[0003] The utility model discloses a kind of bag stacking conveying mechanism, to overcome the defects of prior art, by suction nozzle being connected with linkage mechanism, so that suction nozzle can be vertically lifted and also can make longitudinal sliding, it is convenient for bag delivery.

[0004] The technical solution of this utility model: A bag stacking and conveying mechanism includes a stacking area and a delivery area located one station after the stacking area. The stacking area has a conveyor belt, and the delivery area has a conveyor belt and delivery wheels located above the conveyor belt and cooperating with it to clamp the bags. A bag picker is provided at the end of the stacking area. The bag picker includes a suction nozzle and a linkage mechanism that drives the suction nozzle to reciprocate between the end of the stacking area and the delivery area. The linkage mechanism has a track plate, a movable seat, and a linkage rod. The linkage rod is vertically slidably mounted on the movable seat, and the movable seat is longitudinally slidably mounted on the track plate. The track plate has a track groove, which has a vertical groove section and a longitudinal groove section. The front end of the longitudinal groove section is connected to the upper end of the vertical groove section by an arc transition. A moving wheel is provided in the track groove, which is driven by a motor through a swing arm. One end of the swing arm is connected to the output shaft of the motor, and the other end of the swing arm is rotatably sleeved on the moving wheel and has a sliding groove for the moving wheel to slide relative to it. The upper end of the linkage rod is connected to the moving wheel, and the lower end is used for the suction nozzle installation. The moving wheel slides in the vertical groove section, thereby driving the linkage rod to rise and fall vertically. After the moving wheel enters the longitudinal groove section from the vertical groove section, it drives the linkage rod to slide longitudinally.

[0005] By adopting the above technical solution, the suction nozzle is connected to the linkage mechanism, enabling the nozzle to both move vertically up and down and slide longitudinally, facilitating bag delivery. In use, the suction nozzle is positioned above the bag. First, the motor rotates forward, driving the moving wheel to slide downwards in the vertical groove section. This causes the linkage rod to move the suction nozzle downwards to above a stack of bags and hold them in place. Then, the motor reverses, driving the moving wheel to slide upwards in the vertical groove section. This causes the linkage rod to move the suction nozzle upwards to a certain position. Afterwards, the moving wheel moves from the vertical groove section into the longitudinal groove section, where it slides backwards. This causes the linkage rod to move the upward-moving suction nozzle backwards, thus delivering the bag between the delivery wheel and the conveyor belt. Then, the motor rotates forward, driving the moving wheel to slide forwards in the longitudinal groove section, and then back into the vertical groove section to slide downwards, for the next cycle of feeding. This continuous back-and-forth motion achieves evenly spaced and continuous bag delivery to the delivery area.

[0006] A further feature of this invention is that a suction plate is mounted on the lower end of the linkage rod, and multiple suction nozzles and a sensor switch are distributed horizontally along the suction plate.

[0007] With the above-mentioned further settings, the multiple suction nozzles have a good suction effect on the bag, preventing it from falling off, and the sensor can also detect the location of the bag approaching the delivery area.

[0008] A further feature of this invention is that an assembly frame is provided at the end of the stacking area, and an adjustable lateral position mounting seat is installed on the assembly frame. The track plate is mounted on the mounting seat, and an air suction device connected to the suction nozzle is also provided on the mounting seat.

[0009] With the further setting, the bag picker can be adjusted in lateral position, and the bag picker is convenient to use.

[0010] The further setting of the utility model discloses: the front and rear ends of the delivery area are equipped with delivery wheels, and elastic pressing pieces are further equipped between the delivery wheels of the front and rear ends, the opening degree of the pressing piece front end and the conveying belt is greater than the opening degree of the rear end and the conveying belt, so as to press the bag on the conveying belt.

[0011] With the further setting, the bag is pressed and delivered by the delivery wheels at both ends, and the bag is pressed by the pressing piece to avoid lifting, and the opening degree of the pressing piece front end and the conveying belt is larger, so that the bag is convenient to enter.

[0012] The further setting of the utility model discloses: the belt length of the conveying belt is uniformly distributed with a plurality of convex bag pushing plates, the bag is pushed by the bag pushing plate, and the bag is conveyed to the delivery area.

[0013] With the further setting, every time a stack of bags is put in the stacking area, the corresponding bag pushing plate synchronously follows, the bag is pushed to move forward, and the conveying is convenient.

[0014] The further setting of the utility model discloses: a plurality of conveying belts are arranged in parallel on the stacking area, the bag pushing plates on each conveying belt are transversely aligned, and the plurality of conveying belts are further arranged on the lateral side of the delivery area.

[0015] With the further setting, the bag pushing plates on each conveying belt are transversely aligned and can simultaneously push the bag, so that a stack of bags is transversely aligned and avoids deviation, and the plurality of conveying belts are further arranged on the lateral side of the delivery area, so that the small bags on the side of the delivery area can be conveyed.
