The left and right flaps 42, 43 may secure the carton board at the bottom and the upper left and right stops 46, 47 may secure the carton board at the top, preventing the carton board from tipping over. The right baffle 43 is connected with the screw 417 through a nut 419, so that the position of the right baffle 43 can be adjusted through rotating the hand wheel 418, and the position of the right upper block 47 is adjusted through a right kidney-shaped groove on the upper cross beam 406, so as to adapt to carton boards with different widths. The middle press 48 may be aligned with the split between the face and side panels of the carton blank through the middle kidney slot of the upper cross member 406 to facilitate subsequent folding. Because the included angle between the upper box frame 41 and the horizontal plane is 30 degrees, the rear pressing plate 45 is arranged on the two longitudinal guide rods 415 of the upper box frame 41 through the vertical plate 450 and the linear bearing 451, and the feeding can be automatically finished by directly sliding the cartons and the rear pressing plate 45 downwards along the longitudinal guide rods 415 under the dead weight of the cartons and the rear pressing plate 45 without adding any driving mechanism. When a carton board is placed in the rear pressing plate 45, the carton board is fixed, and after the carton board is sucked away by the vacuum box sucking mechanism, the carton board slides down due to the gravity of the carton board and the rear pressing plate 45 to automatically complete carton feeding, so that the feeding position of the carton is ensured to be proper every time.
The bottom case sealer 5 comprises a frame 50, two bottom cover guide pipes 51, a fixing frame 52 and a tape sticking machine 53; the rack 50 comprises a base 501 and a seesaw 502 arranged at the upper end of the front part of the base 501; two bottom cover guide tubes 51 are connected to the base 501 and symmetrically located at the left and right sides of the seesaw 502; the fixed frame 52 is arranged at the rear part of the base 501; the taping machine 53 is mounted in a holder 52 (see fig. 5 and 5 a). The taping machine 53 is provided with front and rear rollers, a spring, a saw tooth member, a crank and the like.
The main function of the bottom box sealing machine 5 is to seal the carton with the front and rear covers and the side covers folded by using adhesive tapes. After the carton is placed on the upper rocker 502, the robot compacts and moves the carton so that the front, rear, and side covers are folded by the bottom cover guide tube 51. When the carton with the front cover and the rear cover folded with the side covers moves forward under the action of friction force of the belt, the front roller is firmly pressed down by the carton due to compaction of a robot, so that the front roller rotates, and meanwhile, the top end of the adhesive tape of the front roller is stuck to the carton. The carton continues to move forward, the front roller drives the rear roller through the crank, the front roller and the rear roller rotate simultaneously, and the spring connected with the rear roller is stretched. The carton is advanced while depressing the saw tooth links, causing the springs connected to the saw tooth links to be stretched. When the carton crosses the serrated link, the serrated link rotates upward under the action of the spring, and the serrated rotates with the serrated link first due to the action of the small spring, so that the adhesive tape can be cut. When the carton crosses the rear roller, the spring connected with the rear roller recovers the original shape and contracts, so that the rear roller is driven to rotate upwards, the rear half part of the adhesive tape at the bottom of the carton is compacted, meanwhile, the rear roller drives the front roller to rotate through the crank, and therefore after the carton passes through the tape pasting machine 53 and the adhesive tape is sealed, the whole tape pasting machine 53 can automatically restore.
The robot unpacking, boxing and stacking all-in-one machine has the working process that: the robot and the upper box machine cooperate to take boxes → the gripper of the robot folds → the robot and the bottom box sealing machine cooperate to seal boxes at the bottom → the gripper of the robot packs boxes → the box sealing machine seals boxes → a transition line arrives at the stacking and grabbing station → the gripper of the robot is stacked.
The specific work flow is as follows: the products 300 reach the product positioning and grabbing station 22 through the product arranging station 21 by the product conveying line 2 to wait for boxing, meanwhile, the carton opening and stacking suction cups 101 on the grippers 100 of the robot 10 suck the carton boards 200 (see fig. 6) on the carton loader 4, the cartons 200 are taken out by controlling the walking path, the panels of the carton boards 200 are sucked by the carton opening and stacking suction cups 101 on the grippers 100, the lower swing arm 185 rotates 90 degrees under the control of the lower air cylinder 183 to fold the side plates of the carton boards 200 (see fig. 7) for 90 degrees to form cartons, and then the upper swing arm 184 rotates 90 degrees under the control of the upper air cylinder 182 to enable the folding fixing suction cups 103 to suck the side plates of the cartons 200 to be fixedly folded. After the robot folds, the walking path is controlled by a robot program, when the robot passes through the bottom box sealing machine 5, the bottom cover plate of the paper box 200 is folded and sealed, and then the paper box 200 is placed at the boxing station 34. The box loading suction cups 102 on the control grippers 100 suck the products 300 on the product positioning and grabbing stations 22, the robots control the postures of the grippers to place the products 300 into the cartons 200 (see fig. 8), after the cartons 200 are filled, the carton sealing machine 6 on the front section transition line 31 folds and seals the top cover plates of the cartons 200, then the cartons 200 which are sealed sequentially pass through the transverse transition line 32 and the rear section transition line 33 to reach the stacking and grabbing stations 35, the box opening and piling suction cups 101 on the robot grippers 100 suck the cartons 200 and pile the cartons 200 on pallets of the stacking stations 7 (see fig. 9), when the boxes on the pallets reach a certain height, the cartons are conveyed to the discharging stations 8, and finally the pallets are conveyed together by the forklift. The pallet feeder 9 then feeds the pallet to the vacating palletizing station 7.
