The rest of the wood still needs a lot of manual sorting and post-processing of the large surface or side. According to the different specifications required, the number of equipment is multiplied. This undoubtedly increases the production cost of the enterprise and greatly hinders production efficiency. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 2 As shown, a sorting system for finger-joined materials based on contour detection is used for contour detection and sorting before wood processing, including a contour detection machine 1, a feeding conveyor line 2 and a sorting line 3. The front end of the conveying contour detection machine 1 is connected to the feeding conveyor line 2, and the rear end of the contour detection machine 1 is connected to the sorting line 3. A plurality of sorting kicks 4 are arranged on the conveying sorting line 3, and a contour detection device 5 is arranged on the contour detection machine 1.

[0023] Optionally or preferably, the contour detection machine further comprises a body 6 , the contour detection device 5 is arranged on the body 6 , and a feeding assembly 7 is arranged on the body 6 .

[0024] As an optional or preferred solution, a lateral chain conveyor 10 is further provided on the front platform of the fuselage 6, an anti-overlapping plate assembly is provided on the side of the front end of the fuselage 6, and a side pressure roller 9 is provided on the rear side of the lateral chain conveyor 10, and the side pressure roller 9 is installed on the fuselage 6.

[0025] An optional or preferred solution is that the anti-overlapping plate assembly includes a side plate 8.1 and a lower pressure plate 8.2, wherein the side plate 8.1 is arranged along the length direction of the fuselage 6, and the lower pressure plate 8.2 is vertically arranged along the length direction of the fuselage 6 through a column, and the lower pressure plate 8.2 can be adjusted up and down on the column.

[0026] Optionally or preferably, the contour detection device 5 includes a bracket 5.1 and a plurality of 3D laser contour sensors 5.2, the bracket 5.1 is in the shape of two groups of angle steels, a 3D laser contour sensor 5.2 is installed at both ends of each group of the brackets 5.1, and the brackets 5.1 are provided with protective covers.

[0027] As an optional or preferred solution, the sorting kicker 4 is a cylinder kicker arranged on one side of the sorting line 3; the sorting line 3 and the feeding assembly 7 are both driven by a servo motor.

[0029] The working principle of the finger-joined material sorting system based on contour detection provided by the utility model is as follows:

[0030] The front end wood passes through the cutting saw and then the feeding conveyor line 2 and the anti-overlapping plate assembly. Since the distance from the upper pressure plate 8.2 to the work surface is adjusted in advance, it is ensured that only one piece of wood can enter, effectively preventing the wood from stacking here. Then it is transported in batches and returned to the side through the lateral chain conveyor 10, the side pressure roller 9 and the feeding assembly 7. The wood passes through the contour detection device 5 and the 3D laser contour sensor 5.2 to obtain the contour information of the wood and upload it to the control system. The control system starts the sorting kick when the wood passes the corresponding sorting kick 4 according to the running speed of the sorting line 3 and the distance relationship between the wood and the corresponding sorting kick 4 to kick it out of the sorting line 3.

[0031] The utility model is described in detail above with reference to the accompanying drawings and embodiments, but the utility model is not limited to the above embodiments, and various changes can be made within the scope of ordinary technicians in the field without departing from the purpose of the utility model.
