[0002] Nowadays, automated production logistics lines for frame longitudinal beams generally tend to use conveyor rollers as key auxiliary devices to promote the automated transfer process. This device, with its long-distance and efficient transmission capabilities, realizes the rapid flow of frame longitudinal beams within the workshop. The conveyor roller is not only fast in operation, but also safe and reliable. Its segmented control feature allows the conveying speed to be adjusted according to the specific needs of each workstation, thereby being able to flexibly adapt to and optimize the production rhythm. Therefore, it has been widely used in automated production logistics lines for frame longitudinal beams.

[0015] The double longitudinal beam end positioning device described in the utility model is as follows: Figure 1-5 As shown, the mounting frame 1 includes a first vertical movement cylinder 2 disposed vertically above the mounting frame 1. A first vertical movement plate 3 capable of vertical lift is mounted on the piston rod of the first vertical movement cylinder 2. Vertical guide rails 4 are disposed on either side of the mounting frame 1. Sliders 5, which cooperate with the guide rails 4, are mounted at both ends of the first vertical movement plate 3 in the longitudinal direction. The extension and retraction of the piston rod of the first vertical movement cylinder 2 can drive the first vertical movement plate 3 to move vertically upward and downward.

[0016] Two sets of positioning mechanisms arranged side by side are installed on the front side of the first vertical moving plate 3. The positioning mechanisms can position the longitudinal direction of the longitudinal beam on the conveyor roller. Each positioning mechanism includes a baffle 6. The baffle 6 is arranged parallel to the first vertical moving plate 3. A guide column 7 is installed on the baffle 6. The first vertical moving plate 3 is provided with a guide sleeve 8 that cooperates with the guide column 7. A limit plate 9 is installed on one end of the guide column 7 that passes through the guide sleeve 8. The diameter of the limit plate 9 is larger than the inner diameter of the guide sleeve 8 to prevent the guide column 7 from separating from the guide sleeve 8.

[0017] Buffer blocks 10 are also installed on the inner sides of both ends of the baffle 6 in the length direction. When the baffle 6 moves close to the first vertical sliding plate 3, the buffer blocks 10 will contact the first vertical sliding plate 3, thereby realizing the corresponding buffering function.

[0018] The mounting frame 1 includes a horizontally arranged top rod 11 and bottom rod 12, with vertical rods 13 connected to each other on both sides of the top rod 11 and the bottom rod 12. The first vertical movement cylinder 2 is mounted on the top rod 11, and the guide rail 4 is mounted on the vertical rod 13. A connecting plate 14 is provided at the bottom of the vertical rod 13, a first diagonal brace 15 is provided between the connecting plate 14 and the vertical rod 13, and a second diagonal brace 16 is provided between the vertical rod 13 and the top rod 11. The connecting plate 14 can be detachably mounted on the frame of the conveyor roller by bolts.

[0019] Furthermore, in order to achieve corresponding elastic buffering when the longitudinal beam contacts the baffle 6, a guide shaft 17 is installed on the inner side of the baffle 6, and a through hole is opened on the first vertical moving plate 3 for the guide shaft 17 to pass through. A spring 18 is mounted on the outer periphery of the guide shaft 17 between the first vertical moving plate 3 and the baffle 6. The diameter of the spring 18 is larger than the diameter of the through hole. When the baffle 6 moves close to the first vertical moving plate 3, the spring 18 will be compressed.

[0020] In order to realize the monitoring of the contact between the longitudinal beam and the baffle 6, a sensing plate 19 is installed inside the baffle 6, and a slot is opened on the first vertical movable plate 3 for allowing the sensing plate 19 to pass through. Corresponding to the position of the sensing plate 19, a first proximity switch 20 is also installed on the inner side of the first vertical movable plate 3. When the longitudinal beam moves on the conveyor roller until it contacts the baffle 6, it will push the baffle 6 to move a short distance, and the sensing plate 19 will extend synchronously, which can be monitored by the first proximity switch 20, indicating that the longitudinal beam has reached the position of the end positioning device at this time.

[0021] In order to realize the monitoring of the moving position of the vertical lifting of the baffle 6, an upper limit bracket 21 and a lower limit bracket 22 are also provided on the side of the mounting frame 1. The upper limit bracket 21 is installed with a second proximity switch 23, and the lower limit bracket 22 is installed with a third proximity switch 24. The second proximity switch 23 and the third proximity switch 24 can detect the vertical lifting of the first vertical moving plate 3.

[0022] When the double longitudinal beams on the conveyor roller need to be end-limited, the piston rod of the first vertical movement cylinder 2 extends to drive the baffle 6 down to the roller position. The longitudinal beam contacts the baffle 6 during the conveying process and pushes the baffle 6 to move a short distance closer to the first vertical movement plate 3. At this time, the first proximity switch 20 receives the in-position signal. After the longitudinal beams on both sides contact the baffle 6, the conveyor roller is controlled to stop conveying. Under the limiting action of the baffle 6, the end limit of the double longitudinal beams can be achieved, so that they can be transferred to other processing steps through the grasping equipment. If the longitudinal beam at this position does not need to be end-limited, the piston rod of the first vertical movement cylinder 2 can be retracted to drive the baffle 6 upward and make room for the longitudinal beam to move. The longitudinal beam can then be driven by the rotation of the roller and pass through the mounting frame 1 for normal conveying.

[0023] The structure of the above-mentioned mounting frame 1 is relatively stable, and is composed of a horizontally arranged top rod 11, a bottom rod 12 and a connected vertical rod 13. Through the reinforcement of the first diagonal brace 15 and the second diagonal brace 16, the entire device structure is stable and can withstand large longitudinal and lateral forces, thereby ensuring safety and stability during operation.

[0024] Buffer blocks 10 are installed on the inner sides of both ends of the baffle 6 in the longitudinal direction. When the baffle 6 moves close to the first vertical sliding plate 3, the buffer blocks 10 will contact the first vertical sliding plate 3, playing a buffering role, avoiding hard collision between the baffle 6 and the first vertical sliding plate 3, protecting the longitudinal beam from damage, and extending the service life of the device.

[0025] In addition, the device is also equipped with intelligent detection elements such as the induction plate 19, the first proximity switch 20, the second proximity switch 20, and the third proximity switch 24, which can monitor the position of the baffle 6 and the first vertical sliding plate 3 in real time, as well as the vertical lifting state of the first vertical sliding plate 3, making it possible to realize automatic control of the device. This design enables the device to automatically adjust the position and height of the baffle according to production needs, further improving the degree of automation of the production line. The device can be directly installed on the conveyor roller frame without the need for large-scale modification of the existing production line, reducing installation costs and time. At the same time, the device has a reasonable structural design and is easy to disassemble and repair, reducing subsequent maintenance costs.

[0026] When the longitudinal beam contacts the baffle 6 during the conveying process, the baffle 6 will rebound due to the setting of the spring 18, and at the same time push the longitudinal beam to move in the opposite direction for a short distance. For the transfer of double longitudinal beams on the conveyor roller, the baffles 6 on both sides will move in the opposite direction for different distances after contacting the longitudinal beams, resulting in uneven positioning of the ends of the double longitudinal beams, affecting subsequent processing procedures.

[0027] To solve the above problems, Figure 7 and Figure 8As shown, the bottom of the mounting frame 1 is detachably connected to the support frame 26 through an elastic pad 25, and an end secondary positioning mechanism is provided on the support frame 26 on the rear side of the mounting frame 1. The support frame 26 can be fixed to the conveyor roller frame by bolts, and the mounting frame 1 and the end secondary positioning mechanism are arranged one after the other. The baffle 6 on the mounting frame 1 only realizes contact with the longitudinal beam and stops it, and then the end of the double longitudinal beam is adjusted and aligned through the action of the end secondary positioning mechanism.

[0028] The end secondary positioning mechanism includes a vertical frame 27, on which is mounted a second vertical cylinder 28. The piston rod of the second vertical cylinder 28 is provided with a second vertical plate 29. The vertical frame 27 is provided with a vertical slot 30 that cooperates with the second vertical plate 29. The second vertical cylinder 28 can drive the second vertical plate 29 to move vertically upward and downward. A horizontally arranged transverse cylinder 31 is also mounted below the second vertical plate 29. The piston rod of the transverse cylinder 31 is provided with a secondary positioning plate 32. When the piston rod of the transverse cylinder 31 is extended, it can drive the secondary positioning plate 32 to move forward to the bottom position of the baffle 6.

[0029] When the above-mentioned device realizes the end positioning of the double longitudinal beams, the first vertical moving plate 3 is first lowered to the specified height position, allowing the moving longitudinal beam to contact the baffle 6, so that the longitudinal beam stops moving. In the process of the longitudinal beam contacting the baffle 6, the second vertical moving plate 29 is located on the upper side of the first vertical moving plate 3 and will not interfere with the horizontal movement of the baffle 6. When the longitudinal beam is separated from the baffle 6, the first proximity switch 20 receives a signal, controls the first vertical moving plate 3 to move up to the initial height position, and the second vertical moving plate 29 is lowered to the specified height. After that, the piston rod of the transverse cylinder 31 is extended, driving the secondary positioning plate 32 to move and contact with the end of the double longitudinal beams, thereby realizing the end alignment of the double longitudinal beams. In the above structure, the mounting frame 1 and the vertical frame 27 are arranged separately, and the baffle 6 on the mounting frame 1 contacts the longitudinal beam to stop its movement. The setting of the elastic pad 25 can effectively reduce the shaking caused by the impact of the longitudinal beam. The vertical frame 27 can be fixed on the support frame 26 to enhance the overall stability of the end secondary positioning mechanism, reduce the instability caused by the impact of the longitudinal beam, and effectively improve the accuracy of the secondary positioning of the longitudinal beam end.
