Description

Technical Field

[0001] The invention relates to the technical field of furniture machinery, and in particular to a panel edge sealing feeding spacing control system. Background Art

[0002] As custom furniture becomes the main product in the furniture market, the shapes and lengths of the boards for custom furniture are different. In the edge banding process, some boards need to be banded on the short side first and then on the long side. The distance between the boards needs to be controlled when connecting these boards. Longer boards will collide when turning or rotating if the distance is not properly controlled.

[0003] At present, in order to reduce the possibility of collision of panels in the edge banding machine connection, the traditional technical approach is: when edge banding the panels, the operator needs to manually judge the distance between the panels according to the length of the wooden board and place the panels for processing so that the panels will not collide, or directly fix the distance between the panels according to the maximum board length. The former may cause mistakes in manual placement of the panels, and the latter will reduce production efficiency.

[0063] Please refer to Figure 1 The embodiment of the present invention provides a panel edge banding feed spacing control system, comprising a feed conveying mechanism 1, a distance measuring mechanism 2 and a central control unit 3; wherein,

[0064] The feeding and conveying mechanism 1 and the distance measuring mechanism 2 are respectively connected to the central control unit 3;

[0065] Specifically, the feeding and conveying mechanism 1 is responsible for feeding the panels to be edge-sealed into the subsequent processing flow in sequence and stably. Its design ensures the stability and accuracy of the panels during the conveying process, laying a solid foundation for the subsequent edge-sealing operation.

[0066] The distance measuring mechanism 2 is responsible for accurately measuring the length of each board to be edge-sealed. Through advanced sensing technology and algorithms, the mechanism can quickly and accurately obtain the length information of the board and transmit this key data to the central control unit 3 in real time.

[0067] The central control processing unit 3 is the "brain" of the entire system, and its importance is self-evident. It can not only receive the board length data from the distance measuring mechanism 2, but also accurately control the feeding and conveying mechanism 1 based on these data and the preset algorithm logic. By dynamically adjusting the conveying speed and position of subsequent boards, the central control processing unit 3 can ensure that boards of different lengths can maintain a safe distance on the turning line when the edge banding machine is in continuous operation, thereby effectively avoiding the occurrence of collision accidents.

[0068] In summary, the embodiment of the present invention not only realizes the precise control of the feed spacing in the plate edge banding operation, but also significantly improves the production efficiency and reduces the production cost by cleverly integrating the feed conveying mechanism 1, the distance measuring mechanism 2 and the central control processing unit 3. This innovative design scheme undoubtedly provides new ideas and possibilities for the technological progress and industrial upgrading of the plate edge banding industry, and has extremely high promotion value and practical value.

[0069] Please refer again Figure 1 In one implementation of this embodiment, the system further includes an industrial switch 4;

[0070] Specifically, the feed conveying mechanism 1 and the distance measuring mechanism 2 both use the industrial switch 4 as a bridge to achieve efficient and stable connection with the central control unit 3.

[0071] In one implementation of this embodiment, the central control unit 3 includes a keyboard, a display and an industrial computer;

[0072] The feeding conveying mechanism 1 and the distance measuring mechanism 2 are connected to the industrial computer directly or through a specific communication method to achieve data interaction and the issuance of control instructions;

[0073] Furthermore, the keyboard is connected to the industrial computer via a special keyboard interface, so that the operator can easily input instructions and data;

[0074] Similarly, the display is also connected to the industrial computer through a specific display interface, so that the system status, monitoring information and operation feedback can be clearly displayed.

[0075] Please refer to Figure 2 In one implementation of this embodiment, the feed conveying mechanism 1 is a highly integrated subsystem with a complex internal structure and complete functions, specifically including a programmable controller 11, a conveying unit, a plate separation unit, a conveying control unit 12 and a plate separation control unit 13;

[0076] The programmable controller 11, as the "brain" of the entire feeding and conveying mechanism 1, is responsible for receiving instructions from the central control unit 3 and accurately regulating the operation of the system according to these instructions. It ensures the real-time transmission and response of information between systems through a stable communication connection established with the central control unit 3.

[0077] Furthermore, the conveying control unit 12 and the panel separation control unit 13, as direct subordinates of the programmable controller 11, respectively undertake the precise control tasks of the conveying unit and the panel separation unit. Both control units are connected to the programmable controller 11 through a specific communication interface, thereby achieving real-time monitoring and flexible regulation of the working status of each responsible unit.

[0078] Specifically, the conveying control unit 12 accurately controls the running speed, position and other parameters of the conveying unit according to the instructions of the programmable controller 11 to ensure that the material can be accurately conveyed to the designated location according to the predetermined path and speed. The plate separation control unit 13 is responsible for accurately controlling the plate separation unit according to the instructions to achieve effective separation and processing of the material.

[0079] In summary, through this series of precise components and efficient communication mechanism, the feed conveying mechanism 1 is able to achieve precise control of material conveying and panel separation, thereby effectively improving the operating efficiency and stability of the entire system.

[0080] Please refer again Figure 2 In one implementation of this embodiment, the conveying control unit 12 is extremely precise and powerful, and specifically includes a first photoelectric switch 121, a first I / O module 122, a frequency converter 123, and a feed conveying motor 124. These components work together to achieve precise control of the material conveying process;

[0081] First, the inverter 123, as a key device for adjusting the motor speed, establishes a stable and efficient communication connection with the programmable controller 11 through the advanced MODBUS-RS485 communication protocol. This connection method not only ensures the real-time transmission of instructions, but also greatly improves the response speed and stability of the system.

[0082] Secondly, the first photoelectric switch 121 is an important sensor for detecting whether the plate has reached the specified position, and it realizes I / O connection with the programmable controller 11 through the first I / O module 122. When the first photoelectric switch 121 detects the plate, it will immediately send a signal to the programmable controller 11 to trigger the subsequent control process.

[0083] After receiving the detection signal from the first photoelectric switch 121, the programmable controller 11 will accurately control the speed, start and stop of the feed conveying motor 124 through the frequency converter 123 according to the preset program logic. In this process, the frequency converter 123 flexibly adjusts the speed of the feed conveying motor 124 according to the instructions of the programmable controller 11, thereby realizing accurate control of the material conveying speed. At the same time, when it is necessary to stop conveying, the frequency converter 123 will also quickly cut off the power supply of the motor according to the instructions to ensure the smoothness and safety of the conveying process.

[0084] In summary, through this series of precise components and efficient communication mechanism, the conveying control unit 12 is able to achieve precise control of the material conveying process, thereby effectively improving the operating efficiency and stability of the entire system.

[0085] Please refer again Figure 2 In one implementation of the present embodiment, the construction of the panel separation control unit 13 also reflects a high degree of integration and intelligence. It includes a position module 131, a second I / O module 132, a solenoid valve 133 and a panel separation cylinder 134. These components cooperate with each other to jointly achieve precise control of the panel separation process.

[0086] First, as a key component for determining the position of the panel, the position module 131 establishes a stable I / O connection with the programmable controller 11 through the second I / O module 132. This connection ensures that the position module 131 can feed back the position information of the panel to the programmable controller 11 in real time, providing reliable data support for subsequent precise control.

[0087] Secondly, the solenoid valve 133, as an important component for controlling the on-off of the gas circuit, is also connected to the programmable controller 11 through the second I / O module 132. When the first photoelectric switch 121 detects that the plate reaches the specified position, the programmable controller 11 sends a control signal to the solenoid valve 133 through the second I / O module 132 according to the preset program logic.

[0088] After receiving the control signal, the solenoid valve 133 will respond quickly, open or close the air circuit, thereby controlling the telescopic action of the plate separation cylinder 134. As an actuator, the precise telescopic action of the plate separation cylinder 134 can drive the plate separation unit to complete the separation operation of the plate.

[0089] In summary, through this series of precise components and efficient communication mechanism, the panel separation control unit 13 can achieve precise control of the panel separation process. When the first photoelectric switch 121 detects the panel, the solenoid valve 133 will respond quickly, control the panel separation cylinder 134 to drive the panel separation unit to complete the separation action, thereby ensuring the operating efficiency and stability of the entire system.

[0090] Please refer to Figure 3 In one implementation of this embodiment, the distance measuring mechanism 2 exhibits excellent performance with its highly integrated and intelligent design. The mechanism mainly includes a distance measuring controller 21, a second photoelectric sensor 22, a third I / O module 23 and a distance measuring light curtain 24, which work together to achieve accurate measurement of the length of the plate.

[0091] First, the distance measurement controller 21, as the "brain" of the distance measurement mechanism 2, is responsible for receiving instructions from the central control unit 3 and accurately regulating the distance measurement process according to these instructions. It establishes a stable communication connection with the central control unit 3 to ensure the real-time transmission and response of instructions.

[0092] Secondly, the distance measuring light curtain 24, as a key device for measuring the length of the plate, establishes an efficient and stable communication connection with the distance measuring controller 21 through the advanced MODBUS-RS485 communication protocol. This connection method not only ensures the real-time transmission of the measurement data, but also greatly improves the accuracy and stability of the measurement.

[0093] Furthermore, the second photoelectric sensor 22 is used as a sensor to detect whether the plate has reached the measuring position, and it realizes I / O connection with the distance measuring controller 21 through the third I / O module 23. When the second photoelectric sensor 22 detects that the plate has reached the specified measuring position, it will immediately send a signal to the distance measuring controller 21 to trigger the distance measuring light curtain 24 to measure the length.

[0094] After receiving the detection signal from the second photoelectric sensor 22, the distance measuring controller 21 will start the distance measuring light curtain 24 to measure the length of the plate according to the preset program logic. The distance measuring light curtain 24 can accurately measure the length of the plate through its internal precision grating structure and transmit the measurement data back to the distance measuring controller 21 in real time.

[0095] After receiving the measurement data, the distance measurement controller 21 will process and store the measurement data, and transmit the data to the central control unit 3 as needed for subsequent analysis and decision-making.

[0096] In summary, through this series of precise components and efficient communication mechanism, the distance measuring mechanism 2 is able to achieve accurate measurement of the length of the plate, thereby effectively improving the operating efficiency and measurement accuracy of the entire system.

[0097] In a specific and in-depth implementation of this embodiment, the structure of the ranging light curtain 24 is further refined and explained. As the core device for measuring the length of the plate, the ranging light curtain 24 is mainly composed of two key components, a receiver and a transmitter, which work together to achieve accurate measurement of the length of the plate.

[0098] Specifically, the transmitter is responsible for transmitting signals to the receiver, and these signals will reach the receiver unimpeded and be received by it under normal circumstances. However, when a plate passes through the ranging light curtain 24, the plate will block part or all of the signal, causing the signal received by the receiver to change.

[0099] In order to accurately capture this change, the second photoelectric sensor 22 is responsible for detecting whether the plate reaches the measuring area of ​​the ranging light curtain 24. Once the second photoelectric sensor 22 detects that the plate has passed, it immediately sends a signal to the ranging controller 21 to trigger the ranging light curtain 24 to measure.

[0100] After receiving the trigger signal from the second photoelectric sensor 22, the distance measuring controller 21 starts to receive the signal transmitted by the receiver of the distance measuring light curtain 24. Due to the shielding of the plate, the number of signals received by the receiver will change, and this change will be captured by the receiver and converted into a digital signal, which is then transmitted to the distance measuring controller 21.

[0101] After receiving these blocking signals, the distance controller 21 will use a preset algorithm to calculate. According to the blocking conditions of the signals, the distance controller 21 can accurately calculate the length of the board in the measurement area of ​​the distance light curtain 24, thereby achieving accurate measurement of the length of the board.

[0102] In summary, through the coordinated work of the receiver and transmitter of the ranging light curtain 24 and the precise triggering of the second photoelectric sensor 22, the ranging mechanism 2 is able to achieve rapid and accurate measurement of the length of the plate, providing strong support for the efficient operation of the entire system.

[0103] In a specific and in-depth implementation detail of this embodiment, when calculating the length of the panel, the ranging controller 21 uses a formula based on the working principle of the ranging light curtain 24, combining the length of the adjacent signal interval with the number of blocked signals to obtain the accurate length of the panel.

[0104] Specifically, the distance controller 21 first obtains the number of blocked signals transmitted by the receiver of the distance light curtain 24. These signal numbers represent how many light curtain signals are blocked by the plate during the measurement process. At the same time, the distance controller 21 also obtains a key parameter, namely the length of the interval between adjacent signals. This parameter is determined during the design and manufacture of the distance light curtain 24, and it represents the physical distance between two adjacent signals in the light curtain.

[0105] After obtaining these two key parameters, the distance measurement controller 21 can use the following formula to calculate the length of the plate:

[0106] Board length = length of adjacent signal interval × number of blocked signals

[0107] This formula is simple and clear, but very effective. By multiplying the length of the adjacent signal interval and the number of blocked signals, the distance controller 21 can quickly and accurately calculate the length of the plate within the measurement area of ​​the distance light curtain 24.

[0108] It is worth noting that the accuracy of this formula depends largely on the accuracy and stability of the ranging light curtain 24. Therefore, in practical applications, it is necessary to ensure that the receiver of the ranging light curtain 24 can accurately capture the changes in the signal and that the length of the interval between adjacent signals remains constant. Only in this way can the calculated length of the panel be guaranteed to have sufficient accuracy and reliability.

[0109] In summary, by using this concise and precise formula, the distance measurement controller 21 can achieve fast and accurate measurement of the length of the plate, providing strong support for the efficient operation of the entire system.

[0110] Although the terms such as feed conveying and distance measurement are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
