[0025] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0026] Example 1

[0027] This embodiment provides a bag loading device for a ton bag machine, such as Figure 1 As shown, it includes a packaging bag conveying mechanism 1, a film sensor (not shown in the figure), a suction cup device 2, a bag loading robot 3 and a material unloading barrel mechanism 4; the film sensor is arranged at the outlet side of the packaging bag conveying mechanism 1, and is used to sense whether there is a packaging bag 100 arriving at the outlet side of the packaging bag conveying mechanism 1; a suction cup device 2 is also arranged above the outlet side of the packaging bag conveying mechanism 1, and the suction cup device 2 is connected to the lifting device 5, and the lifting device 5 is used to drive the suction cup device 2 to descend to absorb the bag opening 101 of the packaging bag 100 and drive the suction cup device 2 to rise to open the packaging bag 1 00's bag opening 101; an opening and closing arm 6 is provided at one end of the bagging manipulator 3, and the opening and closing arm 6 is connected to an opening and closing drive mechanism 7, and the opening and closing drive mechanism 7 is used to drive the opening and closing arm 6 to open or close; the bagging manipulator 3 is connected to a rotation drive mechanism 8 and a linear movement mechanism 9, and the linear movement mechanism 9 is used to drive the bagging manipulator 3 to move linearly to approach the unloading barrel mechanism 4 or the packaging bag conveying mechanism 1, and the rotation drive mechanism 8 is used to drive the bagging manipulator 3 to rotate up and down to be opposite to the outlet side of the packaging bag conveying mechanism 1 or the barrel of the unloading barrel mechanism 4.

[0028] The working process of the bag loading device is as follows: the bag conveying mechanism conveys the bag from the inlet side to the outlet side. When the film sensor senses that the bag has reached the outlet side, the lifting device is triggered to drive the suction cup device to descend and adsorb one side of the bag opening of the bag, and then the suction cup device is driven to rise and drive the bag opening of the bag to rise, thereby opening the bag opening of the bag. Then the rotating driving mechanism drives the bag loading manipulator to rotate, and the bag loading manipulator drives the opening and closing arm to rotate and rotate to be opposite to the bag opening of the bag. The linear moving mechanism drives the bag loading manipulator to move toward the outlet side of the bag conveying mechanism, so that the opening and closing arm is inserted into the bag opening of the bag. The opening and closing driving mechanism drives the opening and closing arm to open and tighten the bag opening of the bag. At this time, the linear moving mechanism drives the bag loading manipulator to move toward the direction of the lower feeding barrel mechanism. The opening and closing arm uses the friction between the contact surface with the bag opening of the bag to drive the bag to move toward the direction of the lower feeding barrel mechanism until it reaches the bottom of the barrel of the lower feeding barrel mechanism. At this time, the rotary drive mechanism drives the bagging manipulator to rotate, so that the opening and closing arm drives the packaging bag to rotate to a vertical state, and the bag mouth of the packaging bag corresponds to the barrel. The barrel of the unloading barrel mechanism descends and inserts into the bag mouth of the packaging bag, and continues to descend. At the same time, the opening and closing drive mechanism drives the opening and closing arm to close and no longer tighten the bag mouth of the packaging bag. The barrel descends until the bag mouth of the packaging bag leaves the opening and closing arm, and then the unloading barrel mechanism starts unloading. Then the rotary drive mechanism drives the bagging manipulator to rotate and reset, and the linear motion mechanism drives the bagging manipulator to move back to the initial position.

[0029] Furthermore, the packaging bag conveying mechanism 1 comprises a conveyor belt device. The conveyor belt device conveys the packaging bag 100 from the inlet side to the outlet side.

[0030] As an implementation method, Figure 1 , 2 As shown, the packaging bag conveying mechanism 1 also includes a bag roll shaft 10, a bag roll shaft driving mechanism 13, and a binding rope winding device 11; the bag roll shaft 10 is used to install a bag roll 102 rolled up by multiple packaging bags 100, and each layer of the bag roll 102 has a binding rope 103 wrapped around the outer circumference of the packaging bag 100 (see CN211769198U); the bag roll shaft driving mechanism is connected to the bag roll shaft 10 and can drive the bag roll shaft 10 to rotate axially; the binding rope winding device 11 is located at the bottom of the conveyor belt device, and the end of the binding rope 103 of the bag roll 102 bypasses the conveyor belt device and is wound on the binding rope winding device 11.

[0031] Through the above-mentioned packaging bag conveying mechanism, when conveying the packaging bag, the bag roll shaft driving mechanism is used to drive the bag roll to rotate, and at the same time, the binding rope is continuously wound by the binding rope winding device. Since the binding rope and the packaging bag are in close contact, the binding rope can pull the packaging bag to be stably unfolded and laid flat on the conveyor belt device when being wound, so that it can be smoothly conveyed to the exit side of the conveyor belt device.

[0032] Furthermore, if Figure 1 As shown, the bottom of the conveyor belt device is connected to a conveyor belt lifting device 12, which is connected to the inlet side of the conveyor belt device and is used to lift the inlet side of the conveyor belt device upward to make it close to the roll bag 102. The inlet side of the conveyor belt device is close to the roll bag, and the friction between the conveyor belt device and the packaging bag can be used to more easily pull the packaging bag out of the roll bag.

[0033] In this embodiment, if Figure 2 As shown, the bag roll rotation driving device 13 is realized by using a motor 131 and a gear set 132. One end of the bag roll shaft 10 is connected to a driven gear in the gear set 132. The motor 131 drives the driving gear of the gear set 132 to rotate and drives the driven gear to rotate, thereby driving the bag roll shaft 10 to rotate.

[0034] In this embodiment, if Figure 3 As shown, the binding rope winding device 11 includes a winding motor 111, a winding rod 112 and a rotating seat 113. The winding motor is drivingly connected to one end of the winding rod 112 and can drive the winding rod 112 to rotate, and the other end of the winding rod 112 can be rotatably connected to the rotating seat 113. Specifically, the winding motor 111 drives the winding rod 112 to rotate through a pulley group 114.

[0035] In this embodiment, if Figure 4 As shown, the lifting device 5 adopts a screw-nut mechanism, and the suction cup device 2 is fixed on the nut of the screw-nut mechanism.

[0036] In this embodiment, if Figure 5 As shown, the opening and closing arm 6 includes two movable arms 61, 62, the opening and closing drive mechanism 7 is a linear module, and the linear module is provided with two sliders 71, 72 that can move toward or away from each other, and the two movable arms 61, 62 are respectively connected to the two sliders 71, 72; the linear module is fixedly connected to one end of the bagging robot 3.

[0037] More specifically, the ends of the two movable arms 61 , 62 are both provided with bag-supporting plates.

[0038] In this embodiment, the bagging robot 3 includes a fixed arm 31 and a rotating arm 32, the fixed arm 31 is connected to the linear moving mechanism 9, and the linear moving mechanism 9 can drive the fixed arm 31 to move linearly; the rotating arm 32 is rotatably connected to the fixed arm 31, and the rotating drive mechanism 8 is connected to the rotating arm 32 and can drive the rotating arm 32 to rotate around the fixed arm 31; the opening and closing arm 6 is connected to one end of the rotating arm 62. Specifically, in this embodiment, the opening and closing drive mechanism 7 is fixed to one end of the rotating arm 62.

[0039] More specifically, the rotation drive mechanism 8 adopts a hydraulic rod, the telescopic rod of the hydraulic rod is connected to the other end of the rotating arm 32, the linear motion mechanism 9 adopts a linear module, and the fixed arm is fixed on the slider of the linear module of the linear motion mechanism 9.

[0040] In this embodiment, if Figure 6 , 7 As shown, the unloading barrel mechanism 4 includes a barrel 41 and a barrel lifting device 42, the barrel 41 is installed on the barrel lifting device 42, and the barrel lifting device 42 can drive the barrel 41 to move up and down; a butterfly valve 43 is provided at the upper end of the barrel 41 for controlling the closing or opening of the upper end of the barrel 41.

[0041] Furthermore, the unloading barrel mechanism 4 further includes a bag opening clamping arm 44, which corresponds to the barrel 41 and can move toward or away from the barrel 41, and is installed together with the barrel 41 in the barrel lifting device 42. The function of the bag opening clamping arm 44 is that when the barrel 41 descends to the bag opening for inserting the packaging bag, the bag opening clamping arm 44 moves toward the barrel 41 and clamps the bag opening of the packaging bag on the barrel wall of the barrel 41.

[0042] More specifically, in this embodiment, the barrel lifting device 42 is a chain lifting device.

[0043] Example 1

[0044] This embodiment is basically the same as embodiment 1, the main difference is that Figure 8 As shown, the packaging bag conveying mechanism 1 of this embodiment is not provided with a bag rolling shaft, a bag rolling shaft driving mechanism, a binding rope winding device and a conveyor belt lifting device, and only includes a conveyor belt device. When operating, the packaging bags 100 are unfolded one by one and placed flat on the conveyor belt device, and the conveyor belt device is allowed to convey to the exit side. It should be noted that Figure 8 The opening and closing arm is shown in a state where it is rotated downward to correspond to the exit side of the conveyor belt device.

[0045] For those skilled in the art, various corresponding changes and modifications can be made according to the above technical solutions and concepts, and all of these changes and modifications should be included in the protection scope of the claims of the present invention.
