Description

Technical Field

[0001] The present invention relates to the technical field of log processing, and specifically provides a log flipping and conveying device and method thereof. Background Art

[0002] Before logs enter a multi-blade sawing machine, a lengthened conveyor is generally installed to convey the logs. Before sawing, the logs are divided into two methods. First, the logs are directly conveyed to the multi-blade sawing machine for sawing. Second, the logs need to be flipped to find the most suitable position for sawing. In the existing methods of flipping logs, most of them are to lift the logs and then flip them. After finding the appropriate position, the logs are lowered and then conveyed to the multi-blade sawing machine for sawing.

[0003] The existing log flipping technology is that after the logs pass through the storage rack to the flipping rack, the flipping rack needs to lift the whole rack by pneumatic or electric means. After lifting, the flipping rack is controlled to flip left and right to find the most suitable position for sawing. Then the flipping rack is lowered, the logs come into contact with the bottom conveying chain, and the conveying chain is started to convey the logs to the multi-blade sawing machine for sawing.

[0004] For logs without flipping, the sawing yield is low; while for the method of flipping logs with a flipping rack, the whole flipping table needs to be lifted, resulting in high manufacturing costs and a large input of power source for lifting. When the logs come into contact with the conveying chain during the descending process after finding the suitable position for flipping, the logs will have a certain degree of deviation. After starting the conveying, the deviation increases, and the sawing position of the logs deviates greatly from the ideal sawing position, resulting in a reduction in the final sawing yield.

[0005] Based on this, the present invention designs a log flipping and conveying device and method thereof to solve the above problems. Summary of the Invention

[0006] The purpose of the invention is to provide a log flipping and conveying device and method thereof to solve the above technical problems.

[0007] To achieve the above purpose, the invention provides the following technical solutions:

[0008] Solution 1:

[0009] A log turning and conveying device, comprising a log storage rack, a main body of the conveying device, a main body of the turning device, a multi-blade saw for logs, and a movable electric control box. The log storage rack is arranged on the side of the feeding end of the main body of the conveying device, and is used for storing logs and laterally rolling and conveying the logs one by one to the main body of the conveying device. The main body of the turning device is arranged on the other side of the feeding end of the main body of the conveying device, and is used for turning the logs conveyed to the main body of the conveying device by a specific angle. The discharging end of the main body of the conveying device is connected to the multi-blade saw for logs, and is used for feeding the logs turned to the required angle into the multi-blade saw for logs for saw blade processing. The movable electric control box is electrically connected to the log storage rack, the main body of the conveying device, the main body of the turning device, and the multi-blade saw for logs respectively, and is used for controlling the operation of each processing procedure.

[0010] Preferably, the log storage rack includes a support platform rack. At the front and rear ends of the left and right sides of the top of the support platform rack, feeding sprockets are respectively arranged. The feeding drive chain is sleeved on the feeding sprockets at the front and rear ends. A feeding drive motor for driving the feeding sprockets and then driving the feeding drive chain to operate is installed in the support platform rack. Triangular retaining seats are arranged on both sides of the feeding end of the support platform rack.

[0011] Preferably, the main body of the conveying device includes a main body support and a track framework fixedly installed on the main body support. Conveying sprockets are rotatably installed at both ends of the inner cavity of the track framework, and a conveying chain is sleeved. A supporting chain plate is arranged between the upper and lower conveying chains on the inner side of the track framework. A plurality of rolling supports are fixedly arranged on the conveying chain at intervals. A conveying drive motor and a speed change transmission box for driving the conveying sprockets are installed on the side of the end of the track framework. Side guard baffles are arranged at intervals on the side of the track framework close to the main body of the turning device.

[0012] Preferably, the rolling support includes a rib plate seat with a V-shaped supporting notch at the top. A plurality of movable rollers are arranged side by side on the inclined sides on both sides of the V-shaped supporting notch. The axis of the movable roller is parallel to the conveying direction of the log on the conveying chain.

[0013] Preferably, the main body of the flipping device includes a vertical rod bracket. On one side of the vertical rod bracket away from the main body of the conveying device, a lifting cylinder is fixedly installed. On one side of the vertical rod bracket close to the main body of the conveying device, a slide rail slider assembly is installed. At the top of the vertical rod bracket, a reversing fixed pulley group is provided. The telescopic end of the lifting cylinder faces upward and is connected to a lifting transmission chain. After the lifting transmission chain bypasses the reversing fixed pulley group, it is connected to a lifting mounting seat. The side of the lifting mounting seat is installed on the slider of the slide rail slider assembly. The lifting mounting seat is located directly above the main body of the conveying device, and the bottom of the lifting mounting seat has a V-shaped flipping notch. At the V-shaped flipping notch, a V-shaped toothed chain is installed through a flipping sprocket fixedly installed on the lifting mounting seat. A flipping drive motor is installed on the lifting mounting seat to drive the flipping sprocket and then drive the V-shaped toothed chain to operate.

[0014] Solution 2:

[0015] A method for flipping and conveying round logs uses the round log flipping and conveying device of Solution 1 for the following processing method:

[0016] Place the round logs on the support platform frame at certain intervals. The feeding drive motor drives the feeding sprocket and then drives the feeding transmission chain to operate to laterally move and convey the round logs onto the main body of the conveying device.

[0017] After the round logs are conveyed to the rolling supports on the main body of the conveying device, the telescopic end of the lifting cylinder extends upward. The lifting mounting seat falls by its own weight until the V-shaped toothed chain abuts against the round logs. Then, the flipping drive motor drives the flipping sprocket and then drives the V-shaped toothed chain to operate, thereby driving the round logs to flip to the required angle. Then, the telescopic end of the lifting cylinder retracts to drive the lifting mounting seat to lift and separate from the round logs.

[0018] After the flipping is completed, the conveying drive motor drives the conveying sprocket and then drives the conveying chain to operate, thereby driving the round logs to be conveyed forward to the round log multi-blade sawing machine.

[0019] Compared with the prior art, the beneficial effects of the invention are:

[0020] In the invention, rolling supports are installed on the conveying chain for transporting round logs. The round logs are placed thereon and can rotate back and forth. One or more groups of flipping devices are supported on the side of the chain plate conveyor. The main body of the flipping device moves up and down by means of a lifting cylinder. After the round logs are placed on the rolling supports with bearings, the flipping device descends to contact the round logs. The flipping device is equipped with a powered chain that can move back and forth to drive the round logs to flip. After the round logs are flipped to the appropriate position, the flipping device rises, and the conveyor smoothly transports the round logs to the next process. It has the advantages of low cost, accurate flipping, simple operation, no deviation after flipping, etc., greatly improving the wood yield and production efficiency. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without creative efforts belong to the scope of protection of the invention.

[0035] Embodiment 1:

[0036] Please refer to Figure 1 , the invention provides a technical solution: a log turning and conveying device, including a log storage rack 100, a conveying device main body 200, a turning device main body 300, a log multi-blade saw 400 and a movable electric control box 500. The log storage rack 100 is arranged on the side of the feeding end of the conveying device main body 200, used for storing logs and laterally rolling and conveying the logs to the conveying device main body 200 one by one. The turning device main body 300 is arranged on the other side of the feeding end of the conveying device main body 200, used for turning the logs conveyed to the conveying device main body 200 by a specific angle. The discharging end of the conveying device main body 200 is connected to the log multi-blade saw 400, used for feeding the logs turned to the required angle into the log multi-blade saw 400 for saw blade processing. The movable electric control box 500 is electrically connected to the log storage rack 100, the conveying device main body 200, the turning device main body 300 and the log multi-blade saw 400 respectively, used for controlling the operation of each processing procedure.

[0037] Please refer to Figure 2 , the log storage rack 100 includes a support platform rack 110, which is built by using channel steel, square tube steel or profiles and is used for placing logs; on the front, rear, left and right sides of the top of the support platform rack 110, feeding sprockets 120 are respectively arranged, and feeding drive chains 130 are sleeved on the front and rear feeding sprockets 120. A feeding drive motor 140 for driving the feeding sprockets 120 to drive the feeding drive chains 130 to operate is installed in the support platform rack 110. Triangular retaining seats 150 are arranged on both sides of the feeding end of the support platform rack 110, and the triangular retaining seats 150 can prevent the logs from rolling to the feeding end side.

[0038] Please refer to Figure 3 and 4, the conveying device main body 200 includes a main body support 210 and a track framework 220 fixedly installed on the main body support 210. The track framework 220 includes two vertical plates arranged parallel and spaced apart left and right, and the two vertical plates are fixedly connected by connecting members; at both ends of the inner cavity of the track framework 220, conveying sprockets 230 are rotatably installed and a conveying chain 240 is sleeved. A supporting chain plate 250 is arranged between the upper and lower conveying chains 240 on the inner side of the track framework 220. When the top of the conveying chain 240 bears the gravity of the log, the weight is transmitted through contact with the supporting chain plate 250 at the bottom; a number of spaced rolling supports 260 are fixedly arranged on the conveying chain 240. The rolling supports 260 cover the entire conveying chain 240 and move with the conveying chain 240. When the log is flipped and conveyed, it is placed on the rolling supports 260; a conveying drive motor 270 and a speed change transmission box 280 for driving the conveying sprocket 230 are installed on the side of the end of the track framework 220. Side guard plates 290 are arranged at intervals on the side of the track framework 220 close to the flipping device main body 300 to prevent the log from rolling towards the flipping device main body 300 side.

[0039] Please refer to Figure 5 , the rolling support 260 includes a ribbed seat 262 with a V-shaped supporting notch 261 at the top. A number of movable rollers 263 are arranged side by side on the two inclined sides of the V-shaped supporting notch 261. The axes of the movable rollers 263 are parallel to the conveying direction of the log on the conveying chain 240. The V-shaped supporting notch 261 structure can be used to place logs with different diameters. The design of the movable rollers 263 enables the log to roll laterally and achieve flipping under the action of the flipping device main body 300 after being placed on it.

[0040] After the log is placed on the rolling support 260, the rolling support 260 is provided with movable rollers 263, which can flip the log. The start and stop of the conveying drive motor 270 drive the conveying chain 240 to run via the conveying sprocket 230, realizing the conveying of the flipped log.

[0041] Please refer to Figure 6, the main body 300 of the flipping device includes a vertical rod support 310. On one side of the vertical rod support 310 away from the main body 200 of the conveying device, a lifting cylinder 320 is fixedly installed. On one side of the vertical rod support 310 close to the main body 200 of the conveying device, a slide rail and slider assembly 330 is installed. At the top of the vertical rod support 310, a reversing fixed pulley group 340 is provided. The reversing fixed pulley group 340 includes two fixed pulleys arranged side by side left and right (blocked by the outer cover in the figure), realizing 180° circumferential transmission. The telescopic end of the lifting cylinder 320 faces upward and is connected with a lifting transmission chain 350. After the lifting transmission chain 350 bypasses the reversing fixed pulley group 340, it is connected with a lifting mounting seat 360. The side of the lifting mounting seat 360 is mounted on the slider of the slide rail and slider assembly 330. The lifting mounting seat 360 is located directly above the main body 200 of the conveying device, and the bottom of the lifting mounting seat 360 has a V-shaped flipping notch 370. At the V-shaped flipping notch 370, a V-shaped toothed chain 380 is installed through a flipping sprocket fixedly mounted on the lifting mounting seat 360. A flipping drive motor 390 for driving the flipping sprocket to drive the V-shaped toothed chain 380 to operate is installed on the lifting mounting seat 360.

[0042] By the telescopic movement of the lifting cylinder 320, via the lifting transmission chain 350 and the reversing fixed pulley group 340, the slider in the slide rail and slider assembly 330 moves up and down relative to the slide rail, thereby realizing the lifting of the lifting mounting seat 360. Then, by the start and stop of the flipping drive motor 390, the movement and stop of the V-shaped toothed chain 380 are realized, and further the flipping of the round log is realized.

[0043] Please refer to Figures 3 - 6 , combining the main body 200 of the conveying device and the main body 300 of the flipping device, the main body 300 of the flipping device is assembled on the upper part of the main body 200 of the conveying device through a support connecting plate. One set or multiple sets of the main body 300 of the flipping device can be installed. The main body 300 of the flipping device realizes up and down lifting through the control of the lifting cylinder 320. When the round log is on the rolling support 260 of the conveying chain 240, the lifting mounting seat 360 drops. Through the back-and-forth operation of the V-shaped toothed chain 380, the round log is flipped accordingly. After flipping to the most suitable position, the lifting cylinder 320 raises the lifting mounting seat 360, and then the conveying drive motor 270 is started to smoothly transport the round log to the next process.

[0044] The multi-blade saw 400 for round logs and the movable electric control box 500 are both existing standard equipment and conventional electric control components, and their detailed structures will not be elaborated in this embodiment.

[0045] Embodiment 2:

[0047] Place the logs on the support platform frame 110 at certain intervals. The feeding drive motor 140 drives the feeding sprocket 120, which in turn drives the feeding transmission chain 130 to operate, laterally shifting and conveying the logs onto the main body 200 of the conveying device.

[0048] After the logs are conveyed onto the rolling supports 260 of the main body 200 of the conveying device, the telescopic end of the lifting cylinder 320 extends upward. The lifting mounting seat 360 drops by its own weight until it abuts against the V-shaped toothed chain 380 and the logs. Then, the flipping drive motor 390 drives the flipping sprocket, which in turn drives the V-shaped toothed chain 380 to operate, thereby driving the logs to flip to the required angle. Next, the telescopic end of the lifting cylinder 320 retracts, driving the lifting mounting seat 360 to lift and disengage from the logs.

[0049] After the flipping is completed, the conveying drive motor 270 drives the conveying sprocket 230, which in turn drives the conveying chain 240 to operate, thereby driving the logs to travel and be conveyed towards the multi-blade log saw 400.
