Description

Technical Field

[0001] This invention relates to the field of material packaging vehicle technology, and in particular to an automatic single-arm loading machine for hoisting bagged material packages. Background Technology

[0002] Existing mature single-grip hoisting loading machines on the market typically consist of three parts: a rotating platform, a feeding conveyor belt, and a front-end palletizing gripper. The rear end of the conveyor belt is fixed to the rotating platform, and the front end is equipped with a palletizing gripper. The rotating platform can achieve two degrees of freedom of movement: rotation and pitch, thereby enabling the feeding conveyor belt to swing left and right and to pitch up and down. The palletizing gripper is located at the front end of the feeding conveyor belt. As the conveyor belt swings left and right, the palletizing gripper can move left and right, and as the conveyor belt pitches up and down, the palletizing gripper can move up and down. The left and right movement of the palletizing gripper mainly meets the needs of the loading machine to stack material bags in the same row at three positions (left, center, and right) in the truck compartment. The up and down movement of the palletizing gripper is mainly to ensure that the palletizing gripper lowers the drop height of the bags as much as possible during loading, thereby avoiding problems such as unstable bag shape and bag breakage caused by the loading machine dropping bags too high during loading.

[0003] However, existing hoisting single-grip loading machines have two problems: 1. When loading high-sided vehicles, these machines cannot reach into the truck bed due to their structure. The palletizing gripper must be higher than the truck bed, so the material bags can only be thrown high, resulting in poor loading performance for high-sided vehicles; 2. The loading machine controls its movement through a swinging and pitching feeding conveyor belt and a palletizing gripper. The feeding conveyor belt and palletizing gripper are heavy, and their swinging and pitching drives are located on the rotating platform at the rear of the feeding conveyor belt. According to the principle of reverse lever, their load inertia is huge relative to the rotating platform, which inevitably makes the loading and palletizing movement less flexible and the loading efficiency lower, failing to meet the requirements of high-speed loading. Therefore, a hoisting automatic single-arm loading machine for bagged material bags is proposed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this invention proposes an automatic single-arm loading machine for hoisting bagged material packages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hoisting type automatic single-arm loading machine for bagged material packages, comprising two trusses, a main conveyor line between the two trusses, and a frame one and a frame two slidably mounted below the two trusses. A secondary conveyor line is provided between the frame one and the frame two. A traveling mechanism is provided on the frame two, which drives the frame one and the frame two to move synchronously below the two trusses. A palletizing and gripping mechanism is also provided on the frame two. A chute and an inclined guide conveyor belt are provided on the frame one. The guide conveyor belt is used to transfer the material packages conveyed on the main conveyor line to the chute. After the material packages fall into the chute, they are transferred to the connecting mechanism via the secondary conveyor line. An adjustment mechanism is also provided on the frame two, which drives the palletizing and gripping mechanism to move bidirectionally and to rotate.

[0006] Preferably, the auxiliary conveyor line includes a frame 1 for connecting frame 1 and frame 2. The frame 1 is inclined, and the end of the frame 1 near frame 1 is higher than the end near frame 2. The frame 1 is provided with two conveyor belts 1. The auxiliary conveyor line also includes a frame 2 horizontally arranged on frame 2, and the frame 2 is provided with conveyor belts 2.

[0007] Preferably, the adjustment mechanism includes an electric linear module one that is horizontally fixed on the frame two, an electric linear module two that is vertically arranged fixedly installed on the slider of the electric linear module one, a motor one that is fixedly installed on the slider of the electric linear module two, and the output shaft end of the motor one that is fixedly connected to the palletizing gripping mechanism.

[0008] Preferably, the palletizing and gripping mechanism includes a connecting plate fixedly connected to the end of an output shaft of a motor. Both sides of the connecting plate are provided with bucket frames with one side open. The two bucket frames are connected to the connecting plate by hinges. The side of the connecting plate away from the openings of the two bucket frames is provided with an opening and closing mechanism, which is used to drive the two bucket frames to rotate synchronously in opposite directions.

[0009] Preferably, a round shaft is fixedly installed on the side of each of the two bucket frames that are far apart from each other. The round shaft includes a housing that is fixedly connected to the connecting plate. Two gears four are rotatably installed inside the housing. Gears two and three are respectively meshed on the two gears four. Gears two and three are meshed together. A motor two with an output shaft fixedly connected to gear three is fixedly installed on one side of the housing. A shaft is fixedly installed on each of the two gears four. A swing arm two is fixedly sleeved on each of the two shafts. The same swing arm one is hinged between adjacent swing arms two and the round shaft.

[0010] Preferably, the truss includes I-beam one and I-beam two, which are fixedly connected by multiple reinforcing ribs. The traveling mechanism includes a dual-axis motor rotatably mounted on the top of the frame two and two rotating shafts. Gear one is fixedly mounted on the ends of the two rotating shafts that are far apart from each other, and the ends of the two rotating shafts that are close to each other are fixedly connected to the two output ends of the dual-axis motor. Racks are fixedly mounted on the bottom of the two I-beams, and the two gears one are respectively meshed with the corresponding racks.

[0011] Preferably, four connecting mechanisms arranged in a rectangular pattern are fixedly installed on the top of both frame one and frame two. The multiple connecting mechanisms on frame one and frame two are respectively installed on two I-beams. Each connecting mechanism includes a rectangular plate one, and two rectangular plates two are fixedly installed on the top of the rectangular plate one. Two rollers are rotatably installed on the side of the two rectangular plates two that are close to each other. The four rollers are all rolled on the lower flange of the I-beam one, and the two coaxially arranged rollers are respectively arranged on both sides of the web of the I-beam one.

[0012] Preferably, the walking mechanism further includes two wheel frames fixed to the top of the frame two, and guide wheels are rotatably installed on the opposite sides of the two wheel frames, with the two guide wheels abutting against the webs of the two I-beams one respectively.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention offers high loading efficiency. The adjustment mechanism increases the independent degrees of freedom in two directions of the palletizing and gripping mechanism, thereby accelerating loading efficiency. The adjustment mechanism also increases the vertical movement freedom of the palletizing and gripping mechanism, allowing it to reach into the interior of high-sided wagons for high-quality loading.

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please refer to Figure 1 - Figure 9This invention provides a technical solution: an automatic single-arm loading machine for bagged material packages, comprising two trusses 1, a main conveyor line 2 between the two trusses 1, a frame 3 and a frame 4 slidably mounted below the two trusses 1, a common auxiliary conveyor line 5 between the frame 3 and the frame 4, a traveling mechanism 6 on the frame 4 for driving the frame 3 and the frame 4 to move synchronously below the two trusses 1, a palletizing and gripping mechanism 9 on the frame 4, a chute 101 and an inclined guide conveyor belt 10 on the frame 3 for transferring the material packages conveyed on the main conveyor line 2 to the chute 101, and after the material packages fall into the chute 101, they are transferred to the connecting mechanism 7 via the auxiliary conveyor line 5, and an adjusting mechanism 8 on the frame 4 for driving the palletizing and gripping mechanism 9 to move bidirectionally and to rotate.

[0018] The auxiliary conveyor line 5 includes a frame 51 for connecting frame 3 and frame 4. The frame 51 is inclined, with the end of the frame 51 near frame 3 being higher than the end near frame 4. The frame 51 is provided with two conveyor belts 53. The auxiliary conveyor line 5 also includes a frame 52 horizontally arranged on frame 4. The frame 52 is provided with a conveyor belt 54.

[0019] Furthermore, when multiple packages are connected, they need to be separated. Therefore, two conveyor belts 54 are designed here mainly for package control and package breakage handling. This ensures that the next package will only fall onto the conveyor belt 54 and be transported into the palletizing and gripping mechanism 9 when the previous package has been stacked in the carriage and is ready to receive the next package. The conveyor belt 54 is used to increase the moving speed of the package. When the package falls onto the conveyor belt 54, the conveyor belt 54 increases the moving speed of the package and uses the inertia of the package to rush into the palletizing and gripping mechanism 9.

[0020] The adjustment mechanism 8 includes an electric linear module 81 that is horizontally fixed on the frame 4. A vertically arranged electric linear module 82 is fixedly installed on the slider of the electric linear module 81. A motor 83 is fixedly installed on the slider of the electric linear module 82. The output shaft end of the motor 83 is fixedly connected to the palletizing gripping mechanism 9.

[0021] The palletizing and gripping mechanism 9 includes a connecting plate 91 fixedly connected to the end of the output shaft of motor 83. Both sides of the connecting plate 91 are provided with bucket frames 92 with one side open. The two bucket frames 92 are connected to the connecting plate 91 by a hinge 93. The side of the connecting plate 91 away from the opening of the two bucket frames 92 is provided with an opening and closing mechanism 97. The opening and closing mechanism 97 is used to drive the two bucket frames 92 to rotate synchronously in opposite directions.

[0022] Two bucket frames 92 are each fixedly mounted with a round shaft 94 on the side away from each other. The round shaft 94 includes a housing 971 fixedly connected to the connecting plate 91. Two gears 974 are rotatably mounted inside the housing 971. Gears 972 and 973 are respectively meshed on the two gears 974. A motor 975 with an output shaft fixedly connected to gear 973 is fixedly mounted on one side of the housing 971. A shaft 976 is fixedly mounted on each of the two gears 974. A swing arm 96 is fixedly sleeved on each of the two shafts 976. The same swing arm 95 is hinged between adjacent swing arms 96 and the round shaft 94.

[0023] Furthermore, such as Figure 8 As shown, when motor 2 975 drives gear 3 973 to rotate counterclockwise, gear 4 974 on the left rotates clockwise, while gear 4 974 on the right rotates counterclockwise due to the conversion of gear 2 972, thus achieving the effect of the two gears 4 974 driving the two shafts 976 to rotate synchronously in opposite directions.

[0024] Furthermore, such as Figure 7 As shown, when the left swing arm 96 rotates clockwise and the right swing arm 96 rotates counterclockwise, the two swing arms 95 will push the two round shafts 94 to drive the two bucket frames 92 to rotate around the corresponding hinges 93. During this process, the bottoms of the two bucket frames 92 move away from each other. If the material bag is inside the two bucket frames 92, it will fall from the channel between the two bucket frames 92 as the two bucket frames 92 rotate.

[0025] The truss 1 includes I-beam 11 and I-beam 22, which are fixedly connected by multiple reinforcing ribs 13. The traveling mechanism 6 includes a dual-axis motor 63 rotatably mounted on the top of the frame 2 4 and two rotating shafts 61. Gear 1 62 is fixedly mounted on the ends of the two rotating shafts 61 that are far apart from each other, and the ends of the two rotating shafts 61 that are close to each other are fixedly connected to the two output ends of the dual-axis motor 63. Racks 14 are fixedly mounted on the bottom of the two I-beams 11, and the two gears 1 62 are respectively meshed with the corresponding racks 14.

[0026] Furthermore, the two trusses 1 are suspended at a high position by corresponding I-beams 2 12.

[0027] Four connecting mechanisms 7 arranged in a rectangular pattern are fixedly installed on the top of both frame 3 and frame 4. The multiple connecting mechanisms 7 on frame 3 and frame 4 are respectively installed on two I-beams 11. The connecting mechanism 7 includes a rectangular plate 71. Two rectangular plates 72 are fixedly installed on the top of the rectangular plate 71. Two rollers 73 are rotatably installed on the side of the two rectangular plates 72 that are close to each other. The four rollers 73 are all rolled on the lower flange of the I-beam 11, and the two rollers 73 arranged coaxially are respectively located on both sides of the web of the I-beam 11.

[0028] Furthermore, the dual-axis motor 63 drives two rotating shafts 61 to rotate synchronously, and the two rotating shafts 61 in turn drive two gears 62 to rotate synchronously. During the rotation of gear 62, through the meshing connection with rack 14, while the position of rack 14 remains unchanged, gear 62 can rotate on its own axis and also translate below rack 14, ultimately achieving the translation of the entire frame 4 below the two trusses 1. Frame 3 and frame 4 are connected by auxiliary conveyor line 5, ultimately enabling frame 3 and frame 4 to move synchronously below the two trusses 1.

[0029] The walking mechanism 6 also includes two wheel frames 64 fixed to the top of the frame 2 4. Guide wheels 65 are rotatably installed on the opposite sides of the two wheel frames 64. The two guide wheels 65 abut against the webs of the two I-beams 11 respectively.

[0030] Furthermore, by having two guide wheels 65 abutting against the webs of the two I-beams 11, it is possible to prevent the entire device from swaying during operation, thus ensuring the smooth operation of the entire device.

[0031] In this embodiment: When in use, the material package is first conveyed on the main conveyor line 2 towards the guide conveyor belt 10. After the material package comes into contact with the guide conveyor belt 10, the guide conveyor belt 10 can change the conveying direction of the material package and transfer it to the chute 101. After the material package falls on the chute 101, it will slide down towards the auxiliary conveyor line 5 under the action of gravity. The material package is conveyed by two conveyor belts 53 and 54 in sequence. Finally, the material package will be transferred to the two bucket frames 92 on the palletizing and gripping mechanism 9. Then, the walking mechanism 6 drives the entire device to move under the two trusses 1. When the palletizing and grabbing mechanism 9 moves above the car to be loaded, the left and right position and vertical height of the palletizing and grabbing mechanism 9 above the car can be adjusted by the adjusting mechanism 8. When the palletizing and grabbing mechanism 9 is in the target position, the two bucket frames 92 can be opened by the opening and closing mechanism 97, so that the material bag falls to the designated placement position on the car.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
