After the insertion rods 354 are inserted into the veneer conveying frame 7, the veneer conveying frame 7 is lifted up through the up and down moving mechanism 353. After the veneer conveying frame 7 is lifted to a certain height, the raised veneer conveying frame 7 is moved to the top of the corresponding first placing platform 4111 through the continued action of the left and right moving mechanism, and then, through the action of the up and down moving mechanism 353, the veneer conveying frame 7 is placed on the first placing platform 4111, so that the transporting mechanism 35 completes the transport of a veneer conveying frame 7, and the controller realizes the operation control of the fourth cylinder, the horizontal screw transmission mechanism and the vertical screw transmission mechanism.

[0044] The process of inserting and drying veneers of the present invention is as follows: the vacant veneer conveying frame 7 placed on the eighth conveying mechanism 83 of the frame is sequentially conveyed to the second conveying mechanism 32 of the frame through the eighth conveying mechanism 83 and the first conveying mechanism 31 of the frame, and the veneer conveying frame 7 is intermittently moved on the second conveying mechanism 32 of the frame. During the intermittent process of the veneer conveying frame 7, the veneer inserting mechanism 2 cooperates with the intermittent movement of the veneer conveying frame 7 to insert veneers into the veneer conveying frame 7. When the veneer conveying frame 7 is filled with veneers, the veneer conveying frame 7 is just pushed out. The veneer conveying rack 7 moves to the third conveying mechanism 33 of the work frame. The movement of the third conveying mechanism 33 of the work frame realizes the movement of the veneer conveying rack 7. The positioning of the veneer conveying rack 7 is realized by the action of the telescopic limit plate 3322. After the veneer conveying rack 7 is positioned, the veneer conveying rack 7 can be transported to the corresponding first placing platform 4111 through the transport mechanism 35. The veneer conveying rack 7 on the first placing platform 4111 can be driven to the corresponding placing position through the fourth conveying mechanism 4113 of the work frame, thereby completing the veneer insertion and drying process on the veneer conveying rack 7.During the above-mentioned veneer drying process, when the second photoelectric detection switch 301 does not detect the presence of the veneer conveying rack 7 above it, the controller starts the eighth conveying mechanism 83 of the rack and the first conveying mechanism 31 of the rack to replenish the veneer conveying rack 7 above the second photoelectric detection switch 301, so as to ensure that the veneer conveying rack 7 on the second conveying mechanism 32 of the rack is replenished. When the third photoelectric detection switch 302 detects the presence of the veneer conveying rack 7 above it, the controller controls the veneer conveying rack 7 to cooperate with the veneer insertion mechanism 2 for intermittent operation. , every time the veneer inserting mechanism 2 outputs a piece of veneer, the veneer conveying frame 7 moves once. When the fourth photoelectric detection switch 303 detects that there is a veneer conveying frame 7 above it (at this time, the veneer conveying frame 7 is full of veneers), the third conveying mechanism of the frame starts to operate. At the same time, the controller starts the telescopic limit plate 3322 corresponding to the fifth photoelectric detection switch 304 according to whether the fifth photoelectric detection switch 304 sends a signal that the veneer conveying frame 7 is detected. When all the fifth photoelectric detection switches 304 in a vertical row have a signal, the controller starts the telescopic limit plate 3322 corresponding to the fifth photoelectric detection switch 304. When one of the fifth photoelectric detection switches 304 sends a signal that the veneer conveying rack 7 is not detected, the telescopic limit plates 3322 opposite to the fifth photoelectric detection switches 304 in a vertical row are extended. After the veneer conveying rack 7 is positioned by the telescopic limit plates 3322, the transport mechanism transports the veneer conveying rack 7 to the corresponding first placement platform 4111. The order in which the transport mechanism places the veneer conveying rack 7 is determined according to the detection signal of the fifth photoelectric detection switch 304. The controller places the veneer conveying rack 7 according to the detection signal of all the fifth detection switches 304. The signal of the veneer conveying rack 7 is detected, so that the conveying mechanism fills the veneer conveying racks 7 on each placement mechanism in a placement order from bottom to top and from front to back. The conveying movement trajectory of the conveying mechanism during the above-mentioned conveying process is designed according to the up and down heights and front and back positions of each first placement platform 4111, so that the conveying mechanism can convey the veneer conveying rack 7 to the corresponding first placement platform 4111. When all the fifth photoelectric detection switches 304 detect the presence of the veneer conveying rack 7, the controller stops continuing the veneer insertion and drying process.

[0045] The process of collecting the veneers in a stack is as follows: when the veneers have reached the drying stage, the transport mechanism on the right side of the third sliding guide rail 51 of the frame is operated to transport the veneer transport frames 7 located in each placement mechanism 411 to the upper front end position of the third sliding guide rail 51 of the frame one by one, and the veneer transport frames 7 located on the third sliding guide rail 51 of the frame are transported to the second placement platform 81 in turn through the fifth transport mechanism 52 of the frame, the sixth transport mechanism 53 of the frame, the seventh transport mechanism 54 of the frame and the steering mechanism. During the intermittent movement of the veneer transport frames 7 driven by the sixth transport mechanism 53 of the frame, the veneers can be collected and stacked manually or by a robot, thereby completing the process of collecting the veneers in a stack. In the above process, the controller controls the veneers according to all the sixth inspection mechanisms. The detection switch 305 sends a signal indicating the presence of the veneer conveying rack 7, and the veneer conveying rack 7 is transported in a sequence from bottom to top and from front to back. During the above-mentioned transporting process, the fourth conveying mechanism 4113 of the rack can always transport the veneer conveying rack 7 to the right end of the second rack sliding guide rail 4112, so as to realize the transport of the veneer conveying rack 7 thereon by the transporting mechanism 35. The movement trajectory and sequence of the transporting mechanism 35 are set according to the fixed placement position of the veneer conveying rack 7 located at the right end of the second rack sliding guide rail 4112 and the detection signals sent by each sixth detection switch 305. When all the sixth detection switches 305 do not send a signal indicating that the corresponding veneer conveying rack 7 is detected, the transporting mechanism stops the transporting work.
