Problems solved by technology

[0006] Although the above two patents can realize the non-manual cutting of PVC carpet, they do not solve the problem of how to identify the edge of the carpet accurately and in real time, that is, to identify the edge of the carpet when feeding, and determine the movement route of the cutter. Therefore, in the cutting process, the cutting error of the edge of the carpet is prone to be too large, and the cutting accuracy cannot be guaranteed, and the sitting efficiency is also very low.

Embodiment 1

[0048] figure 1 , Figure 10Among them, in this embodiment, it includes a cutting platform 6, and the cutting platform 6 cooperates with the discharge port of the pressure roller feeder 9, and the pressure roller feeder 9 includes a motor, a driving wheel and a driven wheel. There is a certain gap between the driving wheel and the driven wheel. During the hot-melt process of PVC carpet production, the PVC substrate is continuously moved out of the hot-melt mechanism with a fixed width. At this time, the cut carpet body can be rectangular sheets of various sizes, which have been placed on the PVC substrate to form the PVC carpet 11 . When feeding, the PVC carpet 11 is put into the gap, and the driving wheel presses the driven wheel and rotates to drive the PVC carpet 11 to advance, so that the PVC carpet 11 moves onto the cutting platform 6 . When the PVC carpet 11 covered the cutting area of ​​the cutting platform 6, the driving wheel stopped rotating.

Embodiment 2

[0068] Such as Figure 11 , Figure 11a As shown, in this embodiment, if the width of the cutting platform 6 is too large to cover the entire width direction with one line scan camera 1, multiple line scan cameras 1 can be used to coordinate work, and each line scan camera 1 Covering a part of the cutting platform 6 in the width direction, the combined images of multiple line scan cameras 1 can cover the entire width direction.

[0069] In this embodiment, two line array cameras 1 are used, and each line array camera 1 processes a part in the width direction of the cutting platform 6 to take pictures. The fields of view of the two line scan cameras 1 may partially overlap.

Abstract

The invention relates to a carpet automatic cutting device and a carpet automatic cutting method using real-time machine vision technology. The machine vision technology, and modern motor and control technology are adopted, and therefore in the process of carpet production, manual demands are reduced and labor intensity of workers is lowered. The carpet automatic cutting device comprises a cutting platform. The cutting platform is connected with a carpet feeding device, at least one imaging device for obtaining polyvinyl chloride (PVC) carpet images which enter a cutting region in real time is arranged above the connecting position between the cutting platform and the carpet feeding device, the imaging device enables the obtained images to be sent to a processor module, the processor module identifies edges of a carpet body in the images and then determines a cutting boundary, and a motion control module is used for controlling a cutting system installed on the cutting platform, and according to the determined cutting boundary, completing cutting of a PVC carpet.

Description

technical field [0001] The invention relates to a PVC carpet cutting device, in particular to an automatic carpet cutting device and method using real-time machine vision technology. Background technique [0002] Carpet is a very common item that has been widely used in many places such as homes, service places, factories, and offices. Among them, PVC carpet is the most widely used kind of carpet. The so-called PVC carpet is to paste the carpet body on the PVC substrate sheet by hot melting. The advantages of this PVC carpet are stable structure and convenient use. [0003] The traditional PVC carpet production and processing method is divided into three steps. The first step is to cut the carpet body into a preset size; the second step is to place the carpet body on a large piece of hot-melt PVC substrate sheet; the third step is to cut the large piece of PVC carpet according to the size of the carpet body PVC carpet cut into small pieces. The third step is currently do...
