Description

Technical Field

[0001] The present application relates to the technical field of blockboard processing, and in particular to a feeding system applied to blockboard. Background Art

[0002] During the production of blockboard, some processes require notching the ends of the core strips. For example, finger-jointed blockboard requires milling finger joints (serrated joints) at the ends of the core strips. The strips are then joined into long strips, which are then formed into boards after lamination and pressing. The quality of the finger joints in the core strips directly affects the strength, stability, and processing accuracy of the board. Finger-jointed blockboard ends must be aligned. If the finger joints are not aligned correctly, cracking and deformation may occur after gluing, requiring rework or scrapping, increasing production costs. Traditional production relies on manual visual inspection of the finger joint orientation of the strip ends and flipping core strips with different orientations to align them. However, manual fatigue or misjudgment can easily lead to misaligned strip orientations, compromising joint quality. Some automated equipment uses mechanical baffles or photoelectric sensors to detect strip position, but these cannot accurately determine the finger joint orientation of the core strips and can only detect their presence. Summary of the Invention

[0003] In view of the above problems, an embodiment of the present application provides a loading system for blockboard, which can ensure that the finger-shaped tenons of the core layer wood strips of the finger-jointed blockboard are in the same direction, thereby improving the splicing quality and production efficiency.

A spindle-shaped swing member is externally connected to the flip shaft. The two ends of the swing member are hinged to the top of the first slide plate and the top of the second slide plate, respectively. A friction wheel is provided on the bottom of the first slide plate near the side of the second slide plate. The friction wheel is connected to the driving device. The positioning device is used to adjust the position of the wood strips so that the axis of the wood strips is perpendicular to the conveying direction of the belt conveyor; The appearance recognition device is used to detect the shapes of the two ends of the wood strip to determine the direction of the wood strip; The rejecting device is used to push the wood strips in different directions out of the belt conveyor.

[0005] In some embodiments, the positioning device includes two rotating tables symmetrically arranged on both sides of the belt conveyor through a fixed block. The rotating table can be rotatably arranged on the top of the fixed block. The bottom end of the rotating table is connected to a servo motor for transmission. The outer periphery of the rotating table is provided with multiple blocking plates extending to the top of the belt conveyor at equal intervals along its circumference.

[0006] In some embodiments, protective plates for preventing the core layer wood strips from sliding are vertically provided on both side panels of the belt conveyor between the material dividing device and the positioning device.

[0007] In some embodiments, there are two swing members, and the two swing members are symmetrically arranged on both sides of the flip seat.

[0008] In some embodiments, a first U-shaped groove and a second U-shaped groove are respectively provided on the top of the first slide and the second slide, a sheath shaft is commonly connected between the two opposite inner walls of the first U-shaped groove and the second U-shaped groove, and reserved holes for the sheath shaft to pass through are respectively provided at both ends of the swinging member, the sheath shafts in the two first U-shaped grooves respectively located on the first slide and the second slide can be rotatably set in the two reserved holes of one of the swinging members, and the sheath shafts in the two second U-shaped grooves respectively located on the first slide and the second slide can be rotatably set in the two reserved holes of the other swinging member.

[0009] In some embodiments, two protrusions are formed on the bottom of the first slide near one side of the second slide, and a transmission shaft is rotatably connected between the two protrusions. One end of the transmission shaft passes through and extends to the outside of the protrusion and is coaxially connected to a rotating motor. The friction wheel is coaxially connected to the transmission shaft.

[0010] In some embodiments, there are three friction wheels, which are evenly distributed on the transmission shaft, and the outer periphery of the friction wheels is provided with anti-slip grooves.

On the other hand, the material dividing device of the present application is cleverly designed, and a telescopic member can simultaneously control the first and second slide plates to alternately move up and down and remain static. The structure is simple, efficient, and has a low failure rate. In addition, during the falling process of the first slide plate, the second slide plate is forced to rise and no longer blocks the core wood strips. During the falling process of the second slide plate, the core wood strips at the rear can be prevented from continuing to move forward, and after the first slide plate falls, the friction wheel will rub against a core wood strip closest to the dividing device, causing it to move forward quickly and then separate from the dividing device. In this way, multiple core wood strips on the belt conveyor can be separated, so that there is enough gap between two adjacent core wood strips on the belt conveyor, avoiding the problem that the appearance recognition device cannot accurately recognize the core wood strips due to accumulation or close arrangement, thereby facilitating the operation of subsequent positioning devices, appearance recognition devices, and rejection devices.

[0017] The following will describe in detail the embodiments of the technical solution of the present application in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only used as examples and cannot be used to limit the scope of protection of the present application.

[0018] Specifically, please refer to Figures 1 to 4 . Figure 1 This is a schematic diagram of the overall structure of the device provided in the embodiment of the present application. Figure 2 A schematic diagram of a local structure provided in an embodiment of the present application, Figure 3 This is a schematic diagram of the partial structure of the material distribution device provided in the embodiment of the present application. Figure 4Schematic diagram of a partial explosion structure of a material separation device provided in an embodiment of the present application. The feeding system 100 applied to blockboard includes a belt conveyor 110 and a material separation device 120, a positioning device 130, an appearance recognition device 140, and a rejection device 150 arranged in sequence along the conveying direction of the belt conveyor 110, wherein the belt conveyor 110 is used to convey core wood strips 200, and the core wood strips 200 will pass through the material separation device 120, the positioning device 130, the appearance recognition device 140, and the rejection device 150 in sequence under the conveyance of the belt conveyor 110. The material separation device 120 is used to separate the multiple core wood strips 200 on the belt conveyor 110, so that there is sufficient gap between two adjacent core wood strips 200 on the belt conveyor 110, thereby facilitating the subsequent operation of various components. The positioning device 130 is used to adjust the position of the wood strips so that the axial direction of the core wood strips 200 is perpendicular to the conveying direction of the belt conveyor 110. The appearance recognition device 140 is used to detect the shapes of the two ends of the wood strips to determine whether the directions of the wood strips are consistent (such as Figure 5 The two core layer wood strips 200 are in opposite directions), and the rejecting device 150 is used to push the wood strips in different directions out of the belt conveyor 110.

[0019] The material distribution device 120 includes a first connecting seat 121 and a second connecting seat 122. The second connecting seats 122 are two and symmetrically arranged on both sides of the belt conveyor 110. A slide plate 123 is horizontally arranged between the two second connecting seats 122. The slide plate 123 has two parallel sliding grooves 124. A first slide plate 125 and a second slide plate 126 are respectively slidably arranged in the two sliding grooves 124. The size of the sliding grooves 124 should be larger than the cross-sectional dimensions of the first slide plate 125 and the second slide plate 126 to ensure that the first slide plate 125 and the second slide plate 126 can slide relatively smoothly within the sliding grooves 124 and have a certain amount of space for flipping and deformation. A flip shaft 127 is commonly connected between the two second connecting seats 122. The flip shaft 127 is located between the first slide plate 125 and the second slide plate 126. The two ends of the flip shaft 127 can be connected to the two second connecting seats 122 via bearing seats. A pivot seat 127a is fixed to the center of the pivot shaft 127. A telescopic member 128 is connected to the first connecting seat 121 via a rotating support. The free end of the telescopic member 128 is hinged to the pivot seat 127a. The telescopic member 128 can be an electric telescopic rod, pneumatic, or other telescopic mechanism. During extension and retraction, the telescopic member 128 drives the pivot shaft 127 through the pivot seat 127a, with the two rotations occurring in opposite directions. A spindle-shaped swinging member 129 is attached to the outer surface of the pivot shaft 127. Rotation of the pivot shaft 127 also drives the swinging member 129 to rotate synchronously with the rotation of the pivot shaft 127. The two ends of the swing member 129 are respectively hinged to the top of the first slide 125 and the second slide 126. During the rotation of the swing member 129 along the flip shaft 127, its two ends will alternately rise and fall (similar to a seesaw) according to the different rotation directions, thereby driving the first slide 125 and the second slide 126 to alternately rise or fall (since the axis of the swing member 129 is perpendicular to the flip sweep arc at the end in the initial flip position, its movement is mainly vertical movement, and the lateral displacement is very small). A friction wheel 125a is provided at the bottom of the first slide plate 125, near one side of the second slide plate 126. The friction wheel 125a is connected to a driving device, which may be a motor. After the motor drives the friction wheel 125a to rotate, if the friction wheel 125a contacts the core wood strip 200, the core wood strip 200 will be quickly thrown forward. The rotation frequency of the friction wheel 125a should be set according to the material of the friction wheel 125a and the size of the core wood strip 200. If the rotation frequency of the friction wheel 125a is too low, the core wood strip 200 cannot be thrown forward quickly or the throwing distance is insufficient. If the rotation frequency of the friction wheel 125a is too high, the core wood strip 200 will be thrown too far and will fall off the belt conveyor 110. In the embodiment of the present application, during operation, the core wood strips 200 are conveyed on the belt conveyor 110. At this time, the telescopic member 128 is in an extended state. The flip shaft 127 and the friction wheel 125a rotate in a clockwise direction, so that the second slide plate 126 remains in a falling state and the first slide plate 125 remains in a lifted state. At this time, the bottom of the second slide plate 126 is close to the upper belt of the belt conveyor 110 (a gap is left between the bottom end of the second slide plate 126 and the upper belt of the belt conveyor 110 to avoid friction while ensuring that the belt conveyor 110 continues to operate). The core wood strips 200 are blocked by the second slide plate 126 during transportation and are arranged in sequence on the left side of the second slide plate 126 (the core wood strips 200 are lighter in weight, and the belt below them is at the bottom of the same core wood strips 200). The first slide 125 is pressed down by the swinging member 129 until the friction wheel 125a contacts the rightmost core wood strip 200, and the rightmost core wood strip 200 is quickly moved forward and leaves the material distribution device 120 due to the rotation of the friction wheel 125a and the friction on the core wood strip 200. Subsequently, the telescopic member 128 is quickly extended and reset, and the second slide 126 falls and resets to continue to block the multiple core wood strips 200 moving from its left side. After the first slide 125 moves up and resets, the friction wheel 125a is away from the zinc layer wood strips below.

[0020] The core wood strips 200 are arranged on the belt conveyor 110 at a certain interval by continuously circulating. Subsequently, the core wood strips 200 will enter the positioning device 130 after leaving the material distribution device 120. Since the core wood strips 200 are driven by the friction wheel 125a in the material distribution device 120 and then accelerated forward, their angles will change (the original length direction of the core wood strips 200 is perpendicular to the conveying direction of the belt conveyor 110. At this time, due to the different forward distances of the two ends of the core wood strips 200, the axial direction of the core wood strips 200 may rotate, such as Figure 1The positioning device 130 can adjust the position of the wood strip so that the length direction of the wood strip is perpendicular to the conveying direction of the belt conveyor 110, and then the core wood strip 200 enters under the appearance recognition device 140. The appearance recognition device 140 is a prior art, which can take pictures and recognize the images of the two ends of the core wood strip 200, and compare the image with the image input in advance into its processor 142, so as to identify the core wood strip 200 with inconsistent end finger-shaped tenon directions. The subsequent rejection device 150 pushes the core wood strip 200 with inconsistent end finger-shaped tenon directions off the belt conveyor 110.

[0021] As described above, the material dividing device 120, the positioning device 130, the appearance recognition device 140, and the rejection device 150 and other components can all be centrally controlled by the PLC to achieve automation and efficient linkage. For example, when the appearance recognition device 140 detects that the end finger-shaped tenons of the core wood strip 200 are inconsistent in direction, the appearance recognition device 140 transmits an electrical signal to the PLC, and the PLC further sends an instruction to the rejection device 150. After receiving the instruction, the rejection device 150 delays for a period of time according to the transmission speed of the belt conveyor 110. After the core wood strip 200 enters its range of action, the rejection device 150 operates to push the core wood strip 200 out of the belt conveyor 110. The PLC can also control the action interval and action duration between each component to avoid the core wood strip 200 from being blocked or interfering with the belt conveyor 110.

[0022] As can be seen from the above, in the embodiment of the present application, by arranging the material dividing device 120, the positioning device 130, the appearance recognition device 140, and the rejection device 150 and other components to cooperate with each other, the zinc-layer wood boards with inconsistent finger-shaped tenons at the end can be pushed out of the belt conveyor 110, thereby ensuring that the finger-shaped tenons of the core wood strips 200 of the finger-jointed thin-walled wood boards are in the same direction, thereby improving the subsequent splicing quality and production efficiency. On the other hand, the material dividing device 120 of the present application is cleverly designed. Through a telescopic member 128, the first slide 125 and the second slide 126 can be simultaneously controlled to alternately move up and down and remain static. The structure is simple, efficient, and has a low failure rate. In addition, during the falling process of the first slide 125, the second slide 126 is forced to rise and no longer blocks the core wood strips 200. During the falling process of the second slide 126, the rear core wood strips 200 can be blocked from continuing to move forward, and after the first slide 125 falls, the friction wheel 125a will rub against a core wood strip 200 closest to the dividing device 120, causing it to move forward quickly and then separate from the dividing device 120. In this way, the multiple core wood strips 200 on the belt conveyor 110 can be separated, so that there is enough gap between the two adjacent core wood strips 200 on the belt conveyor 110, avoiding the problem that the appearance recognition device 140 cannot accurately recognize the core wood strips 200 due to accumulation or close arrangement, thereby facilitating the operation of subsequent positioning devices 130, appearance recognition devices 140 and rejection devices 150 and other components.

[0023] In some embodiments, please refer to Figure 5 , Figure 5 A schematic diagram of the partial structure of the positioning device provided in an embodiment of the present application. The positioning device 130 includes two rotating platforms 132 symmetrically arranged on either side of the belt conveyor 110 via a fixed block 131. The rotating platforms 132 are rotatably mounted on top of the fixed block 131. The bottom end of the rotating platforms 132 is connected to a servo motor 133. Multiple blocking plates 134 are evenly spaced along the outer periphery of the rotating platforms 132, extending to the top of the belt conveyor 110.

[0024] For the convenience of explanation, the present application provides a specific setting method of the positioning device 130. During operation, the two servo motors 133 operate synchronously. After the servo motor 133 is turned on, it will drive the rotating platform 132 to rotate, so that one of the blocking plates 134 extends to the top of the belt conveyor 110 and is perpendicular to the conveying direction of the belt conveyor 110 and remains. At this time, the core layer wood strips 200 that have been separated by the separating device 120 in front will move under the drive of the belt conveyor 110. If the core layer wood strips 200 are in an inclined state, their first end (the end closer to the front) will preferentially contact one of the blocking plates 134 on one side and be restricted in displacement. , the second end continues to move forward without restriction. At this time, the core wood strip 200 will rotate until the second end is also blocked by another blocking plate 134. At this time, the two ends of the core wood strip 200 are almost flush, and the flipping angle of the core wood strip 200 will be corrected. The length direction of the core wood strip 200 is close to perpendicular to the conveying direction of the belt conveyor 110, thereby facilitating the subsequent appearance recognition device 140 to accurately locate the end of the core wood strip 200. Since the flipping angle of the core wood strip 200 will be corrected, the size of the space where its end is located will be greatly reduced when it passes through the appearance recognition device 140, thereby reducing the camera area positioning and reducing the amount of data processing.

[0025] In some embodiments, please refer again to Figure 1 On both side panels of the belt conveyor 110, between the material dividing device 120 and the positioning device 130, protective plates are vertically provided to prevent the core wood strips 200 from sliding off. In the embodiment of the present application, the protective plates are provided to prevent the core wood strips 200 from being thrown to the sides of the belt conveyor 110 during the process of rapid forward movement driven by the friction wheel 125a. At the same time, the positions of the ends of the core wood strips 200 are restricted so that their ends do not exceed the inner position of the protective plates, thereby preventing the ends of the core wood strips 200 from extending outside the belt conveyor 110 and preventing the positioning device 130 from being able to capture the core wood strips 200.

[0026] In some embodiments, please refer again to Figure 3 and Figure 4 There are two swing members 129, which are symmetrically arranged on both sides of the flip seat 127a. In the embodiment of the present application, by providing two swing members 129, the swing members 129 can apply force to the first slide 125 and the second slide 126 more stably, thereby improving the stability of the device during operation.

[0027] In some embodiments, please refer to Figure 4A first U-shaped groove 126a and a second U-shaped groove 126b are respectively formed on the top of the first slide 125 and the second slide 126. A sheath shaft 126c is commonly connected between the two opposite inner side walls of the first U-shaped groove 126a and the second U-shaped groove 126b. Both ends of the swinging member 129 are respectively provided with reserved holes 129a for the sheath shaft 126c to pass through. The sheath shaft 126c located in the two first U-shaped grooves 126a on the first slide 125 and the second slide 126 can be rotatably set in the two reserved holes 129a of one of the swinging members 129, and the sheath shaft 126c located in the two second U-shaped grooves 126b on the first slide 125 and the second slide 126 can be rotatably set in the two reserved holes 129a of the other swinging member 129. In the embodiment of the present application, a connection method between the first slide 125, the second slide 126 and the swing member 129 is provided. Specifically, in the working state, when the swing member 129 flips, the sheath shaft 126c inside the reserved hole 129a will be driven synchronously, and then the sheath shaft 126c will drive the first slide 125 and the second slide 126 to move up or down. In the embodiment of the present application, the size of the reserved hole 129a is larger than the size of the sheath shaft 126c, so that the sheath shaft 126c can rotate smoothly in the reserved hole 129a.

[0028] In some embodiments, please refer to Figure 4 . Two protruding blocks 125b are formed on the bottom of the first slide 125, near the side of the second slide 126. A transmission shaft 125c is rotatably connected between the two protruding blocks 125b. One end of the transmission shaft 125c passes through and extends to the outside of the protruding block 125b and is coaxially connected to the rotating motor 125d. The friction wheel 125a is coaxially connected to the transmission shaft 125c. In the embodiment of the present application, during operation, after the rotating motor 125d is turned on, it will drive the transmission shaft 125c to rotate, and further the transmission shaft 125c drives the friction wheel 125a to rotate. It should be noted that in the embodiment of the present application, the size of the two protruding blocks 125b needs to meet the requirement that when the first slide 125 and the second slide 126 are tilted at a small angle in the sliding groove 124, a certain gap is still retained between the friction wheel 125a and the second slide 126.

[0029] In some embodiments, please refer to Figure 4There are three friction wheels 125a, which are evenly distributed on the transmission shaft 125c. The outer periphery of the friction wheels 125a is provided with anti-slip grooves. In the embodiment of the present application, through the above-mentioned arrangement, the three friction wheels 125a can be synchronously driven by the rotating motor 125d, and then the three friction wheels 125a can act on the core wood strips 200 more evenly, thereby avoiding the tilting state caused by the imbalance of force on the core wood strips 200 caused by the inability of a single friction wheel 125a to accurately act on the middle of the core wood strips 200, and reducing the offset angle of the core wood strips 200 when being pushed forward.

[0030] In some embodiments, please refer to Figure 6 , Figure 6 This is a partial structural diagram of the appearance recognition device and the rejection device provided in an embodiment of the present application. The rejection device 150 includes a material guide trough 151 and a push rod component symmetrically arranged on both sides of the belt conveyor 110. The bottom plate of the material guide trough 151 gradually tilts downward in the direction away from the belt conveyor 110. The push rod component includes an electric push rod 152 arranged in a horizontal direction. The free end of the electric push rod 152 is connected to a push plate 153. The axial direction of the electric push rod 152 is perpendicular to the conveying direction of the belt conveyor 110. For the convenience of explanation, a specific setting method of the rejection device 150 is provided in an embodiment of the present application. During operation, the electric push rod 152 quickly extends and drives the push plate 153 forward, so that the push plate 153 acts on the core wood strips 200 in a horizontal direction. Subsequently, the core wood strips 200 slide to the material guide trough 151 under the action of inertia and finally fall along the material guide trough 151 and are collected.

[0031] In some embodiments, please refer again to Figure 6 The appearance recognition device 140 includes an imaging device 141 and a processor 142 electrically connected to each other. Two imaging devices 141 are provided, one above each side of the conveyor belt 110. In this embodiment, the processor 142 can be a Raspberry Pi 4 with OpenCV, and the imaging device 141 can be a Basler ace2 (5-megapixel). In this application, the two imaging devices 141 correspond to the two ends of the core wood strip 200, respectively, allowing detection at both ends to avoid omissions.
