[0014] The present invention also discloses a method for stacking furniture processing plates, which uses the above-mentioned equipment for stacking furniture processing plates, and comprises the following steps:

[0015] S1: First place the support frame at one end of the plate conveyor belt so that the guide roller and the conveyor belt are at the same level;

[0016] S2: Operate the correction limit unit according to the length and width of the plate, place the plate placement plate on the top of the support pallet, and move the plate completely onto the guide roller as the conveyor belt operates;

[0017] S3: Start the telescopic cylinder, and the side connecting pressure plate drives the movable frame to move downward by contracting the telescopic cylinder. In this process, the plate is made to fall to the top of the plate placing plate by the pressure plate shifting member. In this process, the plate is made to fall to the top of the plate placing plate by the cooperation of the pressure plate shifting member and the one-way reset member, and the supporting plate is moved downward at the same time. Then, the guide roller is restored by extending the movable frame. In this process, the plate placed on the top of the plate placing plate is limited by the correction limit unit;

[0018] S4: When the subsequent plates fall onto the guide rollers, the telescopic cylinder is started again, so that when the telescopic cylinder contracts, the plates fall onto the top of the plate placement plate through the pressure plate shifting member, so as to prevent the plates from being damaged by friction during stacking;

[0019] S5: After the stacking of the plates is completed, the stacked plates and the plate placement plate are removed from the top of the self-supporting pallet.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By setting the pressure plate shifting part, the guide roller moves down when the telescopic cylinder contracts. At this time, the pressure roller will press the plate placed on the top of the plate placing plate. At the same time, the positioning column drives the guide roller to move in the opposite direction along the positioning guide frame, so that the plate on the guide roller can be stacked with the plate on the plate placing plate due to the loss of support from the guide roller. When the positioning column moves to the top of the triangular stop block, the positioning column will shrink and recover under the action of the elastic restoring force of the second telescopic spring. At this time, the guide roller moves to the initial position with the extension of the telescopic cylinder, and then the plate on the conveyor belt will fall onto the guide roller again. This can be repeated to achieve stacking between plates, preventing large-area friction between plates during the stacking process, thereby preventing the plates from being damaged during the stacking process;

[0022] 2. By setting the correction limit unit, the distance between the T-type sleeve blocks is adjusted to be equal to the width and length of the plate to be stacked by rotating the distance adjusting screw rod. When the telescopic cylinder drives the side connecting pressure plate to move downward, the side connecting pressure plate will press the movable frame. At this time, the movable frame will move the movable clamping plate to a position away from the center of the positioning frame through the oblique connecting pressure rod, so that the vertical section of the T-type sleeve block fits the plate, thereby correcting the plate that has just fallen above the plate placement plate, thereby preventing the plates from being misaligned during stacking, and further improving the stability of the plates after stacking;

[0023] 3. By setting a one-way reset part, when the plate placing plate is placed on the top of the supporting support plate, the limit pressure plate moves downward relative to the supporting support plate due to the pressure of the plate placing plate, so that the solenoid valve is energized and closed; when the pressure roller presses the plate on the plate placing plate, the supporting support plate moves downward relative to the guide column, the first telescopic spring stretches, and the piston rod moves downward with the limit slide plate. At this time, the aqueous solution inside the water tank will enter the inner side of the sleeve through the hose, the one-way valve, and the guide hole under the action of negative pressure, so as to prevent the first telescopic spring from driving the supporting support plate to rise and recover after the supporting support plate moves down; after the plate stacking is completed, the stacked plates are removed together with the plate placing plate, the solenoid valve is powered off and opened, and the aqueous solution inside the sleeve will have flow space, and when the first telescopic spring contracts and recovers, the supporting support plate will slowly move up, so as to restore the supporting support plate, thereby providing convenience for the subsequent stacking of plates.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0036] See also Figures 1 to 9 In an embodiment of the present invention, a board stacking device for furniture processing includes a support frame 1, a positioning frame 612 is installed on the top of the support frame 1, a guide column 2 is installed on the inner side of the support frame 1 through bolts, a limiting slide 603 is movably sleeved on the guide column 2, a support pallet 3 located below the positioning frame 612 is installed on the limiting slide 603, a one-way reset member is provided on the support pallet 3, telescopic cylinders 610 are installed on both sides of the support frame 1, the extended end of the telescopic cylinder 610 is connected to a side connecting pressure plate 613, a movable frame 601 located above the positioning frame 612 is provided on the side connecting pressure plate 613, a pressure plate shifting member is provided on the inner side of the movable frame 601, the movable frame 601 is connected to a guide roller 5 through the pressure plate shifting member, a correction limiting unit is installed on the inner side of the positioning frame 612, and a board placement plate 4 is placed on the top of the support pallet 3.

[0037] In this embodiment: when stacking the plates, the support frame 1 is first placed at one end of the plate conveyor belt so that the guide roller 5 and the conveyor belt are at the same horizontal height. Then, the correction limit unit is operated according to the length and width of the plate, and the plate placement plate 4 is placed on the top of the support plate 3. As the conveyor belt operates, the plate is completely moved onto the guide roller 5, and the telescopic cylinder 610 is started. The side connecting pressure plate 613 drives the movable frame 601 to move downward through the contraction of the telescopic cylinder 610. In this process, the plate is dropped to the top of the plate placement plate 4 through the pressure plate shifting member. During the process, the platen shifting member cooperates with the one-way reset member to make the platen fall to the top of the platen placement plate 4, and at the same time, the support plate 3 is moved downward, and then the guide roller 5 is restored by extending the movable frame 601. In this process, the platen placed on the top of the platen placement plate 4 is limited by the correction limit unit, and when the subsequent platen falls onto the guide roller 5, the telescopic cylinder 610 is started again, so that when the telescopic cylinder 610 is contracted, the platen shifting member is used to make the platen fall above the top plate of the platen placement plate 4, so as to prevent the plates from being damaged by friction during stacking.

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The pressure plate shifting member includes a limiting column 623 installed on both sides of the movable frame 601, and two guide sliders 614 are movably sleeved on the limiting column 623. The two guide sliders 614 are symmetrically arranged along the vertical center axis of the limiting column 623. The guide roller 5 is installed on one side of the guide slider 614, and a second telescopic spring 615 located on the outside of the limiting column 623 is installed between the two guide sliders 614. A clamping column 616 is installed on the side of the guide slider 614 away from the guide roller 5. A positioning guide frame 622 is installed on the top of the clamping frame 612, and a side connecting frame 625 is installed on the side of the positioning guide frame 622 away from the guide slider 614. A rectangular plug rod 626 is inserted on the side connecting frame 625, and a triangular stop block 628 located on the inner side of the positioning guide frame 622 is installed on the top of the rectangular plug rod 626. A return spring 627 connected to the side connecting frame 625 is arranged on the rectangular plug rod 626, and a pressure roller 624 is arranged at the bottom of the guide roller 5.

[0039] When the support plate 3 is supported by the guide roller 624, the support plate 3 is pressed downward relative to the guide column 2. At the same time, the positioning column 616 moves along the vertical section of the inner wall of the positioning guide frame 622. As the telescopic cylinder 610 contracts, when the positioning column 616 moves to the inclined section at the bottom of the positioning guide frame 622, the positioning column 616 moves along the bottom inclined section of the positioning guide frame 622 toward the two ends of the limiting column 623, so that the two guide sliders 614 on the limiting column 623 drive the guide roller 5 to move in the opposite direction. In this way, the plate on the guide roller 5 loses the support of the guide roller 5 and is stacked with the plate on the plate placing plate 4. The positioning column 616 moves along the vertical section of the inner wall of the positioning guide frame 622. When the bottom inclined surface of the guide frame 622 moves, it will squeeze the inclined surface of the triangular stop block 628, so that the triangular stop block 628 can move up relative to the side connecting frame 625. When the positioning column 616 moves to one side of the vertical surface of the triangular stop block 628, the triangular stop block 628 is restored under the action of the return spring 627, and the positioning column 616 is blocked and limited. When the telescopic cylinder 610 is extended, the positioning column 616 moves up along the vertical surface of the triangular stop block 628. When the positioning column 616 moves above the triangular stop block 628, the positioning column 616 will shrink and recover under the action of the elastic restoring force of the second telescopic spring 615. At this time, the guide roller 5 moves to the initial position with the extension of the telescopic cylinder 610, and then the plate on the conveyor belt will fall onto the guide roller 5 again. This repetition can realize the stacking of the plates, prevent large-area friction between the plates during the stacking process, thereby preventing the plates from being damaged during the stacking process.

[0040] Please refer to Figure 3 , Figure 4 There are four positioning guide frames 622 , which are evenly divided into two groups. The two positioning guide frames 622 in each group are symmetrically arranged along the transverse center axis of the positioning frame 612 .

[0041] In this embodiment: by setting this structure, when the telescopic cylinder 610 is contracted, the two guide sliders 614 on the limit column 623 drive the guide rollers 5 to move toward the two ends of the limit column 623, so that the plate on the guide rollers 5 loses support, causing the plate to fall vertically above the supporting plate 3.

[0042] Please refer to Figure 1 , Figure 3 , Figure 5 , Figure 6The correction limit unit includes a movable splint 621 extending from the outside of the positioning frame 612 to the inside of the positioning frame 612, and the movable splint 621 is inserted on all four sides of the positioning frame 612. The side of the movable splint 621 away from the positioning frame 612 is rotatably connected to an adjustable screw rod 619 extending to the inside of the movable splint 621 through a bearing, and the adjustable screw rod 619 is movably sleeved with a T-shaped sleeve block 629 extending to one end of the movable splint 621 away from the adjustable screw rod 619. The two sides of the movable splint 621 are provided with a third telescopic spring 620 connected to the positioning frame 612, and the top of the movable splint 621 is rotatably connected to an oblique connecting pressure rod 617 through a rotating shaft, and the top of the oblique connecting pressure rod 617 is rotatably connected to a movable frame 618 located below the side connecting pressure plate 613 through a rotating shaft.

[0043] In this embodiment: when stacking the plates, first rotate the distance-adjusting screw rod 619, and the T-shaped sleeve block 629 is moved relative to the movable clamping plate 621 by rotating the distance-adjusting screw rod 619, so that the distance from the vertical section of the T-shaped sleeve block 629 to the center of the positioning frame 612 can be adjusted, so as to adjust the distance between the two T-shaped sleeve blocks 629 symmetrically arranged along the vertical central axis of the positioning frame 612 to be equal to the length of the plates to be stacked, and similarly adjust the distance between the other two T-shaped sleeve blocks 629 to be equal to the width of the plates to be stacked, and when the telescopic cylinder 610 drives the side connecting pressure plate 613 to move downward, the side connecting pressure plate 613 will press the movable frame 618, and the movable frame 618 will move the movable clamp 621 to a position away from the center of the positioning frame 612 through the oblique connecting pressure rod 617. After the plate is placed, when the telescopic cylinder 610 is extended, the movable clamp 621 will be restored under the elastic restoring force of the third telescopic spring 620, so that the vertical section of the T-shaped sleeve block 629 is in contact with the plate, so as to correct the plate that has just fallen above the plate placement plate 4, thereby preventing the plates from being misaligned during stacking, and further improving the stability of the plates after stacking.

[0044] Please refer to Figure 5 The length of the inner wall of the top cross section of the movable frame 618 is greater than the length of the outer wall of the cross section of the locking frame 612 , and the width of the inner wall of the top cross section of the movable frame 618 is greater than the width of the outer wall of the cross section of the locking frame 612 .

[0045] In this embodiment: this structure is provided to prevent the movable frame 618 from hindering the movement of the movable frame 601.

[0046] Please refer to Figure 5 , Figure 6 The inner side of the T-shaped sleeve block 629 is provided with a threaded hole matching the pitch-adjusting screw rod 619 , and the inner side of the movable clamping plate 621 is provided with a through hole matching the horizontal section of the T-shaped sleeve block 629 .

[0047] In this embodiment: by providing this structure, when the pitch-adjusting screw rod 619 rotates, the T-shaped sleeve block 629 moves horizontally along the pitch-adjusting screw rod 619 , so as to accurately adjust the position of the T-shaped sleeve block 629 .

[0048] Please refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 The one-way reset member includes a water tank 606 installed on both sides of the support frame 1 and located on the side of the telescopic cylinder 610 close to the support frame 1. The top of the limiting slide plate 603 is installed with a first telescopic spring 604 connected to the support frame 1 and located on the outside of the guide column 2. The telescopic cylinder 610 is installed with a sleeve 611 on the side away from the support frame 1. The sleeve 611 is plugged with a piston rod 632 extending to the bottom of the sleeve 611. The bottom end of the piston rod 632 is connected to a guide pipe 608. The inner side of the piston rod 632 is provided with a guide hole 633. The guide pipe 608 is connected to the piston rod 632. A one-way valve 630 and a solenoid valve 631 connected to the guide tube 608 are respectively provided on both sides of the tube 608, a hose 607 connected to the water tank 606 is provided at the bottom of the guide tube 608, a limiting pressure plate 605 extending to the inner side of the support tray 3 is inserted at the top of the support tray 3, a fourth telescopic spring 634 connected to the inner wall of the support tray 3 is provided on the limiting pressure plate 605, a second contact piece 609 is provided on the inner wall of the support tray 3, and a first contact piece 602 located above the second contact piece 609 is provided at the bottom of the limiting pressure plate 605.

[0049] In this embodiment: when the sheet placing plate 4 is placed on the top of the supporting support plate 3, the limiting pressure plate 605 moves downward relative to the supporting support plate 3 due to the pressure of the sheet placing plate 4, so that the first contact piece 602 contacts the second contact piece 609, so that the solenoid valve 631 is energized and closed. When the pressure roller 624 presses the sheet on the sheet placing plate 4, the supporting support plate 3 moves downward relative to the guide column 2, the first telescopic spring 604 stretches, and the piston rod 632 moves downward with the limiting slide plate 603. At this time, the aqueous solution inside the water storage tank 606 will enter the inner side of the sleeve 611 through the hose 607, the one-way valve 630, and the guide hole 633 under the action of negative pressure. At the same time, the one-way valve 630 will block the aqueous solution inside the sleeve 611. Flow, preventing the aqueous solution inside the sleeve 611 from being discharged through the one-way valve 630, thereby preventing the first telescopic spring 604 from driving the support plate 3 to rise and recover after the support plate 3 moves down. After the stacking of the plates is completed, the stacked plates are removed together with the plate placing plate 4. At this time, the limit pressure plate 605 rises relative to the support plate 3 under the action of the elastic restoring force of the fourth telescopic spring 634, thereby separating the second contact piece 609 from the first contact piece 602, and at the same time, the solenoid valve 631 is powered off and opened. At this time, the aqueous solution inside the sleeve 611 will have flow space, and when the first telescopic spring 604 shrinks and recovers, the support plate 3 will slowly move up, thereby restoring the support plate 3, thereby facilitating the subsequent stacking of the plates.

[0050] Please refer to Figure 2 , Figure 7 , Figure 8 , Fig. 9 The second contact piece 609 is electrically connected to the external power supply through a wire, and the first contact piece 602 is electrically connected to the solenoid valve 631 through a wire.

[0051] In this embodiment, by providing this structure, the electromagnetic valve 631 is energized or de-energized when the first contact piece 602 and the second contact piece 609 are in contact or separated, thereby controlling the opening timing of the electromagnetic valve 631.

[0052] Please refer to Figure 8 The liquid inlet of the one-way valve 630 faces the hose 607 , and the liquid outlet faces the sleeve 611 .

[0053] In this embodiment: by setting this structure, when the solenoid valve 631 is in a closed state, the aqueous solution inside the sleeve 611 cannot be discharged into the water storage tank 606 through the one-way valve 630, thereby limiting the support plate 3 after it moves downward.

[0054] In combination with the above-mentioned furniture processing plate stacking equipment, a method for stacking furniture processing plate is provided, which specifically includes the following steps:

[0055] S1: First, place the support frame 1 at one end of the plate conveyor belt so that the guide roller 5 and the conveyor belt are at the same level;

[0056] S2: Rotate the pitch-adjusting screw 619 to move the T-shaped sleeve 629 relative to the movable clamping plate 621, so that the distance from the vertical section of the T-shaped sleeve 629 to the center of the positioning frame 612 can be adjusted, so that the distance between the two T-shaped sleeves 629 symmetrically arranged along the vertical central axis of the positioning frame 612 is adjusted to be equal to the length of the plate to be stacked, and similarly, the distance between the other two T-shaped sleeves 629 is adjusted to be equal to the width of the plate to be stacked;

[0057] S3: The sheet placing plate 4 is placed on the top of the supporting plate 3. The limiting pressing plate 605 is pressed by the sheet placing plate 4 and moves downward relative to the supporting plate 3, so that the first contact piece 602 contacts the second contact piece 609, thereby energizing and closing the solenoid valve 631.

[0058] S4: With the operation of the conveyor belt, the plate is completely moved onto the guide roller 5, and the telescopic cylinder 610 is started. When the telescopic cylinder 610 contracts, the movable frame 601 is driven to move downward through the side connecting pressure plate 613. At this time, the guide roller 5 moves downward with the movable frame 601. At this time, the pressure roller 624 presses the plate placed on the top of the plate placing plate 4. At the same time, the supporting plate 3 moves downward relative to the guide column 2 under the action of the one-way reset member. At the same time, the positioning column 616 moves along the inner side of the positioning guide frame 622. The vertical section of the wall moves, and as the telescopic cylinder 610 contracts, when the positioning column 616 moves to the inclined section at the bottom of the positioning guide frame 622, the positioning column 616 will move along the bottom inclined section of the positioning guide frame 622 toward the two ends of the limiting column 623, so that the two guide sliders 614 on the limiting column 623 drive the guide roller 5 to move in the opposite direction, so that the plate on the guide roller 5 can be stacked with the plate on the plate placement plate 4 due to the loss of support from the guide roller 5;

[0059] S5: When the pressure roller 624 presses the plate on the plate placing plate 4, the support plate 3 moves downward relative to the guide column 2, and the first telescopic spring 604 stretches, and at the same time the piston rod 632 moves downward along with the limiting slide plate 603. At this time, the aqueous solution inside the water storage tank 606 will enter the inner side of the sleeve 611 through the hose 607, the one-way valve 630, and the guide hole 633 under the action of negative pressure. At the same time, the one-way valve 630 will block the aqueous solution inside the sleeve 611 to prevent the aqueous solution inside the sleeve 611 from being discharged through the one-way valve 630, so as to prevent the first telescopic spring 604 from driving the support plate 3 to rise and recover after the support plate 3 moves downward. When the cylinder 610 drives the side connecting pressure plate 613 to move downward, the side connecting pressure plate 613 will press the movable frame 618. At this time, the movable frame 618 will move the movable clamping plate 621 to a position away from the center of the clamping frame 612 through the oblique connecting pressure rod 617. After the plate is placed, when the telescopic cylinder 610 is extended, the movable clamping plate 621 will be restored under the elastic restoring force of the third telescopic spring 620, so that the vertical section of the T-shaped sleeve block 629 is fitted with the plate, so as to correct the plate that has just fallen above the plate placing plate 4, thereby preventing the plates from being misaligned during stacking, and further improving the stability of the plates after stacking;

[0060] S6: When the telescopic cylinder 610 is extended, the positioning column 616 moves upward along the vertical surface of the triangular stop block 628. When the positioning column 616 moves to above the triangular stop block 628, the positioning column 616 will shrink and recover under the action of the elastic restoring force of the second telescopic spring 615. At this time, the guide roller 5 moves to the initial position as the telescopic cylinder 610 is extended. Then the plates on the conveyor belt will fall onto the guide roller 5 again. This can be repeated to achieve stacking of the plates, thereby preventing large-area friction between the plates during the stacking process, thereby preventing the plates from being damaged during the stacking process.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
