Description

Technical Field

[0001] The invention relates to the technical field of packaging box transfer and stacking, and in particular to an automatic transfer and stacking device for paper packaging boxes. Background Art

[0002] A carton refers to a three-dimensional container made of cardboard, which is often used to package various items to prevent them from being damaged by foreign objects during transportation or storage. In particular, in various large warehouses, cartons of a certain specification are usually used to package the same type of items. The packaged items are then stacked on pallets in sequence by robotic arms, and forklifts, gantry cranes and other equipment are used to transport the items and pallets as a whole to the corresponding shelves, so as to improve space utilization while protecting the items from external damage when they are stored.

[0003] At present, when paper packaging boxes are transported to the stacking position by conveying machinery for stacking, they are usually clamped on the outside of the paper packaging boxes by a transfer robot arm in cooperation with a clamping fixture. Then, the clamping fixture clamps the paper packaging boxes with two clamping plates under the drive of a cylinder. After being clamped, the paper packaging boxes will be transported by the robot arm to the pallet at the stacking position for stacking operation. Since the hardness of paper packaging boxes is relatively low, the robot arm and the clamp cannot exert a large force on the paper packaging boxes when clamping them. Otherwise, the paper packaging boxes may be deformed or damaged and fail to protect the items. A small clamping force may cause the paper packaging boxes to slip when being transferred from the conveyor belt to the pallet. In order to safely clamp paper packaging boxes, rubber pads are usually set on the surface of the clamp's plywood for cushioning. However, the cushioning effect of this hard pad is limited, which makes the paper packaging boxes easily damaged after clamping. In addition, the paper packaging boxes are clamped by only two plywoods, so there are fewer clamping force points for the paper packaging boxes. When the paper packaging boxes are loaded with heavy objects for transportation, the paper packaging boxes are easy to slide down in the clamp or even fall out of the clamp, thereby failing to ensure the low-damage and safe transportation and stacking of the paper packaging boxes. For this reason, we propose an automatic transportation and stacking device for paper packaging boxes. Summary of the invention

[0004] The main purpose of the present invention is to provide an automatic transfer and stacking device for paper packaging boxes. The present invention fully considers the transfer safety of paper packaging boxes. For example, the rough friction surface design of the rubber support strip can increase the friction and prevent the packaging box from slipping. The support strip plate of the L-shaped support foot and its inclined surface design can reduce the friction and resistance during the transfer process. At the same time, the rubber pad box with a built-in grease filling block can be highly cushioned against the outside of the paper packaging box and cooperate with the vacuum suction cup for suction and clamping. The present invention uses a four-point clamping and consignment structure to reduce the clamping force of paper packaging, thereby ensuring the low-damage and safe transfer and stacking of paper packaging boxes, which can effectively solve the problems in the background technology.

[0009] The cam is secured to the rear of the lever and is secured to the rear of the lever by a spring which secures the lever to the rear of the lever with a spring which is secured to the lever by a spring which is secured to the lever's rear end.

When the transfer robot arm needs to clamp the paper packaging box for transfer, the main clamping mechanism cooperates with the suction mechanism to clamp the paper packaging box oppositely and cooperates with the vacuum suction cup to perform a stable box clamping operation, and then the box supporting mechanism can hold down the raised paper packaging box, and cooperate with the light push of the supporting mechanism to realize the transfer actions of clamping, adsorbing, pushing and supporting the paper packaging box, which greatly improves the transfer efficiency and automation level, and ensures that the transfer robot arm can stably clamp and safely transfer and stack.

Then the electric side push rod 41 can provide driving force for the L-shaped connecting platform 42 and the vertical support plate 43, so that the vertical support plate 43 can be supported on the outside of the paper packaging box through the rubber support strip 45, and the rubber support strip 45 with a vertical hole 46 has an inwardly retracted deformation position, which improves the cushioning performance of the rubber support strip 45 against the outside of the paper packaging box, thereby realizing the lateral push of the paper packaging box; The operation process of the automatic transfer and stacking device for paper packaging boxes of the present invention is as follows: When the paper packaging box loaded with goods is transported to the vicinity of the transfer robot arm 1 by the conveyor, the transfer robot arm 1 brings the force-bearing plate 19 under the connecting frame 5 close to the top of the paper packaging, and then the transfer robot arm 1 descends with the force-bearing plate 19, so that the main clamping plate 16 under the force-bearing plate 19 and the vertical support plate 43 of the supporting mechanism 9 are outside the paper packaging box, and then the electric main push rod 15 drives the main clamping plate 16 to approach the two sides of the paper packaging box, so that the vacuum suction cup 31 and the rubber pad box 26 of the suction mechanism 7 contact the two sides of the paper packaging box. After the vacuum suction cup 31 is sucked on the outside of the paper packaging box, the rubber pad box 26 can clamp the paper packaging box against each other, and then the transfer robot arm 1 rises, so that the paper packaging box leaves the conveyor surface. At this time, the electric lower push rod 35 of the box supporting mechanism 8 lowers the L-shaped support plate 36, and then the electric push inner push rod 37 at the L-shaped support plate 36 can push the L-shaped support foot 38 to the bottom of the paper packaging box. Under the upward drive of the electric lower push rod 35, the L-shaped support foot 3 8 can support the paper packaging box that is sucked and clamped. At this time, the electric side push rod 41 of the supporting mechanism 9 can push the vertical support plate 43, and the vertical floor 43 lightly presses the outer side of the paper packaging box with the rough friction surface 47 of the rubber support strip 45 to ensure that the paper packaging box is firmly clamped by the suction mechanism 7 and the box supporting mechanism 8. At this time, the paper packaging box can be transferred to the top of the pallet for lowering and placement. During the descent of the paper packaging box, the vertical support plate 43 can leave the paper packaging box, and then the L-shaped support foot 38 leaves the bottom of the paper packaging box and rises. After the paper packaging box completely falls on the surface of the pallet, the main splint 16 can leave the paper packaging box with its back facing away, and at the same time, the vacuum suction cup 31 at the inner splint 24 can release the paper packaging box, thereby completing the transfer of the paper packaging box, and then the transfer robot arm 1 can continue the above steps to continuously pick up the paper packaging box on the surface of the paper packaging box transfer conveyor for transfer and stacking operations. All kinds of push rods in the present invention can adopt common electric push rods on the market.
