Description

Technical Field

[0001] The utility model relates to the technical field of suspension conveyor lines, in particular to a stopper and a suspension conveyor system. Background Art

[0002] In many industries such as automobile production, construction machinery assembly, home appliance manufacturing, and electric bicycle production, suspension conveyor lines are often used for transporting materials, that is, conveying trolleys running along the suspension conveyor line track are used to carry materials such as tools and accessories. Among them, the friction wheel type conveying trolley is a widely used one. For example, in the suspension conveying device disclosed in patent CN201810001687.9, a friction wheel type conveying trolley is adopted. A turning plate for triggering the internal braking mechanism of the trolley is arranged at the front end of this friction wheel type conveying trolley. Due to the rhythm requirements in the production and assembly process, the materials need to be conveyed to the corresponding workstations according to the rhythm requirements. Therefore, a stopper needs to be set at a specific position in the track. When the trolley runs to a position close to the stopper, the air cylinder in the stopper pushes a linkage mechanism, so that the bottom end of the stopper linkage mechanism rotates from top to bottom, and the stop block arranged at the bottom end of the linkage also swings to the front of the turning plate along with the operation of the linkage mechanism. Subsequently, when the trolley runs to the predetermined position, the turning plate first contacts the stop block, thereby pushing down the turning plate, and the braking mechanism of the friction wheel type conveying trolley acts, so that it stops at the current position and will not move forward any more; when it is necessary to release the trolley, the air cylinder in the stopper contracts, pulling the linkage mechanism to swing in the reverse direction, so that the stop block is separated from the turning plate. At this time, the turning plate is no longer pressed, and under the action of the return spring inside the friction wheel type conveying trolley, the turning plate automatically flips up and resets, so that the braking mechanism is relaxed, and the conveying trolley can continue to run along the track.

[0003] In the process of implementing the present utility model, the inventor found that there are at least the following problems in the prior art:

[0004] In the existing stopper, since the linkage mechanism flips in the up and down directions, the air cylinder needs to overcome the gravity of the linkage mechanism, and the force is relatively large. A cylinder with a relatively large driving force needs to be configured. And because the structure of the linkage mechanism is relatively complex, the structure of the entire stopper is complex, and it has a large volume and a large weight, which causes inconvenience to production applications. Therefore, how to simplify the structure of the stopper is a problem to be solved. Summary of the Utility Model

[0005] The embodiment of the present utility model provides a stopper and a suspension conveyor system to solve the problems of complex structure, large volume, and large weight existing in the existing stopper.

[0006] To achieve the above object, on the one hand, an embodiment of the present utility model provides a stopper, comprising: a stopper frame installed on the side of the suspension line conveying track and a moving rod movably connected to the stopper frame; a driving device is further connected to the stopper frame, and the output end of the driving device is connected to the moving rod; the moving rod can move horizontally in the left-right direction; a stop block for stopping the conveying trolley on the suspension line conveying track is fixedly connected to the end of the moving rod.

[0007] On the other hand, this embodiment also provides a suspension conveying system, comprising a suspension line conveying track, a conveying trolley running along the suspension line conveying track, and the stopper as described above; a turning plate for triggering the braking system of the conveying trolley is provided at the front end of the conveying trolley; the stopper is connected to the side of the suspension line conveying track, and when the moving rod moves inward to the maximum limit position with respect to the suspension line conveying track, the stop block is located on the running track of the turning plate.

[0008] The above technical solution has the following beneficial effects:

[0009] In this technical solution, the stopper is arranged on the side of the suspension line conveying track. When it is necessary to stop the friction wheel type conveying trolley, the moving rod equipped with the stop block is driven by a cylinder to move horizontally from the outside of the track to the inside of the track, blocking in front of the friction wheel type conveying trolley. Subsequently, the stop block impacts the turning plate at the front end of the friction wheel type conveying trolley, causing the braking system to act, thereby stopping the operation of the friction wheel type conveying trolley. The moving part of this stopper moves horizontally, which is simpler and more reliable than the prior art method of realizing up and down flipping through a connecting rod. Therefore, it works stably, the overall structure is greatly simplified, the volume is smaller, the weight is lighter, and the noise is low, making it more suitable for use in the suspension conveying system.

[0010] At the same time, a hydraulic buffer is also integrated in this solution. It quickly stops the conveying trolley that continues to slide along the track after losing power through its own damping force, and reduces the impact of the conveying trolley on the stopper, achieving the purpose of protecting the stopper and the conveying trolley.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] As Figure 1 、 Figure 2 shown, an embodiment of the present utility model provides a stopper, including: a stopper frame 1 installed on the side of the suspension line conveying track and a moving rod 7 movably connected to the stopper frame 1; a driving device is further connected to the stopper frame 1, and the output end of the driving device is connected to the moving rod 7; the moving rod 7 can move horizontally in the left - right direction; a stop block 5 for stopping the conveying trolley on the suspension line conveying track is fixedly connected to the end of the moving rod 7.

[0019] As described above, the stopper of the prior art is arranged in the suspension line conveying track. When it is necessary to stop the friction - wheel type conveying trolley, the cylinder drives the link mechanism to swing from top to bottom, so that the end of the link mechanism drops from a position higher than the conveying trolley to a position directly in front of the conveying trolley. Thus, when contacting the conveying trolley, the internal braking system is triggered to stop the conveying trolley. In this structure, the link mechanism is relatively complex, and since it swings up and down, when swinging upward, it needs to overcome its own gravity, so a cylinder with a large driving force is required, resulting in a complex overall structure and difficulty in reducing the volume and weight.

[0020] To solve the aforementioned problems, in this technical solution, instead of using the up-and-down flipping link structure, the moving rod 7 equipped with the stop block 5 is pushed left and right in a translational manner. The stopper frame 1 is installed on the side of the suspension line conveying track (the suspension line conveying track includes the upper track 21 and the lower track 23). When it is necessary to stop the conveying trolley, as Figure 4 shown, the moving rod 7 horizontally extends into the inner side of the track from the side of the track and blocks in front of the conveying trolley. Then, when the flipping plate 33 provided at the front end of the vehicle body 31 contacts the stop block 5, under the resistance behind the stop block 5, the flipping plate 33 tilts backward, and the friction drive wheel 32 is pulled downward through the brake wire, so that the friction drive wheel 32 is separated from the friction rod 22. At this time, since the friction drive wheel 32 no longer has an attachment point, the conveying trolley loses the power to move forward, decelerates and stops. When it is necessary to release, the moving rod 7 is pulled in the reverse direction and retracts to the outside of the track, no longer blocking the conveying trolley. Therefore, the flipping plate 33 flips and resets in the reverse direction under the action of the spring, the brake wire is relaxed, the friction drive wheel 32 resets and rises to contact the friction rod 22, and the conveying trolley continues to move forward.

[0021] In this solution, the moving parts of the stopper move horizontally, which is much simpler than the prior art method of achieving up-and-down flipping through a link. Therefore, the overall structure is greatly simplified, with a smaller volume and lighter weight, and is more suitable for use in a suspension conveying system.

[0022] Furthermore, the driving device is a cylinder 11, or a hydraulic cylinder, or an electric push rod, or a gear-rack structure. These devices can all push the moving rod 7 to move horizontally to complete the predetermined action.

[0023] Furthermore, the driving device is a cylinder 11. The cylinder 11 includes a cylinder block and a push rod, and the running track of the push rod is parallel to the moving direction of the moving rod 7; the cylinder block is connected to the stopper frame 1, and the push rod is connected to the moving rod 7.

[0024] As described above, the movement of the moving rod 7 can adopt various driving methods. However, in order to match the existing production line, this technical solution preferably uses a cylinder 11 as the driving device. When the push rod extends, it pushes the second vertical rod 2 towards the inner side of the track, thereby driving the lower moving rod 7 towards the inner side of the track; when the push rod retracts, it pulls the moving rod 7 towards the outer side of the track.

[0025] Further, a flat plate 9 is also arranged between the push rod and the moving rod 7. A first vertical rod 8 is fixedly connected to the lower part of the flat plate 9, and the bottom end of the first vertical rod 8 is fixedly connected to the moving rod 7. A second vertical rod 2 is fixedly connected to the upper part of the flat plate 9, and the push rod is hinged to the second vertical rod 2. A guide wheel 12 is arranged on the flat plate 9, and a guide rod 10 is arranged on the stopper frame 1. The guide wheel 12 matches the guide rod 10, and the axial direction of the guide rod 10 is parallel to the running track of the push rod.

[0026] For the convenience of layout, the moving rod 7 is not directly connected to the driving device, but as Figure 2 shown, the first vertical rod 8, the flat plate 9 and the second vertical rod 2 are successively connected to the moving rod 7, so that the push rod is hinged to the second vertical rod 2. At the same time, the flat plate 9 also has a function, that is, the guide wheel 12 can be arranged thereon. The cooperation between the guide wheel 12 and the guide rod 10 provides guidance and limit for the movement of the moving parts, and avoids the deviation of the moving rod 7 during the horizontal movement.

[0027] Further, a V-shaped groove is formed at the rim of the guide wheel 12, the guide rod 10 is a round rod, and the guide rod 10 is in contact with both groove surfaces of the V-shaped groove at the same time, that is, the guide rod 10 is "embedded" into the V-shaped groove. This kind of cooperation method can achieve precise limit and effectively ensure that the flat plate 9 will not move in the up and down direction during the translation process.

[0028] Further, there are two guide rods 10 in total, and there are two groups of guide wheels 12 in total. Each two guide wheels 12 arranged side by side in the left-right direction form a group of guide wheels 12, and each guide rod 10 matches a group of guide wheels 12; the two guide rods 10 are arranged in parallel, and all the guide wheels 12 are arranged between the two guide rods 10. Arranging the two groups of guide wheels 12 between the two guide rods 10 can restrict the flat plate 9 in the front-back direction, so that it will not move back and forth, thereby ensuring the correct movement of the moving rod 7.

[0029] Further, a plate-shaped mounting plate 3 is arranged on the stopper frame 1, and a plurality of through holes for penetrating connecting screws are formed in the mounting plate 3 to realize the threaded connection with the suspension line conveying track.

[0030] Further, the stop block 5 is a rectangular block arranged in the front-back direction, and a convex arc surface 6 is arranged at the bottom of the rear end of the stop block 5.

[0031] After the rear end of the rectangular block presses the turning plate 33, the turning plate 33 can be gradually tilted to the horizontal position along the arc surface 6. The arc surface 6 can avoid always contacting the plate surface of the turning plate 33 during this process, evenly bear the force, and avoid scratching during the contact process.

[0032] Furthermore, a hydraulic buffer 4 is also provided on the moving rod 7. The hydraulic buffer 4 is arranged in parallel above the stop block 5, and the rear end of the hydraulic buffer 4 protrudes beyond the rear end of the stop block 5.

[0033] After the stop block 5 causes the turning plate 33 to completely fall, the conveying trolley loses the power to move forward. However, under the action of inertia, the conveying trolley will continue to slide forward for a certain distance and then contact the hydraulic buffer 4 until it stops. The frictional force between the conveying trolley and the track and the damping force of the hydraulic buffer 4 are fully utilized to reduce the impact of the conveying trolley on the stopper, achieving the purpose of protecting the stopper and the conveying trolley. Without this hydraulic buffer 4, it is possible that the conveying trolley still has a certain speed when it contacts the stopper again after the turning plate 33 falls, that is, it is possible that the vertical plate 34 directly impacts the stop block 5, which will cause damage to the conveying trolley and the stopper.

[0034] As Figure 3 、 Figure 4 shown, an embodiment of the present invention also provides a suspension conveying system, including a suspension line conveying track, a conveying trolley running along the suspension line conveying track, and a stopper as described above. A turning plate 33 for triggering the braking system of the conveying trolley is provided at the front end of the conveying trolley. The stopper is connected to the side of the suspension line conveying track, and when the moving rod 7 moves to the maximum limit position towards the inner side of the suspension line conveying track, the stop block 5 is located on the running track of the turning plate 33.

[0035] The suspension line conveying track includes an upper track 21 and a lower track 23. The upper track 21 is used to suspend the friction rod 22, and the friction rod 22 is used to contact the friction drive wheel 32 to generate frictional force to push the conveying trolley to run. The concave structure of the lower track 23 is used to support the track wheel 35 of the conveying trolley, and the track wheel 35 is used to suspend the conveying trolley to ensure that the conveying trolley does not fall off. The upper track 21 and the lower track 23 are arranged parallel to each other up and down, and a fixed clamp 24 is provided at each predetermined distance for fixedly connecting with the upper track 21 and the lower track 23 to ensure the stability of the entire suspension line conveying track. For stability, there are two mounting plates 3 on the stopper, corresponding to the heights of the upper track 21 and the lower track 23 respectively. During use, first connect the two mounting plates 3 to the upper track 21 and the lower track 23 through bolts respectively, and then conduct debugging to ensure that the moving rod 7 can touch the turning plate 33 when it extends.

[0036] Further, when the moving rod 7 moves to the innermost limit position of the suspension line conveying track, the width of the turning plate 33 blocked by the stop block 5 is less than half of the width of the turning plate 33. That is, the stop block 5 does not need to completely block the turning plate 33, and does not even need to move to the center of the turning plate 33. Instead, it only needs to slightly block the turning plate 33 so that the turning action can be completed when they come into contact. In this way, when the vehicle is released, the moving rod 7 only needs to move a small distance outward, and the stop block 5 will no longer touch the turning plate 33, and the conveying trolley can quickly resume operation. Therefore, the response action is very fast and is very suitable for realizing continuous vehicle release, thereby improving the vehicle release efficiency of the conveying line.
