Description

Technical Field

[0001] This utility model relates to the field of pallet limiting technology, and in particular to a pallet conveying limiting mechanism. Background Technology

[0002] In modern logistics and automated production, pallet conveyor systems are widely used in the transfer, sorting, and warehousing of goods. As a key component of the pallet conveyor system, the pallet conveyor limiting mechanism's main function is to precisely correct and limit the position of the pallet, ensuring that it accurately reaches the predetermined location during transport, facilitating subsequent loading, unloading, handling, and processing operations.

[0003] Existing pallet conveyor limiting mechanisms typically employ fixed-size limiting structures, directly correcting the position of misaligned pallets through rigid mechanical components. While this method can achieve pallet positioning to some extent, it has significant drawbacks. When the pallet misalignment is substantial, directly using a fixed limiting structure forcibly corrects it, causing the pallet to experience a large impact force upon contact with the limiting component. This can easily lead to the pallet getting stuck, affecting the normal operation of the conveyor system, reducing production efficiency, and potentially damaging both the pallet and the limiting mechanism itself, increasing equipment maintenance costs and downtime. Furthermore, fixed limiting structures cannot adapt to the conveying needs of pallets of different sizes, limiting the versatility and flexibility of the conveyor system.

[0004] Therefore, those skilled in the art have provided a pallet conveying limiting mechanism to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pallet conveying limiting mechanism that can progressively correct pallets to prevent jamming; it can flexibly adjust the limiting position to adapt to pallets of different specifications; it features automated control, efficient and precise correction, and improved conveying reliability and versatility.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pallet conveying limiting mechanism includes a conveyor belt, with adjustable limiting mechanisms fixedly installed on both sides of the conveyor belt, and a controller fixedly installed on one side of the conveyor belt.

[0008] The adjustable limiting mechanism includes a side connecting plate, which is fixedly installed on the side of the conveyor belt. A first hydraulic pipe, a second hydraulic pipe, and a third hydraulic pipe are installed through the side connecting plate. The initial lengths of the first hydraulic pipe, the second hydraulic pipe, and the third hydraulic pipe decrease sequentially. The end of the conveyor belt near the third hydraulic pipe is the pallet conveying inlet.

[0009] Furthermore, three straightening frames are hinged to the side connecting plate near the inner side of the conveyor belt, and a support spring is fixedly connected to one side of each of the three straightening frames and the side connecting plate.

[0010] Furthermore, each of the three correction frames has a correction plate fixedly installed at one end, and the three correction plates respectively contact one end of the first hydraulic pipe, the second hydraulic pipe and the third hydraulic pipe.

[0011] Furthermore, a storage box is fixedly installed on one side of the side connecting plate. The storage box contains hydraulic oil and an oil pump. A transmission pipe is fixedly installed at the output end of the oil pump. The transmission pipe is connected to the input ends of the first hydraulic pipe, the second hydraulic pipe, and the third hydraulic pipe, respectively.

[0012] Furthermore, a rubber pad is fixedly installed at one end of the first hydraulic pipe, the second hydraulic pipe, and the third hydraulic pipe, so that they can contact the straightening plate.

[0013] Furthermore, the controller is electrically connected to the oil pump inside the storage tank.

[0014] Furthermore, the elastic coefficient of the support spring is set according to the position and functional requirements of the corresponding correction frame. The elastic coefficient of the support spring near the pallet conveying inlet is greater than that of the support spring far from the inlet, so as to achieve progressive correction and limiting of the pallet.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a pallet conveying limiting mechanism. This mechanism, through the sequentially decreasing initial lengths of a first, second, and third hydraulic pipe, combined with a support spring and a straightening frame, achieves progressive straightening of the pallet. During conveying, the pallet passes through straightening plates at different positions for gradual straightening. The straightening force and range at each stage are rationally controlled, preventing the pallet from jamming due to forced straightening in one go, effectively improving the smoothness and reliability of pallet conveying.

[0017] 2. This utility model proposes a pallet conveying limiting mechanism. The adjustable limiting mechanism can control an oil pump to fill the hydraulic pipe via a controller, thereby adjusting the length of the hydraulic pipe and consequently adjusting the position of the straightening frame and straightening plate. This design allows the mechanism to adapt to the conveying needs of pallets of different sizes and specifications, and effectively corrects pallet misalignment to varying degrees. This greatly improves the versatility and flexibility of the pallet conveying limiting mechanism, and reduces the costs incurred by enterprises due to replacing pallet conveying equipment of different specifications.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-4 An embodiment of this utility model is provided: a pallet conveying limiting mechanism, including a conveyor belt 1, adjustable limiting mechanisms 2 are fixedly provided on both sides of the conveyor belt 1, and a controller 3 is fixedly provided on one side of the conveyor belt 1;

[0026] Specifically, the conveyor belt 1 serves as the basic component for pallet conveying. Its symmetrically arranged adjustable limiting mechanisms 2 can correct the position of the pallet from both sides, ensuring the stability and accuracy of the correction process. The controller 3 enables automated control of the entire limiting mechanism, improving correction efficiency and precision.

[0027] The adjustable limiting mechanism 2 includes a side connecting plate 201, which is fixedly installed on the side of the conveyor belt 1. A first hydraulic pipe 204, a second hydraulic pipe 207, and a third hydraulic pipe 208 are installed through the side connecting plate 201. The initial lengths of the first hydraulic pipe 204, the second hydraulic pipe 207, and the third hydraulic pipe 208 decrease sequentially. The end of the conveyor belt 1 closest to the third hydraulic pipe 208 is the pallet conveying inlet.

[0028] Specifically, by setting three hydraulic pipes with different initial lengths, a stepped correction position can be formed after oil filling. For example, the first hydraulic pipe 204 has an initial length of 300mm, the second hydraulic pipe 207 has an initial length of 250mm, and the third hydraulic pipe 208 has an initial length of 200mm. This design allows the pallet to pass through different correction positions sequentially during transportation, achieving gradual correction and effectively avoiding the problem of pallet jamming caused by excessive correction amplitude at one time.

[0029] Three straightening frames 206 are hinged to the side connecting plate 201 near the inner side of the conveyor belt 1. Each of the three straightening frames 206 is fixedly connected to the side connecting plate 201 on one side. Each of the three straightening frames 206 is fixedly provided with a straightening plate 205 at one end. The three straightening plates 205 respectively contact one end of the first hydraulic pipe 204, the second hydraulic pipe 207 and the third hydraulic pipe 208. The elastic coefficient of the support spring 210 is set according to the position and functional requirements of the corresponding straightening frame 206. The elastic coefficient of the support spring 210 near the pallet conveying inlet is greater than that of the support spring 210 far from the inlet, so as to realize the gradual correction and limiting of the pallet.

[0030] Specifically, the hinged design of the straightening frame 206 allows it to rotate flexibly under the actuation of the hydraulic pipe, thereby adjusting the position of the straightening plate 205. The spring constants of the support springs 210 are set in a gradient manner; for example, the spring constant is 10 N / mm at the inlet, 8 N / mm in the middle, and 5 N / mm at the outlet, providing different buffering forces according to the degree of pallet offset. When the pallet offset is large, the spring with the larger spring constant provides sufficient resistance to prevent excessive pallet offset; while during subsequent straightening, the spring with the smaller spring constant ensures that the pallet is smoothly straightened to the accurate position.

[0031] A storage box 202 is fixedly installed on one side of the side connecting plate 201. The storage box 202 contains hydraulic oil and an oil pump. The controller 3 is electrically connected to the oil pump in the storage box 202. A transmission pipe 203 is fixedly installed at the output end of the oil pump. The transmission pipe 203 is connected to the input ends of the first hydraulic pipe 204, the second hydraulic pipe 207 and the third hydraulic pipe 208 respectively. A rubber pad 209 is fixedly installed at one end of the first hydraulic pipe 204, the second hydraulic pipe 207 and the third hydraulic pipe 208, which can contact the straightening plate 205.

[0032] Specifically, the hydraulic system consisting of the storage tank 202 and the oil pump provides power for the extension and retraction of the hydraulic hose. The controller 3 precisely adjusts the extension length of the hydraulic hose by controlling the start and stop of the oil pump and the flow rate. The rubber pad 209 increases the friction between the hydraulic hose and the straightening plate 205, ensuring stable contact between the two, while also acting as a buffer to reduce the impact force during the straightening process and protect the equipment and the pallet.

[0033] Working principle: When this pallet conveying and limiting mechanism is working, the controller 3 first controls the oil pump in the storage tank 202 to start. The oil pump delivers the hydraulic oil in the storage tank 202 to the first hydraulic pipe 204, the second hydraulic pipe 207, and the third hydraulic pipe 208 through the transmission pipe 203. Since the initial lengths of the first hydraulic pipe 204, the second hydraulic pipe 207, and the third hydraulic pipe 208 decrease sequentially, after being filled with oil, all three hydraulic pipes will extend, but the extension lengths are different, thus causing the straightening plate 205, which is in contact with one end of the hydraulic pipe, to be in different positions.

[0034] When the pallet enters the conveyor system from the end of conveyor belt 1 near the third hydraulic pipe 208, it first contacts the straightening plate 205 near that end. At this point, under the action of the support spring 210, the straightening plate 205 applies a buffered straightening force to the pallet, causing initial straightening, with the final straightening limit being that the straightening plate 205 contacts the third hydraulic pipe 208. After initial straightening, the pallet continues to move along conveyor belt 1 and then contacts the second straightening plate 205. Under the action of the second straightening plate 205 and the corresponding support spring 210, the pallet is straightened again, further adjusting its position. Finally, the pallet moves to the third straightening plate 205, where the final straightening is completed, bringing the pallet to the predetermined conveying position, thus achieving progressive straightening and limiting of the pallet. Throughout the process, the elastic coefficient of the support spring 210 is set according to the position and functional requirements of the corresponding straightening frame 206. The support spring 210 near the pallet conveying inlet has a larger elastic coefficient, which can provide a larger buffer force when the pallet deviates significantly. As the pallet moves, the elastic coefficient of the subsequent support spring 210 gradually decreases, ensuring that the pallet can be gradually and smoothly straightened to the accurate position.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
