Description

Technical Field

[0001] The invention relates to the technical field of plate processing and conveying, in particular to a solid wood plate processing and feeding device. Background Art

[0002] In a solid wood processing workshop, loading and unloading of boards is a key link in the production process. The traditional way of loading and unloading boards mainly relies on manual operation, which is not only inefficient but also has safety hazards. Workers need to frequently move boards, which not only consumes a lot of physical energy, but also easily causes damage or deformation of the boards during the transportation process. In addition, due to the uncontrollability of manual operation, it is often difficult to unify the loading and unloading time of boards, which will also affect the utilization rate and production efficiency of subsequent processing equipment.

[0003] With the continuous development of automation technology, more and more workshops have begun to use automated equipment for loading and unloading of plates. However, most of the existing automated plate loading and unloading equipment have the problems of single function and poor adaptability. In addition, the moisture content of the plate is controlled within a certain range (usually 8%~10%) to reduce the deformation and cracking of the plate during processing and use. The existing devices can often only complete simple plate handling tasks, but cannot monitor and control key parameters such as the moisture content of the plate in real time. This results in the need for manual screening and classification of the plates during the processing process, which increases production costs and time costs. Summary of the invention

[0004] The purpose of the present invention is to provide a solid wood board processing and loading device, which solves the problem that the existing device can only load and unload but cannot remove boards with unqualified moisture content.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a solid wood board processing and feeding device, comprising a material box, a lifting plate is arranged inside the material box, the boards are stacked on the lifting plate, and each time the lifting plate rises, the boards are lifted by a thickness unit height, two weighing bars are symmetrically arranged on both sides of the port of the material box, and clamping bars are connected to the opposite surfaces of the two weighing bars, and gravity sensors are arranged in the clamping bars. When the two weighing bars are close to each other, the boards are clamped to a fixed locking force, and then the two weighing bars are synchronously moved up to weigh the boards;

[0006] On both sides of the port of the material box are the discharging end and the pushing end respectively. A swing plate is hinged to the discharging end, and a pushing mechanism is arranged at the pushing end. Vertically arranged on one side of the discharging end are a conveyor belt, a first guiding plate and a second guiding plate. The conveyor belt is connected to subsequent processing equipment. The first guiding plate is used for conveying the boards with too low water content, and the second guiding plate is used for conveying the boards with too high water content. The swing plate swings with the measured value of the gravity sensor. Moreover, the swing plate can swing to a first angle, a second angle and a third angle. When the swing plate swings to the first angle, it is flush with the conveyor belt; when it swings to the second angle, it is flush with the first guiding plate; when it swings to the third angle, it is flush with the second guiding plate.

[0007] The weighed value of the board is m, and the swing plate swings with the set weighing value of the gravity sensor. The set weighing value is from m1 to m2. When m1 ≤ m ≤ m2, the swing plate swings to the first angle; when m < m1, the swing plate swings to the second angle; when m2 < m, the swing plate swings to the third angle.

The two racks jointly engage with a gear. A rotating shaft is connected to the gear through a magnetic coupler. A first arc-shaped air cylinder is connected to the N-shaped frame. The output end of the first arc-shaped air cylinder is connected to the rotating shaft. When the first arc-shaped air cylinder extends, it pushes the rotating shaft to rotate. And when the rotational torque of the rotating shaft exceeds the coupling force of the magnetic coupler, the rotating shaft rotates relative to the gear, so that the two weighing bars approach each other and clamp the board with a fixed locking force.

[0009] Preferably, two groups of lifting air cylinders are symmetrically connected to both sides of the material box. Sliding seats are connected to both sides of the N-shaped frame. The output ends of the lifting air cylinders are slidably connected to the sliding seats.

[0011] Preferably, a second arc-shaped air cylinder is connected to the side wall of the material box. The output end of the second arc-shaped air cylinder is connected to the swing plate. The second arc-shaped air cylinder expands and contracts with the weighed value m of the board to make the swing plate swing.

[0012] Preferably, the pushing mechanism includes a mounting plate connected to the pushing end, a rotating rod is rotatably connected to the mounting plate, an electric telescopic rod is radially connected to the rotating rod, a pushing block is slidably connected to the mounting plate, a connecting rod is hinged between the output end of the electric telescopic rod and the pushing block, the rotating rod swings back and forth within ninety degrees, so that the pushing block pushes the plate to move toward the discharging end, and when the pushing block moves toward the direction of the plate, the first arc cylinder is shortened, thereby releasing the clamping of the weighing bar on the plate.

[0013] Preferably, the connecting rod comprises a first rectangular rod, a rectangular tube and a second rectangular rod, one end of the second rectangular rod is hinged to the pusher block, the other end of the second rectangular rod is fixedly connected to the rectangular tube, one end of the first rectangular rod is hinged to the output end of the electric telescopic rod, and the other end of the first rectangular rod is slidably connected to the rectangular tube;

[0014] The electric telescopic rod extends as the swing plate swings, and when the swing plate swings continuously, the electric telescopic rod extends continuously, and after the electric telescopic rod extends and when the swing plate maintains the first angle, the electric telescopic rod shortens to the shortest state.

[0015] Preferably, the rectangular tube is connected with an air pipe, and the air pipe is provided with a solenoid valve, and when the electric telescopic rod is in a telescopic state, the solenoid valve is opened.

[0016] Preferably, two supporting legs are connected to one side of the lower surface of the material box, and two rectangular hydraulic rods are arranged on the other side of the lower surface of the material box; when the swing plate swings to a first angle, the rectangular hydraulic rod is in a fully extended state, so that the plate is pushed to the conveyor belt; when the swing plate swings to a second angle, the rectangular hydraulic rod is shortened to a first length, so that the material box is tilted, so that the plate is pushed to the first material guide plate; when the swing plate swings to a third angle, the rectangular hydraulic rod is shortened to a second length, so that the material box is tilted, so that the plate is pushed to the second material guide plate.

[0017] Preferably, two straight hydraulic rods are fixedly connected to the lower surface of the material box, the output ends of the two straight hydraulic rods are respectively hinged to the output ends of the two rectangular hydraulic rods, and the straight hydraulic rods and the rectangular hydraulic rods are extended and retracted synchronously.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention sets a weighing bar and a gravity sensor. The device can accurately measure the weight of the plate and judge whether the moisture content of the plate is qualified according to a preset weight range. This precise screening mechanism ensures that only plates with moderate moisture content and stable quality will be sent to subsequent processing equipment, thereby improving the overall quality of the product. According to the different moisture contents of the plates, the swing plate can swing to different angles to transport the plates to different processing paths respectively. This flexible processing method enables unqualified plates to be processed in a timely and appropriate manner, avoiding waste of resources and damage to processing equipment. By screening out plates with too high or too low moisture content in advance and performing corresponding treatments on them (such as humidification or continued drying), the device helps to reduce problems such as cracking and deformation that may occur in subsequent processing, thereby improving processing efficiency and product qualification rate.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Referring to Figure 1-Figure 6 , this embodiment provides a technical solution: a feeding device for solid wood board processing, including a material box 1. An elevating plate 12 is arranged inside the material box 1, and the boards are stacked on the elevating plate 12. Each time the elevating plate 12 rises, it lifts the boards by a thickness unit height. Two weighing bars 23 are symmetrically arranged on both sides of the port of the material box 1. Clamping bars 25 are connected to the opposite surfaces of the two weighing bars 23. Gravity sensors are arranged inside the clamping bars 25. When the two weighing bars 23 approach each other, they clamp the boards with a fixed locking force, and then the two weighing bars 23 move upward synchronously to weigh the boards; the two sides of the port of the material box 1 are respectively a discharging end and a pushing end. A swing plate 33 is hinged at the discharging end, and a pushing mechanism is arranged at the pushing end. A conveyor belt 3, a first guiding plate 31, and a second guiding plate 32 are vertically arranged on one side of the discharging end. The conveyor belt 3 is connected to subsequent processing equipment. The first guiding plate 31 is used to convey the boards with too low water content, and the second guiding plate 32 is used to convey the boards with too high water content. The swing plate 33 swings according to the measured value of the gravity sensor. Moreover, the swing plate 33 can swing to a first angle, a second angle, and a third angle. When the swing plate 33 swings to the first angle, it is flush with the conveyor belt 3; when it swings to the second angle, it is flush with the first guiding plate 31; when it swings to the third angle, it is flush with the second guiding plate 32; the weighed value of the board is m, and the swing plate 33 swings according to the set weighing value of the gravity sensor. The set weighing value is from m1 to m2. When m1 ≤ m ≤ m2, the swing plate 33 swings to the first angle; when m < m1, the swing plate 33 swings to the second angle; when m2 < m, the swing plate 33 swings to the third angle.

[0029] In use, stack the plates in the bin 1. The lifting plate 12 receives the plates in the bin 1. After the lifting hydraulic rod 11 extends to raise the lifting plate 12 by a height equal to the thickness of one plate, the top plate is above the port of the bin 1. The pushing mechanism can push this plate to the discharge end to complete the feeding of the plate. Before the feeding of the plate, the two weighing bars 23 approach and squeeze each other on both sides of the top plate, so that each plate moving to the top is subjected to the same locking force. At this time, the clamping bars 25 are in close contact with both ends of the plate. Subsequently, the two weighing bars 23 move up synchronously, so that the gravity sensors in the clamping bars 25 weigh the weight of the clamped plate. Among them, a standard range value is preset for the weight of the plate according to the size of the plate. Set this range value to m1 to m2. When the moisture content of the weighed plate is qualified, the weight of the plate is m1 ≤ m ≤ m2. At this time, the plate is conveyed to the conveyor belt 3 and conveyed by the conveyor belt 3 to the subsequent processing equipment for processing. When the moisture content of the plate is too low, that is, m < m1, at this time, the swing plate 33 swings to the second angle, and at this time, the plate is conveyed away by the first guide plate 31 without subsequent processing, and the plate needs to be humidified. When the moisture content of the plate is too high, the swing plate 33 swings to the third angle, and then the plate is conveyed away by the second guide plate 32 for subsequent continuous drying;

[0030] In the above, the whole clamping bar 25 or the contact part with the plate is provided with a flexible material, such as a rubber block, to prevent the plate from being deformed by clamping;

[0031] Through the above settings, it is possible to pick out the plates with too high or too low moisture content when the plates are being fed and processed, ensuring that the plates will not crack or deform during or after subsequent processing.

[0032] An N-shaped frame 2 is provided above the port of the bin 1. Two racks 24 are symmetrically and slidably connected to the side of the N-shaped frame 2 facing the bin 1. The two racks 24 are respectively connected to the two weighing bars 23. The two racks 24 are jointly engaged with a gear 28. A rotating shaft 29 is connected to the gear 28 through a magnetic coupler. A first arc-shaped cylinder 291 is connected to the N-shaped frame 2. The output end of the first arc-shaped cylinder 291 is connected to the rotating shaft 29. When the first arc-shaped cylinder 291 extends, it pushes the rotating shaft 29 to rotate, and when the rotational torque of the rotating shaft 29 exceeds the coupling force of the magnetic coupler, the rotating shaft 29 rotates relative to the gear 28, so that the two weighing bars 23 approach each other and clamp the plate with a fixed locking force.

[0033] The rack 24 can slide relative to the N-shaped frame 2, but when the N-shaped frame 2 moves up and down, it can drive the rack 24 and the gear 28 to move up and down synchronously, ensuring that the clamped plate can be lifted for weighing later. When the plate needs to be locked, the first arc cylinder 291 extends, so that the rotating shaft 29 is pushed and rotates, so that the gear 28 is driven to rotate to drive the two racks 24 to drive the two weighing bars 23 to approach each other to clamp the plate. The coupling force of the magnetic coupler is fixed, so when the torque applied to the rotating shaft 29 reaches the coupling force, the rotating shaft 29 can no longer drive the two weighing bars 23 to approach each other, so that the clamping force of the two weighing bars 23 each time they clamp the plate is fixed, ensuring that there is no interference with subsequent weighing.

[0034] Two groups of lifting cylinders 26 are symmetrically connected to both sides of the material box 1 , and slide seats 27 are connected to both sides of the N-shaped frame 2 . The output ends of the lifting cylinders 26 are slidably connected to the slide seats 27 .

[0035] When the two groups of lifting cylinders 26 are extended, they can drive the N-shaped frame 2 to move upward through the slide 27, so that the N-shaped frame 2 drives the two weighing bars 23 to move upward, so that the plate clamped by the two weighing bars 23 moves upward and is weighed. The setting of the slide 27 can compensate for the axial position deviation of the lifting cylinder 26 during extension and retraction, ensuring that the N-shaped frame 2 can be lifted stably.

[0036] An L-shaped rod 21 is connected to the N-shaped frame 2, and an inserting tube 22 for inserting the L-shaped rod 21 is provided on the material box 1.

[0037] The cooperation between the L-shaped rod 21 and the insert tube 22 prevents the N-shaped frame 2 from swinging relative to the material box 1, and can only be raised and lowered relative to the material box 1, ensuring that the clamped plate can be directly above the port of the material box 1, so that the rear plate can be accurately pushed to the discharge end.

[0038] A second arc cylinder 34 is connected to the side wall of the material box 1, and the output end of the second arc cylinder 34 is connected to the swing plate 33. The second arc cylinder 34 expands and contracts with the weighing value m of the plate material to make the swing plate 33 swing.

[0039] The swing of the swing plate 33 is driven by the extension and contraction of the second arc cylinder 34, and the extension and contraction length of the second arc cylinder 34 is executed according to the weight m of the measured plate, ensuring that the swing plate 33 can swing to the first angle, the second angle or the third angle according to demand.

[0040] The pushing mechanism includes a mounting plate 5 connected to the pushing end, a rotating rod 51 is rotatably connected to the mounting plate 5, an electric telescopic rod 52 is radially connected to the rotating rod 51, a pushing block 57 is slidably connected to the mounting plate 5, a connecting rod is hinged between the output end of the electric telescopic rod 52 and the pushing block 57, the rotating rod 51 swings back and forth within ninety degrees, so that the pushing block 57 pushes the plate to move toward the discharge end, and when the pushing block 57 moves toward the plate, the first arc cylinder 291 shortens, thereby releasing the clamping of the weighing bar 23 on the plate.

[0041] The mounting plate 5 allows the pushing mechanism to be installed, and the rotating rod 51 is driven by an external motor to swing back and forth within ninety degrees. When the plate is weighed and the clamping is released, the rotating rod 51 drives the electric telescopic rod 52 to swing toward the direction of the material box 1, so that the electric telescopic rod 52 pushes the pushing block 57 to move toward the plate through the connecting rod, and pushes the plate to the discharge end of the material box 1. The pushing block 57 is connected to the mounting plate 5 through a slider 58. The slider 58 has a sufficient length so that the slider 58 will not separate from the mounting plate 5 when the pushing block 57 slides, thereby ensuring that the running trajectory of the pushing block 57 will not deviate.

[0042] The connecting rod includes a first rectangular rod 53, a rectangular tube 55 and a second rectangular rod 54, one end of the second rectangular rod 54 is hinged to the push block 57, the other end of the second rectangular rod 54 is fixedly connected to the rectangular tube 55, one end of the first rectangular rod 53 is hinged to the output end of the electric telescopic rod 52, and the other end of the first rectangular rod 53 is slidably connected in the rectangular tube 55; the electric telescopic rod 52 extends as the swing plate 33 swings, and the electric telescopic rod 52 extends continuously when the swing plate 33 swings continuously, and after the electric telescopic rod 52 is extended and the swing plate 33 maintains the first angle, the electric telescopic rod 52 is shortened to the shortest state.

[0043] In order to make up for the feeding gap on the conveyor belt 3 after the unqualified plates are removed, each time the swing plate 33 swings, it indicates that the moisture content of the pushed out plate is unqualified. At this time, the electric telescopic rod 52 is extended, so that the distance of the subsequent plates being pushed out is increased, ensuring that the gap between the plates on the conveyor belt 3 is not too large, thereby ensuring the continuity of the subsequent plate processing;

[0044] If the swing plate 33 swings continuously, it means that the plates with unqualified moisture content are continuously removed, and when the swing plate 33 swings continuously, the electric telescopic rod 52 is continuously extended, so that the first pushing distance of the plates that can be pushed onto the conveyor belt 3 next time is further increased, ensuring that the spacing between the plates on the conveyor belt 3 is not too large;

[0045] If the swing plate 33 is stationary at the first angle position after continuous swinging and remains stationary until the second plate is about to be pushed out, it means that the moisture content of the subsequent plate is qualified. At this time, the electric telescopic rod 52 is shortened to ensure that the subsequent plate pushed onto the conveyor belt 3 will not be too close to or touch the previous plate;

[0046] When the electric telescopic rod 52 is extended, the first rectangular rod 53 slides in a direction away from the rectangular tube 55, so that the connecting rod is lengthened and the remaining components are not interfered.

[0047] The rectangular tube 55 is connected to an air pipe 56 , and an electromagnetic valve is provided on the air pipe 56 . When the electric telescopic rod 52 is in a telescopic state, the electromagnetic valve is opened.

[0048] When the electric telescopic rod 52 is extended or retracted, the first rectangular rod 53 slides in the rectangular tube 55. At this time, the solenoid valve is opened to ensure the balance of air pressure inside and outside the rectangular tube 55. When the electric telescopic rod 52 stops extending or retracting, the solenoid valve is closed to ensure that the connecting rod maintains its current length state.

[0049] Two supporting legs 4 are connected to one side of the lower surface of the material box 1, and two rectangular hydraulic rods 42 are arranged on the other side of the lower surface of the material box 1. When the swing plate 33 swings to the first angle, the rectangular hydraulic rod 42 is in a fully extended state, so that the plate is pushed to the conveyor belt 3. When the swing plate 33 swings to the second angle, the rectangular hydraulic rod 42 shortens to the first length, so that the material box 1 tilts, so that the plate is pushed to the first guide plate 31. When the swing plate 33 swings to the third angle, the rectangular hydraulic rod 42 shortens to the second length, so that the material box 1 tilts, so that the plate is pushed to the second guide plate 32.

[0050] In order to make it unnecessary to set a longer length for the swing plate 33 to overlap the positions of the conveyor belt 3, the first guide plate 31 and the second guide plate 32, when the swing plate 33 swings to the first angle, the rectangular hydraulic rod 42 does not shorten, and the conveyed plate is in a horizontal state at this time, and can be stably pushed to the conveyor belt 3, and when the swing plate 33 swings to the second angle, the rectangular hydraulic rod 42 shortens to the first length state, in which the plate is inclined and its surface is close to being parallel to the surface of the first guide plate 31, so that it can be pushed to the first guide plate 31, and when the swing plate 33 swings to the third angle, the rectangular hydraulic rod 42 shortens to the second length, as described above, so that the plate can be conveyed to the second guide plate 32;

[0051] The rectangular hydraulic rod 42 is shortened and then restored to a fully extended state, so that the material box 1 remains vertical, thereby ensuring that the subsequent weighing of the plate is not affected. The rectangular hydraulic rod 42 can be reset after the push block 57 is fully restored. A position sensor is set to detect that the rectangular hydraulic rod 42 is extended to a full state after the push block 57 is reset.

[0052] Two straight hydraulic rods 41 are fixedly connected to the lower surface of the material box 1 , and the output ends of the two straight hydraulic rods 41 are respectively hinged to the output ends of two rectangular hydraulic rods 42 , and the straight hydraulic rods 41 and the rectangular hydraulic rods 42 are synchronously extended and retracted.

[0053] In order to ensure that the rectangular hydraulic rod 42 can be extended and retracted so that the position of the material box 1 relative to the ground will not deviate too much when the material box 1 is tilted, a straight hydraulic rod 41 is also arranged at the lower part of the material box 1. The output ends of the straight hydraulic rod 41 and the rectangular hydraulic rod 42 are hinged to each other and the two are extended and retracted synchronously, so that the material box 1 can still obtain sufficient supporting force after being tilted, and it is ensured that the moving distance of the material box 1 relative to the ground will not be too large.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
