Description

Technical Field

[0001] The utility model relates to the technical field of material feeding, in particular to a material stacking and feeding mechanism. Background Art

[0002] The packaging materials used to package products are usually stacked neatly, and then the packaging materials are used to package the products. Common product packaging includes packaging boxes, which are usually formed by folding packaging materials such as packaging cardboard in a specific shape. The packaging cardboard will increase the space occupied by the packaging materials during transportation, storage, and use by neatly stacking. In traditional packaging processes, manual labor is usually used to fold the packaging cardboard into packaging boxes and package the products. With the widespread promotion of industrial automation, automatic packaging equipment is gradually being used to replace manual labor. However, since the stacking height or position of packaging materials such as packaging cardboard changes at any time as the packaging is consumed, there is a problem of difficulty in positioning the packaging materials during the process of automatic grasping and loading of packaging materials, which affects the efficiency of product packaging.

[0003] Based on the above situation, the Chinese patent with announcement number CN215755159U discloses a loading device for packaging boxes, including: a main frame, a suction cup grabbing assembly, and a claw grabbing assembly. The suction cup grabbing assembly is used to suck the packaging box to be printed with a pattern, and the claw grabbing assembly is used to grab the packaging box on the suction cup grabbing assembly. The suction cup grabbing assembly is fixed on the main frame, and the claw grabbing assembly is set corresponding to the suction cup grabbing assembly. The above loading device can replace manual loading of packaging materials, and the packaging materials are transported to the working space of the suction cup grabbing assembly and the claw grabbing assembly through the feeding conveying assembly to realize packaging. The material is positioned before loading, and the suction cup grabbing component grabs the packaging material to the set height and then grabs it to the next process through the claw grabbing component, thereby realizing the loading operation of the packaging material. However, the packaging material is conveyed one by one through the feeding conveying component. It is necessary to ensure that the packaging material has accurately arrived at the set position and the posture is accurate to avoid the suction cup grabbing component or the claw grabbing component having difficulty in grabbing the packaging material stably. Therefore, it is usually necessary to set a certain delay time for the suction cup grabbing component and wait until the packaging material is completely positioned before grabbing the packaging material, which can easily affect the loading efficiency of the packaging material. Therefore, there is still room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0021] The following describes the implementation of the present invention in conjunction with the accompanying drawings and relevant embodiments. The implementation of the present invention is not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0022] like Figure 1-3As shown, a material stacking and loading mechanism includes a fixed bracket 1, a stacking rack 2, and a loading robotic arm 3. The stacking rack 2 and the loading robotic arm 3 are both arranged on one side of the fixed bracket 1. A material trough 21 is provided on the surface of the stacking rack 2, and a loading port 22 facing the loading robotic arm 3 is provided at the bottom of the material trough 21, and a plurality of support blocks 23 are provided on the edge of the loading port 22; the loading robotic arm 3 includes the following structure, a first rotating shaft 31 and a second rotating shaft 32 whose fixed ends are fixedly connected to the fixed bracket 1, the movable end of the first rotating shaft 31 is movably connected to a height swing arm 33 through a shaft, and the end of the height swing arm 33 is movably connected to a loading swing arm 34 through a shaft, one end of the loading swing arm 34 is provided with a loading suction cup 35, and the other end is movably connected to an angle swing arm 36 through a shaft, and the end of the angle swing arm 36 is movably connected to the movable end of the second rotating shaft 32 through a shaft.

[0023] The present invention is mainly used for loading neatly stacked packaging cardboards. As a common packaging material, packaging cardboards are usually stacked in layers. In the present invention, the stacking rack 2 is used to place neatly stacked packaging cardboards and neatly stack the packaging cardboards in the material trough 21. The edge of the loading port 22 supports the edge of the packaging cardboard through the support block 23 to prevent the packaging cardboards from falling from the loading port 22. The loading robot 3 sucks the packaging cardboards at the bottom of the material trough 21 one by one from the loading port 22 through the loading suction cup 35. During the process of the loading robot 3 sucking the packaging cardboards, the loading suction cup 35 will suck the position near the center of the packaging cardboard. Since the packaging cardboard can be bent, the edge of the packaging cardboard can be separated from the support block 23 by bending. The loading robot 3 is supported and thus sucked out of the material trough 21 by the loading robot arm 3 from the loading port 22. The loading robot arm 3 sucks up the packaging cardboard and moves to the next process to realize the loading operation of the packaging material. In the above process, since the packaging cardboard stacked in the material trough 21 has a certain weight, when the loading robot arm 3 sucks up the packaging cardboard at the bottom, the other packaging cards will immediately press the next packaging cardboard to the bottom of the material trough 21 under the action of gravity. Therefore, the loading robot arm 3 will always suck up the packaging cardboard at the bottom of the material trough 21, and the loading robot arm 3 only needs to position and suck up the packaging cardboard at the bottom of the material trough 21. The sucked packaging cardboard can reach the set position in a very short time through gravity, which can improve the loading efficiency.

[0024] In the feeding robot arm 3 of the present invention, the ends of the first rotating shaft 31 and the second rotating shaft 32 are both provided with motors or other driving devices for driving the rotation of their respective movable ends. The feeding suction cup 35 is connected to a vacuum pump or a compressed air source through an air pipe to generate negative pressure, thereby achieving the suction and fixation of the packaging cardboard. A conveying device for conveying the packaging cardboard to the next process is provided below the feeding robot arm 3. The working principle of the feeding robot arm 3 is as follows: the rotation of the movable end of the first rotating shaft 31 can adjust the height of the connection between the height swing arm 33 and the feeding swing arm 34. At the same time, the rotation of the movable end of the second rotating shaft 32 causes the angle swing arm 36 to rotate synchronously, which can The feeding swing arm 34 is driven to rotate with the shaft connected to the height swing arm 33 as the axis, and the direction angle of the feeding suction cup 35 at the end of the feeding swing arm 34 is adjusted. By adjusting the height and direction angle of the feeding swing arm 34, the feeding suction cup 35 at the end of the feeding swing arm 34 can be accurately moved to the feeding port 22. The negative pressure generated by the feeding suction cup 35 is used to suck and fix the packaging cardboard, and the sucked packaging cardboard is moved to the surface of the conveying device under the feeding robot arm 3, and then the negative pressure of the feeding suction cup 35 is canceled to put the packaging cardboard down. This cycle can realize the feeding operation of packaging materials such as packaging cardboard.

[0025] To sum up, the utility model accommodates neatly stacked packaging materials through the material trough 21 of the stacking rack 2, and the loading robot arm 3 sucks the packaging materials at the bottom from the loading port 22 and moves to achieve loading. The packaging materials at the bottom can always be located at the bottom of the material trough 21 under the action of gravity, so that the packaging materials can be automatically positioned. In addition, after the loading robot arm 3 absorbs and fixes the packaging materials through the loading suction cup 35, the loading swing arm 34 is moved through the linkage of the first rotating shaft 31, the height swing arm 33, the second rotating shaft 32, and the angle swing arm 36, so as to efficiently move the packaging materials to the loading position. The utility model can improve the loading efficiency of the packaging materials.

[0028] Furthermore, two or more material sensing elements 26 can be set along the thickness direction of the packaging cardboard. When all the packaging cardboard in the material trough 21 is consumed to a thickness that matches the position of one of the material sensing elements 26, it can be sensed by the material sensing element 26. Then, when the amount of packaging cardboard in the material trough 21 is small and the thickness is reduced, the material sensing element 26 can sense it and notify the operator in advance to add packaging cardboard, thereby avoiding the suspension of operation of the utility model and improving the loading efficiency.
