Embodiment 1
[0045] Such as figure 1 and Figure 4 As shown, the present invention provides a device for rejecting defective gypsum boards and its implementation method. In this embodiment, the rejecting method for defective gypsum boards does not directly act on the surface of gypsum boards, but by placing the defective gypsum boards at The conveying chain rotates until the gypsum board is transferred from the conveying chain to the waste conveyor belt by its own gravity, so as to realize the removal and removal of defective gypsum boards. The time requirement is not strict, and a certain time delay for waste removal regulation is allowed, and the adaptability is strong.
[0046]In addition, most of the existing waste removal and rejecting mechanisms are directly provided with a side push mechanism on the side of the conveyor belt, and the side push mechanism acts on the side of the gypsum board to realize waste removal, but because the thickness of the gypsum board is mostly 9.5cm-15cm,...
Embodiment 2
[0072] Such as Figure 5 As shown, based on the above-mentioned online rejecting device for defective gypsum boards, the present invention also provides a method for implementing the rejecting device, which includes the following steps:
[0073] Step 100, work in the quality inspection marking area, transport the dried gypsum boards, inspect the quality of the gypsum boards, and mark defective products that are not qualified.
[0074] Step 200, identify the work of the quality inspection mark area, identify the gypsum board mark to distinguish good products from defective products, send the information of defective products to the control system, and the control system generates a rejection instruction.
[0075] When the identification quality inspection mark area detects that there is a mark on the gypsum board, it means that the gypsum board is a defective product, and the control system generates a rejection command for controlling the work of the flipping rejection area. W...

Abstract
The embodiment of the invention discloses a defective gypsum board product removing device and an implementation method. The defective gypsum board product removing device comprises a printing and marking mechanism, a visual monitoring mechanism and removing mechanisms which are sequentially arranged in the conveying direction of gypsum boards, wherein the printing and marking mechanism is arranged on the front drying treatment section of the gypsum boards and marks the positions close to the edges of defective gypsum board products; the visual monitoring mechanism is arranged on the rear drying treatment section of the gypsum boards and transmits gypsum board images shot in real time into a processor; and te processor identifies and authenticates the shot gypsum board images, judges the quality of the gypsum boards and the distribution positions of the marks of the defective gypsum board products in one set of gypsum boards according to the marks of the defective gypsum board products, and automatically removes the defective gypsum board products at different distribution positions in the two sets of removing mechanisms correspondingly. According to the scheme, a conveying chain at the positions where the defective gypsum board products are positioned is rotated, the removing coverage range is wide, the requirement for the time of waste removing work is not strict, and adaptability is high.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of gypsum board production, and in particular to a device for rejecting defective gypsum boards and an implementation method thereof. Background technique [0002] Paper-faced gypsum board is a board made of building gypsum as the main raw material, mixed with appropriate amount of additives and fibers as the board core, and made of special cardboard as the surface protection. Paper-faced gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance, and simple construction method. [0003] The unqualified products in the existing gypsum board production are almost all unqualified in size due to the thicker processing of the board core. In production, the unqualified gypsum board is mostly observed by the naked eye of the employees, and then marked and transported to the back end At the rejecting device, the marked plasterboa...
