Description

Technical Field

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

[0002] As custom furniture becomes a staple in the furniture market, the wood panels used for these pieces vary in shape and length. During edge banding, some boards require the short edges to be banded first, followed by the long edges. These boards require controlled distances between the panels during assembly. Improper distance control can cause collisions when long panels are turning or rotating.

[0003] At present, in order to reduce the possibility of collision between 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 based on 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 based on the maximum panel length. The former may cause mistakes in manual placement of 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-banded into the subsequent processing flow in a sequential and stable manner. Its design ensures the smooth and accurate conveying of the panels, laying a solid foundation for the subsequent edge-banding operation.

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

[0067] The central control processing unit 3, the "brain" of the entire system, is of undeniable importance. It not only receives panel length data from the distance measuring mechanism 2 but also precisely controls the feed conveyor mechanism 1 based on this data and pre-set algorithmic logic. By dynamically adjusting the conveying speed and position of subsequent panels, the central control processing unit 3 ensures that panels of different lengths maintain a safe spacing on the return line while the edge banding machine continues to operate, effectively preventing collisions.

[0068] In summary, the present embodiment, through the ingenious integration of the feed conveyor mechanism 1, the distance measuring mechanism 2, and the central control processing unit 3, not only achieves precise control of the feed spacing during panel edge banding operations, but also significantly improves production efficiency and reduces production costs. This innovative design solution undoubtedly provides new ideas and possibilities for technological advancement and industrial upgrading in the panel edge banding industry, and has extremely high promotional 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 feeding and conveying mechanism 1 and the distance measuring mechanism 2 both achieve efficient and stable connection with the central control unit 3 by means of the industrial switch 4 as a bridge.

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

[0072] The feeding and 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 dedicated keyboard interface, so that the operator can easily input instructions and data;

[0074] Likewise, the display is also connected to the industrial computer via a specific display interface, so that the system status, monitoring information, operation feedback, etc. 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 board separation unit, a conveying control unit 12 and a board separation control unit 13;

[0076] The programmable controller 11, serving as the "brain" of the entire feed conveyor mechanism 1, is responsible for receiving instructions from the central control unit 3 and precisely regulating the system's operation based on these instructions. It maintains a stable communication link with the central control unit 3, ensuring real-time information transmission and response between systems.

[0077] Furthermore, the conveying control unit 12 and the panel separation control unit 13, as direct subordinates of the programmable controller 11, are responsible for the precise control of the conveying unit and the panel separation unit, respectively. Both control units are connected to the programmable controller 11 via specific communication interfaces, enabling real-time monitoring and flexible regulation of the operating status of their respective units.

[0078] Specifically, the conveying control unit 12 precisely controls the conveying unit's speed, position, and other parameters according to the instructions of the programmable controller 11, ensuring that materials are accurately transported to the designated location along the predetermined path and speed. The panel separation control unit 13 is responsible for precisely controlling the panel separation unit according to the instructions to achieve effective separation and processing of materials.

[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 sophisticated 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 regulating 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. It is connected to the programmable controller 11 through the first I / O module 122. When the first photoelectric switch 121 detects a plate, it immediately sends a signal to the programmable controller 11, triggering the subsequent control process.

[0083] After receiving the detection signal from the first photoelectric switch 121, the programmable controller 11 precisely controls the speed, start, and stop of the feed conveyor motor 124 through the frequency converter 123 according to pre-set program logic. During this process, the frequency converter 123 flexibly adjusts the speed of the feed conveyor motor 124 according to the instructions from the programmable controller 11, thereby achieving precise control of the material conveying speed. Furthermore, when conveying needs to be stopped, the frequency converter 123 quickly cuts off the motor power supply according to the instructions, ensuring a smooth and safe conveying process.

[0084] In summary, through this series of sophisticated 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 this embodiment, the construction of the panel separation control unit 13 also reflects a high degree of integration and intelligence. It includes a positioning 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, the positioning module 131, a key component for determining the panel's position, establishes a stable I / O connection with the programmable controller 11 via the second I / O module 132. This connection ensures that the positioning module 131 can provide real-time feedback of the panel's position information to the programmable controller 11, providing reliable data support for subsequent precise control.

[0087] Secondly, the solenoid valve 133, a key component for controlling the on / off of the air circuit, is also connected to the programmable controller 11 via the second I / O module 132. When the first photoelectric switch 121 detects that the plate has reached the specified position, the programmable controller 11 sends a control signal to the solenoid valve 133 via 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, opening or closing the air circuit, thereby controlling the expansion and contraction of the panel separation cylinder 134. As an actuator, the precise expansion and contraction of the panel separation cylinder 134 can drive the panel separation unit to complete the panel separation operation.

[0089] In summary, through this series of sophisticated components and efficient communication mechanisms, the panel separation control unit 13 is able to achieve precise control over the panel separation process. When the first photoelectric switch 121 detects a panel, the solenoid valve 133 responds quickly, controlling 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 embodiment of this invention, the distance measuring mechanism 2 exhibits excellent performance due to its highly integrated and intelligent design. The mechanism primarily comprises a distance measuring controller 21, a second photoelectric sensor 22, a third I / O module 23, and a distance measuring light curtain 24. These components work together to achieve accurate measurement of the plate length.

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

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

[0093] Furthermore, the second photoelectric sensor 22, which detects whether the panel has reached the measurement position, establishes an I / O connection with the distance controller 21 via the third I / O module 23. When the second photoelectric sensor 22 detects that the panel has reached the specified measurement position, it immediately sends a signal to the distance controller 21, triggering the distance light curtain 24 to measure the length.

[0094] After receiving the detection signal from the second photoelectric sensor 22, the distance controller 21 activates the distance light curtain 24 to measure the length of the panel according to the preset program logic. The distance light curtain 24 uses its internal precision grating structure to accurately measure the panel length and transmits the measurement data back to the distance controller 21 in real time.

[0095] After receiving the measurement data, the distance measurement controller 21 processes and stores the data, and transmits 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. These two components work together to accurately measure the length of the plate.

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

[0099] To accurately capture this change, the second photoelectric sensor 22 is responsible for detecting whether the plate has reached the measuring area of the ranging light curtain 24. Once the second photoelectric sensor 22 detects the plate passing, it immediately sends a signal to the ranging controller 21, triggering the ranging light curtain 24 to take measurements.

[0100] After receiving the trigger signal from the second photoelectric sensor 22, the ranging controller 21 begins receiving signals from the receiver of the ranging light curtain 24. Due to the obstruction of the panel, the number of signals received by the receiver changes. This change is captured by the receiver and converted into a digital signal, which is then transmitted to the ranging controller 21.

[0101] After receiving these blockage signals, the distance controller 21 uses a preset algorithm to calculate the blockage. Based on the blockage of the signals, the distance controller 21 can accurately calculate the length of the panel within the measurement area of the distance light curtain 24, thereby achieving accurate measurement of the panel length.

[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, the ranging controller 21 uses a formula based on the working principle of the ranging light curtain 24 when calculating the length of the panel, 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 ranging controller 21 first obtains the number of obstruction signals transmitted by the ranging light curtain 24's receiver. These signals represent how many light curtain signals were blocked by the panel during the measurement process. Simultaneously, the ranging controller 21 also obtains a key parameter: the length of the interval between adjacent signals. This parameter, determined during the design and manufacture of the ranging light curtain 24, represents the physical distance between two adjacent signals on the light curtain.

[0105] After obtaining these two key parameters, the distance 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 by the number of blocked signals, the distance controller 21 can quickly and accurately calculate the length of the panel within the measurement area of the ranging light curtain 24.

[0108] It's worth noting that the accuracy of this formula depends heavily on the precision and stability of the ranging light curtain 24. Therefore, in practical applications, it's crucial to ensure that the ranging light curtain 24's receiver can accurately capture signal changes and that the intervals between adjacent signals remain constant. Only in this way can the calculated panel length be sufficiently accurate and reliable.

[0109] In summary, by using this concise and precise formula, the distance measurement controller 21 is able to quickly and accurately measure 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.
