Embodiment Construction

[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] like figure 1 As shown, in the embodiment of the method and device for detecting printed materials in the present invention, the method includes the following steps:

[0026] Step S11 detects the individual printed matter printed on the continuous material one by one: in this embodiment, this step is to pass the printed and rolled material through the feeding unit, unfold it, and pass through the detection unit in sequence to detect The unit checks and judges the individual prints printed on the above materials. Since the printed material is continuous in this embodiment, there are multiple independent individual prints printed on the material that are actually the pattern for each product the material is used for, in other words, These single prints on a material are virtually all of that material for each product. Each roll of material mentio...

Abstract

The invention relates to a method for detecting and rewinding a printed material, which comprises the following steps of: detecting single printed matters arranged on the material repeatedly one by one on a printed surface of the continuous printed material; processing the single printed matters which are detected to fail to come up to the standard; and rewinding the continuous material with the printed surface facing inward or outward. The invention also relates to a device for implementing the method. The implementation of the method and the device for detecting the printed material has thefollowing advantages that: because a computer imaging mode is adopted to detect the printing quality just after printing, and a processing unit is used for eliminating the parts with poor quality, furthermore, the printed surface of the material can face upward under various conditions through the direction changes of a same or different rewinding shafts, the method and the device for detecting the printed material can meet the requirements of different customers, and can discover and process the problems of the printing quality in time.

Description

technical field [0001] The present invention relates to printing equipment, more specifically, to a method and device for detecting printed materials. Background technique [0002] Generally speaking, for the printing of continuous materials (for example, flexible and roll-shaped materials), all of them are rewound after printing, and then unrolled for use. Therefore, the usual printing equipment for this material all includes a feeding unit and a rewinding unit. However, such equipment usually does not have the equipment to detect the material after printing, nor can it rewind the printed side inwards or outwards according to the needs of customers. It is only a simple rewinding after slitting. Therefore, it is not easy to find and remove the parts with poor printing quality in time when it is used, and it cannot satisfy the needs of customers to a certain extent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provi...
