[0002] In the transportation of materials such as bagging and boxing, as well as commercial logistics and warehousing, container loading is often required. In this process, most of the loading is done manually, which is labor-intensive, inefficient, and prone to errors. Therefore, the design of a simple, fast, and low-cost automatic palletizer in the box is the direction pursued by those skilled in the art. Summary of the invention

[0003] The invention provides an automatic box packing device inside a container, which is used for automatic transportation and stacking of different bags and boxes from outside the container to inside the container.

[0004] The technical solution to achieve the above-mentioned purpose is: an automatic palletizer inside a container, comprising a connecting part, a frame part, a grabbing part, a unloading part, a detecting part, and a feeding part, wherein the connecting part, the grabbing part, the unloading part, the detecting part, and the feeding part are all connected to the frame part, the unloading part is located at the front part of the frame part, the connecting part is located at the rear lower part of the frame part, and the grabbing part is located at the upper part of the frame part.

[0005] Preferably, the connecting part connects the frame part and the feeding part, and the connecting part is composed of two sets of linear guides, connecting bearings and connecting plates. The base of the linear guide is fixed to the frame part, and the connecting plate fixes the two sides of the front end of the feeding part. The connecting part adjusts the spatial position relationship between the automatic palletizer and the feeding part inside the container.

[0006] Preferably, the frame part includes a ball screw, a frame, a bearing platform, universal wheels, and a motor. The frame adopts a high-quality steel welding structure. The ball screw is located on the inner side of the front part of the frame, and the bearing platform is located at the lower part of the frame. The bearing platform is flush with the working surface of the feeding part to facilitate the transportation of materials; three universal wheels are installed at the bottom of the frame, and the universal wheels are distributed in a triangle, one in the front and two in the back; the motor is located at the bottom of the frame and the rear of the bearing platform, driving the three universal wheels.

[0007] Preferably, the detection part includes a unloading sensor and a detection sensor. A pair of the detection sensors are placed on both sides of the front part of the frame at the height of every other layer of material. The number of the detection sensors placed is related to the height of the material and the container, and is used to detect the rising or falling position of the unloading part; the detection sensors are located on both sides of the rear side of the loading platform to detect whether the material from the feeding part has reached the loading platform.

[0008] Preferably, the grabbing part includes a movable gripper, a transfer rod, a gripper pushing cylinder, a manipulator fixing plate, and a three-coordinate mechanism. The gripper pushing cylinder controls the opening or closing of the movable gripper through the transfer rod. When the grabbing part is opened, the movable gripper is parallel to the inner wall of the container. When the detection sensor detects that the material has arrived at the loading platform, the grabbing part reaches above the loading platform along the three-coordinate mechanism. Driven by the gripper pushing cylinder, the transfer rod controls the movable gripper to open and grab the material. Then the grabbing part moves along the three-coordinate mechanism to a suitable position above the unloading part, and the movable gripper opens to put down the material.

[0009] Preferably, the unloading part comprises a unloading pushing plate, a unloading pushing baffle, a unloading supporting plate, a unloading plate pushing cylinder and a unloading baffle pushing cylinder, wherein the unloading supporting plate is fixed on the ball screw and rotates with the ball screw to reach different unloading positions, and the unloading supporting plate drives the unloading part to move up and down along the frame; the unloading pushing plate is supported above the unloading supporting plate, and the unloading plate pushing cylinder and the unloading baffle pushing cylinder are respectively fixed on the unloading supporting plate, the piston rod of the unloading plate pushing cylinder is connected with the unloading pushing plate, and the piston rod of the unloading baffle pushing cylinder is connected with the unloading pushing baffle; the piston rods of the unloading plate pushing cylinder and the unloading baffle pushing cylinder are pushed out, and the unloading pushing plate carrying the material moves outwards together with the unloading pushing baffle along the unloading supporting plate, and the piston rods of the unloading plate pushing cylinder and the unloading baffle pushing cylinder are withdrawn in turn, and the material falls to the stacking position under the action of its own gravity.

[0010] The beneficial effects of the present invention are as follows: the material is sent to the carrying platform through the feeding part, grabbed by the manipulator, and placed on the unloading part through the three-coordinate mechanism. The unloading part is unloaded to the first layer of the container, and stacked layer by layer until the top layer is stacked. Then, the automatic palletizer and the feeding part inside the container retreat a proper distance, and stack rows from front to back. The stacking process is fully automated. Because the movable gripper is parallel to the inner wall of the container when the manipulator is opened, no additional space is occupied, which is conducive to stacking the material as close to the side wall of the container as possible, without wasting space, saving manpower and improving work efficiency.

DETAILED DESCRIPTION

[0017] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1 , 2As shown in Figures 3, 4 and 5, an automatic palletizer inside a container according to the present invention comprises: a connecting part 5, a frame part 2, a grabbing part 3, a unloading part 1, a detecting part 4 and a feeding part 6. The connecting part 5 includes a linear guide 51, a connecting bearing 52, and a connecting plate 53; the frame part 2 includes a ball screw 21, a frame 22, a bearing platform 23, a universal wheel 24, and a motor 25; the grasping part 3 includes a movable gripper 31, a transfer rod 32, a gripper push-out cylinder 33, a manipulator fixing plate 34, and a three-coordinate mechanism 35; the unloading part 1 includes a unloading push-out baffle 11; a unloading push-out plate 12, a unloading support plate 13, a unloading baffle push-out cylinder 14, and a unloading plate push-out cylinder 15; the detection part 4 includes a unloading sensor 41 and a detection sensor 42; the grasping part 3 is arranged at the upper part of the frame part 2, the unloading part 1 is arranged at the front part of the frame part 2, the connecting part 5 is arranged at the rear lower part of the frame part 2, the bearing platform 23 is arranged at the lower part of the frame 22, the motor 25 is located at the lower part of the frame 22 and the rear part of the bearing platform 23, and the universal wheel 24 is arranged at the lower part of the frame 22, distributed in a triangle, one at the front and two at the back.

[0019] The automatic palletizer inside the container is connected by a connecting part 5 and a feeding part 6, wherein a connecting plate 53 connects the feeding part 6, a linear guide base 51 is connected to the frame part 2, and the linear guide 51 and the connecting bearing 52 jointly adjust the spatial position relationship between the automatic palletizer inside the container and the feeding part inside the container. The material is transported to the carrier 23 by the feeding part 6. After the detection sensor 42 detects the material, the grabbing part 3 reaches the top of the carrier 23 along the three-coordinate mechanism 35. Driven by the gripper push cylinder 33, the transfer rod 32 controls the movable gripper 31 to open and grab the material. Then the grabbing part 3 moves along the three-coordinate mechanism 35 to the appropriate position above the unloading part 1, and the movable gripper 31 opens to put down the material. When the detection sensor 42 detects the material, the grabbing part 3 grabs it again. Repeat the above steps, and the grabbing part 3 fills the unloading push plate 12 with bagged or boxed materials. The unloading part 1 is lowered to the designated position through the unloading sensor 41 and the ball screw 21, and the unloading push-out baffle 11, together with the unloading push-out plate 12 and the material are pushed out by the unloading plate push-out cylinder 14 and the unloading baffle push-out cylinder 15. Then the unloading push-out plate 12 is pulled back by the unloading plate push-out cylinder 15, while the unloading push-out baffle 11 does not move. At this time, the material does not move in the original position due to the blocking effect of the unloading push-out baffle 11. When the unloading push-out plate 12 is completely withdrawn, the material falls to the stacking position due to its own gravity, and then the unloading push-out baffle 11 returns to the original position under the action of the unloading baffle push-out cylinder 14. At this time, the ball screw 21 rotates in the opposite direction, driving the unloading part 1 back to the material receiving position, waiting for the grabbing part 3 to stack again, and repeating the above steps to fill a row. Driven by the motor 25, the automatic stacker and the feeding part 6 inside the container retreat a proper distance, and then continue to stack the next row until the entire container is filled.
