[0027] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0028] An automatic cement loading machine for bags includes a loading bin 1 with open front and rear openings. A crossbeam 2 is fixed in the middle of the loading bin 1. First slide rails 3 are respectively arranged on both sides of the top of the crossbeam 2 along the length of the crossbeam 2. Conveyor units are arranged in the middle of the two side walls of the loading bin 1 and between the entrance and the lower end of the crossbeam 2. Each first slide rail 3 has a gripping mechanism slidably connected to both sides for use in conjunction with the adjacent conveyor unit.

[0029] Furthermore, a pressing mechanism is installed on the top of the conveyor unit near the inlet side to separate the connected bagged cement, allowing only one bag of cement to pass through at a time, thus ensuring the normal spacing between the bagged cement.

[0030] Furthermore, the pressing mechanism includes a first gantry frame 4 and a second gantry frame 5 spanning the conveyor unit. The height of the crossbar of the first gantry frame 4 is lower than the height of the crossbar of the second gantry frame 5. A baffle 6 is rotatably connected to the crossbar of the first gantry frame 4. A first cylinder 7 is hinged between the top of the baffle 6 on the side away from the first gantry frame 4 and the crossbar of the second gantry frame 5. The first cylinder 7 presses down to lower the rear end of the baffle 6, thereby separating the bagged cement from the connected bags through the baffle 6.

[0031] Furthermore, the gripping mechanism includes a positioning plate 8 located on the side of the crossbeam 2. A first slider is provided on the back side of the positioning plate 8, which is slidably engaged with the first slide rail 3. A first rack 9 is provided on the front and back sides of the crossbeam 2 along the length direction, with the teeth of the first rack 9 facing downwards. A first motor 10 is provided on one side of the front of the positioning plate 8. The output end of the first motor 10 passes through the positioning plate 8 and is fitted with a first gear that meshes with the first rack 9. A longitudinal moving component is provided in the middle of the front of the positioning plate 8. A material-grabbing clamp is provided at the bottom of the longitudinal moving component. The first motor 10 drives the first gear to rotate, thereby driving the positioning plate 8 to move along the length direction of the crossbeam 2. The X-axis position of the material-grabbing clamp is adjusted by the first motor 10.

[0032] Furthermore, the longitudinal movement component includes a moving tube 11 located in the center of the front of the positioning plate 8. The moving tube 11 is a square tube, and the top of the moving tube 11 extends upward to the loading compartment 1. Second slide rails 12 are provided on both sides of the moving tube 11. Second sliders that slide and engage with the second slide rails 12 are respectively provided on the positioning plate 8 and located on both sides of the moving tube 11. A second rack 28 is provided on the opposite surface of the moving tube 11 and the positioning plate 8. A second motor 13 is provided on the back side of the positioning plate 8 and above the crossbeam 2. The output end of the second motor 13 passes through the positioning plate 8 and is fitted with a second gear that meshes with the second rack 28. The material picker is located at the bottom of the moving tube 11. The second motor 13 drives the second gear to rotate, thereby driving the moving tube 11 to move longitudinally. The Y-axis position of the material picker is adjusted by the second motor 13.

[0033] Furthermore, the material handling clamp includes an installation frame 14 located at the bottom of the moving tube 11. An installation plate is provided on the bottom surface of the moving tube 11. A hollow rotating platform 15 is provided between the installation plate and the installation frame 14. Mechanical grippers are provided on both sides of the bottom of the installation frame 14. The mechanical grippers at the bottom are rotated by the hollow rotating platform 15. After the mechanical grippers grab the bagged cement, they move along the X-axis to the unloading point above the truck and then move down along the Y-axis. The hollow rotating platform 15 rotates 90° to place the cement on the truck.

[0034] Furthermore, the axis of the rotating platform of the hollow rotating platform 15 is opposite to the center of the mounting frame 14.

[0035] Furthermore, the axis of the rotating platform of the hollow rotating platform 15 is eccentrically set with respect to the center of the mounting frame 14. This eccentric setting allows the bagged cement to rotate closer to the inner side of the two first slide rails 3, resulting in less space occupied by the two rows of bagged cement. When the bagged cement is rotated 90° and placed inside the vehicle, the axis of the rotating platform of the hollow rotating platform 15 is located on the side of the center of the mounting frame 14 away from the first slide rail 3.

[0036] Furthermore, the mechanical gripper includes second cylinders 16 hinged to the top two sides of the mounting frame 14 and with opposite output directions. A Y-shaped connecting plate 17 is hinged to the output end of the second cylinder 16. A connecting shaft is fixedly inserted through the opening of the connecting plate 17. A connecting seat 18 rotatably connected to the connecting shaft is provided at the top of the mounting frame 14. Grooved gripper brackets 19 are provided opposite to each other on the bottom two sides of the mounting frame 14. A rotating rod 20 perpendicular to the second cylinder 16 is rotatably connected between the bottom ends of the two gripper brackets 19 on opposite sides. The frame 14 is equipped with a clamping tooth 21. A gear structure is provided on the middle of the connecting shaft and the adjacent rotating rod 20, and a transmission chain 22 is fitted on it. The bottom of the mounting frame 14 is provided with spring rods 23 arranged in a square. The ends of the spring rods 23 are provided with pressure plates 24. The second cylinder 16 at the top of the mounting frame 14 works together to drive the connecting plate 17 and the connecting shaft to rotate. In turn, the transmission chain 22 drives the rotating rod 20 to rotate, causing the teeth to open and close. When gripping, the spring rods 23 are compressed, causing the pressure plate 24 to press against the top of the bagged cement and compress the bagged cement.

[0037] Furthermore, the conveyor unit includes a belt conveyor 25 near the inlet side and a roller conveyor 26 located below the crossbeam 2. The first gantry frame 4 and the second gantry frame 5 are straddling the belt conveyor 25. The roller conveyor 26 is provided with guard plates 27 on both sides, which are opposite to the rollers and cooperate with the clamping teeth 21. The clamping teeth 21 extend into the rollers of the roller conveyor 26 through the guard plates 27 to clamp the bagged cement and prevent it from colliding with the conveyor.

[0038] After the truck stops in loading bay 1, bagged cement is transported forward on both sides of the truck via belt conveyor 25 and roller conveyor 26. If there are connected bags, baffles 6 separate them. The gripping mechanism is divided into two groups, each containing two grippers. The first motor 10 drives the displacement in the X-axis direction, and the second motor 13 drives the displacement in the Y-axis direction to position the gripper. Then, the second cylinder 16 controls the gripper teeth 21 to pick up the bagged cement. The spring rod 23 compresses the pressure plate 24 to press the bagged cement tightly. Then, the movement of the X and Y axes is controlled to grip the bagged cement on both sides of the truck and transport it towards the middle of the truck. The truck bed is rectangular, and the bagged cement is also rectangular. After being transported on the conveyor group, in order to ensure the stability of the truck during transport, the long side of the cement bag must coincide with the short side of the truck bed. Therefore, the bagged cement is placed after being rotated 90 degrees in the placement position. The gripping mechanism of the same group places the bagged cement in the same row in the truck, saving manpower and making the arrangement neat.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
