Description

Technical Field

[0001] This application relates to the technical field of bar production and processing, and in particular to an automated bar feeding device. Background Technology

[0002] Bar stock is a cylindrical long strip material, made of materials such as low alloy steel, titanium alloy, and nickel-based alloy. It can be produced by stretching, die extrusion, machining or precision shearing, and is often used in forging manufacturing. Bar stock is widely used in many fields such as construction, machinery manufacturing, automobiles, and power.

[0003] When processing bar stock, the first step is to cut the long bar stock into short bars of the required length. The worker puts the long bar stock into the cutting area of ​​the cutting equipment. The cutting equipment uses a robotic arm to hold and push the bar stock to the cutting tool of the cutting equipment for cutting periodically.

[0004] Regarding the aforementioned existing technology, workers must wait until the bar is cut before they can continue feeding materials. During the bar cutting process, workers can only wait on the side and cannot use this time to perform other tasks, which affects their work efficiency. Utility Model Content

[0005] This application proposes an automated bar feeding device, which allows workers to have a longer downtime to perform other tasks after each feeding.

[0006] This application provides an automated bar feeding device, which adopts the following technical solution: An automated bar feeding device includes a frame, on which are mounted a placement rack for holding multiple bars and a feeding mechanism for transferring the bars on the placement rack. The placement rack is inclined and consists of several racks evenly spaced along the length of the frame. Each placement rack has a limiting member to prevent the bars from rolling, and the limiting member corresponds to several placement racks. The feeding mechanism is positioned between two adjacent placement racks, and it lifts the bars from the placement racks and passes them over the limiting members, causing the bars to roll on the limiting members and eventually roll into the cutting area of ​​the cutting equipment.

[0007] By adopting the above technical solution, workers can place multiple bars on the placement rack at once. The system controls the feeding mechanism to lift the bars on the rack. Once the height of the bars exceeds the limiters, they pass over the limiters and roll on them, eventually rolling into the cutting area of ​​the cutting equipment. The inclined design of the placement rack allows the bars to roll using their own weight, and the limiters prevent multiple bars from rolling down into the cutting area of ​​the equipment. The system periodically controls the feeding mechanism to lift the bars, achieving automated feeding. This allows workers a longer downtime after each feeding to perform other tasks, improving their time utilization.

[0008] Preferably, the feeding mechanism includes a driving component and a lifting component, the lifting component being slidably mounted on the side wall of the placement rack; the driving component is mounted on the rack body, and the driving component drives the lifting component to slide up and down on the side wall of the placement rack; a plurality of lifting components are provided for a plurality of placement racks, and the plurality of lifting components are slidably mounted on the side walls of a plurality of placement racks respectively; the driving component drives the plurality of lifting components to slide on the placement rack.

[0009] By adopting the above technical solution, the lifting component is slidably installed on the side wall of the placement frame and driven up and down by the driving component. The driving component periodically drives the sliding component, causing the bar to periodically roll past the limiting component to the cutting area of ​​the cutting equipment. Since the bar is long, when a single lifting component lifts the bar, the bar may tilt and may not be able to enter the cutting area. Multiple lifting components are used to lift multiple points of the bar to prevent the bar from tilting and ensure that the bar can enter the cutting area. By using a single driving component to drive several lifting components to slide, the complexity of the equipment and manufacturing cost are reduced.

[0010] Preferably, the feeding mechanism further includes a rotating shaft, which is arranged along the length of the frame and passes through several placement frames. The two ends of the rotating shaft are rotatably connected to the placement frames located at both ends of the length of the frame. A feeding block is sleeved on the rotating shaft, and one end of the feeding block is hinged to the driving component. Several groups of feeding blocks are arranged corresponding to several placement frames. Several groups of feeding blocks are all sleeved on the rotating shaft, and several groups of feeding blocks are respectively hinged to several lifting components.

[0011] By adopting the above technical solution, the rotating shaft, as the core linkage component, transmits the power of the driving component to all lifting components synchronously through multiple sets of feeding blocks, ensuring that the movements of multiple lifting components are completely synchronized; through the hinge structure of the rotating shaft and the feeding blocks, the linear motion of the driving component is converted into the sliding motion of the lifting components, thus optimizing the device structure; the rotating shaft passes through multiple placement frames, indirectly strengthening the connection between the placement frames, reducing the shaking of the placement frames caused by force during feeding, and improving the overall stability of the equipment.

[0012] Preferably, pins are fixed on the side wall of the placement frame, and a sliding groove is opened through the middle of the lifting member in the vertical direction. There are two pins, both of which are located in the sliding groove and restrict the highest and lowest positions of the lifting member's sliding. Several sets of two pins are provided for several lifting members.

[0013] By adopting the above technical solution, the two pins respectively limit the lowest and highest sliding positions of the lifting component, ensuring that the lifting range of the lifting component is neither too low to prevent the bar from being lifted, nor too high to prevent the device from doing useless work and reducing work efficiency.

[0014] Preferably, the driving component is a cylinder, and the end of the output shaft of the cylinder is hinged to the loading block.

[0015] By adopting the above technical solution, the cylinder structure is simple and has a low failure rate. Compared with driving components such as motors, it is more suitable for long-term, high-frequency reciprocating motion scenarios, reducing the difficulty and cost of equipment maintenance. When the cylinder output shaft extends, the feeding block moves with the cylinder output shaft, causing the rotating shaft to rotate counterclockwise, which in turn causes the feeding blocks of other groups to rotate. The other end of the feeding block causes the lifting component to slide downward. When the cylinder output shaft retracts, the feeding block moves with the cylinder output shaft, causing the rotating shaft to rotate clockwise, which in turn causes several feeding blocks to rotate. The other end of the feeding block causes the lifting component to slide downward. The lifting component lifts the bar. After the bar is higher than the limit component, it rolls on the limit component. Finally, the bar rolls into the cutting area of ​​the cutting equipment.

[0016] Preferably, the limiting member is a right-angled trapezoidal plate, which is fixed to the side wall of the placement frame away from the lifting member. The right-angled side of the limiting member is perpendicular to the surface of the placement frame used to place the bar. The right-angled side of the limiting member is positioned close to the bar to prevent the bar from rolling.

[0017] By adopting the above technical solution, the right-angled side of the trapezoid is perpendicular to the surface of the placement rack, which can form a rigid barrier. The vertical force can effectively prevent the bar from rolling due to gravity and prevent the bar from slipping off prematurely when it is not loaded. After the bar is lifted over the limiter, it can roll smoothly along the inclined side to ensure that the bar can roll into the cutting area.

[0018] Preferably, the frame is further provided with reinforcing rods, which are arranged along the length of the frame and pass through several placement racks, with both ends of the reinforcing rods fixed to the frame.

[0019] By adopting the above technical solution, the reinforcing rod runs through multiple placement frames, connecting the scattered placement frames into a whole, reducing the shaking of the placement frames caused by vibration and force during feeding or cutting, and further improving the overall stability of the equipment.

[0020] Preferably, the feeding mechanism includes a drive motor, a drive shaft, a driven shaft, and a conveyor belt. The drive shaft and the driven shaft are arranged parallel to each other and are respectively installed through and rotatably on several placement racks along the length of the frame. The drive motor is fixed to one end of the drive shaft and installed on one side wall of the placement rack to drive the drive shaft to rotate. The conveyor belt is respectively wound around the drive shaft and the driven shaft. Several partitions are provided on the conveyor belt. The partitions are arranged perpendicular to the surface of the conveyor belt and are evenly spaced along the length of the conveyor belt. A receiving groove for placing bars is formed between two adjacent partitions. Several conveyor belts are provided corresponding to several placement racks and are respectively located on one side of different placement racks.

[0021] By adopting the above technical solution, this is the second implementation of the feeding mechanism. The operator puts multiple bars into several receiving slots formed between several adjacent partitions. Then the system controls the drive motor to rotate, the drive motor rotates the drive shaft, the drive shaft rotates the conveyor belt and thus moves the bars. The periodic rotation of the drive motor ensures that the next bar is transported to the cutting area after the previous bar is cut by the cutting equipment, realizing automated feeding. This allows the operator to have a longer downtime to perform other tasks after each feeding, improving the operator's time utilization rate.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The operator places multiple bars on the placement rack at once. The system controls the feeding mechanism to lift the bars on the rack. Once the bars are higher than the limiters, they pass over the limiters and roll on them, eventually rolling into the cutting area of ​​the cutting equipment. The inclined placement rack allows the bars to roll using their own weight, and the limiters prevent multiple bars from rolling down into the cutting area of ​​the equipment. The system periodically controls the feeding mechanism to lift the bars, achieving automated feeding. This allows the operator a longer downtime after each feeding to perform other tasks, improving the operator's time utilization. 2. When the cylinder output shaft extends, the feeding block moves with the cylinder output shaft, causing the rotating shaft to rotate counterclockwise, which in turn causes the feeding blocks of other groups to rotate; the other end of the feeding block causes the lifting component to slide downward; when the cylinder output shaft retracts, the feeding block moves with the cylinder output shaft, causing the rotating shaft to rotate clockwise, which in turn causes several feeding blocks to rotate; the other end of the feeding block causes the lifting component to slide downward, the lifting component lifts the bar, and after the bar height is higher than the limit component, it rolls on the limit component, and finally the bar rolls into the cutting area of ​​the cutting equipment; 3. The reinforcing rod runs through multiple placement racks, connecting the scattered placement racks into a whole, reducing the shaking of the placement racks caused by vibration and force during loading or cutting, and further improving the overall stability of the equipment.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0026] This application discloses an automated bar feeding device.

[0027] Example 1: refer to Figure 1 An automated bar feeding device includes a frame 1, a placement rack 2 for placing multiple bars, a limiting member 3 for preventing the bars from rolling, a feeding mechanism 4 for transferring the bars on the placement rack 2, and reinforcing rods 5. The placement rack 2 is inclined and has several placement racks along the length of the frame 1, with the several placement racks 2 evenly spaced. Several limiting members 3 are also provided for the several placement racks 2. The feeding mechanism 4 is installed on the placement rack 2. The reinforcing rods 5 are installed along the length of the frame 1 and pass through several placement racks 2. The two ends of the reinforcing rods 5 are fixed to the two ends of the frame 1 along the length of the frame 1 by bolts and their own threads. The reinforcing rods 5 connect the dispersed placement racks 2 into a whole, reducing the shaking of the placement racks 2 caused by vibration and force during feeding or cutting, and further improving the overall stability of the equipment.

[0028] refer to Figure 1 and Figure 2The feeding mechanism 4 includes a driving component 41, a lifting component 42, a rotating shaft 43, and a feeding block 44. The lifting component 42 is slidably installed on the side wall of the placement rack 2. The driving component 41 is bolted to the frame 1. The driving component 41 drives the lifting component 42 to slide on the side wall of the placement rack 2. There are a number of lifting components 42 corresponding to a number of placement racks 2. The number of lifting components 42 are slidably installed on the side walls of a number of placement racks 2 respectively. In this embodiment, the driving component 41 is a cylinder, there are four placement racks 2, and there are four lifting components 42.

[0029] A rotating shaft 43 is arranged along the length of the frame 1. The rotating shaft 43 passes through several placement racks 2 and its two ends are respectively rotatably connected to the placement racks 2 located at both ends of the length of the frame 1 through bearings. Two pins 6 are welded and fixed on the side wall of the placement rack 2. A sliding groove 7 is opened through the lifting member 42. The sliding groove 7 is arranged in the vertical direction. Both pins 6 are located inside the sliding groove 7. Several sets of two pins 6 are arranged for several lifting members 42. In this embodiment, four sets of two pins 6 are arranged.

[0030] The two pins 6 respectively limit the lowest and highest sliding positions of the lifting component 42, ensuring that the lifting range of the lifting component 42 is neither too low to prevent it from lifting the bar, nor too high to prevent the device from doing useless work and reducing work efficiency.

[0031] The feeding block 44 is sleeved on the rotating shaft 43 and is snapped and fixed to the rotating shaft 43. One end of the feeding block 44 is hinged to the output shaft of the driving member 41, and the other end of the feeding block 44 is hinged to the end of the lifting member 42 away from the pin 6. In this embodiment, the feeding blocks 44 are sleeved on the rotating shaft 43 in groups of two. There are four groups of feeding blocks 44. All four groups of feeding blocks 44 are sleeved on the rotating shaft 43. The four groups of feeding blocks 44 are respectively hinged to the four lifting members 42.

[0032] When the cylinder output shaft extends, the feeding block 44 moves with the cylinder output shaft, causing the rotating shaft 43 to rotate counterclockwise, which in turn causes the feeding blocks 44 of other groups to rotate; the other end of the feeding block 44 causes the lifting member 42 to slide downward; when the cylinder output shaft retracts, the feeding block 44 moves with the cylinder output shaft, causing the rotating shaft 43 to rotate clockwise, which in turn causes several feeding blocks 44 to rotate; the other end of the feeding block 44 causes the lifting member 42 to slide downward, the lifting member 42 lifts the bar, and after the bar height is higher than the limit member 3, it rolls on the limit member 3, and finally the bar rolls into the cutting area of ​​the cutting equipment.

[0033] refer to Figure 2The limiting member 3 is a right-angled trapezoidal plate. The limiting member 3 is fixed to the side wall of the placement frame 2 away from the lifting member 42 by bolts. The right-angled side of the limiting member 3 is perpendicular to the surface of the placement frame 2 used to place the bar to form a rigid block. The vertical force effectively prevents the bar from rolling due to gravity and prevents the bar from slipping off prematurely when it is not loaded. After the bar is lifted past the limiting member 3, it can roll smoothly along the inclined side to ensure that the bar can roll into the cutting area.

[0034] The implementation principle of this application embodiment is as follows: The operator places multiple rods on the placement rack 2 at one time. The system controls the cylinder output shaft to retract. The feeding block 44 moves with the cylinder output shaft, causing the rotating shaft 43 to rotate clockwise, thereby causing several feeding blocks 44 to rotate. The other end of the feeding block 44 causes the lifting member 42 to slide downward. The lifting member 42 lifts the rod. After the height of the rod is higher than the limit member 3, it rolls on the limit member 3. Finally, the rod rolls into the cutting area of ​​the cutting equipment. Then, the cylinder output shaft extends. The feeding block 44 moves with the cylinder output shaft, causing the rotating shaft 43 to rotate counterclockwise, thereby causing several feeding blocks 44 to rotate. The other end of the feeding block 44 causes the lifting member 42 to slide downward.

[0035] In summary, the system periodically controls the feeding mechanism 4 to lift the bar stock, achieving automated feeding. This allows workers a longer downtime after each feeding to perform other tasks, thus improving the time utilization rate of the workers.

[0036] Example 2: The difference between this embodiment and Embodiment 1 is that the feeding mechanism 4 includes a drive motor 401, a drive shaft 402, a driven shaft 403, and a conveyor belt 404. The drive shaft 402 and the driven shaft 403 are arranged parallel to each other. The drive shaft 402 and the driven shaft 403 are respectively installed through and rotatably on several placement racks 2 along the length of the frame 1. The output shaft of the drive motor 401 is fixed to the end of the drive shaft 402 by bolts. The output shaft of the drive motor 401 is coaxial with the drive shaft 402 to drive the drive shaft 402 to rotate. The drive motor 401 is fixed to one side wall of the placement rack 2 by bolts. Several partitions 8 are clamped along the length of the conveyor belt 404. The partitions 8 are all perpendicular to the surface of the conveyor belt 404 and are evenly spaced along the length of the conveyor belt 404. A receiving groove 9 for placing bars is formed between two adjacent partitions 8. The adjacent partitions 8 cooperate with each other to limit the bars. This solution does not require the setting of limiting parts 3.

[0037] The implementation principle of this application embodiment is as follows: the operator places multiple bars into several receiving slots 9 formed between several adjacent partitions 8, and then the system controls the drive motor 401 to rotate. The rotation of the drive motor 401 drives the drive shaft 402 to rotate, and the rotation of the drive shaft 402 drives the conveyor belt 404 to move, thereby moving the bars. The periodic rotation of the drive motor 401 ensures that the next bar is transported to the cutting area after the previous bar is cut by the cutting equipment, realizing automated feeding. This allows the operator to have a longer downtime to perform other tasks after feeding, improving the operator's time utilization rate.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
