Description

A box palletizing gripper

technical field

The utility model relates to mechanical equipment, in particular to a box palletizing gripper. the

Background technique

In industrial production, in order to improve handling efficiency and storage space utilization, it is often necessary to stack products, that is, to stack them neatly according to a certain order and level. When palletizing with automated equipment such as robots, different grippers must be configured according to different product types. As a widely used form of product packaging, boxes are required to be neat and dense, which puts forward high requirements for the design of the gripper. the

Existing box palletizing grippers mainly include suction cup type and clamping type. The suction cup gripper is easy to throw the product out during the movement, which is not suitable for high-speed palletizing and the energy consumption of the vacuum system is large; currently, the clamping gripper is widely used. More than two driving cylinders respectively drive the splint and the supporting fingers to realize the clamping and supporting of the box body. It is necessary to control the clamping and supporting actions separately, the cost is high, the gripper is heavy and it is not easy to move the material when discharging. The piles are placed neatly and densely, which is easy to scratch the box. the

The mounting plate is fixed on the top of the fixed side plate by screws. the

The guide rod cylinder is installed on the mounting plate. the

The working process of the utility model is as follows: when working, the mounting plate is connected with the robot through the flange on the mounting plate, the fixed side plate is the fixed baffle of the stacking box, and the stacking position is determined when the box is placed, and the fixed The baffle is fixed to the mounting plate by bolted connections. The movable side plate is installed at the output end of the guide rod cylinder, and reciprocates along the horizontal direction under the action of the guide rod cylinder, clamps the box in the handling equation, and supports the stacking box, and the control system uses the movable finger The back and forth movement in the horizontal direction realizes the clamping of the stacked box, preventing the box from slipping. After being placed at the designated position, the guide rod cylinder moves to make the supporting needle flexibly withdraw from the bottom of the box, and the box will not move randomly. the

The beneficial effects of the utility model are: the structure is simple, the number of drives and the weight of the gripper are reduced, the difficulty of control is reduced, the production cost is saved, and the economic efficiency is improved, and the box body will not move randomly during the placement process of the box body to ensure In addition, the combination of movable fingers and spring mechanism and support needles ensure that the box body will not slip. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. the

As shown in the figure, the box palletizing gripper includes a gripper device and a control system. The gripper device includes a fixed side plate 1, a mounting plate 2 and a movable clamping device, and the mounting plate 2 is fixed on the fixed side plate 1. and the top of the movable clamping device, the control system controls the movable clamping device to move back and forth in the horizontal direction at the bottom of the mounting plate 2, and the control system is connected with the movable clamping device. the

The movable clamping device includes a movable side plate 4 and a movable finger 5, and the movable finger 5 and the movable side plate 4 are connected by a guide mechanism 6 and a spring mechanism 7, and a supporting needle 8 is fixedly installed on the bottom of the movable side plate 4, and is formed by Supporting needle 8 realizes supporting of the box body; one end of guide mechanism 6 is movably installed in the middle of movable side plate 4, movable finger 5 is installed on the other end, and spring mechanism 7 is connected between movable finger 5 and movable side plate 4 , the movable finger 5 realizes the clamping of the box through the force of the spring mechanism 7 . the

The control system includes a controller, a solenoid valve and a pressure regulating valve connected to the controller. The controller controls the movement of the guide rod cylinder 3 through the solenoid valve to complete the action of clamping and releasing. The pressure regulating valve is connected with the guide rod cylinder 3 to adjust the pressure of the guide rod cylinder 3 , and the output rod of the guide rod cylinder 3 is connected with the movable side plate 4 . the
