Of course, for the suction bag device 4 to suck up the bag opening of the ton bag, the bag clamping device 6 to clamp up the bag ear of the ton bag, the bag supporting device 7 to open the bag ear of the ton bag, etc., the controller can also take the image of the ton bag as a reference, and drive the suction bag device 4, the bag clamping device 6 and the bag supporting device 7 to move in space. Preferably, at least one mark point can be arranged on the ton bag, so that the controller can easily judge the orientation of the ton bag according to the mark point in the image of the ton bag, and conveniently control the displacement device 3 to adjust the positions of the devices in space.

[0063] In some embodiments, referring to Figure 3, the ton bag upper bag machine further comprises two pressing devices 9, both of which are connected to the displacement device 3 and located above the tray 2, and are respectively located on the opposite sides of the bag suction device 4, and are respectively connected to the controller; preferably, the two pressing devices 9 are arranged on one side of the mounting plate 3111 close to the bearing plate 3132 and are respectively located at the opposite ends of the through hole 3112, and the two pressing devices 9 are arranged in a staggered manner. Based on this, the displacement device 3 is further used to drive the two pressing devices 9 to move in space; the controller is further used to control the two pressing devices 9 to press the opposite sides of the ton bag respectively before controlling the bag suction device 4 to suck up the bag opening of the ton bag, and to control the two pressing devices 9 to move away from the ton bag to cancel the pressing of the ton bag respectively after controlling the bag suction device 4 to suck up the bag opening of the ton bag. It can be understood that if the opposite sides of the ton bag are not pressed before the bag suction device 4 sucks up the bag opening of the ton bag, it is likely that the ton bag will be sucked up entirely due to the excessive suction force of the bag suction device 4, which hinders the subsequent opening of the bag opening of the ton bag by the two bag opening devices 5, so the application sets the pressing device 9. Exemplarily, the pressing device 9 comprises a piston cylinder and a flexible pressing rubber block with good performance, and the pressing rubber block is connected to the piston rod of the piston cylinder.

[0064] In some embodiments, referring to Figure 3 , the ton bag upper bag machine further comprises two clamping devices 10 respectively connected to the controller, both of which are connected to the displacement device 3 and located above the tray 2, and are respectively located on the opposite sides of the bag suction device 4; preferably, the two clamping devices 10 are arranged on the bearing plate 3132 and are respectively located at the opposite ends of the plurality of first suction cups 42. Based on this, the displacement device 3 is further used to drive the two clamping devices 10 to move in space; the controller is further used to control the two clamping devices 10 to clamp the opposite ends of the bag opening respectively after controlling the bag suction device 4 to suck up the bag opening of the ton bag, and to control the two clamping devices 10 to release the opposite ends of the bag opening of the ton bag at the same time as the bag suction device 4 releases the bag opening. It can be understood that if the opposite ends of the bag opening are not clamped after the bag suction device 4 sucks up the bag opening of the ton bag, it is likely that the bag opening of the ton bag will fall off the bag suction device 4 due to unstable suction force of the bag suction device 4, which affects the subsequent opening of the bag opening of the ton bag by the two bag opening devices 5, so the application sets the clamping device 10. Exemplarily, the clamping device 10 comprises a rotary cylinder and a clamping plate, the clamping plate is connected to the rotary cylinder, and the controller can realize the clamping of the opposite ends of the bag opening of the ton bag by controlling the rotary cylinder to drive the clamping plate to open or close.
