[0024] The XYZ three-axis shifting mechanism 4 is a common mechanism in existing CNC machine tools. In the present invention, the Z axis is the vertical direction, the Y axis is the direction parallel to the conveying direction of the package conveyor 2 in the horizontal plane, and the X axis is the direction perpendicular to the Y axis in the horizontal plane.

[0025] The X-axis mechanism 41 in the present invention is composed of a 2kW servo motor, a 16B double-row sprocket, a synchronous wheel, a synchronous belt, etc. The double-row sprocket is used at the output drive end of the servo motor to increase rigidity and prolong the service life of the chain. The X-axis mechanism 41 is used to drive the Z-axis mechanism 43 and the Y-axis mechanism 42 to move accurately and quickly in the X-axis direction; the Z-axis mechanism 43 is composed of a 1.5kW servo motor, a double-row sprocket, a synchronous belt and synchronous wheel, etc., and the main working process is to drive the Y-axis mechanism to move in the vertical direction. The Y-axis mechanism 42 is composed of a 0.75kW servo motor, etc., and the main working process is to make movement compensation in the Y-axis direction according to demand to meet production needs. The packaging box suction process is completed by the X-axis, Y-axis, and Z-axis mechanisms. The X-axis, Y-axis, and Z-axis are all driven by servo motors, which can achieve rapid movement and precise positioning.

[0026] Manipulator 5 comprises a rotator 51 (rotating cylinder), a robotic arm 52, and a sponge suction cup 53. Rotator 51 is fixed to the XYZ triaxial shift mechanism 4. The upper end of robotic arm 52 is connected to the output of rotator 51, while the lower end of robotic arm 52 is fixedly connected to sponge suction cup 53. Movement in the Y direction is achieved through the meshing of the gear of a 0.75kW servo motor mounted on the Z-axis mechanism 43 and the rack on the Y-axis mechanism 42. Two manipulators 5, using the negative pressure generated by a vacuum pump, can suck up two finished bags of the same specification at a time for mobile packing.

[0027] The infeed conveyor 2 is equipped with a rising and falling bag stop 21 at the rear end of each bag-infeed station. Finished bag position detectors 22 are located on either side of the bag stop 21. The infeed conveyor 2 is a belt conveyor with two 700mm long belts, capable of positioning two finished bags on the conveyor at a time. The bag stop 21 consists of a cylinder, a baffle, and a slide rail. The finished bag position detector 22 uses a through-light to check whether the finished bag is in place on the belt conveyor. Once in place, the bag stop 21 rises to hold the bag in place.

[0028] The bag-feeding conveyor 2 is equipped with a bag-feeding adjustment mechanism 6, which includes two bag-feeding guide baffles 61, a first micromotor 62, and two first screws 63. The two first screws 63 are parallel to each other and rotatably connected above the two ends of the bag-feeding conveyor 2 at intervals. The first micromotor 62 synchronously drives the two first screws 63 to rotate in the same direction. The two ends of the two first screws 63 have screw portions with opposite spiral directions. The two bag-feeding guide baffles 61 are located on either side of the bag-feeding conveyor 2. The tops of the two bag-feeding guide baffles 61 are threadedly connected to the corresponding threaded portions on the two first screws 63 via two nut seats. The first micromotor 62 drives the first screw 63 to rotate, adjusting the distance between the two bag-feeding guide baffles 61 to meet the width of finished bags of various specifications, thereby guiding the finished bags.

[0029] The box-feeding conveyor 3 is a roller conveyor. Each box-feeding station is equipped with a lifting plate 31 at the rear end. Carton arrival detectors 32 are located on both sides of the plate 31. The carton arrival detectors 32 detect whether there is a carton at the corresponding position. If a carton is detected, the plate 31 will rise to locate the position.

[0030] The box feeding conveyor 3 is provided with a box feeding adjustment mechanism 7, which includes two support frames 71, a second micro motor 72 and two second screw rods 73; the two second screw rods 73 are connected to the top of the two ends of the box feeding conveyor 3 and rotate at intervals, and the second micro motor 72 synchronously drives the two second screw rods 73 to rotate in the same direction, and both ends of the two second screw rods 73 have threaded portions with opposite spiral directions. The two support frames 71 are respectively located on both sides of the bag feeding conveyor 2, and the bottoms of the two support frames 71 are respectively threadedly connected to the threaded portions on the corresponding sides of the two second screw rods 73 through two nut seats; the lower parts of the opposite sides of the two support frames 71 are respectively fixed with mutually parallel The tops of the two support frames 71 are connected to a lifting frame 75 via vertical guide rail slider structures. Each lifting frame 75 is driven by a corresponding lifting driver 710. The top of one of the lifting frames 75 is connected to a mobile frame 76 via a transverse guide rail slider structure. This mobile frame 76 is driven by a shift driver 711 to move parallel to the conveying direction of the infeed conveyor 3. The mobile frame 76 and the top of the other support frame 71 are rotatably connected to rotating rods 77, which are driven to rotate by corresponding rotators 78. Carton paddles 79 are fixed to the two rotating rods 77 corresponding to the two infeed stations. The lifting driver 710 and the shift driver 711 are both electric push rods, and the rotator 78 is a rotary cylinder.

[0031] Depending on the size of the carton, a second micromotor 72 drives two second screws 73 to rotate synchronously and in the same direction, adjusting the position of the infeed guide baffle 74 to guide the carton. The carton paddles are adjusted in height by a lift actuator 710, and the movable paddles are positioned by a shift actuator 711 to ensure that each paddle is correctly positioned on the flaps on both sides of the carton. The rotator 78 rotates the paddles, opening the flaps on the corresponding sides of the carton, facilitating the transfer of finished packages into the carton.

[0032] The utility model is designed with two workstations for packing, and the packing speed reaches 1000 packages per hour, which greatly improves the packing efficiency.
