the feeding roller extends along a horizontally arranged first direction. When in the first clearance position, the feeding roller is arranged at an angle to the horizontal plane. The counting mechanism is disposed on the frame and located above the feeding roller when it is in the feeding position. The distributing mechanism is disposed on the frame and located on the side of the counting mechanism near the second end of the feeding roller. The distributing mechanism includes a distributing drive and a distributing head. The distributing drive is connected to the distributing head and is used to remove excess steel bars from the feeding roller. The second direction is perpendicular to the first direction.

[0006] In one embodiment, the feeding head includes a magnet, and the rebar feeding device further includes a discharging mechanism. The discharging mechanism includes a first discharging component and a second discharging component respectively disposed on opposite sides of the magnet. The first discharging component and the second discharging component are used to limit the rebar from rising with the magnet.

[0007] In one embodiment, the first unloading assembly includes an unloading rod, an unloading block, and a buffer. The unloading rod is flexibly connected to the material gripping mechanism through the buffer, and the unloading block is disposed at the bottom of the unloading rod.

[0008] In one embodiment, the second unloading assembly includes an unloading roller rotatably mounted on the fixed plate and extending along the first direction.

[0009] In one embodiment, the material gripping mechanism further includes a magnetic base and a hinge base, the hinge base being disposed at the output end of the material gripping drive, and the magnetic base being hinged to the hinge base via a first hinge shaft extending along the first direction.

[0010] In one embodiment, the material gripping mechanism further includes a flipping drive, the fixed plate is hinged to the frame via a second hinge shaft extending along the second direction, and the flipping drive is hinged to the frame and the fixed plate.

[0011] In one embodiment, the pitch of the threaded groove gradually increases from the first end of the feed roller to the second end of the feed roller.

[0012] In one embodiment, the counting mechanism includes a photoelectric sensor whose vertical orthographic projection is offset from the feed roller.

[0013] In one embodiment, the counting mechanism includes an adjustment drive for driving the photoelectric sensor to move up and down.

[0014] In one embodiment, the rebar feeding device further includes a material blocking mechanism, which includes a material blocking rod and a material blocking drive. The material blocking drive is mounted on the frame and connected to the material blocking rod to drive the material blocking rod to rotate. The material blocking rod is configured as an inverted L-shape to prevent the rebar from falling back to its initial position when it is pushed off.

[0015] The beneficial effects of this utility model are as follows: The steel bar feeding device proposed in this utility model uses a grabbing mechanism to grab multiple steel bars onto the feeding roller at the same time, which can realize the simultaneous feeding of multiple steel bars. Moreover, the steel bar feeding device includes a counting mechanism and a distributing mechanism, which can accurately control the number of steel bars fed, and is conducive to the use in conjunction with the processing equipment of the next process.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] An embodiment of this utility model proposes a steel bar feeding device for transferring bar materials, including but not limited to steel bars, from one device to another.

[0035] refer to Figures 1-5As shown, the rebar feeding device of this utility model includes a frame 6, a gripping mechanism 1, a feeding mechanism 2, a distributing mechanism 4, and a counting mechanism 8. The gripping mechanism 1, the feeding mechanism 2, the distributing mechanism 4, and the counting mechanism 8 are all mounted on the frame 6. The gripping mechanism 1 is used to grip rebars. The gripping mechanism 1 includes a gripping drive component 11 and a gripping head 12. The gripping drive component 11 is used to drive the gripping head 12 to rise and fall. The gripping head 12 can grip multiple rebars simultaneously. The feeding mechanism 2 includes a feeding roller 21, a feeding drive 22, and a clearance drive 23. The feeding roller 21 supports the reinforcing bars gripped by the gripping head 12. The outer circumference of the feeding roller 21 is provided with threaded grooves. The feeding drive 22 is connected to the feeding roller 21 and drives the feeding roller 21 to rotate around its own axis, so that the reinforcing bars move along the axial direction of the feeding roller 21 from the first end to the second end under the guidance of the threaded grooves. The clearance drive 23 is also connected to the feeding roller 21 and drives the feeding roller 21 to rotate up and down, switching the feeding roller 21 between a feeding position and a first clearance position. When the feeding roller 21 is in the feeding position, it moves along a horizontally positioned first direction (…). Figure 1 Extending in the X direction, when the feed roller 21 is in the first avoidance position, it is set at an angle to the horizontal plane to avoid interference with the gripping mechanism 1, thereby moving the reinforcing bars located below the feed roller 21 to above the feed roller 21. The counting mechanism 8 is set above the feed roller 21 in the feeding position and is used to count the number of reinforcing bars moved into the next process. The material distribution mechanism 4 is used to remove excess reinforcing bars on the feed roller 21. The material distribution mechanism 4 is set on the side of the counting mechanism 8 close to the first end of the feed roller 21 in the first direction. The material distribution mechanism 4 includes a material distribution head 41 and a material distribution drive 42. The material distribution drive 42 is used to drive the material distribution head 41 to rise and fall. It is understandable that the excess steel bars on the feed roller 21 refer to the remaining steel bars on the feed roller 21 after the number of steel bars measured by the counting mechanism 8 meets the preset feeding requirements. For example, if there are 4 steel bars on the feed roller 21 and the preset feeding requirement is 2 steel bars, then after the counting mechanism 8 measures 2 steel bars at a time and moves them to the second end of the feed roller 21 and enters the next process, the remaining 2 steel bars on the feed roller 21 will be removed by the material distribution mechanism 4.

[0036] The aforementioned rebar feeding device utilizes a gripping head 12 capable of simultaneously gripping multiple rebars. The rebars are then transferred to a feeding roller 21. As the feeding roller 21 rotates, the rebars move sequentially from the first end to the second end of the feeding roller 21 along a first direction, thus entering the processing equipment for the next process. During this movement, a counting mechanism 8 counts the passing rebars. After meeting the preset feeding requirements, the remaining rebars fall from the feeding roller 21, which has switched from its feeding position to a first clearance position, under the action of a separating mechanism 4. This achieves simultaneous feeding of multiple rebars, resulting in high feeding efficiency and the ability to count the number of rebars fed, which is beneficial for integration with the processing equipment for the next process. For example, the equipment preceding the rebar feeding device is a rebar feeding trolley or conveyor roller conveyor, while the equipment following the rebar feeding device is a shearing machine or rolling mill, etc. The processing equipment has support rollers extending along the first direction, which can support the rebars conveyed by the feeding roller 21.

[0037] refer to Figure 2 and Figure 3 As shown, in one embodiment, the gripping head 12 includes a magnet 121. The magnet 121 can quickly attract reinforcing bars (reinforcing bars are mainly composed of iron and are ferromagnetic materials, thus they can be attracted by magnets), and can improve the stability of the reinforcing bars during the conveying process. It is especially suitable for smooth or damp reinforcing bars, with a low risk of falling. Compared with mechanical grippers, it reduces maintenance requirements and can adapt to the feeding of reinforcing bars of different diameters. It is worth emphasizing that the magnet 121 is a permanent magnet, which provides higher stability when gripping reinforcing bars compared to electromagnets.

[0038] Specifically, the gripping head 12 also includes a magnetic base 122, wherein the magnetic base 122 is U-shaped with the opening facing downward, and the magnet 121 is embedded in the magnetic base 122 and connected to the gripping drive component 11 through the magnetic base 122.

[0039] More specifically, in order to extend the service life of the magnet 121, a hinge seat is provided at the output end of the gripping drive component 11, and the magnetic suction seat 122 is hinged to the gripping drive component 11 through a first hinge shaft 17 passing through the hinge seat. When gripping the steel bar, the magnetic suction seat 122 can swing relative to the gripping drive component 11, reducing the possibility of hard contact between the magnet 121 and the steel bar, and extending the service life of the magnet.

[0040] Continue to refer to Figure 2 and Figure 3As shown, the material gripping drive 11 uses a cylinder. To improve the lifting stability of the material gripping head 12, the material gripping mechanism 1 also includes a guide sleeve 15, a guide rod 19, and a fixing plate 13. The cylinder and the guide sleeve 15 are both mounted on the fixing plate 13 and connected to the frame 6 through the fixing plate 13. The guide rod 19 moves vertically through the guide sleeve 15 and is fixedly connected to the output end of the material gripping drive 11. The vertical direction is the third direction, that is... Figure 1 The Z-direction is perpendicular to the X-direction. When the gripping drive 11 extends or retracts, the guide rod 19 moves up and down under the guidance of the guide sleeve 15, thereby realizing the lifting and lowering of the gripping head 12.

[0041] In one embodiment, reference Figure 3 and Figure 4 As shown, the material handling mechanism 1 also includes a tilting drive 14, and the fixed plate 13 is driven along the second direction ( Figure 1 A second hinge shaft 18 extending in the Y direction is hinged to the frame 6. One end of the flipping drive 14 is hinged to the frame 6, and the other end is hinged to the fixed plate 13, driving the fixed plate 13 to rotate the material gripping drive 11 and the material gripping head 12 around the second hinge shaft 18. This allows the fixed plate 13 to switch between a dropping position and a second avoidance position. When in the dropping position, the material gripping drive 11 moves vertically. When in the second avoidance position, the material gripping drive 11 moves horizontally, with the second direction being a horizontal direction perpendicular to the first direction. The flipping drive 14 avoids the feed roller 21 in the first avoidance position, allowing the reinforcing bar to move above the feed roller 21. The lifting and lowering of the material gripping head 12 is synchronized with the switching of the feed roller from the first avoidance position to the feeding position, further improving the feeding efficiency.

[0042] Initially, the feed roller 21 is in the first clearance position. The gripping head 12 rises under the action of the gripping drive 11 and flips away from the feed roller 21 under the action of the flipping drive 14. At the same time, the feed roller 21 switches from the first clearance position to the feeding position. The gripping head 12 flips towards the feed roller 21 under the action of the flipping drive 14 and continues to rise. Under the action of the unloading mechanism 3, the steel bar falls onto the feed roller 21 in the feeding position. Specifically, the flipping drive 14 is also a cylinder.

[0043] Based on the premise that the gripping head 12 includes a magnet 121, the rebar feeding device also includes a discharge mechanism 3, which is used to disengage the rebar from the magnet 121. Specifically, the discharge mechanism 3 includes a first discharge component 31 and a second discharge component 32, which are respectively disposed on opposite sides of the gripping mechanism 1 in a direction perpendicular to the first direction. When the gripping drive 11 drives the gripping head 12 upward, the rebar on the gripping head 12 can abut against the first discharge component 31 and the second discharge component 32. Under the restriction of the first discharge component 31 and the second discharge component 32, the rebar cannot rise with the gripping drive 11, and the rebar falls onto the feeding roller 21 in the feeding position.

[0044] refer to Figure 2 As shown, the first unloading assembly 31 includes an unloading rod 311 and an unloading block 312. The unloading block 312 is disposed at the bottom of the unloading rod 311. The unloading rod 311 includes an unloading section and a guide section. The guide section moves in the same direction as the gripping drive 11. The unloading section and the guide section are connected by a connecting section. The connecting section is set at an angle to both the unloading section and the guide section. In order to reduce the possibility of local shaking of the unloading rod 311, the first unloading assembly 31 also includes a support member 314. One end of the support member 314 is connected to the guide section, and the other end extends through the mounting plate for mounting the gripping head 12 at the output end of the gripping drive 11 and is connected to the connecting section.

[0045] Specifically, the first unloading assembly 31 also includes a buffer 313, which is connected to the guide section and the fixing plate 13, allowing the first unloading assembly 31 to be flexibly connected to the gripping mechanism 1. This buffer acts as a cushion when the unloading block 312 abuts against the reinforcing bar, preventing damage to the unloading block 312 or the reinforcing bar. For example, the buffer 313 is a cylinder. Obviously, the buffer 313 can also be replaced by an elastic element such as a spring, which will not be elaborated further here.

[0046] More specifically, in order to restrict the movement of the unloading rod 311 relative to the gripping head 12, a strip-shaped guide hole is provided on the mounting plate, and the support member 314 is movably inserted into the guide hole. The side walls of the guide hole on both sides restrict the lifting distance of the unloading rod 311.

[0047] refer to Figure 3 As shown, the second unloading assembly 32 includes an unloading roller 321 and a roller connecting plate 322. The roller connecting plate 322 is connected to the bottom of the fixed plate 13, and the unloading roller 321 is rotatably mounted on the roller connecting plate 322. It is worth emphasizing that when the fixed plate 13 is in the dropping position, the unloading roller 321 is parallel to the feeding roller 21, so as to synchronously push the steel bar on the magnet 121 onto the feeding roller 21.

[0048] Specifically, to accommodate the first unloading assembly 31, the height of the roller connecting plate 322 on the fixed plate 13 is adjustable. For example, one of the roller connecting plate 322 and the fixed plate 13 has a vertically extending strip-shaped first mounting hole, and the other has a circular second mounting hole. The roller connecting plate 322 and the fixed plate 13 are connected by fasteners passing through the first and second mounting holes. By adjusting the position of the fasteners in the first mounting hole, the height of the roller connecting plate 322 can be adjusted, thereby adjusting the height of the unloading roller 321. Obviously, in the initial state, the height of the unloading roller 321 is higher than the height of the unloading block 312.

[0049] To improve the service life of the first unloading assembly 31 and the second unloading assembly 32, the unloading roller 321, the unloading rod 311, and the unloading block 312 are made of steel. Furthermore, to prevent the magnet 121 from adhering to the unloading block 312, the gripping mechanism 1 also includes a limiting bolt 16. The limiting bolt 16 is located on the side of the hinge seat near the unloading roller 321 to limit the swing angle of the magnetic seat 122. It should be emphasized that since the first unloading assembly 31 is flexibly connected to the gripping mechanism 1, and the horizontal distance between the first unloading assembly 31 and the magnet 121 is relatively large, the limiting bolt 16 does not need to be provided on the other side of the hinge seat.

[0050] refer to Figure 4 and Figure 5 As shown, the threaded groove on the feed roller 21 has a gradually increasing pitch from the first end to the second end. The pitch at the first end of the feed roller 21 is relatively small, which can restrict more steel bars on the feed roller 21. The pitch at the second end of the feed roller 21 is relatively large, which can speed up the transmission efficiency of the steel bars and allow the steel bars to enter the next process more quickly, further improving the feeding efficiency.

[0051] In one embodiment, the feeding drive 22 is a motor, while the avoidance drive 23 is a cylinder. One end of the avoidance drive 23 is hinged to the frame 6, and the other end is hinged to the fixed end of the feeding drive 22. The feeding drive 22 is hinged to the frame 6 via a third hinge shaft 24 extending in a second direction.

[0052] Continue to refer to Figure 2 and Figure 4 As shown, the counting mechanism 8 includes a detection connector 81, which is located above the feed roller 21 in the feeding position. A photoelectric sensor 82 is mounted on the detection connector 81. The photoelectric sensor 82 is used to detect the number of steel bars that pass through the photoelectric sensor 82 sequentially. Specifically, to avoid the feed roller 21 affecting the counting accuracy, the orthographic projection of the photoelectric sensor 82 in the vertical direction is offset from that of the unloading roller 321, that is, the photoelectric sensor 82 is located obliquely above the feed roller 21 in the feeding position.

[0053] In one embodiment, to accommodate steel bars of different diameters, the height of the detection joint 81 and the photoelectric sensor 82 disposed on the detection joint 81 are adjustable. Specifically, the counting mechanism 8 also includes an adjustment drive 83, which is used to drive the detection joint 81 and the photoelectric sensor 82 on the detection joint 81 to rise and fall, so as to adjust the vertical distance between the photoelectric sensor 82 on the detection joint 81 and the feed roller 21.

[0054] To improve adjustment accuracy, the adjustment drive 83 employs an electric reducer. The counting mechanism 8 also includes a detection shaft 84 and a limiting sleeve 85. The limiting sleeve 85 is fixed to the frame 6. The detection shaft 84 is threadedly connected to the output end of the adjustment drive 83 and passes vertically within the limiting sleeve 85, slidingly connected to it. The limiting sleeve 85 has a strip-shaped limiting hole extending vertically. The detection shaft 84 has a limiting pin 86 that slides within the limiting hole, restricting the detection shaft 84 from rotating with the limiting sleeve 85. Therefore, when the adjustment drive 83 rotates, the detection shaft 84, circumferentially limited by the limiting sleeve 85, can only move vertically. For example, the limiting pin 86 is an elastic cylindrical cotter pin.

[0055] In addition, the counting mechanism 8 also includes an encoder and a proximity sensor 87. The encoder is fixed to the motor reducer and connected to the detection shaft 84 via a coupling. The proximity sensor 87 is used to detect the position of the limit pin 86 to determine the height of the detection joint 81.

[0056] More specifically, the electric reducer uses a three-phase asynchronous motor and encoder to form a closed-loop control, which can accurately provide feedback on the position of the detection connector 81. The overall adjustment is simple, convenient and low in cost.

[0057] refer to Figure 5 As shown, the material separating head 41 includes a first plane and a second plane arranged at an angle. The intersection line of the first plane and the second plane is inclined downward from one end away from the feed roller 21 to the other end, so as to better insert between two adjacent steel bars, thereby removing excess steel bars. Specifically, in order to improve the movement stability of the material separating head 41, the material separating drive component 42 adopts a double-rod cylinder.

[0058] In one embodiment, the rebar feeding device further includes a retaining mechanism 5, which is located on the side of the distributing head 41 away from the feeding roller 21. The retaining mechanism 5 is used to return the rebar to the rebar feeding trolley when it is pushed off by the distributing head 41, that is, back to the initial position where the rebar was taken out by the grabbing mechanism 1. (Reference) Figure 5As shown, the material blocking mechanism 5 includes a material blocking rod 53 and a material blocking drive 51. The material blocking drive 51 is mounted on the frame 6 and is used to drive the material blocking rod 53 to flip. The material blocking rod 53 is configured as an inverted L-shape, which can flip to the first end close to the feed roller 21 under the drive of the material blocking drive 51 to prevent the steel bar from moving in the direction away from the second end of the feed roller 21.

[0059] Specifically, the material blocking drive 51 is a cylinder, and the material blocking mechanism 5 also includes a material blocking arm 52. One end of the material blocking drive 51 is hinged to the frame 6, and the other end is hinged to the material blocking arm 52. The end of the material blocking arm 52 away from the material blocking drive 51 is hinged to the frame 6. The first end of the material blocking rod 53 is connected to the material blocking arm 52 so as to rotate when the material blocking arm 52 rotates. When the material blocking drive 51 extends, the second end of the material blocking rod 53 is inclined from top to bottom toward the second end of the feed roller 21.

[0060] refer to Figure 1 and Figure 2 As shown, the rebar feeding device also includes a rotating mechanism 7, which includes a rotating arm 71, a support base 73, and a rotating drive component 72. One end of the rotating arm 71 is hinged to the support base 73 via a vertically arranged fourth hinge shaft, and the other end is connected to the frame 6. The rotating drive component 72 is used to drive the rotating arm 71 to rotate around the fourth hinge shaft. When there is no raw material in the rebar feeding trolley, the rebar feeding device can avoid the rebar feeding trolley, facilitating batch replenishment of the rebar feeding trolley.

[0061] In one embodiment, in order to realize the automatic control of the rebar feeding device, the rebar feeding device also includes a controller, which is communicatively connected to the grabbing mechanism 1, the feeding mechanism 2, the separating mechanism 4, the blocking mechanism 5 and the unloading mechanism 3.

[0062] The following is a brief description of the specific operation process of the above-mentioned steel bar feeding device.

[0063] When there is a need for feeding steel bars, the rotating drive 72 drives the rotating arm 71 to rotate to 90 degrees and reach the top of the steel bar feeding trolley. The gripping drive 11 drives the magnet 121 to descend, and the magnet 121 is attached to and attracted to the steel bar. During the retraction of the gripping drive 11, the flipping drive 14 drives the fixing plate 13 to rotate, and the avoidance drive 23 extends, causing the feeding drive 22 and the feeding roller 21 to flip up and hit the steel bar that has just been attracted. The gripping drive 11 continues to retract, and under the blocking action of the unloading block 312 and the unloading roller 321, the steel bar falls onto the feeding roller 21. The surface of the feed roller 21 is designed with a spiral shape. When the photoelectric sensor 82 detects the number of steel bars when feeding them into the processing equipment, the material distribution drive 42 extends and drives the material distribution head 41 to descend. This works in conjunction with the feed roller 21 moving to the first clearance position to push down the excess steel bars on the feed roller 21, thus completing the feeding process. The material blocking drive 51 extends before the material distribution drive 42 extends to prevent the steel bars from becoming tangled when the material distribution head 41 pushes down the excess steel bars on the feed roller 21, so that the excess steel bars return to the steel bar feeding trolley.

[0064] It is worth emphasizing that before the equipment is put into operation, the positions of the proximity sensor 87 and the limit pin 86 need to be adjusted according to the diameter of the steel bars required by the processing equipment, so as to adjust the distance of the photoelectric sensor 82 relative to the feed roller 21. The adjustment is achieved by adjusting the drive component 83 to drive the detection shaft 84 to rise and fall.

[0065] Furthermore, in order to precisely limit the stroke of any of the aforementioned cylinder-based drive components (including gripping drive components, avoidance drive components, feeding drive components, flipping drive components, and blocking drive components), the moving end of the cylinder is magnetic and can cooperate with a magnetic switch. For example, the gripping drive component 11 is equipped with a first magnetic switch, a second magnetic switch, and a third magnetic switch corresponding to its output end retracted position, extended position, and a certain position during the extension process. The first magnetic switch is used to control the gripping drive component 11 to stop retracting, the second magnetic switch is used to control the gripping drive component 11 to stop extending, and the third magnetic switch is used to transmit information to the avoidance drive component 23. When the gripping drive component 11 moves to the aforementioned certain position, the avoidance drive component 23 is activated, causing the feeding roller 21 to flip up and down.
