The line dividing frame 41 is provided with a line dividing driving device 44, the upper end of the line dividing frame 41 is provided with a line dividing conveying device 43, and the lower part is provided with an automatic material turning device. At least two side guide plates 45 are fixed at intervals on one side of the line dividing frame 41, the line dividing driving device drives the line dividing conveying device 43, and the upper end surface of the side guide plate 45 is extended outward from the end of the line dividing frame 41.

[0054] As attached Figure 1 As shown, the present invention can be provided with at least three unit transverse conveying devices at intervals on the feed rack 10 to achieve the purpose of carrying logs of different lengths.

[0055] As attached Figure 2As shown, the unit transverse conveying device of the present invention includes a conveying chain 53 and a chain support frame 54.

The conveying chain 53 bypasses the chain support frame 54 and meshes with the feed driving sprocket 57 and the feed driven sprocket 58 respectively, so as to achieve the effect of smoothly conveying logs through the conveying chain.

[0056] like Figure 1 As shown, in the present invention, a support plate 60 may be vertically fixed on one side of the feed rack, so as to provide a reference support surface for the feeding of logs through the support plate, so as to ensure the detection accuracy of the logs.

[0057] like Figure 1 As shown, the present invention can also provide a stopper block 61 at the feed end of the feed rack, the upper end surface of the stopper block is higher than the upper end surface of the conveyor chain and the front end thereof is provided with an inclined guide surface, so as to facilitate the introduction of logs onto the conveyor chain through the inclined guide surface, and at the same time, it can also prevent the logs from rolling down the feed rack when falling and causing accidents.

[0058] Embodiment: The present invention can select the diameter of φ170-φ600mm, and the mixed length of 8 feet, 6 feet, 4 feet, and 3 feet for online automatic transportation, detection, line separation, and storage. In this embodiment, 4 unit horizontal line conveying devices are arranged at intervals. This embodiment is used to explain the detection and line separation process of the present invention in detail:

[0059] During operation, the operator clicks the automatic start button on the touch screen, and the control device instructs the feed drive device in the log feed device 12 to drive the transverse conveying device to rotate. The operator uses a mobile device such as a forklift to move 8-foot and / or 6-foot and / or 4-foot logs to the feed rack. One end of the log is lowered using the support plate on one side of the feed rack as a reference. The log falls on the conveying chain of the feed rack. The log moves toward the log detection device driven by the transverse conveying device. When the log is transported to the guide plate 14 by the transverse conveying device 12, the first sensor uploads the log arrival information to the feed rack. To the control device, the control device instructs the linkage cylinder 18 to act, pulls the connecting rod 19, and the connecting rod 19 moves to the rear of the feeding rack 10, driving the linkage shaft 17 to rotate, so that the upper bevel of the log lifting plate 16 contacts the side wall of the log and applies a thrust, pushing the log along the bevel of the guide plate 14 to the longitudinal conveying device of the log detection device, and then, the control device 9 instructs the linkage cylinder 18 to return, and the log lifting plate 16 rotates in the opposite direction driven by the linkage shaft 17, and the upper bevel of the log lifting plate 16 is lower than the upper end surface of the transverse conveying device 12, making the automatic feeding of logs smoother;

[0060] When the log rolls down on the longitudinal conveying device, if the log diameter is very thick, when rolling down, under the action of inertia, in order to prevent the log from rolling out of the detection frame, the log is blocked and limited by the baffle plate. When the second sensor senses that the log has reached the V-shaped support block on the detection frame, the second sensor uploads the information to the control device 9, and the control device 9 instructs the log diameter detection device and the longitudinal drive device to operate. The log is positioned by the V-shaped positioning block on the annular belt body, and moves with the rotation of the annular belt body, and moves to the unit log dividing device. During the movement, the log length detection encoder uploads the log length information to the control device. When passing through the log diameter detection device, The XY photoelectric detection sensor scans the online logs to measure the real-time diameter of the logs and uploads it to the PLC controller. The program in the PLC controller calculates the average diameter, length, and volume, which are remotely transmitted to the computer or mobile phone, so that the operator does not need to pay attention all the time, and can view it remotely on the computer or mobile phone in advance, or print it out through a printer connected to the computer. In a line splitting device, such as the present embodiment, four different types of unit log line splitting devices can share a line splitting drive device, or they can be set up separately. The present invention preferably uses a shared line splitting drive device. The structure of the line splitting drive device is the same as that of the longitudinal drive device, which is not repeated here, so as to achieve the effect of saving energy.

[0061] When the detected log length is 4 feet, the control device starts the line dividing drive device in the unit log dividing device, and the line dividing drive device drives the line dividing conveyor device to operate and convey the logs to the 4-foot log dividing device. When the log in-place sensor on the 4-foot log dividing device senses the log in-place information, the control device instructs the line dividing conveyor device to stop, and then instructs the turning cylinder on the 4-foot log dividing device to operate. The turning cylinder 49 pushes the turning frame 47 to rotate around the rotating shaft 48, so that the turning plate 46 at the upper end of the turning frame 47 tilts the log to roll to the side of the line dividing frame 41, and turns the log onto the side guide plate 45. In the process of turning the log, the log is conveyed to the wood storage groove of the unit log receiving device through the inclined surface of the side guide plate 45, the tilting of the turning plate and the lifting of the weight-reducing frame. While realizing automatic line dividing, it also ensures the stability of log rolling out.

[0062] Similarly, when the detected log length is 6 feet, the control device and the command line conveying device are activated to transport the log to the 6-foot log line dividing device and store the log in lines. The action is the same as the above-mentioned 4-foot log line dividing action and will not be repeated here.

[0063] Similarly, when the detected log length is 8 feet, the control device and the command line conveying device are activated to transport the log to the 8-foot log line dividing device and store the log in lines. The action is the same as the above-mentioned 4-foot log line dividing action and will not be repeated here.

[0064] Due to the adoption of the above structure, the present invention has the advantages of novel structure, high degree of automation, stable transportation, high detection accuracy, time and labor saving, high work efficiency, and quick line division.
