Description

Technical Field

[0001] This application is applied to the field of automated conveying, and specifically relates to a heavy-duty stopper and a roller conveyor line including the stopper. Background Technology

[0002] On automated conveyor lines, stoppers are required to stop the load on the conveyor line at a preset position. In the existing technology, stoppers are mostly directly installed on the conveyor line. In some heavy-load working conditions, heavy loads will cause a large impact on the stoppers, and the stoppers will transmit the impact force to the conveyor line, causing the conveyor line to vibrate, which will affect the conveying and stopping of the load. Summary of the Invention

[0003] In view of the above reasons, this application discloses a heavy-duty stop device, including a fixed bracket, a stop plate, a motor, an eccentric rod, a roller, and a roller housing. The motor is fixedly mounted on the fixed bracket, and the shaft end of the motor is connected to one end of the eccentric rod. The motor can drive the eccentric rod to rotate in a vertical plane. The other end of the eccentric rod is freely disposed with the roller, which is placed in the roller housing. The roller can be horizontally displaced relative to the roller housing. The stop plate is disposed above the roller housing. The motor drives the eccentric rod to rotate, thereby causing the stop plate to move up and down in the vertical direction.

[0004] Preferably, the roller receiving member has a roller receiving groove, the opening direction of the roller receiving groove is a horizontal direction close to the motor, the length direction of the roller receiving groove is a horizontal direction, and the roller is placed in the roller receiving groove.

[0005] Preferably, a connecting plate is fixedly provided above the roller receiving component, and vertical guide rails are fixedly connected to both ends of the connecting plate. The top end of the guide rail is fixedly connected to the stop plate. The fixed bracket is provided with a guide rail receiving groove at the corresponding position of the guide rail, and the guide rail is placed in the guide rail receiving groove.

[0006] Preferably, a slider is provided in the guide rail receiving groove, and the slider is connected to the guide rail. The guide rail can be displaced vertically relative to the slider.

[0007] Preferably, the lower end of the fixed bracket is provided with an adjustable support foot, which is used to adjust the height of the fixed bracket.

[0008] Preferably, it also includes a support frame, one end of which is fixedly connected to the ground, and the other end of which is connected at an angle to the fixed bracket.

[0009] This application also discloses a roller conveyor line, including a roller conveyor and a heavy-duty stopper as described above. The heavy-duty stopper is disposed below the roller conveyor, and the stopper plate is located between adjacent rollers of the roller conveyor. When the stopper plate is in a high position driven by a motor, the height of the stopper plate is higher than the conveying plane of the roller conveyor. When the stopper plate is in a low position driven by a motor, the height of the stopper plate is lower than the conveying plane of the roller conveyor.

[0010] The advantage of this application is that the stop plate is driven vertically up and down by a motor and an eccentric wheel. Driven by the motor, it is more stable than the cylinder cycle. The structure is simple. The heavy-duty stop device is set with a separate fixed bracket and directly connected to the ground. It will not transmit force to the conveyor line and will not affect the conveyor line. It can be placed in any position and is suitable for heavy-duty working conditions.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 3 As shown, the fixed bracket 1 is an aluminum profile metal bracket. The motor 2 is fixedly connected to the fixed bracket 1 through a motor bracket. The shaft end of the motor 2 is fixedly connected to one end of the eccentric rod 3. The motor 2 can drive the eccentric rod 3 to rotate in the vertical plane around the shaft end of the motor 2. The other end of the eccentric rod 3 is freely provided with a roller 4, which can rotate freely around its axis. The roller 4 is set in a roller receiving part 5, which is a bent metal part. The roller 4 can make horizontal displacement within the roller receiving part 5, and the vertical displacement of the roller 4 relative to the roller receiving part 5 is restricted. A stop is connected above the roller receiving part 5. Plate 6, the stop plate 6 has a stop surface 601, the stop surface 601 is used to contact the load on the conveyor line and block the load. When the motor 2 drives the eccentric rod 3 to rotate, the roller 4 also moves in a circular motion on the vertical plane relative to the shaft end of the motor 2. The roller 4 drives the roller housing 5 to move up and down in the vertical direction, and at the same time drives the stop plate 6 to move up and down in the vertical direction. When the motor 2 drives the roller 4 to the low position in the vertical height, the stop plate 6 is in the low position release state. When the motor 2 drives the roller 4 to the high position in the vertical height, the stop plate 6 is in the high position stop state.

[0021] In some implementations, such as Figures 1 to 3 As shown, the roller receiving component 5 has a roller receiving groove 501. The opening direction of the roller receiving groove 501 is horizontal, which is close to the side of the motor 2. The length direction of the roller receiving groove 501 is horizontal. As the motor 2 drives the eccentric rod 3 to rotate, the roller 4 can be placed in the roller receiving groove 501 for horizontal displacement, while driving the roller receiving component 5 to move up and down.

[0022] In some implementations, such as Figures 1 to 3As shown, a connecting plate 7 is fixedly installed above the roller receiving component 5. The length direction of the connecting plate 7 is horizontal. Guide rails 8 are fixedly connected to both sides of the connecting plate 7. The guide rails 8 are linear guide rails and are perpendicular to the ground. The guide rails 8 are made of a rigid material with a certain strength. The top of the guide rails 8 is fixedly connected to the back side of the stop plate 6. That is, the roller receiving component 5 is fixedly connected to the stop plate 6 through the connecting plate 7 and the guide rails 8, so that the stop plate 6 and the roller receiving component 5 move up and down synchronously. The fixed bracket 1 has a guide rail receiving groove 101 at the corresponding position of the guide rail 8. The opening direction of the guide rail receiving groove 101 is horizontal, away from the side of the motor 2. The guide rail 8 is placed in the guide rail receiving groove 101.

[0023] In some implementations, such as Figures 1 to 3 As shown, a slider 9 is provided in the guide rail receiving groove 101. The slider 9 is connected to the corresponding guide rail 8. The slider 9 and the guide rail 8 work together to guide the stop plate 6 vertically.

[0024] In some implementations, such as Figures 1 to 2 As shown, the lower end of the fixed bracket 1 is provided with an adjustable support leg 10. The adjustable support leg 10 can adjust the height of its bottom end relative to its upper end, thereby adjusting the height of the fixed bracket 1 to adjust the highest / lowest height of the stop plate 6.

[0025] In some implementations, such as Figures 1 to 2 As shown, a support frame 11 is provided on the side of the fixed bracket 1 near the back of the stop plate 6. One end of the support frame 11 is fixedly connected to the ground, and the other end of the support frame 11 is connected to the fixed bracket 1 at an angle. The support frame 11 plays the role of supporting and sharing the horizontal force. When the stop plate 6 is impacted by the horizontal force, the support frame 11 can strengthen the fixed bracket 1 and make the device more stable.

[0026] like Figure 4 A roller conveyor line is shown, and reference is made to... Figures 1 to 3The roller conveyor 12 has several equally spaced rollers 1201. The rotation of the rollers 1201 acts on the load, so that the load is conveyed on the roller conveyor 12. The lower end of the heavy-duty stopper is fixedly connected to the ground through adjustable support feet 10 and support frame 11. The upper end of the fixed bracket 1 is detachably connected to the profile of the roller conveyor 12. The position of the stop plate 6 is located between adjacent rollers 1201. The rollers 1201 will not interfere with the vertical displacement of the stop plate 6. When the heavy-duty stopper should be in the release position, the motor 2 drives the eccentric rod 3 to rotate until the roller 4 is in the lowest position. The roller 4 drives the roller housing 5 to simultaneously drive the stop plate 6 to the lowest position. The height of the stop surface 601 is lower than the conveying plane of the roller conveyor 12. The stop plate 6 does not affect the operation of the load on the roller conveyor 12. When the heavy-duty stopper is in the stop position, the motor 2 drives the eccentric rod 3 to rotate until the roller 4 is in the highest position. The roller 4 drives the roller housing 5 to simultaneously drive the stop plate 6 to the highest position. The height of the stop surface 601 is higher than the conveying plane of the roller conveyor 12. The stop plate 6 blocks the load on the roller conveyor 12. During the stop process, the impact of the load on the stop plate 6 will be distributed by the fixed bracket 1 and the support frame 11, and will not affect the roller conveyor 12.
