Description

Technical Field

[0001] This utility model relates to the field of wood panel stacking technology, and in particular to a wood panel stacking device. Background Technology

[0002] Before the furniture assembly and production process, the wood needs to be cut into boards of appropriate size. The cut boards then need to undergo a series of processes such as sanding, printing, and waxing before the furniture can be assembled and produced.

[0003] However, after the general board processing is completed, it is transported to the stacking position by a conveyor belt, and then the board is picked up by a lifting device with suction cups and stacked. This method is prone to the boards being stacked unevenly, resulting in wasted space, and the stacked boards are prone to tipping over. Therefore, a wood board stacking device is proposed.

[0017] This embodiment relates to a wooden board stacking device, the overall structure of which is as follows: Figure 1 , Figure 2 and Figure 4 As shown, it includes a gantry frame 1, a traveling device 2, a lifting device 3, and a correction device 4.

[0018] The traveling device 2 is slidably mounted on the top of the gantry frame 1, the lifting device 3 is lifted and lowered on the traveling device 2, and the correction device 4 is fixedly mounted on the cross brace at the bottom of the lifting device 3. The correction device 4 includes a mounting plate 401 fixedly mounted on the cross brace at the bottom of the lifting device 3, and a support crossbar 402 slidably mounted on both ends of the bottom of the mounting plate 401. The support crossbar 402 is rotatably mounted on the two ends of the support crossbar 403. The bottom of the axle 403 is fixedly mounted with two support rods 404 at 90°. The bottom of the support rod 404 away from the axle 403 is rotatably mounted with a correction wheel 405.

[0019] It is worth mentioning that both the walking device 2 and the lifting device 3 are equipped with drive motors, which are used to drive the walking device 2 to move back and forth on the top track of the gantry frame 1 and the lifting device 3 to move up and down on the walking device 2, respectively, so as to realize the reciprocating movement of the walking device 2 between the infeed conveyor belt 5 and the outfeed conveyor belt 6. Multiple vacuum suction cups are installed at the bottom corners of the lifting device 3 to achieve precise gripping and stable handling of the wood boards. The correction device 4 is fixedly installed at the bottom of the lifting device 3 to correct the wood boards in the length direction of the gantry frame 1, so that the wood boards are more neat after stacking. The mounting plate 401 is fixedly installed on the top of the bottom cross brace of the lifting device 3 to provide a stable base for the installation of the support crossbar 402. Both support rods 404 are at a 90° angle to the shaft 403, and the two support rods 404 are also at a 90° angle to each other. The correction wheel 405 is rotatably installed at the bottom of the support rod 404 to correct the wood boards when stacking, so that the wood boards are stacked more neatly.

[0020] As a preferred option, it remains as follows Figure 4 As shown, in this embodiment, a cylinder 406 is fixedly installed on one side of the bottom middle position of the mounting plate 401. The output end of the cylinder 406 is fixedly installed on one of the support crossbars 402. A fixed shaft 407 is fixedly installed at the bottom center position of the mounting plate 401. A pull plate 408 is rotatably installed on the fixed shaft 407. A first convex shaft 409 is fixedly installed at the bottom of both ends of the pull plate 408. A second convex shaft 410 is fixedly installed at the bottom middle position of the support crossbar 402. A pull rod 411 is rotatably installed between the first convex shaft 409 and the second convex shaft 410.

[0021] It should be noted that the output end of the cylinder 406 is fixedly installed together with one of the support crossbars 402, providing power for the movement of the two support crossbars 402 toward each other or away from each other. The fixed shaft 407 is fixedly installed at the bottom center of the mounting plate 401 for the rotational installation of the pull plate 408. A cylindrical through slot is opened through the center of the pull plate 408, and the pull plate 408 is rotatably installed on the fixed shaft 407 through the cylindrical through slot. The two ends of the pull rod 411 are rotatably installed on the first convex shaft 409 and the second convex shaft 410 respectively, realizing the linkage connection between the pull plate 408 and the support crossbar 402.

[0022] As a preferred option, it remains as follows Figure 4 As shown, in this embodiment, two sets of slide rails 412 are symmetrically arranged at the middle positions on both sides of the bottom of the mounting plate 401. There are two slide rails 412 in each set, and they are symmetrically arranged about the center line of the length direction of the mounting plate 401. Slider blocks 413 are fixedly arranged on both sides at the middle position of the top of the support crossbar 402. The sliders 413 are slidably arranged on the slide rails 412.

[0023] Specifically, each set of slide rails 412 consists of two slide rails, which are used to install sliders 413 on the corresponding support crossbars 402. The sliders 413 are welded to the support crossbars 402 and slide along the slide rails 412 with the support crossbars 402, guiding the movement path of the support crossbars 402. The slide rails 412 are fixedly installed with baffles at both ends to limit the movement of the sliders 413.

[0024] As a preferred option, it remains as follows Figure 2 As shown, in this embodiment, the support crossbar 402 has through-grooves 414 at both ends, and a torsion spring 415 is fixedly installed in the through-grooves 414. The shaft 403 is rotatably installed in the through-grooves 414, and the torsion spring 415 is installed on the shaft 403.

[0025] Specifically, the mounting slot 414 is formed through both ends of the support crossbar 402 for mounting the shaft 403 and the torsion spring 415. The torsion spring 415 is fitted onto the shaft 403, with one end fixedly installed in the mounting slot 414 of the support crossbar 402 and the other end fixed to the shaft 403 and rotating synchronously with the shaft 403. The elastic potential energy of the torsion spring 415 provides a rotational reset torque for the shaft 403 after rotation, so that the shaft 403 returns to its initial state when the external force is lost.

[0026] As a preferred option, it remains as follows Figure 1 As shown, in this embodiment, a feeding conveyor belt 5 is fixedly installed on one side of the bottom of the gantry frame 1, and a discharging conveyor belt 6 is fixedly installed on the other side of the bottom of the gantry frame 1. A correction plate 501 is fixedly installed on the top of the feeding conveyor belt 5 near the end of the gantry frame 1.

[0027] Specifically, the feeding conveyor belt 5 is installed at one end of the bottom of the gantry frame 1 to transport the wood boards to be stacked. The correction plate 501 is installed on the top of the feeding conveyor belt 5 located near one end of the gantry frame 1 to perform preliminary correction on the side of the wood boards near the correction plate 501, so as to facilitate the secondary correction of the wood boards by the correction device 4. The discharge conveyor belt 6 is located at the other end of the bottom of the gantry frame 1 to transport the stacked wood boards to the designated position.

[0028] As a preferred option, it remains as follows Figure 1 As shown in this embodiment, a feeding device 7 is fixedly installed at the middle position on one side of the gantry frame 1. The feeding device 7 is fixedly installed on the top of the discharge conveyor belt 6. A fork 701 is lifted and lowered on the feeding device 7. An opening slot 601 is opened on the side of the discharge conveyor belt 6 near the fork 701.

[0029] Specifically, the feeding device 7 and the discharge conveyor belt 6 are located on the same side of the gantry frame 1. The discharge conveyor belt 6 is used to transport the stacked wood boards to a designated location for storage. The forks 701 on the feeding device 7 are used to stack the wood boards. The opening slot 601 is opened at the corresponding position of the discharge conveyor belt 6 and the forks 701, so that the fork plates of the forks 701 correspond to the opening slot 601 in a vertical position.

[0030] Working principle: After the wood board is conveyed to the correction plate 501 on the feeding conveyor belt 5, the lifting device 3 moves downward on the walking device 2 so that the vacuum suction cup at the bottom of the wood board can grab it and then rise to the initial height.

[0031] The walking device 2 then moves along the track of the gantry frame 1 from one end of the feeding conveyor belt 5 to the unloading station at one end of the preset discharge conveyor belt 6. The lifting device 3 then moves down again to place the wood board on the fork 701, and the vacuum suction cup releases the negative pressure.

[0032] like Figure 1 As shown, the telescopic rod of cylinder 406 then retracts, driving the two side support crossbars 402 to move towards each other. At this time, the correction wheel 405 at the bottom of each shaft 403, which is close to the wood board, first corrects the wood board in the length direction of the gantry frame 1. When the torsion spring 415 is in its natural state, the correction wheels 405 at both ends of the wood board in the length direction of the gantry frame 1 abut against the wood board, thus completing the correction of the board in the length direction of the gantry frame 1.

[0033] like Figure 3 As shown, the support crossbar 402 then moves inward continuously, and the fixed end of the torsion spring 415 on the shaft 403 begins to rotate with the shaft 403. At this time, the correction wheel 405 at the bottom of each shaft 403, which is away from the wood board, corrects the wood board in the width direction of the gantry 1. When the two correction wheels 405 at the bottom of each shaft 403 are pressed against the side of the wood board, the correction of the wood board stacking is completed.

[0034] The telescopic rod of cylinder 406 then extends and returns to its initial state. The two support crossbars 402 return to their initial state in opposite directions. The correction wheel 405 separates from the wood board. Under the action of torsion spring 415, shaft 403 returns to its initial state. Lifting device 3 moves upward to its initial position. Then, walking device 2 moves to the preset station directly above the feeding conveyor belt 5 to complete one wood board picking and stacking operation. The above steps are repeated to stack the wood boards.

[0035] After the wood planks on the forks 701 are stacked, the forks 701 move downward under the power of the drive motor of the discharge conveyor belt 6, so that the wood planks are placed on the discharge conveyor belt 6.

[0036] The drive motors and cylinders 406 on the walking device 2, lifting device 3 and unloading device 7 are electrically connected to the control system. The corresponding operating parameters are set in the control system to ensure that the drive motors and cylinders 406 on the walking device 2, lifting device 3 and unloading device 7 operate in a coordinated and stable manner, thus ensuring the stability and efficiency of stacking wood panels.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
