Description

Technical Field

[0001] This utility model relates to the field of long strip product conveying technology, specifically to an automatic conveying device for long pallets. Background Technology

[0002] In modern manufacturing, the handling of long and narrow products has become one of the major bottlenecks restricting production efficiency and smooth logistics. After their manufacturing is completed, long and narrow items must undergo a series of handling operations to move from one processing point to another, or from the production line to the storage area, and may even need to be transferred across factories or regions.

[0003] However, due to their significant length—the length far exceeding the width and height ratio—long, rectangular items present numerous challenges during handling. Their geometry makes them difficult to stabilize during transport; without proper support, they are prone to bending, tilting, or even accidental drops, increasing operational risks, product quality, and defect rates. Traditional handling methods largely rely on manpower or simple mechanical aids like handcarts. However, using handcarts to move long, rectangular items requires multiple people to ensure stability, and the difficulty increases significantly when turning or navigating narrow passages, increasing the risk of collisions. The physical exertion on workers is also considerable; prolonged work can lead to fatigue, reducing efficiency and safety. To ensure safety and accuracy during handling, it is often necessary to employ teams of two or more people, requiring substantial manpower. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide an automatic conveying device for long pallets, which solves the technical problems of poor stability and time-consuming and labor-intensive processes in the handling of long and strip-shaped products.

[0005] To achieve the above-mentioned technical objectives, the present invention provides an automatic long pallet conveying device, comprising:

[0006] The system includes a servo drive mechanism, a support and guide mechanism, and a pin-clutch mechanism. The servo drive mechanism comprises a servo drive source, a first rotating body, and a second rotating body. The output shaft of the servo drive source is drivenly connected to the first rotating body. The first rotating body is drivenly connected to the second rotating body via a synchronous belt, which covers the outer peripheral walls of both the first and second rotating bodies. The support and guide mechanism includes a first support mounting plate, a second support mounting plate, a first guide mounting plate, and a second guide mounting plate. The cross-sections of the first and second support mounting plates are U-shaped. The bottom end of the first support mounting plate is fixedly connected to the output end face of the servo drive source, and the second rotating body is rotatably connected to the second support mounting plate.

[0007] Compared with the prior art, the beneficial effects of this utility model include:

[0008] 1. Saves time and effort: The automatic long pallet conveying device provided by this utility model improves the efficiency of handling long and narrow products by utilizing a support and guiding mechanism.

[0009] 2. High stability: The long pallet automatic conveying device provided by this utility model uses a servo transmission mechanism and a pin clutch mechanism to solve the problem that due to the geometric characteristics of long and strip-shaped items (length far exceeds width and height), it is difficult to maintain stability during handling, which increases the risk of operation and easily leads to items bending, tilting or falling, which may damage product quality and increase the defect rate.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This embodiment provides an automatic long pallet conveying device, including: a servo transmission mechanism 1, a support and guide mechanism 2, and a pin clutch mechanism 3.

[0019] Furthermore, the servo transmission mechanism 1 includes a servo drive source 11, a first rotating body 12, and a second rotating body 13. The output shaft of the servo drive source 11 is drivenly connected to the first rotating body 12, and the first rotating body 12 is drivenly connected to the second rotating body 13 via a synchronous belt 14, which covers the outer peripheral walls of the first rotating body 12 and the second rotating body 13.

[0020] Preferably, the servo drive source 11 is a servo motor. In this embodiment, the servo motor has the following advantages: 1. High-precision positioning: Servo motors can provide very high position control accuracy, which is crucial for conveyor systems that require precise movement or stopping. For example, in assembly lines, packaging machines, and material handling systems, it ensures that products are accurately placed or handled; 2. Fast response: Servo motors have rapid acceleration and deceleration capabilities, and can reach the required speed or stop in a short time. This allows the conveyor belt to quickly adjust its speed to adapt to different production needs or emergencies; 3. Strong programmability: Through an integrated controller or PLC (Programmable Logic Controller), users can easily program and adjust the working mode of the servo motor according to specific application requirements. This means that the same conveyor system can be adapted to a variety of different tasks through simple software changes.

[0021] Furthermore, the rotation of the output shaft of the servo drive source 11 drives the first rotating body 12 to rotate, and under the action of the synchronous belt 14, the rotation of the first rotating body 12 drives the rotation of the second rotating body 13.

[0022] Furthermore, the outer peripheral walls of the first rotating body 12 and the second rotating body 13 are provided with driving teeth, and the inner side of the synchronous belt 14 is provided with a driving groove, and the driving teeth are placed in the driving groove.

[0023] Furthermore, the action of the drive groove and the drive teeth can effectively prevent the first rotating body 12 and the second rotating body 13 from slipping, ensuring a slip-free transmission between the first rotating body 12 and the second rotating body 13, thereby achieving highly accurate speed ratio and position control, reducing energy loss, and improving transmission efficiency.

[0024] Preferably, in this embodiment, both the first rotating body 12 and the second rotating body 13 are selected as gears.

[0025] Furthermore, the support and guide mechanism 2 includes a first support mounting plate 21, a second support mounting plate 22, a first guide mounting plate 23, and a second guide mounting plate 24. The first support mounting plate 21 and the second support mounting plate 22 have U-shaped cross-sections. The bottom end of the first support mounting plate 21 is fixedly connected to the output end face of the servo drive source 11, and the second rotating body 13 is rotatably connected to the second support mounting plate 22.

[0026] Specifically, the bottom end of the second support mounting plate 22 is provided with a through hole, and the inner ring of the second rotating body 13 is equipped with a bearing. The inner ring of the bearing is detachably fixed to the second support mounting plate 22 by bolts passing through the through hole of the second support mounting plate 22.

[0027] Furthermore, the first support mounting plate 21 is fixedly connected to the second support mounting plate 22 via the first guide mounting plate 23. One end of the first guide mounting plate 23 is fixedly connected to the top surface of the first support mounting plate 21, and the other end of the first guide mounting plate 23 is fixedly connected to the top surface of the second support mounting plate 22. Two first guide mounting plates 23 are provided on both sides of the top of the first support mounting plate 21 and the second support mounting plate 22.

[0028] Furthermore, the second guide mounting plate 24 and the first guide mounting plate 23 are arranged perpendicular to each other, and the upper end surface of the first guide mounting plate 23 is fixedly connected to the second guide mounting plate 24. Limiting steps 241 are opened on the inner side of the two second guide mounting plates 24.

[0029] Furthermore, a first guide wheel 25 is rotatably connected to the inner side of the first guide mounting plate 23. The distance between the axis of the first guide wheel 25 and the limiting step 241 is less than the outer diameter of the first guide wheel 25. The two end faces of the first guide wheel 25 are arranged perpendicular to the horizontal plane.

[0030] Furthermore, a second guide wheel 26 is rotatably connected to the end face of the first guide mounting plate 23. The distance between the axis of the second guide wheel 26 and the limiting step 241 is less than the outer diameter of the second guide wheel 26. The two end faces of the second guide wheel 26 are arranged horizontally with the horizontal plane. Furthermore, the first guide wheel 25 and the second guide wheel 26 are arranged in an array along the length direction of the first guide mounting plate 23.

[0031] Specifically, when the elongated item 4 is placed on the limiting steps 241 of the two first guide mounting plates 23, the outer wall of the first guide wheel 25 is in close contact with the bottom surface of the elongated item 4, there is a gap between the step surface of the limiting step 241 and the bottom surface of the elongated item 4, and the outer wall of the second guide wheel 26 is in close contact with the side of the elongated item 4, so that there is a gap between the side of the elongated item 4 and the first guide mounting plate 23, allowing the elongated item 4 to slide on the support guide mechanism 2, reducing the friction between the two and facilitating the transportation of the elongated item 4.

[0032] Preferably, both the first guide wheel 25 and the second guide wheel 26 are made of bearings. In this embodiment, the first guide wheel 25 and the second guide wheel 26 serve to guide and reduce friction.

[0033] Furthermore, the pin-clutch mechanism 3 includes a linear guide rail 31, a movable slider 32, a pressure plate 33, a clutch support plate 34, and a pin 35. The lower end of the clutch support plate 34 is fixedly connected to the pressure plate 33, and the pressure plate 33 is fixedly connected to the synchronous belt 14. The upper end of the clutch support plate 34 is provided with a clutch drive source 36 and a support block 37, and the upper end of the support block 37 is fixedly connected to the movable slider 32.

[0034] Furthermore, the linear guide rail 31 is fixedly connected to the lower end face of the first guide mounting plate 23, the movable slider 32 is slidably connected to the linear guide rail 31, and the output shaft of the clutch drive source 36 is fixedly connected to the pin 35 through the connecting plate 38.

[0035] Furthermore, each of the first guide mounting plates 23 is provided with the pin clutch mechanism 3 at its lower end, and a plurality of second guide mounting plates 24 are arranged in an array along the length direction on the upper end surface of the first guide mounting plate 23. Reinforcing plates 27 are also welded and fixed to the two ends of the two oppositely arranged first guide mounting plates 23 to reinforce the stability of the device.

[0036] Specifically, the elongated item 4 has a through hole running vertically through it. When the elongated item 4 needs to be transported, the clutch drive source 36 located on both sides of the first guide mounting plate 23 operates, causing the output shaft of the clutch drive source 36 to extend, thereby causing the pin 35 to move upward and insert into the through hole of the elongated item 4. At this time, the servo drive source 11 operates, thereby driving the synchronous belt 14 to rotate. Since the pin clutch mechanism 3 is fixedly connected to the synchronous belt 14 through the clamping plate 33, when the synchronous belt 14 is rotating, the pin clutch mechanism 3 is driven to move along the linear guide rail, thereby driving the elongated item 4 to move along the length direction of the first guide mounting plate 23.

[0037] When the transport route of the long strip item 4 is long, multiple devices need to be spliced ​​together along the transport route of the long strip item 4.

[0038] Preferably, in this embodiment, the clutch drive source 36 is a pneumatic drive source, which has the following advantages: 1. High safety: When the load exceeds the system's capacity, the pneumatic system can avoid damage by releasing excess gas, providing natural overload protection; 2. Fast response: Pneumatic actuators can achieve very fast speed changes, from standstill to full speed in just a few milliseconds; 3. Pneumatic components are small in size and light in weight, making them easy to integrate into compact designs.

[0039] Working Principle: The automatic long pallet conveying device provided by this utility model includes a servo transmission mechanism 1, a support and guide mechanism 2, and a pin-clutch mechanism 3. The servo transmission mechanism 1 includes a servo drive source 11, a first rotating body 12, and a second rotating body 13. The output shaft of the servo drive source 11 is drivenly connected to the first rotating body 12, and the first rotating body 12 is drivenly connected to the second rotating body 13 via a synchronous belt 14, which covers the outer peripheral walls of the first rotating body 12 and the second rotating body 13. Further, the support and guide mechanism 2 includes a first support mounting plate 21, a second support mounting plate 22, a first guide mounting plate 23, and a second guide mounting plate 24. The cross-sections of the first support mounting plate 21 and the second support mounting plate 22 are U-shaped. The bottom end of the first support mounting plate 21 is fixedly connected to the output end face of the servo drive source 11, and the second rotating body 13 is rotatably connected to the second support mounting plate 22.

[0040] Specifically, when the long strip-shaped item 4 needs to be transported, the clutch drive source 36 located on both sides of the first guide mounting plate 23 operates, causing the output shaft of the clutch drive source 36 to extend, thereby causing the pin 35 to move upward and insert into the through hole of the long strip-shaped item 4. At this time, the servo drive source 11 operates, thereby driving the synchronous belt 14 to rotate. Since the pin clutch mechanism 3 is fixedly connected to the synchronous belt 14 through the clamping plate 33, when the synchronous belt 14 is rotating, the pin clutch mechanism 3 is driven to move along the linear guide rail, thereby driving the long strip-shaped item 4 to move along the length direction of the first guide mounting plate 23.
