A method and device for separating sheet material

Abstract

The present invention provides a method and apparatus for separating sheet material. Among them, the single piece of sheet material on the top layer is separated from the stacked sheet material by using the scanning suction cup, and the separated single piece of sheet material is peeled off from the scanning suction cup by using the adsorption sorting wheel. The mechanism drives the stacked sheet materials to rise continuously, maintaining the relative position of the top layer of sheet materials and the scanning suction cup. The device for separating sheet materials provided by the present invention realizes the continuous supply of sheet materials by using the sheet material stack lifting mechanism, and realizes the separation of sheet materials by vacuum adsorption of scanning suction cups, which can ensure the sheet materials absorbed each time. The quantity of the material is a sheet, the structure is simple, and the performance is stable.

Description

technical field [0001] The present invention relates to a device for separating sheet material and at the same time to a method for separating sheet material. Background technique [0002] In the prior art, the basic principle of the sorting device for sheet materials such as paper used by various high-speed sorting machines at home and abroad is as follows: use pneumatic blowing force to loosen the sheet materials, and then use Adsorption sorting wheels implement sorting. [0003] A good sorting state of pneumatic equipment needs to ensure a good dispersion of sheet materials, but there are certain uncertainties in loosening paper by blowing force, which is mainly manifested in the following points: 1. The dispersion of sheet materials is not good, which can easily cause a The condition that the stacked sheet materials pass through the sorting device at the same time cannot meet the requirements of single sheet sorting; 2. The deformation, thickness or specific gravity of ...

[0003] A good sorting state of pneumatic equipment needs to ensure a good dispersion of sheet materials, but there are certain uncertainties in loosening paper by blowing force, which is mainly manifested in the following points: 1. The dispersion of sheet materials is not good, which can easily cause a The condition that the stacked sheet materials pass through the sorting device at the same time cannot meet the requirements of single sheet sorting; 2. The deformation, thickness or specific gravity of the sheet material changes in physical parameters, which affect the dispersion degree of the sheet material; 3. The sheet material The unsatisfactory state of material sorting affects the positioning of sheet materials, which is not conducive to product quality inspection and product position control; 4. Due to improper adjustment by operators, the mismatch between the blowing mechanism and sheet materials results in out-of-order sorting, This is not allowed by the sorting machine process and must be stopped for processing

[0004] The low-speed sorting device uses friction wheels to separate sheet materials. The disadvantage is that it is difficult to increase the sorting speed, and it is impossible to effectively control the situation that double or multiple sheets are sorted at one time, and the sorting speed is low.
