Description

Technical Field

[0001] The invention relates to the technical field of automated conveying, and in particular to a stopping structure of a material conveying line. Background Art

[0002] When transporting materials, a conveyor line is usually used. The movement of the frame on the conveyor line can transport the materials to the storage area, reducing the labor intensity of the workers. In order to facilitate the orderly deployment of material movement, the frame usually needs to stop during operation.

[0003] In the prior art, a parking structure is provided to realize parking. Figure 1-5 The parking structure usually includes a front frame 91 and a tail shovel 81 installed at the front and rear ends of the frame 7, and a matching stop assembly, wherein the stop assembly includes two front and rear mounting plates 10 fixed to one side of the linear track 1, and the front and rear mounting plates 10 are respectively connected to a front stop block 16 and a rear stop rod 17 through a cylinder 12; in actual operation, when the parking action is performed, the two frames 7 following each other will have an accumulation effect, that is, the front frame 91 of the rear frame will overlap the tail shovel 81 of the front frame, and the front and rear cylinders 12 on the linear track 1 are respectively controlled by two independent signals, and the stop block 16 and the rear stop rod 17 respectively block the front frames 91 of the two frames 7, thereby realizing the parking action.

[0004] In actual operation, since the two mounting plates 10 of the stop assembly are far apart, two independent signals are required for control, making it difficult to achieve complete synchronization. In addition, when the front and rear adjacent frames 7 are stopping, the front frame 91 of the rear frame hits the tail shovel 81 of the front frame, causing a slight change in the positions of the front and rear frames 7. As a result, when the rear stop rod 17 intervenes, the position of the front frame 7 deviates, and the rear stop rod 17 and the front frame 7 are stuck with each other, causing the entire frame to be unable to resume normal movement, affecting the normal operation of the production line. Summary of the invention

[0005] The object of the present invention is to provide a stopping structure of a material conveying line and a material conveying line.

[0006] The technical problem solved by the present invention is: since the two mounting plates of the stop block assembly are far apart, two independent signals are required for control, which makes it difficult to achieve complete synchronization, and during the stopping process of the front and rear adjacent frames, the front frame of the rear frame may collide with the tail shovel of the front frame, causing a slight change in the positions of the front and rear frames, resulting in the front frame deviating from the position when the rear stop block intervenes, and the stop block and the front frame are stuck with each other, causing the entire frame to be unable to resume normal movement, affecting the normal operation of the production line.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example 1

[0048] See also Figure 6-9 As shown, the present invention is a stopping structure of a material conveying line, which is used to stop a frame 7 running on a line track 1 of the material conveying line. It includes a front frame assembly, a tail shovel assembly and a stop assembly.

[0049] The front frame assembly is mounted on the travel end of the vehicle frame 7. A stopper 9 is provided on the front frame assembly.

[0050] The tail shovel assembly is mounted on the frame 7 at one end away from the traveling end. A limiting portion 8 matched with the stop portion 9 is provided on the tail shovel assembly.

[0051] The stop assembly is installed on the material conveying line body and is used to stop the stop part 9.

[0052] The stop assembly includes two mounting plates 10 symmetrically arranged on both sides of the linear track 1. A telescopic cylinder 12 is mounted on the mounting plate 10. The actuator rod of the telescopic cylinder 12 is rotatably connected to a connecting member 13. A front stop member 11 matching the stop portion 9 is mounted on the connecting member 13.

[0053] It should be noted that

[0054] 1. The stop portion 9 cooperates with the limiting portion 8, that is, the limiting portion 8 of the front frame 7 matches the stop portion 9 of the rear frame 7. When the front frame 7 is stopped, the rear frame 7 stops by cooperating with the limiting portion 8 of the front frame 7 through the stop portion 9 of the rear frame 7.

[0055] 2. The two front stoppers 11 in the stop assembly act on the stop portion 9 of the frame 7 from both sides of the linear track 1 to stop the frame 7. The front stoppers 11 directly act on the stop portion 9 without contacting or interfering with the frame 7 body.

[0056] 3. The moving direction of the stop portion 9 is perpendicular to the rotation plane of the front stop member 11. This can ensure that the front stop member 11 does not interfere with the vehicle frame 7 as much as possible, and can also improve the accuracy of the stopping action.

[0057] In actual operation, when parking is performed, the two frames 7 following each other will have an accumulation effect, that is, the stop part 9 of the rear frame 7 will overlap the tail shovel limit part 8 of the front frame 7, and the two telescopic cylinders 12 on both sides of the linear track 1 are controlled by a signal, and the front stop part 11 is flipped, so that the stop part 9 of the front frame 7 is overlapped with the front stop part 11, and the front frame 7 stops, thereby realizing the parking action.

[0058] The two symmetrical stop parts can be controlled by the same signal, which saves the number of solenoid valves of the cylinder and reduces costs; it can realize the simultaneous action of the two telescopic cylinders 12 and improve the stability of control; the two telescopic cylinders 12 jointly control the stopping of the frame 7, which can increase the stopping force of the stopping structure and improve the stability and accuracy of parking.

[0059] Example 2

[0060] Considering that the travel of the front stopper 11 may interfere with the travel of the frame 7, in this embodiment, the front frame assembly includes an extension frame 14. One end of the extension frame 14 is mounted on the travel end of the frame 7, and the other end is provided with a mounting shaft 15. Stoppers 9 are mounted on both ends of the mounting shaft 15. The two stoppers 9 correspond to the two front stoppers 11 one by one.

[0061] The tail shovel assembly includes an extension frame 2. The extension frame 2 is mounted on the vehicle frame 7 at one end away from the traveling end. The limiting portion 8 is mounted on the extension frame, and the limiting portion 8 cooperates with two stop portions 9.

[0062] It should be noted that, by providing the mounting shaft 15 and providing the stop portions 9 at both ends of the mounting shaft 15, the travel of the front stop member 11 during rotation can be effectively reduced, and excessive swinging of the front stop member 11 and interference or collision with the frame 7 body can be avoided as much as possible; correspondingly, since the two stop portions 9 are located on both sides of the mounting shaft 15, the structure of the tail shovel assembly also needs to correspond, and can be implemented in the form of the mounting shaft 15 similar to the front frame assembly, or the limiting portion 8 can be directly provided with a long strip, and a structure matching the stop portion 9 can be provided on the long strip.

[0063] Specifically, in actual use, the stopper 9 can be provided with a wheel structure, that is, two wheels are installed at both ends of the mounting shaft 15, and the mounting shaft 15 can be rotatably arranged between the extension frame 14. Accordingly, the front stopper 11 should have a response structure that can block the wheel body, so as to have a stopping effect on the wheel body. Secondly, the limiting part 8 should include a limiting groove for accommodating the wheel body, and the limiting groove cooperates with the wheel body to realize the contact between the front and rear frames 7.

[0064] The symmetrically arranged stop parts avoid the need for the front stop part 11 to extend to the middle position of the frame 7. As long as the front frame assembly of the previous frame 7 passes through the area of ​​the front stop part 11, the telescopic cylinder 12 can be immediately actuated to return the front stop part 11 to the parking position, which is conducive to the timely stopping of the next frame 7 without the occurrence of a truck situation, thereby reducing the maintenance cost of the production line.

[0065] Example 3

[0066] This embodiment discloses a material conveying line, including a line track 1, a plurality of vehicle frames 7 and the stop structure in Embodiment 1 or Embodiment 2.

[0067] A driving assembly is installed inside the linear track 1.

[0068] A plurality of vehicle frames 7 are installed on the linear track 1 in a transmission manner through a driving assembly.

[0069] The material conveying line of this embodiment has the same beneficial effects as the above-mentioned stop structure, which will not be described in detail here.

[0070] Among them, the line track 1 is formed by overlapping a number of connecting wide frames 2 end to end. The specific structural form of the driving component is not limited, and various forms such as existing suspension chains and suspension warehouses are all acceptable. In this embodiment, preferably, the driving component includes a driving motor 3, a friction rod 5 and a number of driven wheel groups 6. The driving motor 3 is installed on the line track 1, and a multi-V belt pulley 4 is connected to the output end. The friction rod 5 is connected to the multi-V belt pulley 4 in a transmission manner. A number of driven wheel groups 6 are evenly distributed on the frame 7 and are matched with the friction rod 5 in a transmission manner. In actual use, the driving motor 3 drives the friction rod 5 to rotate via the multi-V belt pulley 4, thereby driving the driven wheel group 6 to drive the frame 7 to move straight, realizing the orderly operation of the line body and facilitating the orderly transportation of materials.

[0071] Based on this embodiment, the functions may be further extended, for example, a position sensor and a controller may be further included.

[0072] The position sensor is installed on the linear track 1 to detect the position of the frame 7.

[0073] The controller is electrically connected to the drive assembly, the position sensor and the telescopic cylinder 12 .

[0074] The controller is used to control the telescopic cylinder 12 to stop working and the driving component to stop working when the position sensor detects that the frame 7 exceeds the preset parking position.

[0075] It should be understood that the controller controls the drive assembly to perform the parking operation according to the instruction when parking is required. At this time, it is necessary to detect the position of the frame 7. If the frame 7 is no longer in a reasonable parking position, the drive assembly will be operated rashly, which will cause a collision between the stop assembly and the frame 7, affecting the normal operation of the conveyor line. Therefore, it is necessary to detect the position of the frame 7 in real time to determine whether the current position of the frame 7 meets the stopping conditions to prevent damage to the conveyor line.

[0076] Furthermore, a pressure sensor and an alarm may also be included.

[0077] The pressure sensor is arranged in the limiting portion 8 and is used to detect the impact force between the limiting portion 8 of the front frame 7 and the stopping portion 9 of the rear frame 7 when the front and rear frames 7 are in contact.

[0078] The siren is used to sound an alarm.

[0079] The controller is also used to: when the impact force detected by the pressure sensor is greater than a preset safety pressure, control the drive component to stop working and control the alarm to sound an alarm.

[0080] After the front frame 7 is stopped, the rear frame 7 will collide with the front frame 7 to stop the vehicle. However, the collision force during the collision cannot be controlled. If the collision force is too large, the frame 7 or the front stop member 11 may be deformed, and the position of the front stop member 11 may be changed. In this case, it is difficult to ensure that the front stop member 11 can still perform the subsequent stopping work. Therefore, the safety and the overall stability of the conveyor line can be improved by monitoring whether the impact force is greater than the preset safety pressure.

[0081] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
