Flexible material conveying and correction device based on the principle of air suspension

technical field

The invention relates to an automatic conveying device, in particular to an automatic conveying device for flexible materials.

Background technique

Similar to flexible materials such as manufacturing, because the structure itself is relatively soft, the material is easily deformed during the transportation process. Therefore, it cannot be clamped or grasped by manipulator claws. And because paper has a certain degree of air permeability, it cannot be grasped by vacuum suction cups. Because if the vacuum suction cup is used for adsorption, it will often absorb three or four sheets of paper at a time.

In the process of making printed matter, the paper needs to be sorted and conveyed one by one. The invention discloses a new paper conveying method, which has the characteristics of simple structure and convenient maintenance.

Compared with the traditional technology, the flexible material conveying and correcting device based on the air suspension principle of the present invention has the following positive effects and beneficial effects:

A stack of paper is placed inside the loading plate, the stack of paper is located on the upper portion of the loading plate, and the pickup roller is located on the upper portion of the loading plate. When the paper pickup roller rotates, it will exert a certain frictional force on the paper located at the bottom of the paper stack, and the distance between the paper pickup roller and the loading plate is the thickness of the paper. Therefore, when the pickup roller drives the paper out of the paper stack, the number of paper coming out is one.

The present invention is a flexible material conveying and correcting device based on the principle of air suspension. The workbench is located in front of the output port of the paging machine, and the height of the workbench is lower than the height of the loading plate. The paper pick-up roller rotates to drive the paper at the lower part of the paper pile. When the paper is sorted out from the paper pile, the paper pick-up roller gives the paper a certain initial speed, so that the paper moves from the paper pile. When coming out of the discharge port, the paper has a certain kinetic energy.

When the paper leaves the outlet and arrives at the workbench, the kinetic energy of the paper will decrease, and at the same time, the attitude of the paper will change randomly and uncertainly. At this time, since the No. 1 air pipe is blowing air, the paper is pushed by the air flow and suspended by the air flow at the same time. The angle between the side limiting plate and the end limiting plate is a limiting angle; the No. 1 air pipe is located on the side of the workbench, and the central axis of the No. 1 air pipe extends to the Limiting angle; the direction of the airflow is directed from the No. 1 air pipe to the limiting angle. The No. 1 air pipe points to the limit angle, so the paper moves toward the limit angle under the transport of the airflow. Since the side of the workbench is provided with the side limiting plate, the side plate of the paper will contact the side limiting plate. The paper continues to move toward the direction of the end limiting plate under the push of the airflow until the end edge of the paper touches the end limiting plate.

At this moment, the airflow pressure inside the No. 1 air pipe is 0.2 MPa to 0.4 MPa, and the inner diameter of the No. 1 air pipe is 2 mm to 5 mm, and the air flow is blown out from the No. 1 air pipe. The side limiting plate is matched with the side edge, and the end limiting plate is matched with the end edge. When the No. 1 air pipe is closed instantly, the airflow suddenly disappears, which will cause the paper to fall freely from the state of being suspended by the airflow, causing the position of the paper to change. The side limit plate and the side edge No mating will be maintained, the end stop plate and the end edge will not remain mated. Therefore, it takes a certain amount of time to close the No. 1 air pipe, and the process of gradually reducing the airflow will keep the paper still: the side limit plate matches the side, and the end The limiting plate is matched with the end edge, and at the same time, the paper is gradually lowered onto the workbench.

A No. 2 air pipe is also provided on one side of the workbench, the No. 2 air pipe faces the side limiting plate, and the air flow is directed from the No. 2 air pipe to the side limiting plate. The airflow pressure inside the No. 2 trachea is 0.1 MPa to 0.2 MPa, and the inner diameter of the No. 2 trachea is 2 mm to 5 mm. The No. 2 air pipe plays an auxiliary role in pushing the paper, so that the paper ensures contact with the side limiting plate.

An introduction plate is also provided between the side limiting plate and the pager, and the introduction plate and the side limiting plate are smoothly and excessively connected. When the paper flies out from the outlet, the guide plate acts as a primary guide for the paper, so that the paper flies toward the working table.

A hollow groove is arranged on the side plate limiting plate, and a hollow hole is arranged on the end limiting plate. The hollow groove and the hollow hole improve the circulation of the airflow, so that the airflow can be kept as close as possible Laminar state. Therefore, the conveying process of the airflow to the paper is more stable.

The invention provides a flexible material conveying and correcting device based on the principle of air suspension, which is used for conveying flexible materials such as paper, and the page sorter conveys a piece of paper out of the pile of paper. The No. 1 air pipe imparts power to the paper to move the paper to the position where the side limit plate and the end limit plate are located. In the entire conveying process, except for the effect of airflow, there is no need for an additional mechanical structure conveying mechanism to push or stretch the paper, and the mechanical structure is simplified to the extreme. At the same time, during the conveying process, the paper is always in the forward motion process, the conveying efficiency is high, and the correction speed is fast.

The flexible material conveying and correcting device based on the principle of air suspension of the present invention will become clearer through the following description combined with the accompanying drawings, which are used to explain the embodiments of the present invention.
