Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly to a vertical box-opening mechanism. Background Art

[0002] In the packaging industry, corrugated cartons are widely used, and carton box-opening (expanding a flat box blank into a box body) has become an essential process. Before the application of automated equipment, most carton box-opening was done manually, with low efficiency and poor forming effect. After automation transformation, the box-opening equipment generally includes a box blank storage part, a box-opening part, and a packing and sealing part. Most box-opening equipment has a 90° feeding method, that is, the box blank storage part is arranged at a right angle to the box-opening part and the packing and sealing part. During operation, according to the relationship between the carton size and the printed content, first, the paper blank is pulled out from the box blank storage part by a suction cup, and the box blank is fed from the left or right side of the box-opening machine. Then, in the box-opening part, the carton is squeezed into a square shape by a guide plate, and then the bottom folding flap is pushed out. Finally, the packing and sealing part uses tape to seal the bottom to complete the box output.

[0003] This kind of 90° box-opening equipment occupies a large space horizontally, and large spaces need to be reserved on both sides of the passage, which is not suitable for the packaging line in a narrow and long workshop. The box-opening and packing and sealing are integrated and used, and a large space also needs to be reserved, having such defects and deficiencies. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a vertical box-opening mechanism that adopts a linear feeding method, has a compact structure and small volume, can be matched and integrated into existing equipment, is suitable for the packaging line in a narrow and long workshop, has a regular carton box-opening and forming, and a high degree of automation.

[0005] The present invention uses a servo and a module as the power source and adopts a vertical box-opening structure in a linear direction. This structure can connect the box blank storage part and the packing and sealing part, and through the reciprocating rotation of the cylinder and the vacuum suction cup in sequence, the carton is opened into a square shape. The storage part, the box-opening part, and the packing and sealing part are arranged in a linear layout, with a compact structure and small space occupation. The present invention is particularly suitable for small-sized integrated equipment.

[0006] A vertical box-opening mechanism of the present invention includes a carton short-side vacuum generator, a carton short-side suction cup, a folded short-page component, a carton long-side vacuum generator, a carton long-side suction cup, a module, a drag chain, a servo motor, a rotating shaft component, a sliding table, a carton short-side arm, and a carton long-side arm. The carton short-side vacuum generator, the carton short-side suction cup, the folded short-page component, the carton long-side vacuum generator, the carton long-side suction cup, and the rotating shaft component constitute a box-opening functional structure. The module is fixed on the overall frame, and the module is provided with a linear guide rail. The linear guide rail is located between the blank storage part and the packing and sealing part. The sliding table is slidably installed on the linear guide rail. The servo motor provides power for the sliding table to drive the sliding table to connect the blank storage part and the packing and sealing part. The rotating shaft component is installed on the sliding table. Both the carton short-side arm and the carton long-side arm are installed on the rotating shaft component. The short-side suction cup rotating cylinder and the long-side suction cup rotating cylinder are both installed on the sliding table. The short-side suction cup rotating cylinder and the long-side suction cup rotating cylinder respectively drive the carton short-side arm and the carton long-side arm to open the carton blank. The carton short-side vacuum generator and the carton short-side suction cup are installed on the carton short-side arm. The carton long-side vacuum generator and the carton long-side suction cup are installed on the carton long-side arm. The air pipe and the wire provide positive pressure gas and signals for the carton short-side vacuum generator and the carton long-side vacuum generator through the drag chain. The folded short-page component is fixed on the carton short-side arm. Initially, the carton short-side suction cup is parallel and aligned with the short side of the carton blank. The long-side suction cup rotating cylinder retracts and drives the carton long-side arm and the carton long-side suction cup to rotate 90° through the rotating shaft component, so that the carton long-side suction cup is perpendicular to the carton short-side suction cup. The servo motor drives the sliding table to move along the linear guide rail of the module, so that the sliding table drives the box-opening functional component to move to the blank storage part. The carton short-side vacuum generator generates vacuum to make the carton short-side suction cup adsorb the short side of the carton blank. The servo motor drives the sliding table to move along the linear guide rail of the module, pulls out the carton blank a certain distance. The short-side suction cup rotating cylinder contracts and drives the carton short-side arm and the carton short-side suction cup to rotate and approach the carton long-side suction cup through the rotating shaft component, and turns and presses the long side of the other side of the carton blank adsorbed by the carton short-side suction cup on the carton long-side suction cup. The carton long-side vacuum generator generates vacuum, and the long side of the carton blank is adsorbed and fixed by the carton long-side suction cup. The long-side suction cup rotating cylinder extends and drives the carton long-side arm and the carton long-side suction cup to rotate 90° in the reverse direction through the rotating shaft component, so as to open the flat carton into a square shape. The folded short-page component extends to fold the short page at the box opening of the carton blank. The servo motor drives the sliding table to continue to move along the linear guide rail of the module, and sends the opened carton into the packing and sealing part to realize linear feeding. Compared with the box-opening mechanism with 90° feeding, it is connected with the storage box and the packing and sealing part through the module, is linear, has a compact structure and a small volume, is suitable for automatic integration, does not need to reserve a large space on both sides of the channel, is suitable for the packaging line in a narrow and long workshop, the box opening and the packing and sealing are arranged in a straight line and separated, does not need to reserve a large space for the space, has a high degree of automation, a high working efficiency, can be matched and integrated into the existing equipment, the carton is opened and formed neatly, and has good practicability.

The long-side suction cup rotation cylinder 11 extends and drives the long-side arm of the carton and the long-side suction cup 5 of the carton to rotate reversely 90° through the rotating shaft assembly 9, so that the flat carton is opened into a square. Finally, the piston rod of the cylinder 25 extends, pushing the upper end of the connecting arm 26 upward, so that the connecting arm 26 drives the pressing plate 27 to rotate and extend away from the side wall of the first vertical arm 21, so that the pressing plate 27 folds the short page into the box opening. The servo motor 8 drives the slide table 12 to continue to move along the linear guide rail of the module 6, and sends the opened carton into the packing and sealing part, realizing linear feeding.
