Description

Technical Field

[0001] This invention relates to the field of reconstituted wood technology, and in particular to a reconstituted wood modified tank feeding system and feeding control method. Background Technology

[0002] With the continuous development of science and technology, wood reconstituted technology has received high attention from the state. Using fast-growing forests as raw materials, and through various physical and chemical processes, the properties of the wood can be effectively altered. This process can effectively conserve wood resources, enabling the recycling of fast-growing forests and improving the efficiency of wood use. Reconstituted wood is produced by crushing wood into "wood bundles" and recombining them without disrupting the fiber arrangement and preserving the basic characteristics of the wood. This results in a new type of wood with high strength, large dimensions, and a natural wood grain structure, which can completely replace solid hardwood and has superior performance.

[0003] In the reconstituted wood production process, timber needs to be transported to a modification tank for modification treatment. Traditionally, timber is transported using trolleys, which are manually controlled to move in and out of the modification tank. This method requires a large amount of manpower, increases labor intensity, and the transportation efficiency of manually operated trolleys is low, making continuous operation difficult. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a feeding system and feeding control method for reconstituted wood modified cans to solve the above problems.

[0005] To achieve the above objectives, the present invention provides a feeding system for modified reconstituted wood cans, comprising: a modified can, a proximity switch, a detection plate, a track, a feeding trolley, and an encoder; a proximity switch is installed on the ground at the position where the can door of the modified can is fully open; a plurality of evenly distributed detection points are arranged inside the modified can along the length of the can, and detection plates are installed on the detection points; a track is installed inside the modified can, and a feeding trolley is slidably connected to the track; an encoder is installed on the side of the feeding trolley, and an intelligent control system is installed on the feeding trolley, the intelligent control system being used to control the movement of the feeding trolley.

[0006] Furthermore, the feeding vehicle includes a vehicle body, a power supply, a drive system, a grabbing hook system, and a radar scanning system. The power supply and drive system are installed on the vehicle body respectively; the grabbing hook system is installed on the vehicle body for lifting and lowering the material frame; and the radar scanning system is installed at the end of the vehicle body for detecting the safety of the surrounding environment.

[0007] Furthermore, the grab hook system includes a bracket, a drive unit, an upper limit position, and a lower limit position. One end of the bracket is rotatably connected to the vehicle body, and the other end of the bracket is hinged to the output end of the drive unit. The drive unit is mounted on the vehicle body, and the upper and lower limits are connected to the upper and lower sides of the bracket, respectively.

[0008] Furthermore, the feeding vehicle is equipped with an infrared ranging device.

[0009] The feeding control method for reconstituted wood modified tanks is as follows: S1. Confirm that the tank door is fully open and the tank is empty; S2. Transport the material frame to the feeding trolley; S3. Control the grab hook system to rise to the upper position and hold the material frame in place; S4. Use a radar scanning system to detect the surrounding environment. If the surrounding environment is safe, start the feeding trolley; S5. During the operation of the feeding trolley, the encoder calculates the position and speed of the feeding trolley in real time. Until the feeding trolley reaches the second-to-last detection point, the encoder and infrared ranging device respectively detect the distance between the feeding trolley and the last detection point. When the distance is less than or equal to 500mm, control the feeding trolley to decelerate until the feeding trolley stops at the last detection point; S6. Control the grab hook system to descend to the lower position, feed the material into the modified tank, and the feeding trolley returns to the receiving trolley position.

[0010] Furthermore, a dual-feeder system is used to transport the material frames in a cyclical manner.

[0011] Furthermore, during the operation of the feeding car, a maximum deviation is set in the intelligent control system. The intelligent control system compares the position and speed of the feeding car detected by the encoder with the position and speed of the feeding car under ideal conditions in real time. If the intelligent control system detects a deviation in the position or speed of the feeding car detected by the encoder, it will perform corrective processing; if the deviation is greater than the maximum deviation, it will stop and alarm.

[0012] Compared with existing technologies, the advantages of this invention are as follows: This invention uses an intelligent control system to control the feeding cart, and with the cooperation of an encoder and a detection plate, the position of the feeding cart is monitored in real time. This invention achieves unmanned, intelligent control of modified tank feeding, enabling continuous operation, saving production costs, and improving production efficiency.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0020] like Figures 1 to 5 As shown, the present invention proposes a reconstituted wood modified can feeding system, which consists of a modified can 1, a proximity switch, a detection plate, a track 2, a feeding trolley 4, and an encoder 5. A proximity switch is installed on the ground at the position where the can door 13 of the modified can 1 is fully open, used to determine whether the can door 13 of the modified can 1 is fully open. A track 2 is installed inside the modified can 1, and a feeding trolley 4 is slidably connected to the track 2, allowing the feeding trolley 4 to enter and exit the modified can 1 via the track 2.

[0021] An encoder 5 is installed on the side of the feeding trolley 4. The encoder 5 is integrated with the axle of the trolley body 11 and is installed outside the center point of the axle. Several evenly distributed detection points are arranged along the length of the modified tank 1, and detection plates are installed on each detection point. In this embodiment, ten detection points are set, and these ten detection points are labeled as stations 1 to 10 along the conveying direction of the wood to be processed. With the cooperation of the encoder 5 and the detection plates, the position of the feeding trolley 4 is monitored in real time.

[0022] The feeding cart 4 consists of a body 11, a power supply 12, a drive system 7, a hook system, and a radar scanning system 10. The power supply 12 and drive system 7 are mounted on the body 11. The power supply 12 provides power to the electrical equipment, and the drive system 7 drives the body 11. The hook system is mounted on the body 11 and is used to lift the material frame 3. The hook system consists of a bracket 8, a drive component 9, an upper limit switch, and a lower limit switch. One end of the bracket 8 is rotatably connected to the body 11, and the other end is hinged to the output end of the drive component 9, which is mounted on the body 11. The upper and lower limit switches are connected to the upper and lower sides of the bracket 8, respectively. The radar scanning system 10 is mounted at the end of the body 11 and is used to detect the safety of the surrounding environment. The feeding cart 4 is equipped with an intelligent control system 6, which controls the movement of the feeding cart 4 and transmits signals with the radar scanning system 10, encoder 5, etc. The feeding cart 4 is also equipped with an infrared ranging device to measure the distance between the feeding cart 4 and the detection point.

[0023] The feeding control method for modified reconstituted wood cans shall be carried out according to the following steps:

[0024] S1. Based on the detection signal of the proximity switch, confirm that the door 13 of the modified tank 1 is fully open and that the modified tank 1 is empty.

[0025] S2. The material frame 3 is transported to the feeding car 4 through the production line conveyor system.

[0026] S3. Control the hook system to rise to the rising position, hold the material frame 3 in place, and prepare to send the feeding car 4 into the modified tank 1.

[0027] S4. The radar scanning system 10 is used to detect the surrounding environment. If the surrounding environment is safe, an audible and visual alarm is issued and the feeding car 4 is started.

[0028] S5. During the operation of the feeding car 4, the encoder 5 calculates the position and speed of the feeding car 4 in real time until the feeding car 4 reaches the penultimate detection point, i.e., the ninth detection point. The encoder 5 and the infrared ranging device respectively detect the distance between the feeding car 4 and the last detection point, i.e., the distance between the feeding car 4 and the tenth detection point. When the distance is less than or equal to 500mm, the encoder controls the feeding car 4 to decelerate until the feeding car 4 stops at the last detection point, and the encoder 5 automatically zeroes.

[0029] S6. Control the hook system to descend to the lowering position, send the material into the modified tank 1, and the feeding car 4 returns to the receiving car position.

[0030] During the operation of the feeding car 4, a maximum deviation is set in the intelligent control system 6, which is a manually set value. The intelligent control system 6 compares the position and speed of the feeding car 4 detected by the encoder 5 with the ideal position and speed of the feeding car 4 in real time. If the intelligent control system 6 detects a deviation in the position or speed of the feeding car 4 detected by the encoder 5, it performs corrective processing. If the deviation is greater than the maximum deviation, a stop alarm is triggered.

[0031] To improve conveying efficiency, a dual-feeding cart 4, designated as cart A and cart B, circulates and transports the material frames 3. Initially, cart B waits at station 2 while cart A transports the material frame 3 to station 1. Cart A then returns to receive material, while cart B simultaneously moves from station 1 to station 10. This process repeats until the modified tank 1 is full of material frames 3. After carts A and B complete their feeding, both carts 4 automatically return to their initial positions for wireless charging. The modified tank 1 is then closed to proceed to the next process step. After modification is complete, the modified tank 1 is opened. Cart B transports the material frame 3 from station 10, while cart A transports the material frame 3 from station 9 to station 10 to await cart B's removal of the modified tank 1. This process continues until all transportation is complete.

[0032] This invention employs an intelligent control system 6 to control the feeding cart 4, and with the cooperation of the encoder 5 and the detection plate, the position of the feeding cart 4 is monitored in real time. This invention achieves unmanned, intelligent control of the feeding of the modified tank 1, enabling continuous operation, saving production costs, and improving production efficiency.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
