[0022] Among them, the rice bag conveying mechanism A and the carton conveying mechanism B can be belt conveyors, roller conveyors, etc. for transporting rice bags and cartons. Other specific structures will be described in detail later. Among them, the rice bag lifting and moving mechanism D is used to transfer the rice bags on the rice bag conveying mechanism A to the cartons on the carton conveying mechanism B, and it can be a manipulator or the specific structure described below.

[0023] Among them, the rice bag lifting and moving mechanism D includes a first frame D1 fixedly provided on the frame 1, a first horizontal sliding seat D2 slidably connected to the first frame D1, and a first vertical frame D3 fixedly provided on the first horizontal sliding seat D2. The first vertical frame D3 is connected with a first vertical sliding seat D4 in a lifting and sliding manner. A plurality of suction cup assemblies D5 capable of grasping and transferring the rice bags in the rice bag conveying mechanism to the cartons in the carton conveying mechanism are connected to the first vertical sliding seat D4. Four groups are taken as an example in the figure. The above first horizontal sliding seat D2 can slide along the Y direction shown in the figure, and the first vertical sliding seat D4 can slide along the Z direction shown in the figure.

[0024] On the first frame D1, there are second synchronous pulleys D23 arranged in parallel at intervals. A second synchronous belt D24 is connected between the two second synchronous pulleys D23. One of the two second synchronous pulleys D24 is directly driven or indirectly driven (driven by a motor through a speed reducer or a pulley mechanism) by a second synchronous belt motor D25 to rotate. A first horizontal slide D2 is fixedly connected to the second synchronous belt. Through the action of the second synchronous belt motor D25, the first horizontal slide D2 slides along the Y direction shown in the figure (the first frame D1 has a guide rail for supporting the sliding of the first horizontal slide D2).

[0025] On the first vertical frame D3, there are third synchronous pulleys D26 arranged in parallel at intervals. A third synchronous belt D27 is connected between the two third synchronous pulleys D26. One of the two third synchronous pulleys is driven to rotate by a third synchronous belt motor D28.

A number of groups of rotating shafts D10 (taking 4 groups as an example in the figure) are rotatably connected to the first cross beam D8. The lower end of the rotating shaft is connected with the above-mentioned suction cup assembly D5. The negative pressure pipeline of the suction cup assembly is connected in series with an electromagnetic valve D11 located on the first cross beam to control the suction and release of the suction cup D12.

[0027] Specifically, four rotating shafts D10 are rotatably connected to the bottom surface of the first cross beam D8.

The outer periphery of the suction cup tube has an external thread and the upper part passes through a perforation on the mounting plate. The upper and lower parts of the suction cup tube passing through the mounting plate are locked by nuts D20. Multiple suction cup tubes D18 and suction cups D12 can be installed through the mounting plate D19 and multiple perforations thereon, and the locking by nuts D20 is stable and reliable.

The free end of the telescopic rod of the first horizontal telescopic cylinder D9 is fixedly connected to the second support plate D22 on the first cross beam D8. Through the action of the first horizontal telescopic cylinder D9, the first cross beam D8 can move relative to the first seat plate in the X direction.

[0031] The rice bag lifting and moving mechanism of the present utility model drives the first cross beam to move through the action of the first horizontal telescopic cylinder, so as to realize the movement of the rice bag adsorbed by the suction cup in the first direction. Through the vertical sliding of the first vertical sliding seat, the movement of the rice bag adsorbed by the suction cup in the second direction is realized. Through the horizontal movement of the first horizontal sliding seat, the movement of the rice bag adsorbed by the suction cup in the third direction is realized, so as to meet the movement of the rice bag in three directions during the boxing process. In addition, through the rotating shaft of the first cross beam, the rotation of the rice bag adsorbed by the suction cup is realized. Through this rice bag lifting and moving mechanism, the rice bag can be transferred from the rice bag conveying mechanism to the carton conveying mechanism.
