Referring to fig. 4 to 10, the box opening component 2 includes a swing component 21, a brake component 22, and a translation mechanism 24 for driving the brake component 21 and the swing component 22 to translate. And the translation mechanism moves the braking assembly and the swinging assembly to the box opening station when the box opening component performs box opening action.

The swing assembly 21 includes a first fixing frame 214, a swing arm pivotally connected to the first fixing frame, a first suction cup 2111 disposed on the swing arm, and a first driver 213 for driving the swing arm to swing. The first actuator may be a first cylinder, or an electric cylinder.

It can be appreciated that the first suction cups 2111 can be provided in a greater number and with a greater range of distribution due to the greater area of the carton sheets. As shown in fig. 7 to 9, in the present embodiment, the swing arm includes a beam 212 and two first suction pad mounting columns 211 provided side by side on the beam, and the first suction pad 2111 is provided on the first suction pad mounting column 211.

If the size of the carton sheet is changed, the relative position between the two first suction cup mounting columns needs to be adjusted, so a transverse adjusting structure for adjusting the relative position between the two first suction cup mounting columns is arranged between the first suction cup mounting column 211 and the cross beam 212. The transverse adjusting structure comprises an adjusting slider 2121 movably arranged on the cross beam 212 and an adjusting pin 2113 arranged on the first suction disc mounting upright, the adjusting slider 2121 is fixed with the first suction disc mounting upright, a pin hole is formed in the adjusting slider, a lock hole is formed in the cross beam, and the adjusting pin movably penetrates through the adjusting hole and then is fixed with the lock hole, so that the adjusting slider and the cross beam are locked.

The cross beam is provided with adjusting scales 2122, the first suction cup mounting upright post 211 is connected with a scale pointer 2117, and the position adjusting process and the position adjusting result of the first suction cup mounting upright post can be conveniently and visually known.

Further, a first suction pad driving cylinder 2112 is provided on the swing arm for driving the first suction pad to move horizontally, thereby adjusting the position of the first suction pad 2111. The first suction plate 2111 is close to the output end of the carton sheet stepping conveying mechanism 11 in the carton sheet storage component 1 through the translation mechanism 24, but the first suction plate 2111 may still be at a certain distance from the carton sheet, and the fine adjustment needs to be realized through the first suction plate driving air cylinder 2112. Eventually the first suction cup 2111 comes into close proximity with the front of the carton sheet and the first suction cup 2111 can fully suck the carton sheet.

The brake assembly 22 includes a second fixing frame, a brake arm 221 rotatably connected to the second fixing frame, a second suction cup 2211 disposed on the brake arm, a second driver for driving the brake arm to horizontally slide on the second fixing frame, and a third driver for driving the brake arm to swing. The second driver comprises a second cylinder 225, a guide block 2251 and a guide shaft 2252, the guide block is provided with a guide hole, the guide shaft 2252 is in guide fit with the guide hole, the brake arm 221 is rotatably connected to the guide shaft, and the second cylinder drives the guide shaft to axially move along the guide hole and drives the brake arm to axially slide. Since the brake arm 221 is rotatably connected to the guide shaft, the third driver may drive the brake arm 221 to swing in a direction parallel to the carton sheet, so that the second suction pad 2211 may move to the back side of the carton sheet after the first suction pad sucks the front side of the carton sheet. Then, the second suction cup 2211 is brought close to the carton sheet by axially sliding the stopper arm 221, so that the carton sheet can be sucked and fixed.

Further, the guide block 2251 is provided with a U-shaped groove, guide holes are formed on two opposite side walls of the U-shaped groove, the braking arm 221 is provided with a U-shaped portion, the U-shaped portion is disposed in the U-shaped groove, the two side walls are rotatably connected with the guide shaft 2252, and the guide shaft is connected with a hoop between the two side walls of the U-shaped portion.

Therefore, the lifting cylinder 223 drives the lifting slider 2231 to slide along the lifting guide rail, and the lifting link 224 drives the brake arm 221 to swing around the guide shaft, so that the second suction cup 2211 can move to the back of the carton sheet. Because the lifting link 224 moves along with the brake arm 221, but the lifting column is fixed, considering that the translation distance of the brake arm 221 is small, ball hinges can be arranged at both ends of the lifting link 224, so that the lifting link 224 can be allowed to swing at a certain angle, and the normal function of the hinged relationship between the lifting link 224 and the lifting column and the brake arm is still ensured.

The specific working process of the unpacking component 2 is as follows: first, the translation mechanism 24 drives the brake assembly 21 and the swing assembly 22 to translate, close to the output end of the carton sheet step-by-step conveying mechanism 11 in the carton sheet storage component 1, and the first suction tray 2111 faces the front face of the carton sheet. At this time, the first suction tray functions to suck one of the width-direction side surfaces of the carton sheet. The translating mechanism then translates the brake assembly 21 and the swing assembly 22 to the opening station, while the third actuator simultaneously swings the brake arm 221 such that the second suction pad 2211 on the brake arm is parallel to the carton sheet and is on the back side of the carton sheet. Next, the second actuator drives the brake arm 221 to horizontally slide, so that the second suction pad 2211 on the brake arm approaches and sucks the carton sheet, thereby fixing one of the longitudinal sides of the carton sheet. And finally, the first driver drives the swing arm to swing, so that the carton sheets are pulled to be opened, and the carton opening is realized. After the carton opening is completed, the first suction cup 2111 and the second suction cup 2211 release the carton, then the translation mechanism 24 drives the brake assembly 21 and the swing assembly 22 to translate towards the carton sheet storage component 1, and in the process of moving to be close to the output end of the carton sheet stepping conveying mechanism 11 in the carton sheet storage component 1, the brake arm of the brake assembly 21 and the swing arm of the swing assembly 22 can be reset, so that the next carton opening operation can be immediately performed after the brake assembly 21 and the swing assembly 22 are moved to the right position. Therefore, the unpacking operation can be continuously performed.
