Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to a feed bag conveying buffer device and conveying system. Background Technology

[0002] In the feed processing industry, feed bales (hereinafter referred to as bales) undergo a packaging process and are then transported via a finished product conveyor line for automated palletizing before being shipped out. To achieve this process, the inclined conveyor is one of the key pieces of equipment on the finished product conveyor line, used to smoothly transport bales from a higher to a lower position. However, due to space constraints in some factory layouts, packaging machines are often located at higher positions. To transport bales from these higher positions to the inclined conveyor within a limited space and to avoid using excessively long and space-consuming inclined conveyors, existing technologies often connect a steep chute with a large inclination angle above the receiving end of the inclined conveyor. The bales first slide from the discharge conveyor line of the higher-level packaging machine into this chute, then descend under gravity into the inclined conveyor, thus shortening the path to the inclined conveyor.

[0003] While this chute structure solves the space efficiency problem of high-position bag dropping, the bags accelerate downwards in the chute, gaining a large initial velocity before directly plunging into the relatively gentle inclined conveyor. Since the conveyor belt width of the inclined conveyor is usually larger than the bag width (to accommodate different bag sizes and allow for some deviation), the high-speed plunging bags are prone to excessive slippage and deviation on the conveyor belt due to inertia, failing to stably follow the predetermined center trajectory. This deviation has significant consequences for subsequent automated palletizing processes. The gripping coordinates of the palletizing robot are usually pre-set and fixed. Although it has a certain tolerance to adapt to positional changes within a range, when the slippage distance caused by the initial impact of the bag is too large, deviating from the predetermined trajectory beyond the robot's tolerance range, it will lead to gripping failure or inaccurate positioning. The robot's gripping teeth may also damage the packaging bag during the gripping process, affecting product quality, causing losses, and reducing palletizing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a feed bag conveying buffer device and conveying system, which can buffer the feed bags that slide down rapidly from the chute, reduce the slippage and deflection of the bags due to inertia, reduce the damage rate of the packaging bags in the subsequent gripping and palletizing process, and improve the overall conveying and palletizing efficiency and stability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a feed bag conveying buffer device, disposed above the receiving end of an inclined conveyor, comprising: The gantry frame is installed across the width of the inclined conveyor. A crossbar is rotatably connected between two columns of the gantry frame; A buffer roller unit includes a mounting frame and a buffer roller. The mounting frame is fixedly connected to a crossbar and can rotate synchronously with it. The buffer roller is rotatably mounted on the mounting frame. Pull-out constraint, connected between the mounting frame and the gantry frame, is used to limit the lowest position of the buffer roller; The buffer roller unit relies on its own weight to keep the buffer roller in the lowest working position when it is not impacted. When the feed bag impacts the buffer roller, the buffer roller can rotate and drive the mounting frame to rotate upward around the crossbar to buffer the impact force. After the impact, it relies on its own weight to reposition to the lowest position.

[0006] A further improvement of this utility model is that the gantry frame is provided with an adjustment component, the adjustment component includes a connector disposed on the material receiving side of the gantry frame, the connector is provided with a screw hole and an adjustment screw is threadedly connected thereto, and the lower end of the adjustment screw is fixedly connected to the pulling constraint component.

[0007] A further improvement of this utility model is that locking nuts are provided on both the upper and lower parts of the adjusting screw and the connecting member.

[0008] A further improvement of this invention is that the surface of the buffer roller is covered with a buffer layer.

[0009] A further improvement of this utility model is that the pulling constraint component is a chain or a steel wire rope.

[0010] This utility model also discloses a conveying system, including an inclined conveyor and a chute for conveying materials thereto. A buffer device as described above is provided above the receiving end of the inclined conveyor, and a flow guiding mechanism is provided at the outlet end of the chute, which includes two symmetrically arranged and angle-adjustable guide plates for constraining the sliding trajectory of the feed bag.

[0011] A further improvement of this utility model is that the guide plate is disposed on the inner wall of the slide groove at the end of the slide groove, the upstream end of the guide plate is hinged to the slide groove, and the opposing sides of the two guide plates are provided with a driving member to control their rotation angle.

[0012] A further improvement of this utility model is that the driving component includes cylinders disposed on both sides of the slide groove, the telescopic ends of the cylinders passing through the groove wall of the slide groove and abutting against the back of the guide plate.

[0013] A further improvement of this utility model is that the front and rear ends of the guide plate are chamfered.

[0014] The beneficial effects of this utility model are as follows: This invention effectively buffers the enormous impact force of material bags rushing at high speed from steep chutes into inclined conveyors without significantly altering the existing factory layout and conveyor line structure. It suppresses excessive slippage and trajectory deviation on the conveyor belt, ensuring that the material bags can stably enter the subsequent conveying and palletizing stages. This reduces the problem of gripping failure and bag breakage caused by excessive positional deviation during subsequent gripping and palletizing, thereby reducing the breakage rate of feed bags and improving the overall efficiency and stability of conveying and palletizing.

[0015] This invention features a rotatable buffer roller unit and a tension constraint component. When the feed bag is impacted, the buffer roller can rotate upward to absorb the impact force, reducing the slippage and deviation of the feed bag on the inclined conveyor. After the impact, it relies on self-realignment. The structure is simple and reliable, requires no external power, and effectively improves the stability of feed bag conveying.

[0016] This invention allows for flexible adjustment of the length of the pulling constraint component through an adjustable assembly, thereby controlling the lowest position of the buffer roller. This enables the device to adapt to feed bags of different sizes, enhancing the versatility of the device and the adjustability of the buffering effect, and improving the adaptability of the device.

[0017] When the buffer roller of this invention is impacted and rotates upward, its rolling contact can squeeze the feed bag and apply rolling pressure to the surface of the feed bag. This helps to expel some of the air inside the packaging bag, making the bulging packaging bag flatter and reducing the bag's bulkiness, which is convenient for subsequent stacking.

[0018] This utility model provides a conveying system that combines a buffer device with a chute guide mechanism. The buffer device reduces the impact force on the feed bag, while the guide mechanism constrains the sliding trajectory of the feed bag. The two work together to ensure that the feed bag smoothly transitions from the chute to the inclined conveyor, further reducing the slippage and deviation of the feed bag.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. Example 1

[0027] Combination Figure 1-4 It is known that a feed bag conveying buffer device, installed above the receiving end of the inclined conveyor 1, includes: Gantry 2 is set across the width of inclined conveyor 1; The crossbar 3 is rotatably connected between the two columns of the gantry frame 2; The buffer roller unit includes a mounting frame 4 and a buffer roller 5. The mounting frame 4 is fixedly connected to the crossbar 3 and can rotate synchronously with it. The buffer roller 5 is rotatably mounted on the mounting frame 4. Pull constraint 6, connected between mounting frame 4 and gantry 2, is used to limit the lowest position of buffer roller 5; When the buffer roller unit is not impacted, it relies on its own weight to keep the buffer roller 5 in the lowest working position. When the feed bag impacts the buffer roller 5, the buffer roller 5 can rotate and drive the mounting frame 4 to rotate upward around the crossbar 3 to buffer the impact force. After the impact, it relies on its own weight to reposition to the lowest position.

[0028] The gantry 2 is equipped with an adjustment assembly, which includes a connector 7 located on the material receiving side of the gantry 2 (i.e., the side near the outlet of the chute 10). The connector 7 has a screw hole and is threadedly connected to an adjustment screw 8. The lower end of the adjustment screw 8 is fixedly connected to the pulling constraint 6.

[0029] Preferably, the mounting frame 4 includes two symmetrically arranged frame arms, a buffer roller 5 is rotatably connected between the two frame arms, one end of the frame arm is fixedly connected to the crossbar 3, a crossbeam is provided between the two frame arms, one end of the pulling constraint member 6 is fixedly connected to the crossbeam, and the other end is fixedly connected to the adjusting screw 8.

[0030] Locking nuts 9 are provided on both the upper and lower parts of the adjusting screw 8 and the connecting part 7. After adjustment, tighten the two locking nuts 9 to lock the adjusting screw 8 and the connecting part 7 in place and prevent them from loosening. By setting the locking nuts 9, the position of the adjusting screw can be fixed, preventing loosening due to vibration or impact during equipment operation, ensuring the stability and reliability of the position of the buffer roller 5, and improving the safety and service life of the device.

[0031] Preferably, the surface of the buffer roller 5 is covered with a buffer layer. The buffer layer can be made of a material with certain elasticity and wear resistance, such as rubber, polyurethane, or polymer composite materials, and its thickness can be selected according to the buffering requirements, for example, 5-20mm. The buffer layer enhances the buffering effect, absorbs impact energy through soft materials, reduces direct hard impact on the feed bag, prevents the feed bag from breaking during the buffering process, and also reduces noise and wear.

[0032] Preferably, the tension restraint 6 is a chain or wire rope. One end is fixed to the mounting frame 4 via a connecting ring or pin, and the other end is fixedly connected to the adjusting screw 8. This reliably limits the lowest position of the buffer roller 5 while allowing the buffer roller 5 to rotate freely during impact, ensuring the durability and stability of the device. Example 2

[0033] This embodiment also discloses a conveying system, including an inclined conveyor 1 and a chute 10 for conveying materials thereto. A buffer device as shown in Embodiment 1 is provided above the receiving end of the inclined conveyor 1. The outlet end of the chute 10 is provided with a guide mechanism, which includes two symmetrically arranged and angle-adjustable guide plates 11 for constraining the sliding trajectory of the feed bag. The inclined conveyor 1 is a conventional device in the prior art, and its conveyor belt has side plates on both sides.

[0034] Guide plates 11 are mounted on the inner wall of the chute 10 at its end. The upstream end of the guide plates 11 is hinged to the chute 10. The opposing sides of the two guide plates 11 are equipped with driving components to control their rotation angle. This system can control the sliding direction and landing point of the feed bag, adapting to different feed bag sizes or conveying conditions, enhancing the flexibility and controllability of the system, and further reducing trajectory deviation and impact.

[0035] Preferably, the driving component includes cylinders 12 disposed on both sides of the chute 10, with the telescopic ends of the cylinders 12 passing through the chute wall of the chute 10 and abutting against the back of the guide plate 11. This allows for the adaptation of feed bags of different sizes to be conveyed by adjusting the angle of the guide plate.

[0036] Preferably, the side wall of the chute 10 is provided with a receiving port, and a rotating shaft is rotatably provided inside the receiving port. One end of the guide plate 11 is rotatably connected to the rotating shaft. The cylinder body of the cylinder 12 is fixedly installed on the bracket outside the chute 10. By controlling the extension or retraction length of the telescopic rod of the cylinder 12, the guide plate 11 can be pushed to rotate around its hinge point, thereby adjusting the included angle between the two guide plates 11 (i.e. the width and guiding angle of the guide channel). The angle of the guide plate 11 can be adjusted to adapt to the conveying of feed bags of different specifications.

[0037] Preferably, the guide plate 11 has chamfers at both ends along the chute direction. This reduces frictional resistance and jamming when the feed bag contacts the guide plate 11, allowing the feed bag to transition smoothly and avoiding damage to the packaging.

[0038] Other structures are conventional structures in this field and will not be described in detail here.

[0039] The working principle of the feed bag conveying buffer device provided by the utility model is as follows: As the feed bag accelerates down the high-level chute 10, its sliding trajectory is first constrained by two adjustable guide plates 11 of the guiding mechanism, causing it to align with the buffer roller 5. The feed bag impacts the buffer roller 5 at a relatively high speed along the trajectory. Under the impact force, the buffer roller 5 rotates upward, driving the mounting frame 4 to rotate around the crossbar 3, thereby absorbing the kinetic energy of the feed bag, buffering the impact force, and reducing the speed and inertia of the feed bag when it falls into the inclined conveyor 1. After the impact, the buffer roller 5 returns to its lowest position by its own weight and the restraint of the pulling constraint 6. At this time, the feed bag has landed smoothly on the conveyor belt of the inclined conveyor 1 and runs along the predetermined trajectory to the stacking station, avoiding excessive deviation that could lead to gripping failure or packaging damage.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
