[0001] The utility model relates to the technical field of automation, in particular to a stopper on a roller line. Background Art
[0002] A roller line is a conveying device used in the industrial and logistics fields. It moves items through rollers, which are installed on a horizontal and inclined conveyor belt. Roller lines are widely used in production lines, warehouses, and logistics centers for efficiently and reliably handling various items.
[0003] During the actual use of the roller line, a stopper is required, so a stopper on the roller line will be used. The stopper is a device that can control and guide the position and movement of items on the roller line, helping to manage the flow and sorting of items, optimize the production process, and support the operation of the automation system. By using the stopper, the overall performance of the roller line can be improved.
[0004] In the prior art, when the stopper is working, after the controller receives the blocking signal, it drives the electric push rod to extend, raising the blocking plate to block the items on the roller line. When it is necessary to release the items, the controller controls the electric push rod to retract again, and the blocking plate drops. However, since the stopper converts the horizontal force, the material and the stopper need to be placed vertically. The roller lines on the AGV and the buffer rack affect the power of the stopper to move up and down, and the use effect in all cases cannot be achieved, affecting the production efficiency. Summary of the Utility Model
[0005] In order to make up for the above deficiencies, the utility model provides a stopper on a roller line, aiming to improve the problem that the vertical placement of the material and the stopper in the prior art affects the power of the stopper to move up and down.
[0006] In order to achieve the above object, the utility model adopts the following technical scheme: A stopper on a roller line includes a frame.

Specific embodiments
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0025] Refer to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: A stopper on a roller line, including a frame 12, a fixed seat 11 is fixedly connected to the rear side of the left end inside the frame 12, a microswitch 1 is fixedly connected to the front side of the top of the fixed seat 11, a first wheel seat 4 is fixedly connected to the left rear end of the top of the fixed seat 11, and a second wheel seat 5 is fixedly connected to the right rear end of the top of the fixed seat 11. The fixed seat 11 is used to fix the microswitch 1. A clamping seat 14 is fixedly connected to the middle and lower part of the right side of the outer wall of the first wheel seat 4, and the other end of the clamping seat 14 is fixedly connected to the middle and lower part of the left side of the outer wall of the second wheel seat 5. A second telescopic shaft 10 is penetrated through the middle part of the front side of the outer wall of the clamping seat 14. The position of the second telescopic shaft 10 is fixed by the clamping seat 14. A rope hook 2 is fixedly connected to the front end of the second telescopic shaft 10. A first spring 3 is penetrated through the middle part of the outer wall of the second telescopic shaft 10. A pulley 6 is installed at the right rear end of the outer wall of the first wheel seat 4, and the other end of the pulley 6 is installed at the left rear end of the outer wall of the second wheel seat 5. The rope hook 2 is used to fix the steel wire rope 9. By using the function of the pulley 6, the moving track of the steel wire rope 9 is limited to realize the stable movement of the steel wire rope 9;
[0026] Specifically, during the working process of the stopper device, first apply a certain thrust to the second telescopic shaft 10. Under the combined action of the traction of the steel wire rope 9 and the limiting function of the pulley 6, the first telescopic shaft 7 is pulled downward. During this process, the first wheel seat 4 and the second wheel seat 5 play a fixing role for the pulley 6. As the first telescopic shaft 7 is pulled downward, the materials originally blocked above can pass through smoothly. When the second telescopic shaft 10 reaches the predetermined position, it will trigger the microswitch 1, thereby sending a signal to remove the thrust applied to the second telescopic shaft 10. Under the elastic force of the first spring 3, the second telescopic shaft 10 automatically completes the reset action and returns to the initial working state.
[0027] Reference Figure 1 Figure 3 and Figure 4 A positioning seat 8 is fixedly connected to the left end of the middle upper part of the rear side of the outer wall of the frame 12, a telescopic shaft 7 is penetrated at the bottom of the outer wall of the positioning seat 8, and the telescopic shaft 7 is fixed by the positioning seat 8. A spring 2 13 is penetrated at the middle of the outer wall of the telescopic shaft 7, and a steel wire rope 9 is fixedly connected to the bottom of the telescopic shaft 7. The other end of the steel wire rope 9 is fixedly connected to the top of the rope hook 2, and the telescopic shaft 7 and the telescopic shaft 2 10 are connected by the steel wire rope 9, and the spring 2 13 is used to realize the reset of the telescopic shaft 7;
[0028] Specifically, during operation, the telescopic shaft 2 10 is connected to the telescopic shaft 1 7 through the wire rope 9. The positioning function of the positioning seat 8 ensures that the telescopic shaft 1 7 can be fixed at a specific position to achieve good linkage. When the telescopic shaft 1 7 needs to move downward, it will break away from the blocking state of the material, allowing the material to pass smoothly. When the telescopic shaft 2 10 at the bottom no longer applies thrust, the telescopic shaft 1 7 will automatically return to its original position with the help of the elastic force of the spring 2 13, and block the material again, which not only improves work efficiency, but also ensures the stability and reliability of the entire system.
[0029] Reference Figure 1 and Figure 3 The bottom of the frame 12 is fixedly connected with a support column 15, and the left and right sides of the inside of the frame 12 are fixedly connected with a cross bar 19, which plays a supporting role for the frame 12; the left and right sides of the top of the outer wall of the frame 12 are provided with threaded holes 16, and the external bolts are fixed by the threaded holes 16;
[0030] Specifically, the support column 15 at the bottom of the frame 12 supports the frame 12 , the frame 12 is connected via the cross bar 19 , and the external bolts are fixed via the threaded holes 16 .
[0031] Reference Figure 1 and Figure 4 A connecting rod 17 is fixedly connected to the middle and lower part of the inner wall of the support column 15, and a threaded hole 18 is opened on the rear side of the outer wall of the connecting rod 17. The connecting rod 17 supports the support column 15, and a bolt is fixed to the connecting rod 17 through the threaded hole 18;
[0032] Specifically, a plurality of support columns 15 are connected by a connecting rod 17 , and a threaded hole 18 is used to install the fixing bolts.
[0033] Working principle: When the blocker device is working, a thrust is applied to the second telescopic shaft 10. Under the action of the steel wire rope 9 and the limit of the pulley 6, the first telescopic shaft 7 is pulled down. The first wheel seat 4 and the second wheel seat 5 play a role in fixing the pulley 6. After the first telescopic shaft 7 is pulled down, it no longer blocks the upper material. After the second telescopic shaft 10 is in place, the microswitch 1 is triggered. After removing the thrust of the second telescopic shaft 10, the second telescopic shaft 10 is reset by the first spring 3;
[0034] When the second telescopic shaft 10 is working, the first telescopic shaft 7 is connected through the steel wire rope 9. By the action of the positioning seat 8, the position of the first telescopic shaft 7 is fixed to realize the linkage between the structures. The first telescopic shaft 7 moves downward and no longer blocks the material. After removing the thrust of the second telescopic shaft 10 at the bottom, the first telescopic shaft 7 is reset by the second spring 13 and blocks the material again.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
