Description

Technical Field

[0001] This invention belongs to the field of conveying, palletizing, loading and logistics machinery, and in particular relates to a high-efficiency fully automatic multi-grip loader. Background Technology

[0002] In various chemical, grain and oil, food, light industry, and pharmaceutical production enterprises, manual loading or manual loading assisted by equipment is currently the most common method. This method has a long work cycle, requires a large number of personnel rotations, and is labor-intensive, inefficient, and the harsh working environment causes certain damage to the health of operators. Moreover, there are currently few young people engaged in loading and unloading work; most are middle-aged and elderly laborers around fifty years old, and the shortage of loading and unloading personnel will become increasingly severe over time. Furthermore, with the development of the automation industry, the loading requirements of various manufacturers per unit hour have increased. In order to better adapt to and serve the entire automated loading industry, there is an urgent need to invent a more automated and efficient loading equipment. Summary of the Invention

[0003] In view of this, in order to solve the technical problems mentioned in the background art, the present invention proposes a high-efficiency fully automatic multi-grip loader. The loader can automatically load bags into high-sided trucks, low-sided trucks and flatbed trucks through the different functions of its component design. The entire loading process only requires personnel to input simple vehicle data, and the rest can be fully automated.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency fully automatic multi-grip loader, comprising a mobile conveying unit, a lane-splitting unit, a grouping unit, and a loading unit, wherein the mobile conveying unit, the lane-splitting unit, and the grouping unit are connected in sequence, and the grouping unit is hung upside down on the loading unit;

[0005] The mobile conveying unit includes belt conveyor I, belt conveyor II, rail-mounted mobile vehicle, first traveling track, and belt conveyor III. Belt conveyor I, belt conveyor II, and belt conveyor III are connected in sequence, and the first traveling track is fixed on the loading platform.

[0006] The lane separation unit includes a lane separation conveyor and several inclined conveyors. The lane separation conveyor is connected to several inclined conveyors and is connected to a rail-mounted vehicle.

[0007] The grouping unit includes several square roller conveyors and several grouping conveyors. The square roller conveyors and grouping conveyors are connected and suspended together on the upper lifting frame of the loading unit. The square roller conveyors are correspondingly connected to several inclined conveyors. The inclined conveyors are connected to the grouping unit. This connection is not rigid, but rather the inclined conveyors are connected to the square roller conveyors by separate displacement mechanisms. The purpose of this is because the moving conveyor unit and the loading unit have independent travel power. In order to avoid the problem of local stress concentration in the entire loader when there is a slight deviation in the travel speed between the moving conveyor unit and the loading unit, laser distance detection, optical switches and other components are designed on the square roller conveyors to ensure that the relative position between the moving conveyor unit and the loading unit is kept within a certain deviation range. When the relative distance is closer, the travel speed of the moving conveyor unit is slower, and vice versa.

[0008] The loading unit includes a traveling trolley, a second traveling track, an overall lifting mechanism, a lifting frame, a Y-axis track moving car, a Z-axis lifting machine, an X-axis side adjustment mechanism, and a loading grabber. The traveling trolley provides power for the overall lifting mechanism, the lifting frame, the Y-axis track moving car, the Z-axis lifting machine, the X-axis side adjustment mechanism, the loading grabber, and the marshalling unit to move along the second traveling track for loading operations. The Y-axis track moving car, the Z-axis lifting machine, and the X-axis side adjustment mechanism are mounted on the lifting frame, forming a three-dimensional moving structure. The loading grabber is connected below the Z-axis lifting machine, and uses its own opening and closing mechanism to grab the material bags above the marshalling unit and place them into the car body.

[0009] The overall lifting mechanism is connected to the traveling trolley and the lifting frame, driving the lifting frame, the Y-axis track moving car, the Z-axis lifting machine, the X-axis side adjustment mechanism, and the grouping unit to rise and fall together.

[0010] Furthermore, the separate conveyor is connected to the rail-mounted mobile vehicle via a pivot.

[0011] Furthermore, the inclined conveyor is connected to the square roller conveyor via a rotary shaft.

[0012] Furthermore, the traveling trolley is powered by an electric motor, and its steel frame welded structure supports the loading unit and the train unit as they travel together.

[0013] Furthermore, the second traveling track is fixed to the loading platform and provides support for the entire loading unit to travel along it.

[0014] Furthermore, the Z-axis lifting platform is equipped with a rotating mechanism that can drive the loading grabber to rotate.

[0015] Compared with existing technologies, the advantages of the high-efficiency fully automatic multi-grip loader described in this invention are:

[0016] (1) Compared with traditional fully automatic loaders, the high-efficiency fully automatic multi-grip loader described in this invention has a significantly improved loading capacity, from the original 1000 bags / h to 1800-2200 bags / h.

[0017] (2) The present invention adds a grouping conveyor line. Traditional fully automatic loaders are single-line, single-side supply of material bags. The front end of the present invention is also a conveyor line to supply material bags. Then, the dividing unit conveys the material bags to the grouping units on both sides of the car body. In this way, the loading hand grabs the material bags from both sides to carry out the loading operation.

[0018] (3) The loading unit of the high-efficiency fully automatic multi-grip loader described in this invention is equipped with an overall lifting mechanism, which allows the invention to adjust the height of the entire loading unit in real time according to the height of the loading compartment and the height of the top loading bag during the loading operation, so as to ensure that the Z-axis travel of the lifting machine is minimized during the loading process, thereby improving the loading efficiency.

[0019] (4) The present invention adopts an X-axis side adjustment mechanism, which allows the present invention to adjust the center distance of each side adjustment mechanism according to different bag sizes, thereby overcoming the industry problem that a single model can be used for multiple sizes of bags at the same time. At the same time, after scanning the outline of the carriage by visual recognition, the most suitable arrangement of the bags in the carriage will be automatically calculated. Due to the diversity of bag sizes, there may be a situation where horizontal and vertical bags are placed alternately. At this time, the X-axis side adjustment mechanism can play a role in adjusting the center distance of each side adjustment mechanism in real time (that is, the center distance of the bag placement). The ability to load the same bag horizontally and vertically is also a prominent feature of this invention as a highly efficient fully automatic multi-grip loader.

[0020] (5) This invention belongs to a high-efficiency, multi-functional, fully automated loading equipment. It can accommodate a variety of vehicle types, including high-sided trucks, low-sided trucks, and flatbed trucks. At the same time, this invention is equipped with a vision recognition system. By scanning the outline of the truck body through the vision recognition system, the loading equipment can automatically calculate the loading group and loading quantity. Moreover, when loading high-sided trucks, the loading operation can be carried out without removing the top bracing. The main features are fully automated operation, clear equipment composition, high efficiency, flexible operation, cost saving, and multi-functionality.

[0021] (6) The high-efficiency fully automatic multi-grip loader described in this invention breaks away from the previous fully automatic loader concept. Traditional loader equipment feeds material from one side, so the loading hand can only grab the material bag from one side for loading, which affects loading efficiency and also leads to the monotony of loading methods.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0030] See Figures 1-5 This embodiment describes a high-efficiency fully automatic multi-grip loader, which includes a mobile conveying unit 1, a lane-splitting unit 2, a grouping unit 3, and a loading unit 4. The mobile conveying unit 1, the lane-splitting unit 2, and the grouping unit 3 are connected in sequence. The grouping unit 3 is hung upside down on the loading unit 4, and the loading unit 4 drives the grouping unit 3 to rise and fall together.

[0031] The mobile conveying unit 1 includes belt conveyor I11, belt conveyor II12, rail mobile vehicle 13, first traveling track 14, and belt conveyor III15. The belt conveyors I11, II12, and III15 are connected in sequence, and the first traveling track 14 is fixed on the loading platform.

[0032] The function of the mobile conveying unit 1 is to move together with the loading unit 4 and continuously supply the material bags, so as to achieve the effect of loading the material bags from the front of the vehicle to the rear of the vehicle.

[0033] The function of the belt conveyor I11 is to pre-group the bags. The belt conveyor I11 is designed with a flapping baffle mechanism, which is mainly to solve the problem of unevenness in the bags coming from the front end, with varying distances between them. The flapping baffle mechanism on the belt conveyor I11 is combined with the slow stop function of the belt conveyor II12 to make the spacing between the bags reach the preset form to meet the loading requirements.

[0034] The belt conveyor II12 is designed for slowing down the material bags.

[0035] The track-mounted mobile vehicle 13 carries and provides power. The mobile conveying unit 1 and the loading unit 4 are powered independently. The track-mounted mobile vehicle 13 mainly provides power to the mobile conveying unit, and the lane-sharing unit 2 is connected to the mobile conveying unit 1, which also indirectly provides power to the lane-sharing unit 2. The track-mounted mobile vehicle 13 moves together with the loading unit 4 to continuously supply material bags, thereby achieving the effect of loading material bags from the front of the vehicle to the rear of the vehicle.

[0036] The first traveling track 14 (which is the same track as the loading unit 4) is fixed on the loading platform and provides support for the entire loading unit to travel along it.

[0037] The belt conveyor III15 is quite long, so that material bags can fall onto its body during the loading process from the front to the rear of the vehicle.

[0038] The lane-splitting unit 2 mainly consists of a lane-splitting conveyor 21, an inclined conveyor I22, and an inclined conveyor II23. The lane-splitting conveyor 21 is connected to the two inclined conveyors via a frame to ensure accurate relative positions. The lane-splitting conveyor 21 of lane-splitting unit 2 is pivotally connected to the track-mounted vehicle 13 of the mobile conveyor unit 1, and the inclined conveyors are also pivotally connected to the square roller conveyor of the lower marshalling unit 3. This connection allows the lane-splitting unit to automatically change its tilt angle when adjusting the height of the loading unit during loading operations. The main function of lane-splitting unit 2 is to divide the bags from one conveyor line into two separate conveyor lines according to a pre-planned schedule.

[0039] The function of the split conveyor 21 is to connect with the mobile conveyor unit 1 and to realize the conveying of materials to the two inclined conveyors below according to the pre-designed grouping through the motor-driven guide mechanism.

[0040] The inclined conveyor connects to the lower grouping unit 3 and provides material bags to the grouping unit.

[0041] The grouping unit 3 includes several square roller conveyors and several grouping conveyors. The square roller conveyors and grouping conveyors are connected. The square roller conveyors are correspondingly connected to several inclined conveyors. This connection is not rigid, but rather the inclined conveyors are connected to the square roller conveyors by separate displacement mechanisms. This is done because the moving conveyor unit and the loading unit have separate travel power. To prevent local stress concentration in the entire loader when there is a slight deviation in the travel speed between the moving conveyor unit and the loading unit, laser distance detection, optical switches, and other components are designed on the square roller conveyors to ensure that the relative position between the moving conveyor unit and the loading unit is within a certain deviation range. When the relative distance is closer, the travel speed of the moving conveyor unit slows down, and vice versa.

[0042] The grouping unit 3 is connected to the lifting frame 44 of the upper loading unit 4 and the inclined conveyor of the channel unit 2. The grouping unit 3 consists of square roller conveyor I31, grouping conveyor I32, square roller conveyor II33, and grouping conveyor II34. Square roller conveyor I31 and square roller conveyor II33 are connected to inclined conveyor I22 and inclined conveyor II23, respectively. Their main function is to flatten and shape the bags that have changed posture after being conveyed by the inclined conveyor, so as to ensure that the posture of the bags is as uniform and flat as possible before loading, and to ensure that the stacking shape is as perfect as possible. The loading grabber 48 grabs the bags above the grouping unit 3.

[0043] The grouping conveyors I32 and II33 also have the effect of flattening the bags, but their main function is to allow the loading grabber 48 to grab the bags from above. The center distance of the bags on the grouping conveyors corresponds to the adjustment mechanism 47 on the x-axis side. If the grouping form changes, the adjustment center distance on the x-axis side will also change, and the center distance of the bags on the grouping machine will also change. The grouping machine consists of three sections and has a separate conveying power. The center distance of the bags on the grouping machine can be adjusted by the slow stop function of each section.

[0044] The loading unit 4 includes a traveling trolley 41, a second traveling track 42 (the second traveling track 42 is the same track as the first traveling track 14 in the mobile conveying unit), an overall lifting mechanism 43, a lifting frame 44, a Y-axis track moving vehicle 45, a Z-axis lifting machine 46, an X-axis side adjustment mechanism 47, and a loading grabber 48. The traveling trolley 41 provides power for the overall lifting mechanism 43, the lifting frame 44, the Y-axis track moving vehicle 45, the Z-axis lifting machine 46, the X-axis side adjustment mechanism 47, the loading grabber 48, and the grouping unit 3 to move along the second traveling track 42 for loading operations. Its main function is to grab the bags above the grouping unit 3 and load the bags into the carriage according to the pre-calculated and designed grouping. The Y-axis track moving vehicle 45, Z-axis lifting platform 46, and X-axis side adjustment mechanism 47 are installed on the lifting frame 44. The Y-axis track moving vehicle 45, Z-axis lifting platform 46, and X-axis side adjustment mechanism 47 form a three-dimensional moving structure. The loading grabber 48 is connected below the Z-axis lifting platform 46. The loading grabber 48 uses its own opening and closing mechanism to grab the material bags above the grouping unit 3 and place them into the car.

[0045] The square roller conveyor and the marshalling conveyor are connected together and suspended on the upper lifting frame 44 of the loading unit 4.

[0046] The traveling trolley 41 is powered by an electric motor and uses a welded steel frame structure to support the loading unit 4 and the train unit 3 as they move together.

[0047] The second traveling track 42 (shared with the mobile conveying unit 1) is fixed on the loading platform and provides support for the entire loading unit to travel along it.

[0048] The overall lifting mechanism 43 is connected to the traveling trolley 41 and the lifting frame 44. Its main function is to drive the lifting frame 44, the Y-axis rail moving car 45, the Z-axis lifting machine 46, the X-axis side adjustment mechanism 47, the loading grab 48, and the grouping unit 3 to lift together.

[0049] The lifting frame 44 is connected to the overall lifting mechanism 43, the X-axis side adjustment mechanism 47, and the grouping unit 3. Its function is to connect and lift the Y-axis track moving car 45, the Z-axis lifting machine 46, the X-axis side adjustment mechanism 47, the loading grab 48, and the grouping unit 3 together.

[0050] The Y-axis track moving vehicle 45 and the Z-axis lifting machine 46 are connected and move above the X-axis side adjustment mechanism 47. Their function is to drive the Z-axis lifting machine 46 and the loading grab 48 to move along the width of the vehicle, so that the material bag can be grabbed and accurately positioned and placed in the car body along the width of the vehicle.

[0051] The Z-axis lifting platform 46 is connected to the Y-axis rail moving vehicle 45 and the loading grab 48. Its main function is to drive the loading grab 48 to move in the vertical direction. The Z-axis lifting platform 46 is also designed with a mechanism that can drive the loading grab 48 to rotate, allowing the loading grab 48 to rotate at any angle, which provides a strong foundation for the diversification of subsequent loading and formation.

[0052] The X-axis side adjustment mechanism 47 is connected to the lifting frame 44 and carries the Y-axis rail moving vehicle 45, the Z-axis lifting machine 46, and the loading grab 48. The Y-axis rail moving vehicle 45 travels above it. The main function of the X-axis side adjustment mechanism 47 is to adjust the center distance of each side adjustment mechanism according to the different sizes of the bags, thereby overcoming the industry problem of a single model being able to simultaneously accommodate multiple sizes of bags. Furthermore, adjusting the center distance of the X-axis side adjustment mechanism 47 for bags of the same size can also achieve alternating horizontal and vertical placement, providing favorable conditions for the diversification of loading stack shapes.

[0053] The loading grabber 48 is connected to the Z-axis lifting platform 46. Its main function is to grab the material bags above the grouping unit 3 and place them into the car body through its own opening and closing mechanism. At the same time, the loading grabber 48 can rotate at multiple angles, providing favorable conditions for the diversification of subsequent loading stacks.

[0054] Application Case 1: The high-efficiency fully automatic multi-grip loader described in this invention is applied in a fully automatic loading project.

[0055] Specific requirements from the client:

[0056] 1. Loading capacity: 2000 bags / hour;

[0057] 2. Vehicle types: High-sided, low-sided, and flatbed trucks are all suitable for loading.

[0058] 3. It can be used for loading in the following two bag sizes;

[0059] Material bag I dimensions: 850mm x 550mm x 170mm (length x width x height) 50kg;

[0060] Material bag II dimensions: 810mm x 500mm x 150mm (length x width x height) 40kg.

[0061] Implementation Results: Due to the project's requirements for high loading capacity, diverse vehicle types, and loading of two different sizes of bags, this invention, a highly efficient fully automatic multi-grip loader, was selected. The loading unit is designed with three X-axis side adjustment mechanisms 47, each with two loading grippers 48 below it, for a total of six loading grippers 48 for full-horizontal bag loading. When loading bag I, the center distance between the X-axis side adjustment mechanisms 47 is 1100mm (twice the width of bag I). After loading the first six bags from the front of the truck bed, the machine needs to move back 550mm (one bag I width) before loading the second set of six bags, requiring a further 2750mm move back (five times the width of bag I), and then the loading cycle continues. If the number of rows loaded in the truck bed is not a multiple of three, the machine can calculate the most reasonable placement based on the actual length of the truck bed, ultimately completing the loading operation efficiently.

[0062] When loading bag II, the X-axis side adjustment mechanism 47 automatically adjusts its center distance to 1000mm (twice the width of bag II). The specific adjustment process is as follows: the X-axis side adjustment mechanism 47 is fixed to the lifting frame 44. The middle X-axis side adjustment mechanism 47 is fixedly connected, while the X-axis side adjustment mechanisms 47 at both ends sit on linear slide rails on the lifting frame 44. An electric push rod connects the lifting frame 44 and the X-axis side adjustment mechanism 47, allowing the X-axis side adjustment mechanism 47 to move along the vehicle length. Other loading processes are basically the same as when loading bag I. Bags can also be loaded vertically on-site; only the center distance of the X-axis side adjustment mechanism 47 needs to be adjusted. This means that the present invention can not only adapt to loading bags of various sizes but also allow for alternating horizontal and vertical placement of the same bag.

[0063] The client's requirements for this project included a variety of vehicles to be loaded, highlighting the necessity of the integrated lifting mechanism 43. Taking a flatbed truck as an example, initially, when no loading is being performed, the integrated lifting mechanism rises to its highest position, allowing sufficient clearance for vehicles to pass. When loading a flatbed truck, the integrated lifting mechanism lowers to its lowest position, minimizing the Z-axis travel while ensuring a reasonable material throwing height. As the loading height increases, the integrated lifting mechanism continuously adjusts its height, consistently minimizing the Z-axis travel to improve loading efficiency.

[0064] The embodiments of the present invention disclosed above are merely illustrative of the invention. These embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
