Description

Technical Field

[0001] The utility model relates to the technical field of box coding machines, in particular to an automatic box coding machine for packaging boxes. Background Art

[0002] The top and bottom lid packaging box includes a top box and a bottom box. After the top box and the bottom box are produced respectively, the top box is buckled on the outside of the bottom box, and then transported through the conveyor line to the box stacking machine for stacking.

[0003] After the lid packaging boxes on the conveyor line are conveyed to the box stacking machine, they need to be flipped 90 degrees, that is, converted from a flat state to an upright state, and then stacked and pushed out by the box stacking machine before entering the subsequent packaging process.

[0004] However, when flipping the top and bottom lid packaging boxes, mechanical structures are mostly used, such as cylinder clamping to drive the flipping, etc., which requires additional power, thereby increasing the failure points and operation control process, bringing inconvenience to production.

Under the guidance of the upper inclined plate and the lower inclined plate, the packaging box is converted from a flat state to an upright state. At this time, the packaging box is located between the two arms, and the packaging box is pushed to the stacking table by the discharging structure. After the packaging boxes are stacked to a predetermined number on the stacking table, the pushing structure pushes out the stacked packaging boxes to complete the stacking.

[0012] The guide structure includes guide frames fixedly mounted on both sides of the conveyor belt support, guide plates fixedly mounted on the guide frames, and ends of the two guide plates close to the feeding end of the conveyor belt are bent and extended outward.

[0013] Among them, the clamping and limiting structure includes a clamping cylinder support fixedly installed on both sides of the conveyor belt bracket, and a clamping cylinder is fixedly installed on the clamping cylinder support. The cylinder rods of the two clamping cylinders are arranged opposite to each other and are fixedly installed with clamping plates, and a photoelectric switch is installed on one of the clamping plates.

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0025] like Figure 1-4 As shown, an automatic box stacking machine for packaging boxes includes a conveyor belt bracket 1 and a stacking platform 2, a conveyor belt 3 is installed on the conveyor belt bracket, the stacking platform is arranged on the unloading end side of the conveyor belt, and a guide structure and a clamping limit structure are installed on the conveyor belt bracket;

[0026] The unloading end of the conveyor belt is provided with a turning structure 4;

[0027] The turnover structure comprises two spaced apart supporting arms 5, which are fixedly mounted on the stacking platform, an upper inclined plate 6 and a lower inclined plate 7 are fixed between the two supporting arms, the lower inclined plate is arranged close to the unloading end of the conveyor belt, the upper inclined plate is arranged parallel to the lower inclined plate, and an inclined turnover channel is formed between the upper inclined plate and the lower inclined plate;

[0028] A baffle 8 is fixed between the lower end of the upper inclined plate and the two supporting arms, and the baffle is arranged opposite to the lower inclined plate; a discharging structure is also arranged on one side of the stacking table, and a pushing structure is installed on the stacking table.

[0029] In this way, the packaging box 10 after buckling is conveyed to the conveyor belt. Since the previous process of the conveyor belt is the buckling process of the packaging box, the packaging boxes loaded onto the conveyor belt are arranged at intervals. The conveyor belt drives the packaging box to move, the guide structure guides the packaging box, and the clamping and limiting structure clamps and limits the packaging box. The packaging box falls to the flipping channel through the unloading end of the conveyor belt. Under the guiding action of the upper inclined plate and the lower inclined plate, the packaging box is converted from a flat state to an upright state. At this time, the packaging box is located between the two arms, and the packaging box is pushed to the stacking table by the discharging structure. After the predetermined number of packaging boxes are stacked on the stacking table, the pushing structure pushes out the stacked packaging boxes to complete the stacking.

[0030] During implementation, the guide structure includes guide frames 11 fixedly mounted on both sides of the conveyor belt support, and guide plates 12 are fixedly mounted on the guide frames, and the ends of the two guide plates close to the feeding end of the conveyor belt are bent and extended outwards, so as to guide the packaging box.

[0031] During implementation, the clamping and limiting structure includes a clamping cylinder support fixedly mounted on both sides of the conveyor belt support, on which a clamping cylinder 13 is fixedly mounted, and the cylinder rods of the two clamping cylinders are arranged opposite to each other and fixedly mounted with a clamping plate 14, one of which is mounted with a photoelectric switch 15. A rubber pad is fixed on the surface of the clamping plate to avoid abrasion on the surface of the packaging box. When the photoelectric switch detects that the packaging box has moved into position, the cylinder rod of the clamping cylinder extends out, and the packaging box is clamped and limited by the clamping plate. After the packaging box moves to the flip structure, the discharging cylinder pushes the packaging box to move to the stacking table, and the clamping and limiting structure releases the clamping and limiting of the packaging box.

[0032] During implementation, the two arms extend toward one side of the conveyor belt to form a side plate 16. Conduct wires to the packaging boxes entering the overturning channel.

[0033] During implementation, the discharging structure includes a discharging bracket 17, on which a discharging cylinder 18 is fixedly mounted, and a cylinder rod of the discharging cylinder is fixedly mounted with a discharging plate 19. The discharging cylinder drives the discharging plate to move and discharge the packaging box.

[0034] During implementation, the pushing structure includes two pushing cylinder seats 21 fixedly mounted on the stacking table, on which a pushing cylinder 22 is fixedly mounted, and the cylinder rods of the two pushing cylinders are fixedly connected to a pushing plate 23, and two sides of the stacking table are fixedly mounted with a limiting plate 24. The pushing cylinder drives the pushing plate to move, and pushes the stacked packaging boxes to one side.

[0035] During implementation, the height of the limit plate is smaller than the height of the packaging box in an upright state, so that the mechanical arm of the packaging station can clamp the stacked packaging boxes to arrive at the packaging station for packaging.

[0036] During implementation, a top plate 25 is further provided on the stacking table, one end of which is fixedly connected to the support arm, and the other end of which is fixedly connected to the limiting plate through a connecting rod, so as to facilitate limiting the packaging box.

[0037] Specifically, it also includes a PLC controller, which receives the signal of the photoelectric switch and controls the actions of the conveyor belt, the clamping cylinder, the discharging cylinder and the pushing cylinder. The automatic box stacking machine is fixed on the workbench of the frame as a whole to form a station of the box production line.
